barn-yards, and after it becomes thoroughly saturated and intermixed
with the droppings of the stock, it is piled up to ferment, and the yard
is covered again with fresh muck."
Mr. N. Hart, Jr., of West Cornwall, Conn., writes:--"In the use of muck
we proceed as follows: Soon after haying we throw up enough for a year's
use, or several hundred loads. In the fall, the summer's accumulation in
hog-pens and barn cellars is spread upon the mowing grounds, and a
liberal supply of muck carted in and spread in the bottoms of the
cellars, ready for the season for stabling cattle. When this is well
saturated with the drippings of the stables, a new supply is added. The
accumulation of the winter is usually applied to the land for the corn
crop, except the finer portion, which is used to top-dress meadow land.
A new supply is then drawn in for the swine to work up. This is added to
from time to time, and as the swine are fed on whey, they will convert a
large quantity into valuable manure for top-dressing mowing land."
A difference of opinion exists as to the treatment of the compost. Some
hold it indifferent whether the peat and manure are mixed, or put in
layers when the composting begins. Others assert, that the fermentation
proceeds better when the ingredients are stratified. Some direct, that
the compost should not be stirred. The general testimony is, that
mixture, at the outset, is as effectual as putting up in layers; but,
if the manure be strawy, it is, of course, difficult or impracticable to
mix at first. Opinion also preponderates in favor of stirring, during or
after the fermentation.
Mr. Hoyt remarks:--"We are convinced, that the oftener a compost pile of
yard manure and muck is worked over after fermenting, the better. We
work it over and add to it a little more muck and other material, and
the air being thus allowed to penetrate it, a new fermentation or
heating takes place, rendering it more decomposable and valuable."
Rev. Wm. Clift, writes:--"Three or four loads of muck to one of stable
manure, put together in the fall or winter in alternate layers, forked
over twice before spreading and plowing in, may represent the method of
composting."
Mr. Adams White, of Brooklyn, Conn., proceeds in a different manner. He
says:--"In composting, 20 loads are drawn on to upland in September, and
thrown up in a long pile. Early in the spring 20 loads of stable manure
are laid along side, and covered with the muck. As soon as it has heated
moderately, the whole is forked over and well mixed."
Those who have practiced making peat composts with their yard, stable,
and pen manure, almost invariably find them highly satisfactory in use,
especially upon light soils.
A number of years ago, I saw a large pile of compost in the farm-yard of
Mr. Pond, of Milford, Conn., and witnessed its effect as applied by that
gentleman to a field of sixteen acres of fine gravelly or coarse sandy
soil. The soil, from having a light color and excessive porosity, had
become dark, unctuous, and retentive of moisture, so that during the
drouth of 1856, the crops on this field were good and continued to
flourish, while on the contiguous land they were dried up and nearly
ruined. This compost was made from a light muck, that contained but
three _per cent._ of ash (more than half of which was sand), and but 1.2
_per cent._ of nitrogen, in the air-dry state--(twenty _per cent._ of
water). Three loads of this muck were used to one of stable manure.
Here follow some estimates of the value of this compost by practical
men. They are given to show that older statements, to the same effect,
cannot be regarded as exaggerated.
Mr. J. H. Stanwood, of Colebrook, Conn., says:--"Experiments made by
myself, have confirmed me in the opinion that a compost of equal parts
of muck and stable manure is equal to the same quantity of stable
manure."
Mr. Daniel Buck, Jr., of Poquonock, Conn., remarks:--"8 loads of muck
and 4 of manure in compost, when properly forked over, are equal to 12
loads of barn-yard manure on sandy soil."
Rev. Wm. Clift, of Stonington, Conn., writes:--"I consider a compost
made of one load of stable manure and three of muck, equal in value to
four loads of yard manure."
Mr. N. Hart, Jr., of West Cornwall, Conn., observes of a peat sent by
him for analysis:--"We formerly composted it in the yard with stable
manure, but have remodeled our stables, and now use it as an absorbent
and to increase the bulk of manure to double its original quantity. We
consider the mixture more valuable than the same quantity of stable
manure." Again, "so successful has been the use of it, that we could
hardly carry on our farming operations without it."
Mr. Adams White, of Brooklyn, Conn., states:--"The compost of equal
bulks of muck and stable manure, has been used for corn (with plaster in
the hill,) on dry sandy soil to great advantage. I consider the compost
worth more per cord than the barn-yard manure."
_Night Soil_ is a substance which possesses, when fresh, the most
valuable fertilizing qualities, in a very concentrated form. It is also
one which is liable to rapid and almost complete deterioration, as I
have demonstrated by analyses. The only methods of getting the full
effect of this material are, either to use it fresh, as is done by the
Chinese and Japanese on a most extensive and offensive scale; or to
compost it before it can decompose. The former method, will, it is to be
hoped, never find acceptance among us. The latter plan has nearly all
the advantages of the former, without its unpleasant features.
