Few persons have any idea of the great value and importance of the
products of our orchards and fruit-gardens. These are generally
considered the small things of agriculture, and are overlooked by all
but the statist, whose business it is to deal with these minutiæ, to
hunt them up, to collocate them, and when he combines these various
details and produces the sum total, we are all astonished at the
result.
Our government wisely provides for the gathering of statistics at
intervals of ten years, and some of the States also take an account of
stock and production at intermediate periods, some of them, like Ohio,
have a permanent statistician who reports annually to the Governor of
the State.
Our Boards of Trade publish the amounts of the leading articles that
arrive at and depart from the principal cities, and thus they furnish
us much additional information of value. Besides this, the county
assessors are sometimes directed to collect statistics upon certain
points of interest, and now that we all contribute toward the
extinction of the national debt, the United States Assessors in the
several districts are put in possession of data, which should be very
correct, in regard to certain productions that are specified by act of
Congress as liable to taxation. By these several means we may have an
opportunity of learning from time to time what are the productions of
the country, and their aggregate amounts are surprising to most of us.
When they relate to our special interests, they are often very
encouraging. This is particularly the case with those persons who have
yielded to the popular prejudice that cotton was the main agricultural
production of the United States; to such it will be satisfactory to
learn that the crop of corn, as reported in the last census, is of
nearly equal value, at the usual market prices of each article.
Fruit-growers will be encouraged to find that the value of orchard
products, according to the same returns, was nearly twenty millions,
that of Ohio being nearly one million; of New York, nearly three and
three-quarters millions; that the wine crop of the United States, an
interest that is still in its infancy, amounted to nearly three and
one-quarter millions; and that the valuation of market garden products
sums up to more than sixteen millions of dollars' worth. It is to be
regretted that for our present purpose, the data are not sufficiently
distinct to enable us to ascertain the relative value of the
productions of our orchards of apples, pears, peaches, quinces, and
the amount and value of the small fruits, as they are termed, since
these are variously grouped in the returns of the census takers, and
cannot now be separated. Of their great value, however, we may draw
our conclusions from separate records that have been kept and reported
by individuals, who assert the products of vineyards in some cases to
have been as high as three thousand dollars per acre; of strawberries,
at one thousand dollars; of pears, at one hundred dollars per tree,
which would be four thousand dollars per acre; of apples, at
twenty-five bushels per tree, or one thousand bushels per acre, which,
at fifty cents per bushel, would produce five hundred dollars.
But, leaving this matter of dollars and cents, who will portray for us
the delights incident to fruit-culture? They are of a quiet nature,
though solid and enduring. They carry us back to the early days of the
history of our race, when "the Lord God planted a garden eastward in
Eden ... and out of the ground made the Lord God to grow every tree
that is pleasant to the sight, and good for food ... and the Lord God
took the man and put him into the garden of Eden, to dress it and to
keep it." We are left to infer that this dressing and keeping of the
garden was but a light and pleasant occupation, unattended with toil
and trouble, and that in their natural condition the trees and
plants, unaided by culture, yielded food for man. Those were
paradisean times, the days of early innocence, when man, created in
the image of his Maker, was still obedient to the divine commands;
but, after the great transgression, everything was altered, the very
ground was cursed, "thorns and thistles shall it bring forth to thee,
and thou shalt eat of the herb of the field. In the sweat of thy face
shalt thou eat bread."----From that day to the present hour it has
been the lot of man to struggle with difficulties in the cultivation
of the soil, and he has been driven to the necessity of constant
watchfulness and care to preserve and to improve the various fruits of
the earth upon which he subsists. In the tropics, it is true, there
are many vegetable productions which are adapted for human food, even
in a state of nature, and there we find less necessity for the effort
of ingenuity and the application of thought and labor to produce a
subsistence. Amid these productive _plants of nature_, the natives of
such regions lead an idle life, and seldom rise above a low scale of
advancement; but in the temperate regions of the globe, where the
unceasing effort of the inhabitants is required to procure their daily
food, we find the greatest development of human energies and
ingenuity--there man thinks, and works; there, indeed, he is forced to
improve the natural productions of the earth--and there we shall find
him progressing. As with everything else, so it is with fruits, some
of which were naturally indifferent or even inedible, until subjected
to the meliorating influences of high culture, of selection, and of
improvement. Here we find our _plants of culture_, which so well repay
the labor and skill bestowed upon them.
In the early periods of the history of our race, while men were
nomadic and wandered from place to place, little attention was paid to
any department of agricultural improvement, and still less care was
bestowed upon horticulture. Indeed, it can scarcely be supposed that,
under such conditions, either branch of the art could have existed,
any more than they are now found among the wandering hordes of Tartars
on the steppes of Asia. So soon, however, as men began to take
possession of the soil by a more permanent tenure, agriculture and
horticulture also, attracted their chief attention, and were soon
developed into arts of life. With advancing civilization, this has
been successively more and more the case; the producing art being
obliged to keep pace with the increased number of consumers, greater
ingenuity was required and was applied to the production of food for
the teeming millions of human beings that covered the earth, and, as
we find, in China, at the present time, the greatest pains were taken
to make the earth yield her increase.
High civilization demands high culture of the soil, and agriculture
becomes an honored pursuit, with every department of art and science
coming to its assistance. At the same time, and impelled by the same
necessities, supported and aided by the same co-adjutors, horticulture
also advances in a similar ratio, and, from its very nature, assumes
the rank of a fine art, being less essential than pure agriculture,
and in some of its branches being rather an ornamental than simply a
useful art. It is not admitted, however, that any department of
horticulture is to be considered useless, and many of its applications
are eminently practical, and result in the production of vast
quantities of human food of the most valuable kind. This pursuit
always marks the advancement of a community.--As our western pioneers
progress in their improvements from the primitive log cabins to the
more elegant and substantial dwelling houses, we ever find the garden
and the orchard, the vine-arbor and the berry-patch taking their
places beside the other evidences of progress. These constitute to
them the poetry of common life, of the farmer's life.
The culture of fruits, and gardens also, contributes in no small
degree to the improvement of a people by the excellent moral influence
it exercises upon them. Everything that makes home attractive must
contribute to this desirable end. Beyond the sacred confines of the
happy hearthstone, with its dear familiar circle, there can be no more
pleasant associations than those of the garden, where, in our tender
years, we have aided loved parents, from them taking the first lessons
in plant-culture, gathering the luscious fruits of their planting or
of our own; nor of the rustic arbor, in whose refreshing shade we have
reclined to rest and meditate amid its sheltering canopy of verdure,
and where we have gathered the purple berries of the noble vine at a
later period of the rolling year; nor of the orchard, with its
bounteous supplies of golden and ruddy apples, blushing peaches, and
melting pears. With such attractions about our homes, with such ties
to be sundered, it is wonderful, and scarcely credible, that youth
should ever be induced to wander from them, and to stray into paths of
evil. Such happy influences must have a good moral effect upon the
young. If it be argued that such luxuries will tend to degrade our
morals by making us effeminate and sybaritic, or that such enjoyments
may become causes of envy and consequent crime on the part of those
who are less highly favored, it may be safely asserted that there is
no better cure for fruit-stealing, than to give presents of fruit, and
especially of fruit-trees, to your neighbors, particularly to the
boys--encourage each to plant and to cherish his own tree, and he will
soon learn the meaning of _meum_ and _tuum_, and will appreciate the
beauties of the moral code, which he will be all the more likely to
respect in every other particular.
Some of the legislation of our country is a very curious relic of
barbarism. According to common law, that which is attached to the
soil, may be removed without a breach of propriety, by one who is not
an owner of the fee simple; thus, such removal of a vegetable product
does not constitute theft or larceny, but simply amounts to a
trespass: whereas the taking of fruit from the ground beneath the
tree, even though it be defective or decaying, is considered a theft.
An unwelcome intruder, or an unbidden guest, may enter our orchard,
garden, or vineyard, and help himself at his pleasure to any of our
fruits, which we have been most carefully watching and nursing tor
months upon trees, for the fruitage of which we may have been laboring
and waiting for years, and, forsooth, our only recourse is to sue him
at the law, and our only satisfaction, after all the attendant
annoyance and expense, is a paltry fine for _trespass_ upon our
freehold, which, of course, is not commensurate with our estimate of
the value of the articles taken: fruits often possess, in the eyes of
the devoted orchardist, a real value much beyond their market price.
Were I asked to describe the location of the fabled fountain of
Hygeia, I should decide that it was certainly situated in an orchard;
it must have come bubbling from earth that sustained the roots of tree
and vine; it must have been shaded by the umbrageous branches of the
wide-spreading apple and pear, and it was doubtless approached by
alleys that were lined by peach trees laden with their downy fruit,
and over-arched by vines bearing rich clusters of the luscious grape,
and they were garnished at their sides by the crimson strawberry. Such
at least would have been an appropriate setting for so valued a jewel
as the fountain of health, and it is certain that the pursuit of
fruit-growing is itself conducive to the possession of that priceless
blessing. The physical as well as the moral qualities of our nature
are wonderfully promoted by these cares. The vigorous exercise they
afford us in the open air, the pleasant excitement, the expectation of
the results of the first fruits of our plants, tending, training and
cultivating them the while, are all so many elements conducive to the
highest enjoyment of full health.
The very character of the food furnished by our orchards should be
taken into the account, in making up our estimate of their
contributions to the health of a community. From them we procure
aliment of the most refined character, and it has been urged that the
elements of which they are composed are perfected or refined to the
highest degree of organization that is possible to occur in vegetable
tissues. Such pabulum is not only gratefully refreshing, but it is
satisfying--without being gross, it is nutritious. The antiscorbutic
effects of ripe fruits, especially those that are acid, are
proverbial, and every fever patient has appreciated the relief derived
from those that are acidulous. Then as a preventive of the febrile
affections peculiar to a miasmatic region, the free use of acid
fruits, or even of good sound vinegar made from grapes or apples, is
an established fact in medical practice--of which, by the by,
prevention is always the better part.
Apples were esteemed an important and valuable article of food in the
days of the Romans, for all school boys have read in the ore rotundo
of his own flowing measures, what Virgil has said, so much better than
his tame translator:
"New cheese and chestnuts are our country fare,
With mellow apples for your welcome cheer."
But in more modern times, beside their wonted use as dessert fruit, or
evening feast, or cooked in various modes, a French economist "has
invented and practiced with great success a method of making bread
with common apples, which is said to be very far superior to
potato-bread. After having boiled one-third part of peeled apples, he
bruised them while quite warm into two-thirds parts of flour,
including the proper quantity of yeast, and kneaded the whole without
water, the juice of the fruit being quite sufficient; he put the mass
into a vessel in which he allowed it to rise for about twelve hours.
By this process he obtained a very excellent bread, full of eyes, and
extremely light and palatable."[1]
Nor is this class of food desirable for man alone. Fruits of all
kinds, but particularly what may be called the large fruits, such as
are grown in our orchards, may be profitably cultivated for feeding
our domestic animals. Sweet apples have been especially recommended
for fattening swine, and when fed to cows they increase the flow of
milk, or produce fat according to the condition of these animals.
Think of the luxury of eating apple-fed pork! Why, even the strict
Rabbi might overcome his prejudices against such swine flesh! And then
dream of enjoying the luxury of fresh rich milk, yellow cream, and
golden butter, from your winter dairy, instead of the sky-blue fluid,
and the pallid, or an anotto-tinted, but insipid butter, resulting
from the meager supplies of nutriment contained in dry hay and
fibrous, woody cornstalks. Now this is not unreasonable nor
ridiculous. Orchards have been planted with a succession of sweet
apples that will sustain swine in a state of most perfect health,
growing and fattening simultaneously from June to November; and the
later varieties may be cheaply preserved for feeding stock of all
kinds during the winter, when they will be best prepared by steaming,
and may be fed with the greatest advantage. Our farmers do not
appreciate the benefits of having green food for their animals during
the winter season. Being blessed with that royal grain, the Indian
corn, they do not realize the importance of the provision of roots
which is so great a feature in British husbandry; but they have yet to
learn, and they will learn, that for us, and under our conditions of
labor and climate, they can do still better, and produce still greater
results with a combination of _hay_ or _straw_, _corn meal_ and
_apples_, all properly prepared by means of steam or hot water.
Besides, such orchards may be advantageously planted in many places
where the soil is not adapted to the production of grain.--The reader
is referred to the chapter on select lists in another part of this
volume, in which an attempt will be made to present the reader with
the opinions of the best pomologists of various parts of the country.
It were an interesting and not unprofitable study to trace the various
sources and routes by which fruits have been introduced into different
parts of our extended country. In some cases we should find that we
were indebted for these luxuries to the efforts of very humble
individuals, while in other regions the high character of the orchards
is owing to the forethought, knowledge, enterprise, and liberality of
some prominent citizen of the infant community, who has freely spent
his means and bestowed his cares in providing for others as well as
for his own necessities or pleasures. But it is to the intelligent
nurserymen of our country that we are especially indebted for the
universal diffusion of fruits, and for the selection of the best
varieties in each different section. While acting separately, these
men were laboring under great disadvantages, and frequently cultivated
certain varieties under a diversity of names, as they had received
them from various sources. This was a difficulty incident to their
isolation, but the organization of Pomological Societies in various
parts of the country, has enabled them in a great measure to unravel
the confusion of an extended synonymy, and also by comparison and
consultation with the most intelligent fruit-growers, they have been
prepared to advise the planter as to the best and most profitable
varieties to be set out in different soils and situations.
Most of our first orchards were planted with imported trees. The
colonists brought plants and seeds. Even now, in many parts of the
country, we hear many good fruits designated as English, to indicate
that they are considered superior to the native; and we are still
importing choice varieties from Europe and other quarters of the
globe.
The roving tribes of Indians who inhabited this country when
discovered and settled by the whites, had no orchards--they lived by
the chase, and only gathered such fruits as were native to the soil.
Among the earliest attempts to civilize them, however, those that
exerted the greatest influence, were efforts to make them an
agricultural people, and of these the planting of fruit-trees was one
of the most successful. In many parts of the country we find relics of
these old Indian orchards still remaining, and it is probable that
from the apple seeds sent by the general government for distribution
among the Cherokees in Georgia, we are now reaping some of the most
valuable fruits of this species. The early French settlers were famous
tree-planters, and we find their traces across the continent, from the
St. Lawrence to the Gulf of Mexico. These consist in noble pear and
apple trees, grown from seeds planted by them, at their early and
scattered posts or settlements. These were made far in advance of the
pioneers, who have, at a later period, formed the van of civilization,
that soon spread into a solid phalanx in its march throughout the
great interior valley of the continent.
