_General Remarks._--No one certain variety of soil can be said to be the
best for raisin purposes, and both in different countries, as well as in
the same district, various varieties of soils are valued equally. Every
raisin district has, however, its favorite soil, which is supposed to
have some peculiar advantages for the raisin grapes, but upon closer
investigation we generally find other varieties of soils which are not
inferior. Growers who have succeeded with raisin grapes on one variety
of soil are only too apt to consider this kind preferable to any other.
This is especially the case in California, where soils vary so much and
where in some districts it is difficult to find forty acres with a
uniform soil. Whether the soil is black, red or gray, it makes but very
little difference, as long as it is rich and susceptible of the highest
state of cultivation and has the faculty of retaining moisture. The
deeper and richer the soil the better the Muscatel grape will thrive and
produce, and as such soils are most generally found along the banks of
creeks and rivers, or in their bottoms and sinks, we might conclude that
in such localities the best soils for the Muscat grape may be found.
Other varieties of raisin grapes, such as the Malaga (California) and
the Sultana, do well in less rich soil; indeed, they bear profitably in
places where the Muscat would be a failure. It is therefore important
for every vineyardist to carefully select his soil and then plant on it
the proper variety of vine.
_Malaga._--The soils of Malaga are of various kinds. The best is a
reddish loam containing much gravel, both coarse and fine. This soil is
very stiff and hard, and when dry is as solid as a brick. The red color
is derived from oxide of iron or other iron compounds, which many of the
best vineyardists consider a most desirable element in any raisin soil.
The upland vineyards, or those on the slope of the hills, contain soils
of decomposed clay and slate mixed with more or less gravel and sand.
The Dehesa lands contain alluvial deposits of a black or gray color.
_Valencia and Denia._--In this district we find soils of many different
grades and colors. The sandy and gravelly soils are considered as
producing the finest flavored raisins, and those having the best keeping
qualities, while the rich, loamy soils of the valleys produce raisins of
inferior flavor and keeping qualities, but of larger size and more per
acre. For economical reasons, the latter soils are preferred, as they
alone can be irrigated and made to produce large crops. Some of the best
vineyards in this district contain a gray, ashy soil, quite similar to
the white ash of the Kings river lands, while others are growing on a
red clayey loam similar to the California red soil.
_Smyrna._--The raisin-grapes of Smyrna in Asia Minor are almost
exclusively grown on a white limestone soil, which consists of
decomposed white rocks mixed with a stiff ocher-colored loam. This soil
is so rocky that it must first be cleared, and the large rocks are
carried away and used for boundary walls. This is the soil in the coast
districts. In the interior the Sultana vines, as well as the Muscats,
are replaced by fig orchards and other trees which delight in sandy
soil,--too sandy to produce profitable raisin crops.
_Zante._--The soils of Zante, the home of the Currant grape, are of
various kinds. The heavy marl of the plains, which contains a large
percentage of gypsum or sulphate of lime, is considered the best; indeed
the gypsum is by many considered indispensable, or at least highly
beneficial, to the above variety of grape. Other soils are red clay,
gray marl and gravelly loam, all containing an abundance of lime. The
Currant grape grows well and produces well on all these different soils,
but does the best on the gypsum soil, which is therefore the most
valued. On other soils the bunches are less solid, and the quantity of
grapes produced is somewhat less, while their quality is inferior.

for Drying.]
_Chile._--The Huasco grape grows in the valley of Huasco, on the coast
of Chile, in a soil that is very light and red, containing a great
quantity of sand. While very light in weight, this soil is said to be
very rich in plant food, and yields good crops.
_Fresno._--The Fresno soils are of several kinds, but the three
principal varieties are red or chocolate-colored loam, white or gray
ashy soil, and a light, very sandy, loam. To this may be added the
deeper gray bottom soils or alluvial deposits of the Kings river. Each
one of these varieties have different grades more or less suitable to
the Muscatel grape. The best grades of each are equally valuable, while
again the poorer grades are not to be recommended. The deep
chocolate-colored loam is by many preferred, and the largest and most
successful raisin vineyards are now located on this soil. But even in
the best districts the soil varies to such an extent, that while one
twenty-acre field will yield 250 boxes of raisins to the acre, the
adjoining field, with only a slight change in the soil, will yield only
seventy-five boxes to the acre. The best grades of the white ashy soil
are also very good, and almost identical with the gray bottom-land
deposits of Kings river. The light sandy soil should be avoided for
Muscat grapes, but may do for Malaga and Sultanas, especially if
judiciously fertilized.