When the night soil falls into a vault, it may be composted, by simply
sprinkling fine peat over its surface, once or twice weekly, as the case
may require, _i. e._ as often as a bad odor prevails. The quantity thus
added, may be from twice to ten times the bulk of the night soil,--the
more within these limits, the better. When the vault is full, the mass
should be removed, worked well over and after a few days standing, will
be ready to use to manure corn, tobacco, etc., in the hill, or for any
purpose to which guano or poudrette is applied. If it cannot be shortly
used, it should be made into a compact heap, and covered with a thick
stratum of peat. When signs of heating appear, it should be watched
closely; and if the process attains too much violence, additional peat
should be worked into it. Drenching with water is one of the readiest
means of checking too much heating, but acts only temporarily. Dilution
with peat to a proper point, which experience alone can teach, is the
surest way of preventing loss. It should not be forgotten to put a thick
layer of peat at the bottom of the vault to begin with.
Another excellent plan, when circumstances admit, is, to have the
earth-floor where the night soil drops, level with the surface of the
ground, or but slightly excavated, and a shed attached to the rear of
the privy to shelter a good supply of peat as well as the compost
itself. Operations are begun by putting down a layer of peat to receive
the droppings; enough should be used to absorb all the urine. When this
is nearly saturated, more should be sprinkled on, and the process is
repeated until the accumulations must be removed to make room for more.
Then, once a week or so, the whole is hauled out into the shed, well
mixed, and formed into a compact heap, or placed as a layer upon a
stratum of peat, some inches thick, and covered with the same. The
quantity of first-class compost that may be made yearly upon any farm,
if due care be taken, would astonish those who have not tried it. James
Smith, of Deanston, Scotland, who originated our present system of
Thorough Drainage, asserted, that the excrements of one man for a year,
are sufficient to manure half an acre of land. In Belgium the manure
from such a source has a commercial value of $9.00 gold.
It is certain, that the skillful farmer may make considerably more than
that sum from it in New England, _per annum_. Mr. Hoyt, of New Canaan,
Conn., says:--
"Our privies are deodorized by the use of muck, which is sprinkled over
the surface of the pit once a week, and from them alone we thus prepare
annually, enough "poudrette" to manure our corn in the hill."
_Peruvian Guano_, so serviceable in its first applications to light
soils, may be composted with muck to the greatest advantage. Guano is an
excellent material for bringing muck into good condition, and on the
other hand the muck most effectually prevents any waste of the costly
guano, and at the same time, by furnishing the soil with its own
ingredients, to a greater or less degree prevents the exhaustion that
often follows the use of guano alone. The quantity of muck should be
pretty large compared to that of the guano,--a bushel of guano will
compost six, eight, or ten of muck. Both should be quite fine, and
should be well mixed, the mixture should be moist and kept covered with
a layer of muck of several inches of thickness. This sort of compost
would probably be sufficiently fermented in a week or two of warm
weather, and should be made and kept under cover.
If no more than five or six parts of muck to one of guano are employed,
the compost, according to the experience of Simon Brown, Esq., of the
Boston _Cultivator_, (Patent Office Report for 1856), will prove
injurious, if placed in the hill in contact with seed, but may be
applied broadcast without danger.
The _Menhaden_ or "_White fish_", so abundantly caught along our Sound
coast during the summer months, or any variety of fish may be composted
with muck, so as to make a powerful manure, with avoidance of the
excessively disagreeable stench which is produced when these fish are
put directly on the land. Messrs. Stephen Hoyt & Sons, of New Canaan,
Conn., make this compost on a large scale. I cannot do better than to
give entire Mr. Edwin Hoyt's account of their operations, communicated
to me several years ago.
"During the present season, (1858,) we have composted about 200,000
white fish with about 700 loads (17,500 bushels) of muck. We vary the
proportions somewhat according to the crop the compost is intended for.
For rye we apply 20 to 25 loads per acre of a compost made with 4,500
fish, (one load) and with this manuring, no matter how poor the soil,
the rye will be as large as a man can cradle. Much of ours we have to
reap. For oats we use less fish, as this crop is apt to lodge. For corn,
one part fish to ten or twelve muck is about right, while for grass or
any top-dressing, the proportion of fish may be increased."
"We find it is best to mix the fish in the summer and not use the
compost until the next spring and summer. Yet we are obliged to use in
September for our winter rye a great deal of the compost made in July.
We usually compost the first arrivals of fish in June for our winter
grain; after this pile has stood three or four weeks, it is worked over
thoroughly. In this space of time the fish become pretty well
decomposed, though they still preserve their form and smell
outrageously. As the pile is worked over, a sprinkling of muck or
plaster is given to retain any escaping ammonia. At the time of use in
September the fish have completely disappeared, bones and fins
excepted."
"The effect on the muck is to blacken it and make it more loose and
crumbly. As to the results of the use of this compost, we find them in
the highest degree satisfactory. We have raised 30 to 35 bushels of rye
per acre on land that without it could have yielded 6 or 8 bushels at
the utmost. This year we have corn that will give 60 to 70 bushels per
acre, that otherwise would yield but 20 to 25 bushels. It makes large
potatoes, excellent turnips and carrots."
Fish compost thus prepared, is a uniform mass of fishy but not
putrefactive odor, not disagreeable to handle. It retains perfectly all
the fertilizing power of the fish. Lands, manured with this compost,
will keep in heart and improve: while, as is well known to our coast
farmers, the use of fish alone is ruinous in the end, on light soils.