On the borders of civilization we sometimes meet with a singular
being, more savage than polished, and yet useful in his way. Such an
one in the early settlement of the northwestern territory was Johnny
Apple-seed--a simple-hearted being, who loved to roam through the
forests in advance of his fellows, consorting, now with the red man,
now with the white, a sort of connecting link--by his white brethren
he was, no doubt, considered rather a vagabond, for we do not learn
that he had the industry to open farms in the wilderness, the energy
to be a great hunter, nor the knowledge and devotion to have made him
a useful missionary among the red men. But Johnny had his use in the
world. It was his universal custom, when among the whites, to save the
seeds of all the best apples he met with. These he carefully preserved
and carried with him, and when far away from his white friends, he
would select an open spot of ground, prepare the soil, and plant these
seeds, upon the principle of the old Spanish custom, that he owed so
much to posterity, so that some day, the future traveler or inhabitant
of those fertile valleys, might enjoy the fruits of his early efforts.
Such was Johnny Apple-seed--did he not erect for himself monuments
more worthy, if not more enduring, than piles of marble or statues of
brass?
In tracing the progress of fruits through different portions of our
country, we should very naturally expect to find the law that governs
the movements of men, applying with equal force to the fruits they
carry with them. The former have been observed to migrate very nearly
on parallels of latitude, so have, in a great degree, the latter; and
whenever we find a departure from this order, we may expect to
discover a change, and sometimes a deterioration in the characters of
the fruits thus removed to a new locality. It is true, much of this
alteration, whether improvement or otherwise, may be owing to the
difference of soil. Western New York received her early fruits from
Connecticut, and Massachusetts; Michigan, Northern Illinois, and
later, Wisconsin and Iowa received theirs in a great degree from New
York. Ohio and Indiana received their fruits mainly from New Jersey,
and Pennsylvania, and we may yet trace this in the prevalence of
certain leading varieties that are scarcely known, and very little
grown on different parallels. The early settlement at the mouth of the
Muskingum river, was made by New England-men, and into the
"Ohio-purchase," they introduced the leading varieties of the apples
of Massachusetts. Among these, the Boston or Roxbury Russet was a
prominent favorite, but it was so changed in its appearance as
scarcely to be recognized by its old admirers, and it was christened
with a new name, the Putnam Russet, under the impression that it was a
different variety. Most of the original Putnam varieties have
disappeared from the orchards. Kentucky received her fruits in great
measure from Virginia; Tennessee from the same source and from North
Carolina, and these younger States sent them forward on the great
western march with their hardy sons to southern Indiana, southern
Illinois, to Missouri, and to Arkansas, in all which regions we find
evident traces in the orchards, of the origin of the people who
planted them.
Of course, we shall find many deflections from the precise parallel of
latitude, some inclining to the south, and many turning to the
northward. To the latter we of the West are looking with the greatest
interest, since we so often find that the northern fruits do not
maintain their high characters in their southern or southwestern
migrations, and all winter kinds are apt to become autumnal in their
period of ripening, which makes them less valuable; and because, among
those from a southern origin, we have discovered many of high merit as
to beauty, flavor, and productiveness--and, especially where they are
able to mature sufficiently, they prove to be long keepers, thus
supplying a want which was not filled by fruits of a northern origin.
There may be limits beyond which we cannot transport some sorts to
advantage in either direction, but this too will depend very much upon
the adaptability of our soils to particular varieties.
In every region where fruit has been cultivated we find local
varieties grown from seed, many of these are of sufficient merit to
warrant their propagation, and it behooves us to be constantly on the
look out for them; for though our lists are already sufficiently large
to puzzle the young orchardist in making his selections, we may well
reduce the number by weeding out more of the indifferent fruit, at the
same time that we are introducing those of a superior character. It
has been estimated that there may be as many as one in ten of our
seedling orchard trees that would be ranked as "good," but not one in
a hundred that could be styled "best."[2] Certain individuals have
devoted themselves to the troublesome though thankless office of
collecting these scattered varieties of decided merit, and from their
collections our pomological societies will, from time to time, select
and recommend the best for more extended cultivation. Such devoted men
as H.N. Gillett, Lewis Jones, Reuben Ragan, A.H. Ernst, who have been
industriously engaged in this good work for a quarter of a century,
are entitled to the highest commendation; but there are many others
who have contributed their full share of benefits by their labors in
the same field, to whom also we owe a debt of gratitude. Two of the
chief foci in the Ohio valley from which valuable fruits have been
distributed most largely, were the settlement at the mouth of the
Muskingum, with its Putnam list given below; and a later, but very
important introduction of choice fruits, brought into the Miami
country by Silas Wharton, a nurseryman from Pennsylvania, who settled
among a large body of the religious Society of Friends, in Warren Co.,
Ohio. The impress of this importation is very manifest in all the
country, within a radius of one hundred miles, and some of his fruits
are found doing well in the northwestern part of the State of Ohio, in
northern Indiana, and in an extended region westward.
There are, no doubt, many other local foci, whence good fruits have
radiated to bless regions more or less extensive, and in every
neighborhood we find the name of some early pomologist attached to the
good fruits that he had introduced, thus adding another synonym to the
numerous list of those belonging to so many of our good varieties.
A.W. Putnam commenced an apple nursery in 1794, a few years after the
first white settlement at Marietta, Ohio, the first grafts were set in
the spring of 1796; they were obtained from Connecticut by Israel
Putnam, and were the first set in the State, and grafted by W. Rufus
Putnam. Most of the early orchards of the region were planted from
this nursery. These grafts were taken from the orchard of Israel
Putnam (of wolf-killing memory) in Pomfret, Connecticut. In the Ohio
Cultivator for August 1st, 1846, may be found the following authentic
list of the varieties propagated:--
"1. Putnam Russet, (Roxbury.)
2. Seek-no-further, (Westfield.)
3. Early Chandler.
4. Gilliflower.
5. Pound Royal, (Lowell).
6. Natural, (a seedling).
7. Rhode Island Greening.
8. Yellow Greening.
9. Golden Pippin.
10. Long Island Pippin.
11. Tallman Sweeting.
12. Striped Sweeting.
13. Honey Greening.
14. Kent Pippin.
15. Cooper.
16. Striped Gilliflower.
17. Black, do.
18. Prolific Beauty.
19. Queening, (Summer Queen?)
20. English Pearmain.
21. Green Pippin.
22. Spitzenberg, (Esopus?)
Many of these have disappeared from the orchards and from the
nurserymen's catalogues."

In attempting to trace out the history of any plant that has long been
subjected to the dominion of man, we are beset with difficulties
growing out of the uncertainty of language, and arising also from the
absence of precise terms of science in the descriptions or allusions
which we meet respecting them. As he who would investigate the
history of our great national grain crop, the noble Indian maize,
which, in our language, claims the generic term corn, will at once
meet with terms apt to mislead him in the English translation of the
Bible, and in the writings of Europeans, who use the word corn in a
generic sense, as applying to all the edible grains, and especially to
wheat--so in this investigation we may easily be misled by meeting the
word apple in the Bible and in the translations of Latin and Greek
authors, and we may be permitted to question whether the original
words translated apple may not have been applied to quite different
fruits, or perhaps we may ask whether our word may not originally have
had a more general sense, meaning as it does, according to its
derivation, any round body.
The etymology of the word apple is referred by the lexicographers to
_abhall_, Celtic; _avall_, Welsh; _afall_ or _avall_, Armoric; _aval_
or _avel_, Cornish; and these are all traceable to the Celtic word
_ball_, meaning simply a round body.
Worcester traces the origin of apple directly to the German _apfel_,
which he derives from _æpl_, _apel_, or _appel_.
Webster cites the Saxon _appl_ or _appel_; Dutch, _appel_; German,
_apfel_; Danish, _æble_; Swedish, _aple_; Welsh, _aval_; Irish,
_abhal_ or _ubhal_; Armoric, _aval_; Russian, _yabloko_.
Its meaning being fruit in general, with a round form. Thus the
Persian word _ubhul_ means Juniper berries, and in Welsh the word used
means other fruits, and needs a qualifying term to specify the variety
or kind.
Hogg, in his British Pomology, quoting Owen, says, the ancient
Glastonbury was called by the Britons _Ynys avallac_ or _avallon_,
meaning an apple orchard, and from this came the Roman word
_avallonia_, from this he infers that the apple was known to the
Britons before the advent of the Romans. We are told, that in 973,
King Edgar, when fatigued with the labors of the chase, laid himself
down under a wild apple tree, so that it becomes a question whether
this plant was not a native of England as of other parts of Europe,
where in many places it is found growing wild and apparently
indigenous. Thornton informs us in his history of Turkey, that apples
are common in Wallachia, and he cites among the varieties one, the
_domniasca_, "which is perhaps the finest in Europe, both for its
size, color, and flavor." It were hard to say what variety this is,
and whether it be known to us.
The introduction of this word apple in the Bible is attributable to
the translators, and some commentators suggest that they have used it
in its general sense, and that in the following passages where it
occurs, it refers to the citron, orange, or some other subtropical
fruit.
"Stay me with flagons, comfort me with apples."--Songs of Solomon ii,
5.
"As the apple-tree (citron) among the trees of the wood, * * * I sat
me down under his shadow with great delight, and his fruit was sweet
to my taste."--Sol. ii, 2.
* * * "I raised thee up under the apple-tree."--Solomon viii, 5.
"A word fitly spoken, is like apples of gold in pictures of
silver."--Prov. xxv, 11.
The botanical position of the cultivated apple may be stated as
follows:--Order, _Rosaceæ_; sub-order, _Pomeæ_; or the apple family
and genus, _Pyrus_. The species under our consideration is the _Pyrus
Malus_, or apple. It has been introduced into this country from
Europe, and is now found in a half-wild state, springing up in old
fields, hedge-rows, and roadsides; but, even in such situations, by
their eatable fruit and broad foliage, and by the absence of spiny or
thorny twigs, the trees generally give evidence of a civilized origin.
It is not that the plant has changed any of its true specific
characters, but that it has been affected by the meliorating
influences of culture, which it has not been able entirely to shake
off in its neglected condition. Sometimes, indeed, trees are found in
these neglected and out-of-the-way situations, which produce fruits of
superior quality--and the sorts have been gladly introduced into our
nurseries and orchards.
Very early in the history of horticulture the apple attracted
attention by its improvability, showing that it belonged to the class
of culture-plants. Indeed it is a very remarkable fact in the study of
botany, and the pivot upon which the science and art of horticulture
turns, that while there are plants which show no tendency to change
from their normal type, even when brought under the highest culture,
and subjected to every treatment which human ingenuity can suggest,
there are others which are prone to variations or sports, even in
their natural condition, but more so when they are carefully nursed by
the prudent farmer or gardener. These may be called respectively the
plants of nature and the plants of culture. Some of the former furnish
human food, and are otherwise useful to man; but the latter class
embraces by far the larger number of food-plants, and we are indebted
to this pliancy, aided by human skill, for our varieties of fruits,
our esculent vegetables, and the floral ornaments of our gardens.
The native country of the apple, though not definitively settled, is
generally conceded to be Europe, particularly its southern portions,
and perhaps Western Asia: that is, the plant known and designated by
botanists as _Pyrus Malus_, for there are other and distinct species
in America and Asia which have no claims to having been the source of
our favorite orchard fruits. Our own native crab is the _Pyrus
coronaria_, which, though showing some slight tendency to variation,
has never departed from the strongly marked normal type. The _P.
baccata_, or Siberian crab, is so distinctly marked as to be admitted
as a species. It has wonderfully improved under culture, and has
produced some quite distinct varieties; it has even been hybridized by
Mr. Knight, with the cultivated sorts of the common Wilding or Crab of
Europe, the _P. Malus_. Pallas, who found it wild near Lake Baikal and
in Daouria, says, it grows only 3 or 4 feet high, with a trunk of as
many inches diameter, and yields pear-shaped berries as large as peas.
The _P. rivularis_, according to Nuttall, is common in the maritime
portions of Oregon, in alluvial forests. The tree attains a height of
15 to 25 feet. It resembles the Siberian Crab, to which it has a close
affinity. The fruit grows in clusters, is purple, scarcely the size of
a cherry, and of an agreeable flavor; sweetish and sub-acid when ripe,
not at all acid and acerb as the _P. coronaria_.[3]
Among the early writers upon the subject of pomology, we find some
very crude notions, particularly in regard to the wonderful powers of
the grafter, for this art of improving the Wilding by inserting buds
or scions of better sorts, and thus multiplying trees of good kinds,
was a very ancient invention. Pliny, the naturalist, certainly
deserves our praise for his wonderful and comprehensive industry in
all branches of natural history. In regard to grafting, which seems to
have been well understood in his day, he says, that he had seen near
Thuliæ a tree bearing all manner of fruits, nuts and berries, figs and
grapes, pears and pomegranates; no kind of apple or other fruit that
was not to be found on this tree. It is quaintly noted, however, that
"this tree did not live long,"--is it to be wondered that such should
have been the case? Now some persons may object to the testimony of
this remarkable man, and feel disposed to discredit the statement of
what appears so incredible to those who are at all acquainted with the
well-known necessity for a congenial stock into which the graft should
be inserted. But a more extended knowledge of the subject, would
explain what Pliny has recorded as a marvel of the art. The same thing
has been done in our own times, it is a trick, and one which would
very soon be detected now-a-days by the merest tyro in horticulture,
though it may have escaped the scrutiny of Pliny, whose business it
was to note and record the results of his observations, rather than to
examine the modus of the experiment. By the French, the method is
called Charlatan grafting, and is done by taking a stock of suitable
size, hollowing it out, and introducing through its cavity several
stocks of different kinds, upon each of which may be produced a
different sort of fruit, as reported by Pliny. The needed affinity of
the scion and stock, and the possible range that may be successfully
taken in this mode of propagation, with the whole consideration of the
influence of the stock upon the graft, will be more fully discussed in
another chapter.
Though it be claimed and even admitted that the wild apple or crab was
originally a native of Britain, and though it be well known that many
varieties have originated from seed in that country, still it appears
from their own historians that the people introduced valuable
varieties from abroad. Thus we find in Fuller's account, that in the
16th year of the reign of Henry VIII, Pippins were introduced into
England by Lord Maschal, who planted them at Plumstead, in Sussex.
After this, the celebrated Golden Pippin was originated at Perham
Park, in Sussex, and this variety has attained a high meed of praise
in that country and in Europe, though it has never been considered so
fine in this country as some of our own seedlings. Evelyn says, in
1685, at Lord Clarendon's seat, at Swallowfield, Berks, there is an
orchard of one thousand golden and other cider Pippins.[4] The Ribston
Pippin, which every Englishman will tell you is the best apple in the
world, was a native of Ribston Park, Yorkshire. Hargrave says: "This
place is remarkable for the produce of a delicious apple, called the
Ribston Park Pippin." The original tree was raised from a Pippin
brought from France.[5] This apple is well-known in this country, but
not a favorite.