_Other Soils in San Joaquin Valley._--In Merced the best soil is heavy
chocolate-colored loam, in places redder, in others darker, almost
blackish. It is generally mixed with some gravel. As a rule, all the red
soil in the San Joaquin valley is of the same characteristics, and well
suited to the Muscat grape, provided the ground is sufficiently level.
In Tulare county the proper soil for the Muscat is found to be the
bottom lands of Kings and Kaweah rivers, as well as the deposits of the
smaller creeks. This variety of gray alluvial loam is exceedingly
fertile, and there is none superior for the Muscat grape. But an
admixture of alkali often spoils soils which otherwise would be
considered the very best. A similar soil is found in Kern county,
especially near Kern Lake, and which must be rated among the best in the
State, its color being a deep bluish gray. The vineyards of Yolo and
Solano counties are located on a very similar soil, rich in humus, lime
and phosphates, but more yellowish or pale chocolate colored.
_Orange County._--A similar rich alluvial deposit is found in Orange
county in the fertile district known as Santa Ana valley. The soil
around Anaheim, Santa Ana, Orange and Tustin consists of a more or less
dark alluvial loam of unsurpassed fertility, and especially adapted to
the Muscat grape. It varies as to the percentage of sand and gravel. The
sandiest soil in this district, while less rich, brings the earliest
grapes, which come to perfect ripeness several weeks before those grown
on the heavier soils, but the latter produce the best raisins.
_Redlands and Riverside._--The Redlands soil of the mesa lands is
reddish, rather darker than the same quality of soil in Riverside and
Fresno. It is mixed with sand and gravel, and partakes strongly of the
nature of the red or chocolate-colored loams of the State. The Lugonia
bottom soil consists of a very sandy loam, on which the Muscat grape
has proved a failure. The best Riverside soil is red or
chocolate-colored sandy loam, so often spoken of. Towards Rincon we find
alluvial bottom soils producing grapes of superb quality and size. The
soil of the San Bernardino district resemble the red Fresno soils, while
the white ashy soil is not found there.
_El Cajon._--The El Cajon valley soils are of three or more kinds: Rich
red clay mixed with gravel, with the color changing from lighter
chocolate to deeper reddish. This is a very desirable soil,--a steel
gray or slate gray adobe with much gravel of a coarse nature; a black
adobe with some gravel; an alluvial sandy loam consisting of decomposed
granite mixed with much vegetable matter and humus. The El Cajon soils,
while sandy and gravelly, produce exceedingly sweet and highly flavored
grapes but comparatively small crops.
_Subsoils._--The subsoil in a raisin vineyard is of great importance.
Properly irrigated soils, if they are sufficiently rich, need not
necessarily be very deep, as the raisin grapes, especially the Muscat,
seldom extend deeper than eight feet below the surface. Even from four
to five feet of rich soil may be considered as enough in irrigated
vineyards, where the water is abundant. In poorer soils, or in districts
with less irrigation, the roots of the vines penetrate much deeper, and
the importance of the subsoil in such cases is apparent. Any rich
subsoil will serve our purpose. It is always best to thoroughly
investigate the subsoil before the vineyard is planted, and in doing
this the following points must be considered: The subsoil should be as
rich as possible, and there should, in no instance, be less than four
feet of rich top soil. _Very_ sandy soil or pure sand is not a proper
subsoil for raisin grapes. Such soil will cause the top soil to dry too
quickly after each irrigation, and will cause the top soil to leach out,
while it besides gives no nourishment to the vines. Hardpan is not
desirable, not even admissible, except in places that are or will become
subirrigated. Alkali or salty subsoils will soon spoil the quality of
even the best top soil. This especially is the case in irrigated
districts, where the salts of the subsoil are carried to the top by the
rising waters or by the continued irrigation. Hardpan which readily
dissolves when wet is not injurious.