At a later period, 1597, John Gerard issued in an extensive folio his
History of Plants, in which he mentions seven kinds of Pippins. The
following is given as a sample of the pomology of that day:--
"The fruit of apples do differ in greatnesse, forme, colour, and
taste, some covered with red skin, others yellow or greene, varying
infinitely according to soil and climate; some very greate, some very
little, and many of middle sort; some are sweet of taste, or something
soure, most be of middle taste between sweet and soure; the which to
distinguish, I think it impossible, notwithstanding I heare of one who
intendeth to write a peculiar volume of apples and the use of them."
He further says: "The tame and grafted apple trees are planted and set
in gardens and orchards made for that purpose; they delight to growe
in good fertile grounds. Kent doth abounde with apples of most sortes;
but I have seen pastures and hedge-rows about the grounds of a
worshipful gentleman dwelling two miles from Hereford, so many trees
of all sortes, that the seruantes drinke for the moste parte no other
drinke but that which is made of apples. * * * Like as there be divers
manured apples, so is there sundry wilde apples or crabs, not
husbanded, that is, not grafted." He also speaks of the Paradise,
which is probably the same we now use as a dwarfing stock.
Dr. Gerard fully appreciated the value of fruits, and thus vehemently
urges his countrymen to plant orchards: "Gentlemen, that have land and
living, put forward, * * * * * graft, set, plant, and nourish up trees
in every corner of your grounds; the labor is small, the cost is
nothing, the commoditie is great, yourselves shall have plentie, the
poor shall have somewhat in time of want to relieve their necessitie,
and God shall reward your good minde and diligence." The same author
gives us a peculiar use of the apple which may be interesting to some
who never before associated _pomatum_ with the products of the
orchard. He recommends apples as a cosmetic. "There is made an
ointment with the pulp of apples, and swine's grease and rose water,
which is used to beautify the face and to take away the roughness of
the skin; it is called in shops _pomatum_, of the apples whereof it is
made."[6] When speaking of the importance of grafting to increase the
number of trees of any good variety, Virgil advises to
"Graft the tender shoot,
Thy children's children shall enjoy the fruit."
So high an estimate did Pliny have of this fruit, that he asserted
that "there are apples that have ennobled the countries from whence
they came, and many apples have immortalized their first founders and
inventors. Our best apples will immortalize their first grafters
forever; such as took their names from Manlius, Cestius, Matius, and
Claudius."--Of the Quince apple, he says, that came of a quince being
grafted upon the apple stock, which "smell like the quince, and were
called _Appiana_, after Appius, who was the first that practiced this
mode of grafting. Some are so red that they resemble blood, which is
caused by their being grafted upon the mulberry stock. Of all the
apples, the one which took its name from Petisius, was the most
excellent for eating, both on account of its sweetness and its
agreeable flavor." Pliny mentions twenty-nine kinds of apples
cultivated in Italy, about the commencement of the Christian Era.[7]
Alas! for human vanity and apple glory! Where are now these boasted
sorts, upon whose merits the immortality of their inventors and first
grafters was to depend? They have disappeared from our lists to give
place to new favorites, to some of which, perhaps, we are disposed to
award an equally high meed of praise, that will again be ignored in a
few fleeting years, when higher skill and more scientific applications
of knowledge shall have produced superior fruit to any of those we now
prize so highly; and this is a consummation to which we may all look
forward with pleasure.
In this country the large majority of our favorite fruits, of whatever
species or kind, seem to have originated by accident, that is, they
have been discovered in seedling orchards, or even in hedge-rows.
These have no doubt, however, been produced by accidental crosses of
good kinds, and this may occur through the intervention of insects in
any orchard of good fruit, where there may chance to be some varieties
that have the tendency to progress. The discoveries of Linnæus, and
his doctrine of the sexual characters of plants, created quite a
revolution in botany, and no doubt attracted the attention of Lord
Bacon, who was a close observer of nature, for he ventured to guess
that there might be such a thing as crossing the breeds of plants,
when he says:--"The compounding or mixture of kinds in plants is not
found out, which, nevertheless, if it be possible, is more at command
than that of living creatures; wherefore it were one of the most
noteable experiments touching plants to find it out, for so you may
have great variety of new fruits and flowers yet unknown. Grafting
does it not, that mendeth the fruit or doubleth the flowers, etc., but
hath not the power to make a new kind, for the scion ever overruleth
the stock." In which last observation he shows more knowledge and a
deeper insight into the hidden mysteries of plant-life than many a man
in our day, whose special business it is to watch, nurse, and care for
these humble forms of existence.
Bradley, about a century later, in 1718, is believed to have been the
first author who speaks of the accomplishment of cross-breeding, which
he describes as having been effected by bringing together the branches
of different trees when in blossom. But the gardeners of Holland and
the Netherlands were the first to put it into practice.[8]
The following extract is given to explain the manner in which Mr.
Knight conducted his celebrated experiments on fruits, which rewarded
him with some varieties that were highly esteemed:--"Many varieties of
the apple were collected which had been proved to afford, in mixtures
with each other, the finest cider. A tree of each was then obtained by
grafting upon a Paradise stock, and these trees were trained to a
south wall, or if grafted on Siberian crab, to a west wall, till they
afforded blossoms, and the soil in which they were planted was made of
the most rich and favorable kind. Each blossom of this species of
fruit contains about twenty chives or males (stamens,) and generally
five pointals or females (pistils,) which spring from the center of
the cup or cavity of the blossom. The males stand in a circle just
within the bases of the petals, and are formed of slender threads,
each of which terminates in an anther. It is necessary in these
experiments that both the fruit and seed should attain as large a size
and as much perfection as possible, and therefore a few blossoms only
were suffered to remain on each tree. As soon as the blossoms were
nearly full-grown, every male in each was carefully extracted, proper
care being taken not to injure the pointals; and the blossoms, thus
prepared, were closed again, and suffered to remain till they opened
spontaneously. The blossoms of the tree which it was proposed to make
the male parent of the future variety, were accelerated by being
brought into contact with the wall, or retarded by being detached from
it, so that they were made to unfold at the required period; and a
portion of their pollen, when ready to fall from the mature anthers,
was during three or four successive mornings deposited upon the
pointals of the blossoms, which consequently afforded seeds. It is
necessary in this experiment that one variety of apple only should
bear unmutilated blossoms; for, where other varieties are in flower at
the same time, the pollen of these will often be conveyed by bees to
the prepared blossoms, and the result of the experiment will in
consequence be uncertain and unsatisfactory." * * *
In his Pomona Herefordiensis, he says:--"It is necessary to contrive
that the two trees from which you intend to raise the new kind, shall
blossom at the same time; therefore, if one is an earlier sort than
the other, it must be retarded by shading or brought into a cooler
situation, and the latest forwarded by a warm wall or a sunny
position, so as to procure the desired result."
We must distinguish between hybrids proper and crosses, as it were
between races or between what may have been erroneously designated
species, for there has been a great deal of looseness in the manner of
using these terms by some writers. A true _hybrid_[9] is produced only
when the pollen of one species has been used to fertilize the ovules
of another, and as a general rule these can only be produced between
plants which are very nearly allied, as between species of the same
genus. Even such as these, however, cannot always be hybridized, for
we have never found a mule or hybrid between the apple and pear, the
currant and gooseberry, nor between the raspberry and blackberry,
though each of these, respectively, appear to be very nearly related,
and they are all of the order _Rosaceæ_.
In hybrids there appears to be a mixture of the elements of each, and
the characters of the mule or cross will depend upon one or the other,
which it will more nearly resemble. True hybrids are mules or
infertile, and cannot be continued by seed, but must be propagated by
cuttings, or layers, or grafting. If not absolutely sterile at first,
they become so in the course of the second or third generation. This
is proved by several of our flowering plants that have been
wonderfully varied by ingenious crossing of different species. But it
has been found that the hybrid may be fertilized by pollen taken from
one of its parents, and that then the offspring assumes the characters
of that parent.[10]
Natural hybrids do not often occur, though in dioecious plants, this
seems to have been the case with willows that present such an
intricate puzzle to botanists in their classification, so that it has
become almost impossible to say what are the limits and bounds of some
of the species. Hybrids are, however, very frequently produced by art,
and particularly among our flowering plants, under the hands of
ingenious gardeners. Herbert thinks, from his observations, "that the
flowers and organs of reproduction partake of the characters of the
female parent, while the foliage and habit, or the organs of
vegetation, resemble the male."
Simply crossing different members of the same species, like the
crossing of races in animal life, is not always easily accomplished;
but we here find much less difficulty, and we do not produce a mule
progeny. In these experiments the same precautions must be taken to
avoid the interference of natural agents in the transportation of
pollen from flower to flower; but this process is now so familiar to
horticulturists, that it scarcely needs a mention. In our efforts with
the strawberry, some very curious results have occurred, and we have
learned that some of the recognized species appear under this severe
test to be well founded, as the results have been infertile. Where the
perfection of the fruit depends upon the development of the seed, this
is a very important matter to the fruit-grower; but fortunately this
is not always the case, for certain fruits swell and ripen perfectly,
though containing not a single well developed seed. It would be an
interesting study to trace out those plants which do furnish a well
developed fleshy substance or sarcocarp, without the true seeds. Such
may be found occasionally in the native persimmon, in certain grapes,
and in many apples; but in the strawberry, blackberry, and raspberry,
the berry which constitutes our desirable fruit, never swells unless
the germs have been impregnated and the seeds perfect. In the
stone-fruits the stone or pit is always developed, but the enclosed
seed is often imperfect from want of impregnation or other cause--and
yet the fleshy covering will sometimes swell and ripen.
One of the most successful experimenters in this country is Doctor
J.P. Kirtland, near Cleveland, Ohio, whose efforts at crossing certain
favorite cherries, were crowned with the most happy results, and all
are familiar with the fruits that have been derived from his crosses.
The details of his applying the pollen of one flower to the pistils of
another are familiar to all intelligent readers, and have been so
often set forth, that they need not be repeated in this case--great
care is necessary to secure the desired object, and to guard against
interference from causes that would endanger or impair the value of
the results.
Van Mons' theory was based upon certain assumptions and observations,
some of which are well founded, others are not so firmly established.
He claimed correctly that all our best fruits were artificial
products, because the essential elements for the preservation of the
species in their natural condition, are vigor of the plant and perfect
seeds for the perpetuation of the race. It has been the object of
culture to diminish the extreme vigor of the tree so as to produce
early fruitage, and at the same time to enlarge and to refine the
pulpy portion of the fruit. He claimed, as a principle, that our
plants of culture had always a tendency to run back toward the
original or wild type, when they were grown from seeds. This tendency
is admitted to exist in many cases, but it is also claimed, that when
a break is once made from the normal type, the tendency to improve may
be established. Van Mons asserted that the seeds from old trees would
be still more apt to run back toward the original type, and that "the
older the tree, the nearer will the seedlings raised from it approach
the wild state," though he says they will not quite reach it. But the
seeds from a young tree, having itself the tendency to melioration,
are more likely to produce improved sorts.
He thinks there is a limit to perfection, and that, when this is
reached, the next generation will more probably produce bad fruit than
those grown from an inferior sort, which is on the upward road of
progression. He claims that the seeds of the oldest varieties of good
fruit yield inferior kinds, whereas those taken from new varieties of
bad fruit, and reproduced for several generations, will certainly give
satisfactory results in good fruit.
He began with seeds from a young seedling tree, not grafted upon
another stock; he cared nothing for the quality of the fruit, but
preferred that the variety was showing a tendency to improvement or
_variation_. These were sowed, and from the plants produced, he
selected such as appeared to him to have evidence of improvement, (it
is supposed by their less wild appearance), and transplanted them to
stations where they could develop themselves. When they fruited, even
if indifferent, if they continued to give evidence of variation, the
first seeds were saved and planted and treated in the same way. These
came earlier into fruit than the first, and showed a greater promise.
Successive generations were thus produced to the fourth and fifth,
each came into bearing earlier than its predecessor, and produced a
greater number of good varieties, and he says that in the fifth
generation they were nearly all of great excellence. He found pears
required the longest time, five generations; while the apple was
perfected in four, and stone fruits in three.
Starting upon the theory that we must subdue the vigor of the wilding
to produce the best fruits, he cut off the tap roots when
transplanting and shortened the leaders, and crowded the plants in the
orchard or fruiting grounds, so as to stand but a few feet apart. He
urged the "regenerating in a direct line of descent as rapidly as
possible an improving variety, taking care that there be no interval
between the generations. To sow, re-sow, to sow again, to sow
perpetually, in short to do nothing but sow, is the practice to be
pursued, and which cannot be departed from; and, in short, this is the
whole secret of the art I have employed." (_Arbres Fruitiers._)
Who else would have the needed patience and perseverance to pursue
such a course? Very few, indeed--especially if they were not very
fully convinced of the correctness of the premises upon which this
theory is founded. Mr. Downing thinks that the great numbers of fine
varieties of apples that have been produced in this country, go to
sustain the Van Mons doctrine, because, as he assumes, the first
apples that were produced from seeds brought over by the early
emigrants, yielded inferior fruit which had run back toward the wild
state, and the people were forced to begin again with them, and that
they most naturally pursued this very plan, taking seeds from the
improving varieties for the next generations and so on. This may have
been so, but it is mere assumption--we have no proof, and, on the
contrary, our choice varieties have so generally been conceded to have
been chance seedlings, that there appears little evidence to support
it--on the contrary, some very fine varieties have been produced by
selecting the seeds of good sorts promiscuously, and without regarding
the age of the trees from which the fruit was taken. Mr. Downing
himself, after telling us that we have much encouragement to
experiment upon this plan of perfecting fruits, by taking seeds from
such as are not quite ripe, gathered from a seedling of promising
quality, from a healthy young tree (quite young,) on its own root, not
grafted, and that we "must avoid 1st, the seeds of old trees; 2d,
those of grafted trees; 3d, that we must have the best grounds for
good results"--still admits what we all know, that "in this country,
new varieties of rare excellence are sometimes obtained at once by
planting the seeds of old grafted varieties; thus the Lawrence
Favorite and the Columbia Plums were raised from seeds of the Green
Gage, one of the oldest European varieties."
Let us now look at an absolute experiment conducted avowedly upon the
Van Mons plan in our own country, upon the fertile soil of the State
of Illinois, and see to what results it led:--
The following facts have been elicited from correspondence with H.P.
Brayshaw, of Du Quoin, Illinois. The experiments were instituted by
his father many years ago, to test the truth of the Van Mons' theory
of the improvement of fruits by using only the first seeds.
Thirty-five years ago, in 1827, his father procured twenty-five
seedling trees from a nursery, which may be supposed to have been an
average lot, grown from promiscuous seed. These were planted, and when
they came into bearing, six of them furnished fruit that might be
called "_good_" and of these, "four were considered _fine_." One of
the six is still in cultivation, and known as the _Illinois Greening_.