_Hardpan Soils._--While I have alluded to them already, a few more
remarks on these soils are here in place. The hardpan consists of a
stratum of hard soil or hard rocky substance below the top soil. The
depth at which the hardpan is found varies. In places where it is
situated eight or ten feet below the top surface it does but very little
harm, and may even prove beneficial in localities where water for
irrigation is scarce, as it checks too rapid drainage. If the hardpan is
situated closer to the top soil, it may seriously interfere with the
vines, and if too close, or say within two or three feet from the top,
it makes such soils entirely unfit for raisin grapes. If situated
somewhat lower down, say from four to six feet, the hardpan does no
great harm in subirrigated districts, while, in places where irrigation
is not used, it leaves the top soil too shallow and too dry. But
allowance must always be made as to the nature of the hardpan. Some
varieties of hardpan are so hard that they can best be compared to
regular stratified rocks, impenetrable to the roots of the vines, and
impervious to water. Other hardpans again are softer, and allow the vine
roots to penetrate more or less readily, while some again are so soft
that they dissolve in water and make good soil for the vines. If the
hardpan is very shallow, it may pay to blast holes through it, in order
to allow the roots of the vines to penetrate to lower soils. But if the
hardpan is thick and hard, and if there is no immediate prospect of
subirrigation, it is better to use such land for some other purpose than
for raisin-vines, which will only pay properly if grown under the most
favorable circumstances, and on the best and deepest soils.
As to the nature of the hardpan, a few remarks may prove of interest.
The hardpan can best be compared to a stalactite formation similar to
those found in various caves. It has been formed very much in the same
way as they were. In caves the rainwater, that seeps down from the top
surface, dissolves various substances, especially carbonates (and
silicates even) which again are deposited on the underside of the cave
roof. This precipitation of hard material is caused both by evaporation
of the water, as well as by attraction and adhesion. Such redeposition
of dissolved minerals is seen for instance if solutions of salt in water
are passed through tasteless and clean sand. The water will come through
sweet and tasteless, the salt having adhered to the surface of the sand
grains. Similarly, if a hole is dug near the seashore in the sand, the
salt water will seep through, and form a well of more or less tasteless
drinking water. In the formation of hardpan, this is exactly what has
taken place. The rainwater has dissolved certain elements, such as
carbonates of lime, or carbonates of sodium and various other salts, and
in its way through the lower strata of the soil these dissolved elements
have again been taken up by the sand and cemented it together. Thus it
is explained why hardpan upon examination is so often found to resemble
sand or sandstone: the lower sandy strata of the soil have been
especially effective in causing the lime in the water to adhere to the
numerous surfaces of every individual grain of sand. In hog-wallow
districts the hardpan is found principally between the individual
hog-wallows, but rarely in or under them. The rainwater has here carried
the minerals in the soil to the deeper places between the hog-wallows,
in which it has accumulated to a greater extent than anywhere else, and
thus formed a heavier hardpan. In flooding the hog-wallows, the top of
every hog-wallow is seen to settle and fall in, there being no hardpan
below it, if the sides of the hog-wallow are steep. Where the hardpan
consists principally of lime compounds, its chemical composition is not
detrimental to the vines. But where the hardpan is cemented by alkalies
more or less soluble in water, these deleterious substances will
dissolve and rise to the surface to the great detriment or even to the
total destruction of the vineyard.
_Comparative Value of Soils._--The river bottom soils, or soils formed
by the deposit of creeks, are with few exceptions rich and deep, and
contain in abundance all the elements necessary to produce a superior
Muscat grape. Such soils are, however, often injured by subsoils
containing mineral deposits, which will injure the vines, or by
hardpans, which will cause the soil to dry out. Poor soils will not
prove profitable, and rather than plant vines on such soils it would be
better to plant no vines at all. The rich soils are not only the
heaviest producers, but the vines grown on them are stronger and
healthier and in every way better able to resist the attacks of insects
and fungi and the ravages of other inexplicable diseases. But regardless
of these advantages the various soils leave their effects on the grapes,
some of them producing sweet and very keeping raisins, while others
cause large berries and bunches, which bring the highest market price.
Thus the lighter and drier soils produce richer flavored and sweeter
raisins than the wet and rich soils, which again produce the largest and
handsomest grapes. On the latter soils the raisins when cured will be
found to be dark and covered with a heavy bloom, while the raisins from
the sandier or gravelly soils are lighter in color and with less
pronounced bloom. The keeping quality of the raisins from gravelly soils
is well known. In California the keeping quality of the raisins is
seldom inquired into, as our raisins keep remarkably well and are in
this respect superior to those grown in Spain. This may be from the
effect of our drier climate more than from any certain quality in our
soils.
As a rule it may be said that poor soil causes the raisins to mature
earlier than the rich, heavy loams, and on this account the latter are
to be greatly preferred, as the earliest raisins in any district are
never as good as the bulk of the crop, and are in demand rather as a
curiosity, and for the purpose of supplying an early market, than
through any superior qualities. In some districts there is such a great
difference in the time of ripening upon the various soils that the
grapes grown on the earliest soils are used only as table grapes fresh.