Of the remainder of the trees, some of the fruits were fair, and the
rest were worthless, and have disappeared.
_Second Generation._--The first fruits of these trees were selected,
and the seeds were sown. Of the resulting crop, some furnished fruit
that was "good," but they do not appear to have merited much
attention.
_Third Generation._--From first seeds of the above, one hundred trees
were produced, some of which were good fruit, and some "even fine,"
while some were very poor, "four or five only merited attention." So
that we see a retrogression from the random seedlings, furnishing
twenty-five per cent, of good fruit, to only four or five per cent. in
the third generation, that were worthy of note.
_Fourth Generation._--A crop of the first seed was again sown,
producing a fourth generation; of these many were "good culinary
fruits," none, or very few being of the "poorest class of seedlings,"
none of them, however, were fine enough "for the dessert."
_Fifth Generation._--This crop of seedlings was destroyed by the
cut-worms, so that only one tree now remains, but has not yet fruited.
But Mr. Brayshaw appears to feel hopeful of the results, and promises
to continue the experiment.
Crops have also been sown from some of these trees, but a smaller
proportion of the seedlings thus produced were good fruits, than when
the first seeds were used--this Mr. Brayshaw considers confirmatory
evidence of the theory, though he appears to feel confidence in the
varieties already in use, most of which had almost an accidental
origin.
He thinks the result would have been more successful had the blossoms
been protected from impregnation by other trees, and recommends that
those to be experimented with should be planted at a distance from
orchards, so as to avoid this cross-breeding, and to allow of what is
called breeding in-and-in. If this were done, he feels confident that
"the seedlings would more nearly resemble the parent, and to a certain
extent would manifest the tendency to improvement, and that from the
earliest ripened fruits, some earlier varieties would be produced,
from those latest ripening, later varieties, from those that were
inferior and insipid, poor sorts would spring, and that from the very
best and most perfect fruits we might expect one in one thousand, or
one-tenth of one per cent., to be better than the parent." This
diminishes the chance for improvement to a beautifully fine point upon
which to hang our hopes of the result of many generations of seedlings
occupying more than a lifetime of experiments.
Mr. Brayshaw, citing some of the generally adopted axioms of breeders
of animals, assumes that _crosses_, as of distinct races, will not be
so likely to produce good results, as a system of breeding in-and-in,
persistently carried out. This plan he recommends, and alludes to the
quince and mulberry as suitable species to operate upon, because in
them there are fewer varieties, and therefore less liability to
cross-breeding, and a better opportunity for breeding in-and-in. He
also reminds us of the happy results which follow the careful
selection of the best specimens in garden flowers and vegetables,
combined with the rejection of all inferior plants, when we desire to
improve the character of our garden products, and he adopts the views
of certain physiologists, which, however, are questioned by other
authorities, to the effect that violent or decided crosses are always
followed by depreciation and deterioration of the offspring.
The whole communication referring to these experiments, which are
almost the only ones, so far as I know, which have been conducted in
this country to any extent, to verify or controvert the Van Mons'
theory, is very interesting, but it is easy to perceive that the
experimenter, though apparently very fair, and entirely honest, has
been fully imbued with the truth and correctness of the proposition of
Van Mons, that the first ripened seed of a natural plant was more
likely to produce an improved variety, and that this tendency to
improvement would ever increase, and be most prominent in the first
ripened seeds of successive generations grown from it.
The theory of Van Mons I shall not attempt in this place to
controvert, but will simply say that nothing which has yet come under
my observation has had a tendency to make me a convert to the avowed
views of that great Belgian Pomologist, while, on the contrary, the
rumors of his opponents, that he was really attempting to produce
crosses from some of the best fruits, as our gardeners have most
successfully done in numerous instances, in the beautiful flowers and
delicious vegetables of modern horticulture, have always impressed me
with a color of probability, and if he were not actually and
intentionally impregnating the blossoms with pollen of the better
varieties, natural causes, such as the moving currents of air, and the
ever active insects, whose special function in many instances appears
to be the conveyance of pollen, would necessarily cause an admixture,
which, in a promiscuous and crowded collection, like the "school of
Van Mons," would at least have an equal chance of producing an
improvement in some of the resulting seeds.
The whole subject of variation in species, the existence of varieties,
and also of those partial _sports_, which may perhaps be considered as
still more temporary variations from the originals, than those which
come through the seeds, is one of deep interest, well worthy of our
study, but concerning which we must confess ourselves as yet quite
ignorant, and our best botanists do not agree even as to the
_specific_ distinctions that have been set up as characters of some of
our familiar plants, for the most eminent differ with regard to the
species of some of our common trees and plants.
RUNNING OUT OF VARIETIES.
It has been a very generally received opinion among intelligent
fruit-growers, that any given variety of fruit can have but a limited
period of existence, be that longer or shorter. Reasoning from the
analogies of animal life this would appear very probable, for it is
well known that individuals of different species all have a definite
period of life, some quite brief, others quite extended, beyond which
they do not survive. But with our modern views of vegetation, though
we know that all perennial plants do eventually die and molder away to
the dust from whence they were created, and that many trees of our own
planting come to an untimely end, while we yet survive to observe
their decay, still, we can see no reason why a tree or parts of a tree
taken from it, and placed under circumstances favorable to its growth
from time to time, may not be sempiternal. Harvey has placed this
matter in a correct light, by showing that the true life and history
of a tree is in the buds, which are annual, while the tree itself is
the connecting link between them and the ground. Any portion of such a
compound existence, grafted upon another stock, or planted immediately
in the ground itself and established upon its own roots, will produce
a new tree like the first, being furnished with supplies of
nourishment it may grow indefinitely while retaining all the qualities
of the parent stock--if that be healthy and vigorous so will
this--indeed new life and vigor often seem to be imparted by a
congenial thrifty stock, and a fertile soil, so that there does not
appear to be any reason why the variety should ever run out and
disappear.
The distinguished Thomas Andrew Knight, President of the London
Horticultural Society, was one of the leading advocates of the theory
that varieties would necessarily run out and disappear as it were by
exhaustion.
In his Pomona Herefordiensis, he tells us that "those apples, which
have been long in cultivation, are on the decay. The Redstreak and
Golden Pippin can no longer be propagated with advantage. The fruit,
like the parent tree, is affected by the debilitated old age of the
variety." And in his treatise on the culture of the apple and pear, he
says: "The Moil and its successful rival, the Redstreak, with the Must
and Golden Pippin, are in the last stage of decay, and the Stire and
Foxwhelp are hastening rapidly after them." In noticing the decay of
apple trees, Pliny probably refers to particular trees, rather than
the whole of any variety, when he says that "apples become old sooner
than any other tree, and the fruit becomes smaller and is subject to
be cankered and worm-eaten, even while on the trees."--Lib. XVI, Chap.
27.
Speechly combated the views of Mr. Knight, and says: "It is much to be
regretted that this apparently visionary notion of the extinction of
certain kinds of apples should have been promulgated by authors of
respectability, since the mistake will, for a time at least, be
productive of several ill consequences."
Some of the old English varieties that were supposed to be worn out or
exhausted, appear to have taken a new lease of life in this country,
but we have not yet had a long enough experience to decide this
question. Many of the earlier native favorites of the orchard have,
for some reason, disappeared from cultivation--whether they have run
out, were originally deficient in vigor, or have merely been
superseded by more acceptable varieties, does not appear.
Mr. Phillips, in his Companion, states "that in 1819, he observed a
great quantity of the Golden Pippin in Covent Garden Market, which
were in perfect condition, and was induced to make inquiries
respecting the health of the variety, which resulted in satisfactory
replies from all quarters, that the trees were recovering from
disease, which he thought had been induced by a succession of
unpropitious seasons. He cites Mr. Ronald's opinion, that there was
then no fear of losing this variety; and Mr. Lee, who thought that the
apparent decay of some trees was owing to unfavorable seasons. Mr.
Harrison informed him that this variety was very successfully grown on
the mountains of the island of Madeira, at an elevation of 3000 feet,
and produced abundantly. Also that the variety was quite satisfactory
in many parts of England, and concludes that the Golden Pippin only
requires the most genial situation, to render it as prolific is
formerly."
It is quite probable, as Phillips suggests, that Mr. Knight had
watched the trees during unfavorable seasons which prevailed at that
period, and as he found the disease increase, he referred it to the
old age of the variety, and based his theory to that effect upon
partial data.
Mr. Knight's views, though they have taken a strong hold upon the
popular mind, have not been confirmed by physiologists. For though the
seed would appear to be the proper source whence to derive our new
plants, and certainly our new varieties of fruits, many plants have,
for an indefinite period, been propagated by layers, shoots or scions,
buds, tubers, etc., and that the variety has thus been extended much
beyond the period of the life of the parent or original seedling.
Strawberries are propagated and multiplied by the runners, potatoes by
tubers, the Tiger Lily by bulblets, some onions by proliferous bulbs,
sugarcane by planting pieces of the stalk, many grapes by horizontal
stems, and many plants by cuttings, for a very great length of time.
The grape vine has been continued in this way from the days of the
Romans. A slip taken from a willow in Mr. Knight's garden pronounced
by him to be dying from old age, was planted in the Edinburgh Botanic
Garden many years ago, and is now a vigorous tree, though the original
stock has long since gone to decay.[11]

All propagation of plants must depend upon the development of seeds or
of buds, and all will arise from the growth and extension of cells.
The seed and the bud are much more nearly related than a casual
observer would at first sight suppose. The early phylologists thought
they discovered that in the seed was enwrapped the image of the future
tree--a dissection of the seed would appear to demonstrate this. It is
composed of separate parts which are capable of being developed into
the root, stem, and appendages, but they have yet to be so developed;
the several parts that we find in the seed are merely the
representative parts. But the seed has the future of the tree within
itself, it has certain qualities of the future tree impressed upon it
in its primary organization, within the capsule of the fruit of the
parent plant, so that in a higher sense the image of the future tree
does exist within the seed. Within the bud, still more plainly and
more distinctly visible, is the future tree manifest, and we may
produce a tree from a bud as certainly as we do from a seed. Subjected
to circumstances favorable for growth, the bud, as well as the seed,
will emit roots, will form its stem, branches and appendages, and will
become a tree; differing from the product of the seed only in this,
that in the latter the resulting organism constitutes a new individual
which may vary somewhat from its parent, in the former it is only a
new development of a part of a previously existing organization. The
similarity existing between the two is exceedingly close, and is a
matter of great importance in horticultural operations. Dr. Lindley,
in the Gardener's Chronicle, says very truly, that "every bud of a
tree is an individual vegetable, and a tree, therefore, is a family or
swarm of individual plants, like the polype with its young growing out
of its sides, or like the branching cells of the coral insect."
Similar opinions, more or less modified, have been expressed by
subsequent physiologists, and are familiar to men of science in every
country and, we may add, are also universally accepted as true by all
who claim a right to express an opinion upon the subject.--Men of
science recognize the individuality of buds.--Nobody doubts the
individuality of buds.--In a gardening aspect, the individuality of
buds is the cardinal point upon which some of our most important
operations turn; such, for example, as all modes of propagation
whatever, except by seed. If this be not fully understood, there is no
possible explanation of the reasons why certain results are sure to
follow the attachment of a bud, or the insertion of a graft, or the
planting of a cutting, or the bending of a layer, or the approach of a
scion, or the setting of an eye--our six great forms of artificial
multiplication. In his Elements of Botany, the same writer says: "An
embryo is a young plant produced by the agency of the sexes, and
developed within a seed--a leaf bud is a young plant, produced without
the agency of the sexes, enclosed within the rudimentary leaves called
scales, and developed on a stem." "An embryo propagates the _species_,
leaf-buds propagate the _individual_." He shows each to be "a young
plant developing itself upwards, downwards and horizontally, into
stem, root, and medullary system."
Dr. Schleiden thus beautifully expresses his views of their
individuality: "Now the bud essentially is nothing more than a
repetition of the plant on which it is formed. The foundation of a new
plant consists equally of a stem and leaves, and the sole distinction
is that the stem becomes intimately blended at its base with the
mother plant in its growth, and has no free radical extremity like
that exhibited by a plant developed from a seed. However, this
distinction is not so great as at the first glance it appears. Every
plant of high organization possesses the power of shooting out
adventitious roots from its stem, under the favoring influences of
moisture; and very frequently, even plants that have been raised from
seed, are forced to content themselves with such adventitious roots,
since it is the nature of many plants, for instance the grasses, never
to develop their proper root, although the radicle is actually
present. We are, it is true, accustomed to look upon the matter as
though the buds must always be developed into twigs and branches, on
and in connection with the plant itself; and thus in common life, we
regard them as parts of a plant, and not as independent individuals,
which they are in fact, although they, like children who remain in
their paternal home, retain the closest connection with the plant on
which they were produced. That they are at least capable of becoming
independent plants, is shown by an experiment frequently successful
when the necessary care is taken, namely the breaking off and sowing
of the buds of our forest trees. The well-known garden operations of
grafting and budding are also examples of this, and layering only
differs from the sowing of the buds, in that the buds on the layers
are allowed to acquire a certain degree of maturity before they are
separated from the parent plant. All here depends upon the facility
with which these bud plants root as it is called, that is develop
adventitious roots, when they are brought in contact with moist earth.
* * * Nature herself very often makes use of this method to multiply
certain plants in incalculable numbers. In a few cases, the process
resembles the artificial sowing of buds, as when the plant
spontaneously throws off the perfect buds at a certain period; an
instance of this is afforded by some of our garden Lilies, which throw
off the little bulb-like buds which appear in the axils of the lower
leaves. The more common mode of proceeding is as follows: Those buds
which have been formed near the surface of the soil, grow up into
shoots provided with leaves; but the shoots are long, slender and
delicate, the leaves too are stunted into little scales; in their
axils, however, they develop strong buds, which either in the same or
in the following year take root, and the slender shoot connecting them
with the parent plant, dying and decaying, they become free
independent plants. In this manner the strawberry soon covers a
neglected garden."[12]
Upon the development of a cell in any living tissue, and its power of
reproducing other cells, and upon its function of communicating by
endosmosis and exosmosis with other like cells, depend all our success
in propagating vegetables, whether from seeds or buds, and parts
containing these. We must study the circumstances that favor the
development of cells, if we would be successful in propagating plants.
Each bud being considered an individual, and capable, under favorable
circumstances, of taking on a separate existence, we can multiply any
individual variety indefinitely, and be sure of having the same
qualities of foliage and fruit that we admire in the original, and
that we may desire to propagate. This applies equally to a group of
buds, as in cuttings, grafts and layers, etc.; but, more wonderful
still, there are cells capable of developing buds where none existed
before, and even in tissues or parts of a plant where we do not
usually find buds--hence we have a mode of propagation of many woody
plants, by root cuttings, and by leaves, and even parts of leaves.