In planting a raisin vineyard, the future profits depend upon the choice
of land, and it is far better to pay a high price for the best land than
to take the inferior land as a gift. Few of those who now enter upon
raisin culture take the proper care in selecting the land, neither do
they sufficiently, if at all, realize the advantages of the rich soil,
nor the disadvantages of the poor land.
_Alkali Soils._--While nothing but first-class land is to be recommended
for raisin vineyards, and alkali lands are of all soils those least
suitable for our purpose, still a consideration of these lands will
interest many raisin-grape growers. The best lands for raisin purposes
in California are often contiguous to alkali lands, or to land
containing more or less traces of alkali. A vineyard on the best soil
contains often spots charged with alkali, and it may be inconvenient for
the grower to allow these spots to lie idle, and he would prefer to fill
them up with vines. The first work must then be to get rid of the alkali
or reduce it to such an extent that it will not prove injurious. The
general alkali lands are classed in three kinds, according to the
quality of the alkali.
1st. Alkali salts, such as carbonates and borates. These are greatly
detrimental to the vines, and no vines could be expected to do well in
such soils, as even the smallest percentage of this alkali is injurious
or even ruinous to the crop. In clayey soils these alkalies cause the
clay to harden in such a way that no good tilth can be obtained. The
land may be plowed ever so much, it will only turn up in chunks and
never become properly pulverized. These true alkali salts consist
principally of carbonate of sodium (sal-soda) or of carbonate of
potassium (saleratus). _Remedies_: Gypsum, land-plaster or leaching with
water.
2d. A second class of alkalies are the sulphates and chlorides, all
soluble in water. Such salts are: Magnesium chloride (bittern),
magnesium sulphate (Epsom salt), calcium chloride, etc. These salts,
when not present in too large quantities, are easily counteracted by
lime.
3d. A third class of alkalies is composed of neutral salts, such as
chloride of sodium (common salt), sulphate of sodium (Glauber salt),
sulphate of potassium, all soluble in water, but not convertible into
less injurious substances by lime or gypsum. These salts do not bake the
soil, but rather contribute towards keeping it loose and mellow.
The remedies which are practical and not too expensive may be divided
into several classes, which, if used in combination, may prove
effective, while each one of them used separately would fail.
1st. Leaching with water. All soluble salts may be leached with water.
The alkali land should be checked and so ditched that the water from
each check can be drained into a waste ditch. But, besides these waste
ditches, drain ditches should be made for the purpose of draining off
the water, say to a depth of four feet below the surface. The _modus
operandi_ consists in first flooding the soil, and while the check is
yet full the floodgates are opened and the water drawn off into the
waste ditch, when the water will carry off the salts which have been
dissolved in it. A second or third flooding should be allowed to settle
in the soil and be drained off below into the drain ditches. The
drawback to common leaching is that under certain circumstances the
water may deposit its alkali in lower strata, especially if they are
sandy, and there form hardpan or alkali accumulations. A much better
method is under-drainage by means of pipes or gravel drains constructed
all through the tract at certain regular distances. This under-drainage,
if properly constructed under conditions favorable for its perfect
working, is by far the best method of freeing alkali soils from their
superfluous salts. To what extent this system is practical depends upon
circumstances. To reclaim large districts by this method may not prove
economical as long as good land is plentiful and cheap, but where
smaller alkali tracts are surrounded by soil, and where it is of
importance to get a uniform plantation, under-drainage by pipes or
common drains is both the surest and most practical solution of the
alkali problem. Under-drainage is strongly recommended by Prof. E. W.
Hilgard, who has repeatedly pointed out its value, and who has called
the author’s special attention to this as yet little understood remedy.
2d. Deep and constant plowing. Deep and frequent plowing acts in various
ways. By being mixed with a larger quantity of soil, the alkali is
diluted sufficiently to not cause any serious injury to the crops, the
damage generally being done near the surface. Constant plowing also
prevents evaporation, which carries the alkali to the surface and
deposits it there. This method can only be successful when the alkali
salts are limited in quantity, and no one need expect to be able to rid
badly charged lands from their alkali by plowing it under.