PROPAGATION BY CUTTINGS.--Many fruits are multiplied by this means.
Healthy shoots of the previous year's growth are usually selected and
taken when the parent is in a dormant state, or still better, when it
is approaching this condition. Sometimes a small portion of the
previous year's growth is left with the cutting, making a sort of
_heel_; when this is not to be had, or not preferred, the slip is to
be prepared for planting by cutting it smoothly just below a bud, as
this seems to be the most favorable point in many plants for the
emission of roots. Some plants will throw out radicles at any point
indifferently along the internodes or merithallus. The preference for
heel-cuttings depends upon the fact, that near the base of the annual
shoot there are always a great number of buds, many of which, however,
being imperfectly developed, are inconspicuous, but though dormant,
they seem to favor the emission of rootlets. Cuttings may be made to
grow if taken at any period of their development, but when green and
soft, they require particular conditions of heat and moisture in the
soil, and atmosphere, that are only under the control of the
professional gardener. They are usually taken in the dormant state,
because they are then susceptible of being made to grow under the
ordinary conditions of out-door gardening. If cut early in the season,
on the approach of autumn, after the wood-growth has been perfected,
they may be planted at once with good prospect of success, or they may
be put into the soil, out of doors, in the cellar, or in a cold frame
or pit, and a very important step in the progress of their growth will
commence at once. The leafless sticks are not dead, and whenever the
temperature will admit of the quiet interchange of fluids among their
cells, this curious function will go on, and will be accompanied by
the development or generation of new cells that soon cover the cut
surfaces, constituting what the gardeners call the _callus_. This is
the first step toward growth, and it most readily occurs when the
earth is warmer than the air; hence the value of fall planting,
whether of trees or of cuttings, if done before the earth has been
chilled, and hence also, the importance of bottom heat in artificial
propagation. If on the contrary the air be warm and the ground cold,
the buds are often stimulated to burst forth, before the rootlets can
have started. The expanding foliage which so delights the tyro in
propagation, offers an extended surface for evaporation, the contained
juices of the cutting itself are soon exhausted, no adequate supply is
furnished, and the hopeful plant soon withers, or damps off, and
dies.[13] The cutting, like the seed, must have "first the root, then
the blade." The length of time that is allowed for cuttings to prepare
for rooting, if they are designed for spring planting, should be as
great as possible, and the circumstances under which they are kept
should be such as to favor the development of the cells, so that roots
may form freely with the breaking of the buds, if not before.
Root-cuttings should be made in the spring, just before the usual
period of the bursting of the buds in the plant to be propagated. The
tendency to develop buds appears to be then most active. Gentle
bottom heat, though not essential, is still very desirable, and will
conduce to the success of the operation. Some plants are best
propagated by this means, and those too, which never naturally produce
suckers, may often be successfully grown by sections of the roots. All
plants do not equally admit of propagation by division as cuttings,
some woody tissues refusing to emit roots under almost any
circumstances.
Nobody thinks of propagating the stone fruits, such as the cherry,
plum, peach, or apricot, by attempting to plant cuttings, and yet some
of these will emit roots very freely, as we may often observe when the
shoots or trimmings are used as supports for plants in the
green-house. The plum tree is exceedingly apt to form new roots when
planted too deeply, and upon this fact depends the success or failure
of the finer varieties when worked upon certain varieties of the wild
stock. If the young trees are earthed up in the nursery, and set
rather deeply in the orchard, they will soon establish a good set of
roots of their own, emitted above the junction of the scion and stock,
which is very preferable to the imperfect union and consequent
enlargement that often results from using uncongenial stocks. The
raspberry and blackberry do not grow so well from cuttings of the
wood, which is always biennial in this genus, as they do from
root-cuttings.
In some parts of the country, peaches are mainly produced, or the
favorite varieties are multiplied, by planting the sprouts that come
from the base of the trunk of the trees; these have little or no roots
when taken off with the mattock, but they soon establish themselves
and make good trees, bearing fruit like their parents, in soils and
climate that are well adapted to this fruit.
Refined and scientific horticulture has been extensively applied to
the multiplication of the grape, which is now produced in immense
numbers, from single eyes, or buds. Formerly our vineyards were formed
by planting long cuttings at once in the field in the stations to be
occupied by the vines, or by setting them first in a nursery, whence
they were transplanted to the vineyard, when one or two years old.
Only the most refractory kinds, which would not grow readily in the
field, or such as were yet rare, were propagated from cuttings, by
using the single eye and artificial bottom heat. Now, however, the
appliances of our propagators are called upon for the production of
grape-vines by the million, and they find it advisable to multiply all
the varieties in this manner. The propagation of the grape by using
single eyes affords the most beautiful illustration of the subject of
the individuality of buds, and though denounced by some as an
unnatural, steam-forcing process, it is really an evidence of the
advance of horticulture, since every step is supported by a
philosophical reason, and the whole process, to be successful, is
dependent upon the application to practice of well established
scientific truths.
[Illustration: Fig. 1.--FRENCH AND COMMON MODES OF SETTING
CUTTINGS.]
It has already been stated that the first effect of cell-growth upon a
cutting, is the production of a callus. This callus may form upon any
cut surface, or even where the bark has been abraded. It is the first
effort of nature to repair an injury by the reproduction of new parts;
it is most generally found at the base of the cutting, but under
favorable circumstances, it will be seen also at the upper end of the
shoot if this has been placed in contact with the earth. Cuttings will
sometimes be set up-side down, when we find the callus upon the
smaller end, and roots will be emitted from that portion whence we
should have expected to see the branches issue. Upon this fact, and to
multiply the chances of living, has been based the French method, as
it is called, or that of inserting both ends of the cuttings. The
common mode, (fig. 1), is to set the cuttings in a slanting direction
in the ground, so placed that the upper eye or bud only shall reach
the surface. Formerly there was a preference for long cuttings, and
these were often made eighteen inches or more in length. The practice
with most of our cultivators has been modified in this particular, and
they have reduced the length of the slips to six and eight inches, so
as to have in grape wood about three or four eyes. Some have gone
still further, and use but two, even for out-door planting of the
grape, and some have been very successful when using but a single
joint. The Germans have advocated longer cuttings, upon the theory
that there was a retroaction in the pith of the internodes and in all
the buds of the cutting, upon the lower point, enabling it to push
roots more strongly from a long than from a short cutting. This
theory has for its support the fact, that there is in such a cutting a
larger amount of organizable matter to be developed into the new parts
to be produced, and certainly, if neglected, short cuttings will be
very apt to suffer from drought, but in practice, it is found that the
short cutting plants have better roots, which are near the surface,
and even those plants, grown from single eyes, are better burnished
than long cuttings produced upon the old plan, which placed the roots
deep in the soil.
[Illustration: Fig. 2.--ONE-EYE CUTTINGS OF THE GRAPE.]
There are various methods of preparing the single-eye cuttings, some
of which are represented in fig. 2.
Among our cultivated fruits there is but a limited number that need to
be propagated by cuttings, though, where it becomes necessary, many of
them may be grown in this manner, to which procedure there are no
serious objections, though there are some of a theoretical nature. The
currant and the gooseberry are increased almost exclusively from
cuttings, they strike root very readily, and are multiplied to any
extent; their seeds are sown only to produce new varieties. The grape
is propagated very extensively by cuttings; the slips are often
planted in the field and in the stations where the vines are wanted
for the vineyard; but some varieties are so unsatisfactory in their
results, that other more elaborate and scientific means must be taken
for their propagation. Among the larger fruits, those constituting our
trees, we do not depend upon cuttings, except in the quince, which is
not only grown for its fruit, but is also largely produced as a stock
for the dwarfed pear, and is extensively propagated from cuttings. The
Paradise apple, a dwarf stock, is multiplied in the same way. Pears
and apples may be grown from cuttings, but this plan is not pursued
with them to any extent. Those that are root-grafted, or budded very
low, especially the pear on quince stocks, will often produce roots if
favorably situated, but there is a great difference in varieties, some
rarely produce a root, while others are very prone to do it; from
observations of this fact, a new phase of dwarf-pear culture has been
inaugurated.
SUCKERS.--One of the simplest methods of multiplying varieties
consists of increasing and encouraging the suckers thrown up by the
roots; these are separated and set out for trees. We have been told by
some physiologists that there was an absolute difference in structure
between the root and the stem, that they could not be substituted the
one for the other; and yet the oft quoted marvel of the tree which was
planted upside down, and which produced flowers and leaves from its
roots, while its branches emitted fibres, and became true roots, is
familiar to every one. Here, as in other cases, our teachers have led
us into error by attempting to trace analogy with animal anatomy and
physiology, and by directing our attention to the circulation of
plants, as though they, like the higher animals, possessed true
arterial and venous currents of circulating fluids. The cell
circulation is quite a different affair, and can be conducted in
either direction, as every gardener knows who has ever layered a
plant, or set a cutting upside down. So with the roots--they are but
downward extensions of the stem; under ordinary circumstances they
have no need for buds, but these may be, and often are developed, when
the necessity for their presence arises. Buds do exist on roots,
especially upon those that are horizontal and near the surface, and
from them freely spring suckers, which are as much parts of the parent
tree as its branches, and may be planted with entire certainty of
obtaining the same fruit, just as the twigs when used as cuttings, or
scions, when grafted, will produce similar results.
Whole orchards are planted, in some sections of the country, with the
suckers from old trees; apples, pears, plums, and even peaches, as
well as raspberries and blackberries, are multiplied in this primitive
way. There are some varieties of apples that have been so propagated
for half a century, and extended for hundreds of miles in this way by
the pioneer emigrants, without ever having been grafted, until their
merits have at length accidentally become known to the Pomological
Societies and nurserymen, when the propagation of them by grafting
soon supercedes the more primitive method. Sucker trees are objected
to upon the grounds that they are not healthy and thrifty, that they
do not have good roots. Inherent disease of the parent tree will of
course be transmitted with its other peculiarities, but I cannot
imagine that this would be any more likely to occur in a sucker than
in a layer, or cutting, or graft. As to the roots, they may be more
developed upon one side than another in the young tree, and this state
of things may continue in the adult; we often observe the same
condition in the stumps of the monarchs of our forests, which were
never suspected in the day of their glory and pride of having such a
fault. But such a condition of roots is not essential to the sucker,
which may be made to have as fine a system of lateral roots, and as
evenly and regularly distributed as those of a seedling tree. Another
objection to this mode of propagation has much truth and some force;
that is, that suckers are very apt to produce suckers again. This is
particularly the case with the Morello cherry, which is a favorite
stock, upon which to work many of the choice varieties. As an offset
to this it may be urged, that the small fibrous roots, which are
supposed to conduce to early fruitfulness, abound in trees propagated
by this means, and this may be the reason why the fruit trees that
have been thus multiplied, are very generally remarkable for their
precocious fruiting. Some of the apples that have been long increased
in this manner, bear so early, and so bountifully, as to prevent them
from ever forming very large trees; they often have a stunted
appearance, and not infrequently present a peculiar inequality upon
the bark, portions being swollen or enlarged like warts--from which,
in some cases, it is easy to force out shoots or sprouts; they are
indeed true gemmules like those of the old olive trees, and like them
might be used for the propagation of the variety; a similar condition,
no doubt, exists in the roots, whence the tendency to sucker. The
common Morello cherry; the Damson; the Chickasas, and other varieties
of plum; the blackberry, and many raspberries, are multiplied almost
exclusively in a similar manner.
LAYERS are portions of the branches of a plant that have been induced
to throw out roots, and which can thus set up an independent existence
if removed from the parent tree. This mode of propagation is a very
natural one, and was probably an accidental discovery. In its traits,
it is the reverse of the mode we have just been considering. Here the
branch emits roots, instead of the root emitting branches, as in the
case of the sucker. Layering is frequently resorted to as a mode of
propagation, it is very simple, easily performed, and, with some
species, very certain in its results. Some plants will root readily if
merely placed in contact with the ground, or very slightly covered
with soil; others require some artificial interference, such as
ringing, or twisting, or slitting. The raspberry, known as the _Rubus
occidentalis_ or Black-cap, belongs to the first class, and it even
places itself in contact with the soil by recurving its branches so as
to bring the tips to the earth, where they strike root, and make new
plants. The grape comes under the second category, needing only a
little assistance, and it is multiplied to a considerable extent in
this manner. In the spring, the vines are laid out in a little shallow
trench, and pegged down closely; as the buds burst, they throw up
shoots which are trained vertically by tying them to sticks, and as
soon as these shoots have acquired a certain degree of maturity and
firmness, the mellow earth is drawn up to them and they emit a
beautiful system of roots, and by the fall they form very fine plants,
(fig. 3). The layered branch is then taken up and the several plants
are separated, when it will be found that the best roots are chiefly
from the lower joints of the new wood, rather than from the old canes
that were laid down in the spring.
[Illustration: Fig. 3.--PROPAGATING THE GRAPE BY LAYERING.]
[Illustration: Fig. 4.--LAYERING THE QUINCE.]
[Illustration: Fig. 5.--STOOL LAYERING THE QUINCE.]
Quinces are considerably increased by a sort of layering, as the twigs
emit roots very freely; they are often bent down, slightly twisted, or
not, as the case may be, and covered with mellow soil, when they
readily emit roots, become firmly established, and may be set out by
themselves, (fig. 4). There is, however, another method of layering,
much practiced in the multiplication of the quince; that called
propagation by stools. The plants are set in open rows, four feet
wide, and three or four feet apart in the rows; they should be so
planted as to stand below the general surface, that is in trenches.
When cut off at the ground in the spring, they throw up a great number
of shoots, and the earth is gradually worked up to these to encourage
their rooting, (see figure 5), which is often sufficient for removal
the first season; if, on inspection, the roots are not found to be
sufficiently large or abundant, the earthing is continued until the
autumn of the next year, when they are removed, the stools trimmed of
their lower roots, and reset in new trenches. The plants, thus raised
from stools, are cut back severely, and are then ready to set out in
nursery rows for budding. With the quince, cultivated in this manner,
nothing is required but to accumulate the mellow earth about the
shoots; but in many plants it is necessary to notch the wood by
splitting, or cutting it for an inch or two, (as in fig. 6), making a
tongue that separates from the lower portion of the shoot, and from
which the roots are emitted. This slit should be commenced just below
a bud, and the knife is drawn upward, cutting halfway through the
wood. If commenced at one side instead of at the depending portion,
the tongue is more sure to be separated from the stock, to which it
might otherwise reunite. To insure rooting, some persons insert a
little stick or chip between the separated portions, to prevent a
re-union of the parts. The shoot, after being notched, is fastened
down, and fine soil or compost is brought about it to encourage the
development of roots. Few of the hard wooded fruit trees have been
extensively propagated by means of layers; they might be so produced,
but it has not been found profitable nor necessary.