3d. By plowing under green or dry crops. If grain can be made to grow on
the alkali land at all the turning under of it, either green or dry,
will in course of time greatly reduce the alkali. The turned-under
stubble or straw forms in decaying an acid, which in many instances will
combine with and counteract the effects of the alkali. Similarly, straw
stacks spread on alkali spots and plowed under will considerably reduce
the alkali. But manure containing ammonia and other salts should not be
used, as it will, on the contrary, only increase the alkali by adding
other or similar salts to those already in the soil.
4th. Cropping. If water, either in the form of sufficient rain or as
irrigation can be had, alkali lands can be reclaimed by cropping. It is
amply proved that beets and carrots, as well as other plants, such as
salt-bush (_Chenopodium_), take up large quantities of alkali salts, and
in the course of a few years render alkali soils available for grain.
Wheat also extracts alkalies, and repeated croppings with grain will in
the course of time prepare the soil for vines and trees. Bermuda grass
will completely remove the alkali from soils to the depth at which the
roots can penetrate, and must be recommended for the worst places.
Afterwards, cropping with annual crops may be advisable before vines are
finally planted on such reclaimed lands. The Australian salt-bushes, or
_Chenopodium_, extract alkalies, and are besides liked by stock. They
should be introduced to alkali lands and take the place of the
California native salt-bushes, which are not eaten by stock. While being
real desert plants, they yet require some moisture in the soil, but they
could probably be grown anywhere on the alkali lands in this State where
the rainfall is over three or four inches.
5th. By chemicals. The use of chemicals of various kinds in
counteracting the alkali is not resorted to by our farmers as it should
be. The principle upon which chemicals can be used is that obnoxious or
greatly injurious alkalies may be changed into less obnoxious and less
injurious salts, or even into fertilizers. The most available of these
chemical compounds are gypsum (sulphate of lime) and lime (carbonate of
lime). When the alkali consists mainly of carbonates, such as carbonate
of sodium (sal-soda) or potassium carbonate (saleratus), in other words
of the class which we have designated as class number one, the most
dangerous and worst class of alkalies to combat, gypsum may be used as
an antidote or rather as a means to convert these alkalies into alkalies
of the second class, or the sulphates. The principle upon which this is
done is to displace the sulphate in the gypsum and force it to combine
with the alkali (sodium carbonate) and form sulphate of sodium (Glauber
salt), an alkali belonging to the third class of alkalies, and which is
twenty times less injurious to vegetation than is class number one. The
change is made on the following principle, and might be thus
illustrated: To the alkali in the soil (carbonate of sodium), add
sulphate of lime. As soon as the mixture is made with sufficient water,
a change will take place, and the substances (carbonate of sodium and
sulphate of lime) will form new compounds. Thus we will get, out of
those two substances, two new compounds, _viz._, carbonate of lime and
sulphate of sodium. Of these, carbonate of lime is not injurious to
vegetable life, and sulphate of sodium (Glauber salt) is only injurious
when present in large quantities. The carbonate of lime is not soluble
in water, but the sulphate of sodium is, and can consequently be
eliminated by underdraining or by flooding, as we have previously
described.
To know when gypsum can be used is not necessarily a scientific matter.
Mix some of the alkali in a tumbler with water, and allow the mixture to
settle. In another tumbler mix some gypsum and water, and allow it to
settle. Then mix the two clear liquids, which, if gypsum is an antidote
and the proper thing to use, will be turbid or milky through the
chemical combinations which take place. If the water remains clear,
gypsum will not prove an antidote to the alkali under consideration. The
use of lime is based very much on the same principle. If the second
class of alkalies are present, and lime is added, the changes that take
place may be illustrated as follows: Epsom salt (magnesium sulphate)
combined with calcium carbonate, will form two new compounds, _viz._,
gypsum (calcium sulphate) and magnesium carbonate, both of which
substances are less injurious to crops. But, as I have already stated,
raisin-vines prefer soils which are naturally free from alkali, and
should never be planted on soils which cannot readily be reclaimed.
Chemical antidotes may do where the alkali occurs in a few spots mixed
in among tracts of good soil, but where the whole field must be
reclaimed some other crop than vines had better be first attempted.
There is too much good and suitable soil in California, and until all
this is occupied the alkali soils had better be given up to other crops
than vines.
_Fertilizing._--To this date but few grape-growers manure their soil.