[Illustration: Fig. 6.--MANNER OF CUTTING AND PEGGING DOWN A
LAYER.]
A very common opinion prevails that layering exhausts the mother
plant, or vine, which is used in this mode of propagating. If properly
conducted, there is no reason why this should be; but if the whole top
of any plant is bent down and made to take root, and to form
independent roots, there can be little or no return from the branches
to the original stock to strengthen it. A certain amount of healthy
growing wood should always be left in its natural position, and no
danger to the plant need be apprehended.
The wood growth of the strawberry, when allowed to take its natural
bent, is directed into the stolons or runners, which form natural
layers. Their production detracts from the central wood-growth of the
plant, and exhausts its strength to such a degree, that it often dies,
whereas, by a constant removal of the runners, as fast as they appear,
we practice a sort of summer pruning or pinching, which results in the
production of a large branching stool, with many points or centers for
the production of foliage and flowers, and thus insure the greatest
abundance of fruit. The strawberry, like one species of the raspberry,
and many other of our native plants, offers illustrations of natural
layering.
SEEDS.--The most common as well as the most natural mode of
multiplying the individual plants of most of our fruit trees, is by
sowing the seed; from this source we procure stocks upon which are
worked, by budding or grafting, the several varieties we may desire to
propagate. As an illustration of this process, I propose to speak of
apple seedlings.
The almost universal means of increasing the number of apple trees, is
by sowing the seed. This is generally selected and separated from the
fresh pomace left on the press in cider-making. The old and slow
process of hand-washing has given way, in this age of labor-saving
machinery, to more economical methods. The most approved apparatus is
constructed upon the principle of separating the seeds from the pulp
by means of their greater specific gravity; it is, indeed, much like a
gold washer, being a series of boxes or troughs through which a
current of water is made to flow; this carries the lighter portions
away from the seeds, the contents of the boxes being agitated from
time to time. At the close of the process, the clean seed is found in
the bottoms of the boxes, whence it is removed and carefully dried, by
putting it in an airy place, and stirring it frequently to prevent
mildew and fermentation. Well prepared seed is plump and bright, and
should feel cold to the hand. When the pips are broken, they should be
white and clear within; but the best test of their quality, is to
sprout a portion, and count the plants produced by a given number of
seeds.
SOWING.--The seeds may be put into the ground, either in the fall, or
spring. The soil having been well prepared, and deeply pulverized, is
thrown up in beds a few feet wide, and the seed sown in close drills
across; or without the beds, it may be sown in broad drills, by hand,
or with a machine, the rows at such a distance as to allow of culture
by horse-power. It is desirable, in either case, to get an early start
and a good stand; the weeds must be kept under from the very first,
and not allowed to have the mastery for a single day. Thorough culture
during the season, upon a deeply tilled soil, of such a character as
to retain moisture, will be found highly advantageous in the
production of this crop, and will insure immunity from leaf-blight and
other adversities. Some recommend sprouting the seed a little before
planting. If it have been kept during the winter mixed with its bulk
of sand, which is a good plan, the whole may be subjected to a gentle
heat as in a hot-bed, for a few days, just before planting. During
this time the mass must be stirred and turned every day, to prevent
fermentation and to secure an even start. Whenever the germ makes its
appearance at the points of the seeds, which is called _pipping_, the
sowing must begin, and should be done as quickly as possible; the
covering is to be slight, and the earth should be friable and not
disposed to bake. The depth at which the apple seed is to be covered
will depend upon the present and prospective state of the weather,
lighter if moist, heavier if dry, for a continued drouth might be
fatal to sprouted seed, if it were planted too near the surface; but
when the weather is not dry, it is advised that the shallower the seed
is sown, the better. The objection has been made to sprouting, that if
the process have advanced too far, the seedlings will be apt to have a
crook at or near the collar, instead of the straight fusiform
appearance they should possess when presented to the grafter.
These seedlings furnish the stocks upon which to work the finer
varieties of the apple. They are taken up in the autumn with their
long clean roots, which are often longer than their tops, the leaves
are stripped off, and they are assorted; the larger are packed away in
earth or saw-dust in the grafting department, or heeled-in out of
doors, and covered in such a way as to be accessible at any time they
may be needed during the winter. The smaller stocks are heeled-in for
spring planting in nursery rows for budding, or they may be left in
the original rows for another year's growth as seedlings. If the
plants have been well grown and not too thick, so that the majority
are of sufficient size, it will be better to take them all up at once
and assort them as just indicated, otherwise the largest only may be
drawn separately when the ground is soft with autumnal rains, leaving
the smaller seedlings for another year's growth. In assorting and
selling the stocks, nurserymen make about three classes. The very
largest, as thick as a lead-pencil, are called extra, or two-year
old, and command a higher price. The next size, called 1st class
stocks, are large enough for co-aptation to the average scions, and
long enough to make two cuts each for grafting; and those that fall
below this requisition are considered second class, and are either
thrown aside or set out for budding, and for stock or collar-grafting
in the rows.

Grafting is but a modification of propagation by cuttings. The scion
is a cutting of the variety we wish to propagate, which, instead of
being committed to the ground to emit its own roots, is placed in
contact with tissues of a nature similar to its own, through which it
is to form a connection with the roots and the soil. The success of
the operation depends upon the formative cell in this instance also,
as in the cutting; new cells are formed upon the cut surface, and the
intercommunication takes place through them. Hence we have anatomical
limits to grafting; there are physiological bounds beyond which we
cannot pass, in our combinations of scion and stock. Our success is in
the direct ratio of the affinity that exists between them; thus apple
grows best on apple, and even among these we find the _closest union_
and the best results, where there is a similarity between the style of
growth, and probably in the character of the cells.
We say, as a general rule, that stone fruits must be grafted upon
stone fruits, those bearing seeds, upon seed fruit; but there are
limits even here which confine us upon one hand, and give us more
latitude upon the other. Thus the cherry may be worked upon the wild
cherry (_Prunus Virginiana_) but it forms a very poor union; the pear
will grow upon the thorn, which has a very different seed, but the
union is very imperfect and the tree is short-lived; the apple would
appear to be much nearer of kin, since it belongs to the same genus,
but though the pear will grow vigorously upon this stock, it is no
more permanent than upon the thorn: either of them will answer when
grafted low, or in the root, to start the cutting, as the scion may
then be considered, and to sustain it until it shall have supplied
itself with roots. In top-grafting the pear upon a tree of either
species, it is found essential to success, and it conduces to the
greater durability of the tree, for some branches of the original
stock to be left intact to secure the circulation of the trunk, as the
union of the dissimilar cells is so imperfect that it does not furnish
sufficient vent for the sap. In the case of the cherry we find that
the varieties appear to have a greater affinity for those of their
own race; thus the Dukes and Morellos do well when grafted upon the
Morello stocks, whereas the Hearts and Bigarreau sorts do not make a
good union upon these stocks, but prefer the Mazzard, which has a
freer growth more like their own. Most varieties will do well upon the
Mahaleb stock, which is used as a means of dwarfing this fruit, though
not a dwarf. Upon the wild cherry, which belongs to quite a different
section of the genus, the cultivated varieties will grow, but they
form a very imperfect union.
The peach may be worked upon the plum stock, and is claimed to be
somewhat dwarfed by it, and to produce superior fruit. This stock is
more congenial to the apricot, which is frequently propagated upon it.
Both plums and apricots may be worked upon the peach stock, and they
will grow very vigorously, as they will upon the wild plum, but they
soon over-grow, and are very apt to break off. When either of these
species is used as a stock for the plum or apricot, they should be
considered merely as a nursing mother, like the apple or thorn to the
pear, which may be wanted to help the cutting until it shall be
prepared to stand alone, and feed itself from its own roots. In other
words, they should be grafted, _not budded_, into these uncongenial
stocks, and the operation should be performed in the collar or below
it, in the root, so that the growing scion may be earthed up, and
encouraged to furnish itself with a good system of roots of its own.
The success will then depend upon the ability of the scion to emit
roots freely.
We must never forget that in grafting, we are confined to very narrow
limits. Our scion must be of a similar nature with the stock, each
must have cells of a similar character, capable of transmitting their
nutritious fluids from one to the other. We must recollect likewise,
that the parts must be so co-apted that the cells of wood growth shall
be brought into as close connection as possible, in both scion and
stock; these cells are found in the layer, called the cambium, which
is between the wood and the bark. The crude sap from below will often
pass from cell to cell, when the elaborated sap of the cells in the
scion is wholly unfitted for the formation of wood cells in the stock
below it; of course the union in such a case must be very imperfect,
and the product of such a grafting will be subject to accident, and
will be short-lived, though the result in fruit, while the union
continues, may be very precocious, abundant, and of superior flavor.
Natural grafting may often be observed by the student of nature when
wandering among his favorites of the sylvan shades. There can be no
doubt that the first hint was thus communicated to the early
gardeners. In nature we always find the grafting to be inarching, or
grafting by approach; two limbs or even two trees approximating
closely, have abraded one another, and have afterward united their
tissues most firmly together. This is generally a union of two trees
of the same variety or species; but such is not always the case;
sometimes trees of very dissimilar natures unite in this manner, but
when we examine them we find only a dove-tailing, only a mechanical
union, but no vital action subsists between them. The ancients give us
some fancy sketches of the unions by grafting of very dissimilar
trees, and some moderns who have no higher claim to poetry than their
romancing, tell us that we may graft the peach upon the Willow and
Buttonwood, and form other equally impossible unions.
The different methods of performing the operation of grafting vary
with the character and size, and condition of the stocks to be worked;
thus we have splice grafting, whip, cleft, saddle, and side grafting
with modifications, and also grafting by approach, which is generally
called inarching--though sometimes also practiced where we desire to
renew the roots of a tree that are unhealthy, or to restore those that
have been removed by accident or by the erosion of some rodent
animals.
[Illustration: Fig. 7.]
SPLICE GRAFTING is the simplest process, and is applicable only where
the size of the stock and of the scion correspond pretty nearly; the
two are cut with a sloping curve, each of which being made at the same
angle, will coincide with the other when they are applied together, as
represented in the engraving, fig. 7.
[Illustration: Fig. 8.--WHIP GRAFTING.]
WHIP GRAFTING is a modification of the above. Each portion is cut in a
sloping manner as in the splice grafting, but each is also split with
a thin-bladed knife, as represented in fig. 8. The object in this is
to give a firmer union to the two portions, and also to present a more
extended surface for the effusion of the new cell tissue that is to
form the bond of union in cementing them together. In both these
methods, but especially in the first, the parts must be held together
in co-aptation by some kind of bandage; this is generally composed of
grafting wax, spread upon cloth or paper, or even, as now extensively
practiced, upon fine thread. Cotton yarn _No_. 3 is drawn through
melted grafting wax, and as it cools, it is wound upon a reel at the
other side of the room, whence it is drawn as wanted by the grafter or
tyer. Tying or wrapping is always a good precaution, and when the
splice or cleft graft is not very close, it becomes necessary; but
thousands of grafts will unite equally well where the parts are
covered with earth, without any such appliance.

[Illustration: Fig. 10.--CLEFT GRAFTING WITH BOTH SCIONS
INCLINED INWARD.]
CLEFT GRAFTING is generally done when the stock is larger than the
scion, and also where the operation is performed at a point above the
ground. The stock is split downward, after having been cut off at the
point where the grafting is to be done. The knife should be sharp, and
the bark should be cut through first, to avoid its being torn, and so
that the sides of the cleft shall be smooth. A wedge is inserted to
keep the cleft open for the insertion of the scion, which is cut on
each side like a fine wedge; but the two planes not being parallel,
the bark will be left on one side to the very point of the wedge,
while on the other it will be removed a part of the way, making a
feather edge, _A_, fig. 9. The object of this is to have the pressure
of the cleft greatest upon the outer side, where the union is to be
effected. It is well to have a bud on the strip of bark left between
the two cuts used in forming the graft, this should be near the top of
the cleft. One or two grafts may be inserted into a cleft, or more
clefts may be made, in large stocks, or in re-grafting the large limbs
of an old tree, but usually one is sufficient to leave growing; and in
the young tree, only one should ever be allowed to remain. When the
scion is nicely set into the cleft, so that the inner bark of the
stock and graft shall coincide, or rather cross a very little, (see
fig. 10,) the wedge, whether of hard wood, or of iron, should be
gently withdrawn, and then the elasticity of the stock will hold the
scion firmly to its place; this pressure should not be too severe. In
this kind of grafting, if the pressure be sufficiently firm, and if
the operation have been performed below the surface of the ground, it
may not be necessary to make any other application than to press the
moist earth about the parts, and cover all but the top of the graft
with soil, and place a stick to indicate the plant and protect it from
injury. If, on the contrary, the pressure of the cleft be not
sufficient to hold the scion firmly, as in small stocks, the graft
must be tied. For this a piece of bass matting, or cotton twine, may
be used; and if the operation has been performed above ground, the
whole must be covered with grafting wax, applied, either hot with a
brush, or cold, after having been worked with the hands, or by
wrapping with strips of muslin or paper previously spread with the
wax. In old times grafting clay was used, and applied with the hands
as a lump around the junction; but this disagreeable and clumsy
appliance has given way to more elegant and convenient arrangements.
[Illustration: Fig. 11--SIDE GRAFTING.]
[Illustration: Fig. 12--SIDE GRAFTING--THE STOCK NOT CUT BACK.]
[Illustration: Fig. 13.--TWO FORMS OF SIDE GRAFTING.--_A_, _B_,
THE SCION AND STOCK FOR THE RICHARD SIDE GRAFT. _C_, STOCK FOR
THE GIRARDIN SIDE GRAFT. _D_, SCION, AND _E_, FRUIT BUD FOR THE
SAME.]
SIDE GRAFTING is performed in two ways. In one it is a modification of
cleft grafting in which there is no cleft, but the bark is started
from the wood, and the scion, cut as shown in figure 11, is pressed
down between the wood and bark. This can only be done late in the
spring, after the sap has begun to flow in the stock, so that the bark
will run; it is indeed more like budding than grafting. The other
modification is done without cutting off the stock. The knife is
applied to the side of a stock of medium size, and a cut is made
downward and extending to one-third the diameter, fig. 12; the scion
is cut as for cleft grafting, and inserted so as to have the parts
well co-apted, and then secured as usual. This plan is useful where
there is danger of too free a flow of sap from the roots. Two other
kinds of side graft are shown in fig. 13. The left-hand figures show
the Richard side graft, in which an arched branch, _A_, is used. This
is inserted under the bark of the stock, _B_; above the graft an
incision is made in the stock down to the wood, to arrest the flow of
sap. After the insertion, the wound is covered with grafting wax. The
Girardin side graft is illustrated at the three right-hand figures. A
fruit bud, _E_, or a graft with a terminal fruit bud, _D_, is inserted
under the bark of the stock, _C_, in August, or whenever suitable buds
can be obtained and the bark will run. The wound is tied and covered
with wax, as before. The object of this grafting is to secure
immediate fruitage. Another kind of side grafting consists in plunging
a dirk-shaped knife directly through the tree, inclining the point
downward, into this opening the graft is inserted; the object being to
establish a limb on a naked portion of the trunk.
[Illustration: Fig. 14.--SADDLE GRAFTING.]
SADDLE GRAFTING is used only with stocks of small size; it is
performed by making a double slope upon the stock, and by opening a
corresponding space in the graft, by cutting two slopes in the scion,
from below upwards, so that they shall meet in the centre, as seen in
_fig._ 14. Some merely split the scion.
GRAFTING BY APPROACH, or as it is generally termed, _inarching_, is
often practiced where there is difficulty in making the scion unite
with the stock; it is not often needed in the culture of our orchard
fruits, but may be here described. The stock upon which we wish to
graft the scion, must be planted near the variety or species to be
increased. A small twig of the latter, which can be brought close to
the stock, is selected for the operation; a slice of bark and wood is
then removed from the twig, and another of equal size from the stock,
so managed, that these cut surfaces can be brought together and
secured in that position until they have united, after which the twig,
that has been used as a scion, is cut from its parent tree, and the
top of the stock is carefully reduced until the scion has sufficiently
developed itself to act as the top of the ingrafted tree, which may
afterward be transplanted to its proper station.
A modification of this grafting by approach, is, however, sometimes of
great service, where we have a valuable tree that has suffered from
disease in the roots, or from injury to them. It consists in planting
some thrifty young stocks, with good roots, about the base of the
tree, after having prepared the ground by thorough digging, and by the
addition of good soil if necessary. These stocks are then inserted
upwards into the healthy portion of the trunk, by the process of side
grafting reversed or inverted, or by the usual method of inarching.
RING GRAFTING OR BARK GRAFTING is not much used, and in small stocks
it is rather a kind of budding, for then a ring of bark is removed at
the proper season of year, generally about midsummer, and it is
replaced by a similar ring of bark from a shoot of the same size,
taken from a tree of the variety to be propagated; this ring of bark
must be furnished with a healthy bud. This method has little to
recommend it, and can only be applied when both the stock and the
scion are in a growing condition, so that the bark will run freely;
care also must be exercised to avoid injuring the eye of the bud, in
peeling off the ring. A modification of bark grafting may be applied
with great advantage, however, to an old tree, that has met with an
injury to a portion of its bark. The injured part should be pared
smoothly to the sound bark and wood. This may be done with a sloping
cut, or the edge may be made abrupt and square with a chisel and
mallet; a piece of fresh wood and bark is then to be cut from a
healthy tree and fitted precisely to the fresh wound, and secured in
its place with bandages, and grafting clay or wax is then applied,
thus making what the surgeons would call a sort of taliacotian
operation. Instead of a single piece of wood and bark, a number of
young shoots may be used to make the communication complete; these are
set close together and secured in the usual manner; see fig. 15.
[Illustration: Fig. 15.--BARK GRAFTING, TO REPAIR AN INJURED
TREE.]
RE-GRAFTING OLD ORCHARDS.--Old orchards of inferior fruit may be
entirely re-made and re-formed by grafting the limbs with such
varieties as we may desire. A new life is by this process often
infused into the trees, which is due to the very severe pruning which
the trees then receive; they are consequently soon covered with a
vigorous growth of young healthy wood, which replaces the decrepid and
often decaying spray that accumulates in an old orchard, and the fruit
produced for several years by the new growth is not only more
valuable in kind, according to the judgment used in the selection of
grafts, but it is more fair, smooth and healthy, and of better size
than that which was previously furnished by the trees. Certain
varieties are brought at once into bearing when thus top-grafted,
which would have been long in developing their fruitful condition if
planted as nursery trees. Others are always better and finer when so
worked, than on young trees. Some of the finest specimens of the
Northern Spy apple, exhibited at the fairs, have been produced by
grafts inserted into the terminal branches of old bearing trees. There
is a theory held by some orchardists, that the further the junction of
the graft with the stock is removed from the root, the better will be
the fruit. This, however, is not well supported, and the circumstance,
when observed, is probably dependent upon other causes.
In renewing an old orchard by grafting its head, it will not be a good
plan to attempt the whole tree at once; the pruning would be too
severe, and would be followed by a profusion of succulent shoots
breaking out from the large branches, such as are called
water-sprouts. Those who have practiced most, prefer at first, to
remove about one-third of the limbs for grafting, and those should be
selected at the top of the tree. The new growth thus has an open field
for its development, and the lower limbs will be invigorated, while
they tend also to preserve the equilibrium of the tree in a double
sense, physically and physiologically. The next year another third of
the limbs may be grafted, and the remainder the year following, as
practiced by Mr. Geo. Olmstead, of Connecticut, who, on the sixth
year from the first grafting, harvested 28-½ bushels of choice apples
from a single tree that was 75 years old, and which before only
produced inferior fruit. J.J. Thomas recommends, "to give a
well-shaped head to such newly formed trees, and to prevent the
branches from shooting upward in a close body near the centre of the
tree; that the old horizontal boughs should be allowed to extend to a
distance in each direction, while the upright ones should be lopped;"
see fig. 16. The same writer also advises, "instead of cutting off
large branches and grafting them at once, it is better to prune the
top in part, which will cause an emission of vigorous shoots. These
are then budded, or grafted. * * * And as the grafts gradually extend
by growth, the remainder of the top may, by successive excisions, be
entirely removed."
[Illustration: Fig. 16.--RENEWAL OF THE TOP OF AN OLD TREE.]
GRAFTING IN THE NURSERY is either done at or near the collar of the
stock, or it is performed in-doors upon the roots or sections of
roots of young stocks. The latter may be first described, as it
constitutes the most extensive means of multiplying fruit trees. It is
a sort of machinery, with division of labor, and appliances, that
enable the operators to turn out immense numbers. Machinery has indeed
been applied to the business; we have grafting apparatus to facilitate
the work. The Minkler machine consists of a frame or gauge which
regulates the angle of the slope, which is cut with a broad chisel
that reduces the roots and scions to a condition for putting them
together; by its use an immense number of grafts can be cut, and
another hand binds them together with the waxed thread, without any
tie. Mr. Robey's machine consists of a complicated shears to cut the
slope and tongue at one operation, preparing the pieces for whip
grafting. Mr. S.S. Jackson, of Cincinnati, has also invented an
apparatus for this purpose, which proves to be very useful.
ROOT GRAFTING.--The methods of performing the operation vary somewhat,
but all agree in the object to be attained: the co-aptation of the
scion with a piece of root. Some grafters use only the upper portion
of the root, thinking the original collar of the seedling stock the
only point at which the most perfect and successful union between the
aërial and terrestrial portions of trees should or can be
effected--theoretically this may be very well, but the practice
constantly pursued, in myriads of cases, abundantly proves that the
grafting need not be restricted to this part, and that a perfect union
may be effected at any point of the root, and that this may even be
inverted. The very common practice has been to take two or more cuts
from the root, when it is of sufficient size and length; and though
some of our best propagators restrict themselves to two cuts from
each, others, who have experimented carefully, insist that the third
section will average as well as the others. A lot of trees, worked
especially for a test in this matter, gave the following results.
In 1859 an average lot of roots and scions, about fifty in each lot,
were treated as follows, White Pippin and Willow-leaf being used as
scions:--
White Pippin--No. 1, being on the first cut of the root, had made a
fair growth.
No. 2, being on the second cut, were quite as good or better.
No. 3, being on the third cut, were not quite so good as the others,
the ground being partially shaded by a large tree.
Another, of Willow-leaf--No. 1, on the 3d cut of root, very good
growth.
No. 2, on very slender roots, nearly as good.
No. 3, only 1 inch of root to 1 inch of scion; not so good growth nor
so good a strike, but shaded by a tree.
No. 4, on 2d cut of root, not so good as the third.
No. 5, on average lot, not waxed, as good as any.
No. 6, roots worked upside-down, mostly failed.
D.O. Reeder exhibited some 2-year old apple trees, worked on the root
inverted, they were of very good growth.
For root grafting, thrifty stocks are wanted of one or two years'
growth, the smoother and straighter the roots, the better. These
should be taken up from the seed-bed in the fall, selected, tied in
bundles, and stored in the cellar or cave, or buried in the soil where
they shall be accessible at any time, and where they will be kept
fresh and plump. The roots and scions having been prepared and under
shelter, the work of grafting may proceed at any time during the
winter. The stocks, if not clean, should be washed, and one hand trims
off the side rootlets. The grafter cuts a hundred scions of the
appropriate length, which he puts into a shallow box on the table; he
takes up a stock, cuts the slope near the collar, and a dextrous hand
will at the same time make the sloping cut to receive the first graft
and also the tongue, if that style of grafting is to be done, as is
usually practised. He then picks up a scion, from a lot which himself
or another hand has already prepared with a slope and tongue, and
adapts it to the root, the tongue keeping the two together; a portion
of the root is then cut off with the graft, and the process is
repeated upon the next section. Two or three or more grafts, are thus
made from one seedling root; the length of the sections vary from two
to four inches, according to the fancy of the operator, or of his
employer. Some persons recommend a long scion with a short root, and
others prefer to reverse those terms. The whole root graft should not
be more than six or seven inches long.
When any given number of scions are fitted to the roots, a boy
completes the process of grafting, by applying melted wax with a
brush, in which case they are dropped into water to harden the wax, or
they are wrapped with waxed strips of muslin or paper, or, better
still, they are tied with waxed thread. No. 3 cotton yarn is drawn
through a pan of melted wax, and wound upon a reel placed at the other
side of the room, so that the wax may harden. This waxed thread is a
very convenient tie; the graft being held in the left hand, the thread
is wound about it two or three turns; as the wax causes the bandage
to adhere to itself where it crosses, no knot is needed, and the
thread is broken off with a quick jerk.
In splice grafting, whether performed with any of the machines, or if
the slopes of root and scion be cut with the thin grafting knife, the
tying must be done by the same hand that selects and places the scion
upon the root. This does not admit of the same division of labor, and
the fingers, becoming sticky from the wax, cannot be so nimble, and
are unfit for cutting. When the lot is tied, they are set into the
box, which should be inclined at an angle, and interspersed with earth
or saw-dust; for transportation. Saw-dust, just as it comes from the
mill, neither wet nor dry, is preferred by some as a packing material,
and it has been found very efficacious, excluding and admitting the
air just in the right proportions to prevent desiccation, and to
promote the union, which very soon takes place between the graft and
the root, if the boxes be stored in the cellar. In an ice-house root
grafts have been kept in saw-dust more than a year, and then planted
and grown successfully. The boxes should be deep enough to receive the
whole graft--say from 10 to 12 inches--and then they can be packed
upon one another without injuring the scions; these should be
distinctly marked with the name and number, so as to be ready for
planting out in the spring.
Much discussion has been had upon the merits and demerits, or
disadvantages of root grafting, and much theoretical argument has been
brought against the practice; but beautiful trees are thus made in
immense numbers in the extensive nurseries of our country, and until
better arguments can be produced against the practice, nurserymen
will continue to graft on sections of root, such varieties, as are
suitable for this procedure--especially apples, in a large proportion
of the varieties cultivated, some pears, some peaches, grapes, and
other fruits.
Root grafting is now of almost universal application with the apple.
It has many advantages, which may be summed up as follows: Two or more
plants may be produced from the root of one stock; these may be made
with great rapidity; the work may all be performed in-doors and during
the whole winter season, when nothing can be done outside; they are of
small bulk, and great numbers may be stowed away in little space, they
may be transported to any distance in this condition, and are ready
for planting with the opening of spring, when they may be set in the
nursery rows at once; or, they may be bedded out in a small space and
mulched, to protect them from drouth, and the weeds can easily be kept
under. Another advantage of bedding out the root-grafts is, that they
may be assorted according to their size the next season, when
transplanted into the nursery rows. This very transplanting too is a
great advantage, for the roots will be much improved by the process.
The theoretical objections to root grafts have yielded to sound
philosophy, based on and supported by practical observation. The very
many advantages of this more economical and convenient and agreeable
process, will necessarily sustain root-grafting in this fast age, when
so many millions of trees are needed for the rapidly extending wants
of this nation of tree planters. We may, however, consider some of the
practical objections which have been brought forward against this
plan of multiplying the apple. In our very changeable climate, and
particularly in the North-west, upon the prairies, the cold of winter
often supervenes with great suddenness, after the young trees have
made a prolonged and vigorous growth in the fertile soil, and produces
terrible devastation among those that are there exposed, without
protection of any kind, to the rude blasts of the storm-king: in a
less degree, injury is very frequent with many such late-growing
kinds, at the first access of a severe frost; this is manifested in
the bursting of the bark near the base of the stem. The same thing is
not so often seen in the same varieties, when they have been budded or
stock grafted a foot or more from the ground upon hardy seedling
stocks, hence judicious propagators have selected the "tender"
varieties for this kind of working, and confine their root-grafting to
those less liable to the injury. There are other varieties which do
not readily and promptly form a strong upright growth, so as to be
profitable trees to the nurseryman if root grafted; these are selected
for stock working, either on strong seedlings, or upon hardy upright
sorts that have been root grafted for the purpose of being thus
double-worked. This plan has been pursued to a limited extent only,
but its advantages in the production of good trees of the slender
growing varieties, begin to be appreciated, and as the demand
increases, our intelligent nurserymen will very soon furnish the
requisite supply.
_Planting._--When the weather is fine, and the soil in good condition,
the root-grafts are to be set out with a dibble, by the line; they
should be planted rather deeply, one bud projecting above the surface
of the ground. The culture must be thorough, the plants should be
kept perfectly clean, but it is questionable whether the growth should
be pushed, late in the season; indeed, it is preferable to check the
vegetation at mid-summer. For this purpose it has been recommended to
cease cultivating the soil, or even to sow the ground with a heavy
seeding of oats, so as to check the growth before winter. In good
soils, with good culture, the average hight in the rows will be two
feet, but there is a great difference in the kinds; some will
considerably exceed this hight. Intelligent nurserymen no longer
endeavor to have an excessive growth in the first year, and many
prefer the bedding plan above alluded to.
_Trimming, Pinching, or Heading._--The growth during the first year is
generally a single shoot, sometimes two. If there be a second, it
should be subordinated by pinching off its extremity, never by
trimming it off; indeed, laterals should always be encouraged, and
this will be more and more the case, since the demand for low-headed
trees is increasing, as the laws of physiology are better understood.