California has not yet been engaged in the raisin business twenty years,
and her vineyards are comparatively virgin. The first raisin vineyards
were planted on the deepest and richest soil, the soil which would
naturally hold out the longest, but the croppings of a raisin vineyard
are enormous, and when from eight to ten tons of green grapes have been
taken from the soil year after year, it is but natural that the land
should become gradually exhausted. In Spain it is considered that even
the richest soils require manuring after ten years of constant cropping
with Muscats, and the same experience is likely to become ours in
California. So far, I know of not one vineyard which has yielded Muscat
grapes for ten continuous years and still keeps yielding as much as
formerly. Yearly the crop must become less, and finally will not be
large enough to pay. The manuring of the Muscatel vines is fully
understood in Spain, where all kinds of manures are used. When home
manures fail in supply, the Spaniards use imported fertilizers, such as
Mexican phosphates, etc. This fertilizer brings in Spain sixty-five
dollars per ton, and is brought there from our very doors,--the Gulf of
Lower California. It could be laid down here for, and is actually sold
here now at, forty dollars per ton, or twenty-five dollars less than in
Spain; still to my knowledge only very few raisin-growers in Fresno use
it for their vines. In one year one of these succeeded, with the aid of
this phosphate, in raising the crop of an acre of Sultana grapes from a
very poor yield to over eight tons. The grapes were grown on a piece of
sandy soil of the kind well known to Fresno vine-growers, and which is
generally considered as less suited to raisins, lacking in fact in more
than one of the necessary qualities of a good raisin soil.
It is certainly a wrong policy to crop the soil until the grape crops
begin to fail. The soil will then be so exhausted of several of its
ingredients, that it will take the most scientific treatment to bring it
back again to what it was formerly, and it is even questionable if this
could be done in a way that would prove profitable. Experience in Spain
teaches that vineyards which formerly used to yield from eight to ten
tons of green grapes to the acre now, after years of neglect, only yield
two tons to the acre, and even with expensive manuring can in no way be
brought back to their former fertility. On the other hand, we know that
vineyards which have been fertilized from the beginning have for fifty
years been kept up in apparently as good condition as at first; it is
accordingly this method that must be recommended. The manure or
fertilizer must be varied occasionally. In rotation, phosphates, bone
dust, guano, stable manure, sheep manure, lime and plaster of Paris or
gypsum may be used, but it is best to have every variety of soil in the
vineyard analyzed, and to apply from year to year that kind of
fertilizer which is particularly needed. The phosphates are those which
will first give out in our California soils. Phosphates must therefore
be considered as the best fertilizers we can use, but the quantity to be
used must always be determined by a practical chemist. Of these chemical
fertilizers, it is dangerous to use too much, as they might injure the
vines, and from fifty to a few hundred pounds to the acre may in some
instances suffice and produce better crops than would four or five times
as much. But, regardless of chemical fertilizers, the cautious
raisin-grower should endeavor to return to the soil as much as he
possibly can out of the wastes of his crop. The refuse of stems and
berries, which are wasted at the stemmer and in the packing-house,
should not be burned, as is generally the case, but returned to the
vineyard, and applied one year on one piece of ground, and another year
on some other piece. If, however, these wastes must be used as fuel in
the dryer, etc., the ashes should be carefully collected and spread over
the soil, and kept dry and shaded until thus used.
Another most valuable fertilizer generally wasted is the trimmings. In
our careless California farming, these trimmings of the vines are put in
piles on the roads, outside of the vineyards, and there burned. Thus the
ground loses the most powerful soluble salt, which would greatly
increase the yield of grapes and the profits to the farmer. Where the
vines are planted far enough apart, the trimmings may be burned between
the rows of the vines without injury to them, but, when the vines are
set close, there is no other way than to carefully collect the ashes and
spread them evenly over the soil. Some vineyardists use large troughs
made of galvanized iron and perforated with holes. These vats are drawn
through the vineyard by a team, and scatter the ashes evenly over the
soil. The vats may be so constructed that the cuttings are burned in
them directly as they are being pulled along, thus saving much labor as
well as ashes. Such contrivances will probably only prove profitable in
large vineyards, where there are long rows and few turnings for the
teams. Even the stable manure in our State is not used as it should be.
It is hardly possible to understand how vineyardists can be thoughtless
enough to haul loads upon loads of stable manure on their roads or in
holes and waste places, while their vines adjoining are suffering from
the want of sufficient nourishment. In the irrigated districts, this is
a very common sight, and the wet places on the road are often deep with
manure and strongly smelling of ammonia. If the manure had been placed
around the vines, the increase in crops would probably have been
sufficient to enable the owner to macadamize or otherwise permanently
fix the roads.