A young tree, well furnished with laterals, is always more stocky, and
every way better, though not so tall as that which has been drawn up
to a single stem. To encourage this condition, some advise the
pinching out the terminal bud in the midst of the growing season,
which will cause the swelling and subsequent breaking of the lower
buds, so as to furnish plenty of laterals. If done later in the
season, especially with strong-growing varieties, a branching head may
be formed higher up, during the first season, making very pretty
trees. This is, however, seldom attempted with root-grafts the first
season, though it is very common for collar-grafted trees, and for
buds on strong stocks to make a fine branching growth the first year.
The second season the trees should all be headed-in, and the laterals
spurred-in early in the spring, or in mild weather during the winter,
if the scions are wanted. This method of making stocky plants cannot
be too highly commended, nor can the opposite plan, of trimming off
all the side branches, and even of stripping the leaves from the lower
part of the shoots, during the first summer, be too severely
condemned.
STOCK GRAFTING has many advocates, and for some varieties this plan is
preferable. The union may be effected at any point from the collar
upward. Formerly, the place was selected to suit the convenience of
the grafter, and many old orchards show very plainly where they were
worked, the stock or the scion having overgrown, and it is very
curious that some varieties may be indicated as good feeders of the
stock below them, and the contrary. At present, tree planters are more
fastidious, and object to these irregularities in the stems of their
trees. They will purchase nothing that shows the point of union above
ground, hence the more common use of collar grafting, as it has been
called, or the insertion of the scion at or near the surface of the
ground. Stocks that have been cultivated one or two years in the
nursery row, are selected for this purpose; the earth is removed from
them, they are cut off and grafted as they stand, and with their fine
strong roots undisturbed, the result of one summer's growth is very
satisfactory, making beautiful trees fit for the orchard. Older trees,
especially those with straight clean stems, are often grafted standard
high, so as to produce a fine salable tree at once, or in one season.
This is a very good plan with some of the slender and straggling
varieties, such as are called poor growers, and which are unprofitable
to the nurseryman when propagated in the usual manner. Grafting or
budding upon such stocks is also resorted to very often, when it is
desirable at once to furnish large, or salable trees of new varieties.
In grafting upon a large stock, or upon the tops of an old tree, the
process called cleft grafting is generally used. Here, as in all forms
of this process, the object to be attained, is the co-aptation of the
inner bark of both stock and scion. The latter is held in its place by
the clasping of the former, and is also covered by some material that
is pliant, and which will exclude the air and moisture.
The advantages of stock-grafting are the changing of an old tree from
bad to good fruit, which is produced in a few years; it is also
applicable to large stocks, and produces an immediate result, making
salable trees in one year. It is also desirable for some poor-growing
varieties, which are slow in making a tree from the ground; but it has
its disadvantages also. The nurseryman must wait until his stocks have
been grown one or more years in the nursery, his trees will sometimes
be larger than he desires, they will be apt to have the mark of the
grafting as a blemish upon the stalk sometimes during the life of the
tree; and worse than all, he is restricted to a brief period in the
spring, when he is obliged to perform the operation out of doors, and
often in very unpleasant weather.
As a result of all the discussions upon this subject, it is found that
stock-grafting, whether at the collar or at some distance above the
ground, is still practiced, and has many warm advocates, as a better
means of making the best trees. The only objections are the greater
expense of culture of the stocks, and greater labor in grafting; the
limited period at which the work can be performed, and the exposure of
the workman during its performance, which is often at a stormy season,
and always during a busy portion of the year. The trees too, in the
orchard, are often somewhat deformed by an irregularity of growth, and
have an enlargement either above or below the union, which is
unsightly.
The kind of grafting will depend upon the size of the stocks; splice
and whip-grafting on the smaller, and cleft-grafting on the larger
ones, must be practiced. The waxing may be done by any of the methods
indicated, according to the fancy; but it must always be more
thoroughly done in aerial, than in underground grafting, whether this
be in the collar or upon sections of the root; in the former the whole
of the cut surfaces must be covered, to prevent desiccation by the
winds, or the inroads of insects, or of wet from rains.
WAX.--Various combinations of the materials used in the preparation of
grafting-wax, have been recommended by different operators. The
desideratum being to have a material that shall be sufficiently
pliant, and at the same time firm enough to withstand the elevated
temperatures to which it may be exposed. A mean is preferred, neither
too hard nor too soft, and the proportions of the ingredients are
varied according as it is proposed to use it out of doors, or in the
house, in cold weather or warm.
A favorite recipe, with a practical nurseryman of great experience,
is:
Rosin, six parts, }
Bees-wax, one part, } melted together.
Tallow, one part, }
This is to be used warm, when grafting in the house.
For out-door work he used the following:
Rosin, four or five parts.
Bees-wax, one and one-half to two parts.
Linseed oil, one to one and one-half.
This is made into a mass to be applied by hand. A very pleasant and
neat mode of using the wax is to pour it when melted, upon thin muslin
or strong paper, and spread it thin with a spatula. The tissue is then
cut into strips of convenient size. The application to cotton yarn for
root-grafting, has already been mentioned.
The French use the preparation given below, sufficiently warm to be
liquid, but not so hot as to injure the tissues of the tree, and apply
it with a brush:
Black pitch 28 parts.
Burgundy pitch 28 parts.
Bees-wax 16 parts.
Grease 14 parts.
Yellow ochre 14 parts.
------------
Making 100 parts.[14]
Mr. Du Breuil also refers to Leport's liquid mastic in terms of
commendation, but speaks of it as a secret composition.
Downing recommends melting together:
Bees-wax 3 parts.
Rosin 3 parts.
Tallow 2 parts.
He says, the common wax of the French is
Pitch one-half pound.
Bees-wax one-half pound.
Cow-dung one pound.
To be boiled together, and laid on with a brush, and for using cold or
on strips of muslin, equal parts of tallow, bees-wax, and rosin, some
preferring a little more tallow.
J.J. Thomas, whose practical knowledge is proverbial, recommends for
its cheapness
Linseed oil one pint.
Rosin six pounds.
Bees-wax one pound.
Melted together, to be applied warm with a brush, or to be put on
paper or muslin, or worked with wet hands into a mass and drawn out
into ribbons.
The season for grafting is quite a prolonged one, if we include the
period during which it may be done in the house, and the ability we
have of retarding the scions by cold, using ice. It should be done
while the grafts are dormant, which is at any time from the fall of
the leaf until the swelling of the buds. As the grafts would be likely
to suffer from prolonged exposure, out-door grafting is done just
before vegetation commences in the spring, but may be prolonged until
the stocks are in full leaf, by keeping back the scions, in which
case, however, there is more danger to the stock unless a portion of
its foliage is allowed to remain to keep up the circulation; under
these circumstances, too, side-grafting is sometimes used with the
same view.
The stone fruits are worked first; cherries, plums, and peaches, then
pears and apples. With regard to grafting grapes, there is a
diversity of opinion. Some operators prefer very early in the season,
as in February, and others wait until the leaves have appeared upon
the vine to be grafted.
SCIONS OR GRAFTS are to be selected from healthy plants of the variety
we wish to propagate. They should be the growth of the previous year,
of average size, well developed, and with good buds, those having
flower buds are rejected. If the shoots be too strong, they are often
furnished with poor buds, and are more pithy, and therefore they are
more difficult to work and are less likely to grow. Grafts, cut from
young bearing orchards, are the best, and being cut from fruiting
trees, this enables us to be certain as to correctness of the
varieties to be propagated; but they are generally and most rapidly
collected from young nursery trees, and as an orchardist or nurseryman
should be able to judge of all the varieties he cultivates by the
appearance of their growth, foliage, bark, dots, etc., there is little
danger in taking the scions from such untested trees.
_Time for cutting Scions._--The scions may be cut at any time after
the cessation of growth in the autumn, even before the leaves have
fallen, until the buds burst in the spring, always avoiding severely
cold or frosty weather, because of the injury to the tree that results
from cutting at such a time, though the frost may not have injured the
scion. The best nurserymen prefer to cut them in the autumn, before
they can have been injured by cold. They should be carefully packed in
fine earth, sand, or sawdust, and placed in the cellar or cave. The
leaves stripped from them, make a very good packing material; moss is
often used, where it can be obtained, but the best material is
saw-dust. This latter is clean, whereas the sand and soil will dull
the knife. If the scions should have become dry and shriveled, they
may still be revived by placing them in soil that is moderately moist,
not wet--they should not, by any means, be placed in water, but should
be so situated that they may slowly imbibe moisture. When they have
been plumped, they should be examined by cutting into their tissues;
if these be brown, they are useless, but if alive, the fresh cut will
look clear and white, and the knife will pass as freely through them
as when cutting a fresh twig.
The after-treatment of the grafts consists in removing the sprouts
that appear upon the stock below the scion, often in great numbers.
These are called robbers, as they take the sap which should go into
the scion. It is sometimes well to leave a portion of these as an
outlet for excess. When the graft is tardy in its vegetation, and in
late grafting, it is always safest to leave some of these shoots to
direct the circulation to the part, and thus insure a supply to the
newly introduced scion; all should eventually be removed, so as to
leave the graft supreme.
It may sometimes be necessary to tie up the young shoot which pushes
with vigor, and may fall and break with its own weight before the
supporting woody fibre has been deposited; but a much better policy is
to pinch in the tip when but a few inches long, and thus encourage the
swelling and breaking of the lateral buds, and produce a more sturdy
result. This is particularly the case in stock-grafts and in renewing
an orchard by top-grafting.

BUDDING, or inoculating, is the insertion of eyes or buds. This is a
favorite method of propagation, which is practiced in the
multiplication of a great variety of fruits. The advantages of budding
consist in the rapidity and facility with which it is performed, and
the certainty of success which attends it. Budding may be done during
a long period of the growing season, upon the different kinds of trees
we have to propagate. Using but a single eye, it is also economical of
the scions, which is a matter of some importance, when we desire to
multiply a new and scarce variety.
It has been claimed on behalf of the process of budding, that trees,
which have been worked in this method, are more hardy and better able
to resist the severity of winter than others of the same varieties,
which have been grafted in the root or collar, and also that budded
trees come sooner into bearing. Their general hardiness will probably
not be at all affected by their manner of propagation; except perhaps,
where there may happen to be a marked difference in the habit of the
stock, such for instance as maturity early in the season, which would
have a tendency to check the late growth of the scion placed upon
it--the supplies of sap being diminished, instead of continuing to
flow into the graft, as it would do from the roots of the cutting or
root-graft of a variety which was inclined to make a late autumnal
growth. Practically, however, this does not have much weight, nor can
we know, in a lot of seedling stocks, which will be the late feeders,
and which will go into an early summer rest.
Certain varieties of our cultivated fruits are found to have a
remarkable tendency to make an extended and very thrifty growth,
which, continuing late into the autumn, would appear to expose the
young trees to a very severe trial upon the access of the first cold
weather, and we often find them very seriously injured under such
circumstances; the bark is frequently split and ruptured for several
inches near the ground. The twigs, still covered with abundant
foliage, are so affected by the frost, that their whole outer surface
is shriveled, and the inner bark and wood are browned; the latter
often becomes permanently blackened, and remains as dead matter in the
centre of the tree, for death does not necessarily ensue. Now
intelligent nurserymen have endeavored to avoid losses from these
causes, by budding such varieties upon strong well-established stocks,
though they are aware that these are not more hardy than some of the
cultivated varieties: a given number of seedling stocks has been found
to suffer as much from the severity of winter, as do a similar amount
of the grafted varieties taken at random.[15] That the serious
difficulty of bark-bursting occurs near the surface of the ground,
does seem to be an argument of some weight in favor of budding or
stock-grafting at a higher point. The earlier fruiting of budded trees
than those which have been root-grafted, does not appear to be a well
established fact, and therefore need not detain us; except to observe
that the stocks, upon which the buds were inserted, might have been
older by some years than the slip of root upon which the graft was
set, so that the fruiting of the former tree should count two or three
or more years further back than from the period of the budding. There
are so many causes which might have contributed toward this result of
earlier bearing, that we should not be too hasty in drawing
conclusions in this matter.
The philosophy of budding is very similar to that of grafting. The
latter process is performed when the plant-life is almost dormant, and
the co-apted parts are ready to take the initiative steps of
vegetation, and to effect their union by means of new adventitious
cells, before the free flow of sap in the growing season. Budding, on
the contrary, is done in the hight of that season and toward its
close, when the plants are full of well matured and highly organized
sap, when the cell circulation is most active, and the union between
the parts is much more immediate than in the graft; were it not so,
indeed, the little shield, with its actively evaporating surface of
young bark, must certainly perish from exposure to a hot dry
atmosphere. The _cambium_, or gelatinous matter, which is discovered
between the bark and the wood when they are separated, is a mass of
organizable cells. Mr. Paxton, using the gardener's expression, calls
it the "pulp." Budding is most successfully performed when this matter
is abundant, for then the vitality of the tree is in greatest degree
of exaltation.
The individuality of the bud was sufficiently argued in the first
section of this chapter, it need not now be again introduced, except
as appropriately to remind us of the fact where the propagation
depends upon this circumstance--the future tree must spring from the
single bud which is inserted. Mr. A.T. Thomson, in his Lectures on the
Elements of Botany, page 396, says:--"The individuality of buds must
have been suspected as early as the discovery of the art of budding,
and it is fully proved by the dissection of plants. * * Budding is
founded on the fact, that the bud, which is a branch in embryo, is a
distinct individual. It is essential that both the bud and the tree
into which it is inserted should not only be analogous in their
character, as in grafting with the scion, but both must be in a state
of growth at the time the operation is performed. The union, however,
depends much more upon the bud than upon the stock--the bud may be
considered a centre of vitality--vegetative action commences in the
bud, and extends to the stock, connecting them together."--"The vital
energy, however, which commences the process of organization in the
bud, is not necessarily confined to the germ, nor distinct from that
which maintains the growth of the entire plant; but it is so connected
with organization, that when this has proceeded a certain length, the
bud may be removed from the parent and attached to another, where it
will become a branch the same as if it had not been removed."
The season for budding has already been indicated in general terms, it
is usually done in mid-summer and the early part of autumn, reference
being had to the condition of the plants to be worked; these should be
in a thrifty growing state, the woody fibre should be pretty well
advanced, but growth by extension must still be active, or the needful
conditions will not be found. The "pulp" must be present between the
bark and the wood of the stock, so that the former can be easily
separated from the latter; in the language of the art, the bark must
"run;" this state of things will soon cease in most stocks, after the
formation of terminal buds on the shoots. The success of spring
budding, however, would appear to indicate that the cambium layer is
formed earlier in the season than is usually supposed; for whenever
the young leaves begin to be developed on the stock, "the bark will
run," and the buds may be inserted with a good prospect of success. In
this case we are obliged to use dormant buds that were formed the
previous year, and we have to exercise care in the preservation of
the scions, to keep them back by the application of cold, until the
time of their insertion.