It is obvious that _any other easily decomposing animal matters, as
slaughter-house offal, soap boiler's scraps, glue waste, horn shavings,
shoddy, castor pummace, cotton seed-meal, etc., etc._, may be composted
in a similar manner, and that several or all these substances may be
made together into one compost.
In case of the composts with yard manure, guano and other animal
matters, the alkali, _ammonia_, formed in the fermentation, greatly
promotes chemical change, and it would appear that this substance, on
some accounts, excels all others in its efficacy. The other alkaline
bodies, _potash_, _soda_ and _lime_, are however scarcely less active in
this respect, and being at the same time, of themselves, useful
fertilizers, they also may be employed in preparing muck composts.
_Potash-lye_ and _soda-ash_ have been recommended for composting with
muck; but, although they are no doubt highly efficacious, they are too
costly for extended use.
The other alkaline materials that may be cheaply employed, and are
recommended, are _wood-ashes_, leached and unleached, _ashes of peat_,
_shell marl_, (consisting of carbonate of lime,) _quick lime_, _gas
lime_, and what is called "_salt and lime mixture_."
With regard to the proportions to be used, no very definite rules can be
laid down; but we may safely follow those who have had experience in the
matter. Thus, to a cord of muck, which is about 100 bushels, may be
added, of unleached wood ashes twelve bushels, or of leached wood ashes
twenty bushels, or of peat ashes twenty bushels, or of marl, or of gas
lime twenty bushels. Ten bushels of quick lime, slaked with water or
salt-brine previous to use, is enough for a cord of muck.
Instead of using the above mentioned substances singly, any or all of
them may be employed together.
The muck should be as fine and free from lumps as possible, and must be
intimately mixed with the other ingredients by shoveling over. The mass
is then thrown up into a compact heap, which may be four feet high. When
the heap is formed, it is well to pour on as much water as the mass will
absorb, (this may be omitted if the muck is already quite moist,) and
finally the whole is covered over with a few inches of pure muck, so as
to retain moisture and heat. If the heap is put up in the Spring, it may
stand undisturbed for one or two months, when it is well to shovel it
over and mix it thoroughly. It should then be built up again, covered
with fresh muck, and allowed to stand as before until thoroughly
decomposed. The time required for this purpose varies with the kind of
muck, and the quality of the other material used. The weather and
thoroughness of intermixture of the ingredients also materially affect
the rapidity of decomposition. In all cases five or six months of summer
weather is a sufficient time to fit these composts for application to
the soil.
Mr. Stanwood of Colebrook, Conn., says: "I have found a compost made of
two bushels of unleached ashes to twenty-five of muck, superior to
stable manure as a top-dressing for grass, on a warm, dry soil."
N. Hart, Jr., of West Cornwall, Conn., states: "I have mixed 25 bushels
of ashes with the same number of loads of muck, and applied it to 3/4 of
an acre. The result was far beyond that obtained by applying 300 lbs.
best guano to the same piece."
The use of "_salt and lime mixture_" is so strongly recommended, that a
few words may be devoted to its consideration.
When quick-lime is slaked with a brine of common salt (chloride of
sodium), there are formed by double decomposition, small portions of
caustic soda and chloride of calcium, which dissolve in the liquid. If
the solution stand awhile, carbonic acid is absorbed from the air,
forming carbonate of soda: but carbonate of soda and chloride of calcium
instantly exchange their ingredients, forming insoluble carbonate of
lime and reproducing common salt.
When the fresh mixture of quick-lime and salt is incorporated with _any
porous body_, as soil or peat, then, as Graham has shown, _unequal
diffusion_ of the caustic soda and chloride of calcium occurs from the
point where they are formed, through the moist porous mass, and the
result is, that the small portion of caustic soda which diffuses most
rapidly, or the carbonate of soda formed by its speedy union with
carbonic acid, is removed from contact with the chloride of calcium.
Soda and carbonate of soda are more soluble in water and more strongly
alkaline than lime. They, therefore, act on peat more energetically than
the latter. It is on account of the formation of soda and carbonate of
soda from the lime and salt mixture, that this mixture exerts a more
powerful decomposing action than lime alone. Where salt is cheap and
wood ashes scarce, the mixture may be employed accordingly to advantage.
Of its usefulness we have the testimony of practical men.
Says Mr. F. Holbrook of Vermont, (Patent Office Report for 1856, page
193.) "I had a heap of seventy-five half cords of muck mixed with lime
in the proportion of a half cord of muck to a bushel of lime. The muck
was drawn to the field when wanted in August. A bushel of salt to six
bushels of lime was dissolved in water enough to slake the lime down to
a fine dry powder, the lime being slaked no faster than wanted, and
spread immediately while warm, over the layers of muck, which were about
six inches thick; then a coating of lime and so on, until the heap
reached the height of five feet, a convenient width, and length enough
to embrace the whole quantity of the muck. In about three weeks a
powerful decomposition was apparent, and the heap was nicely overhauled,
nothing more being done to it till it was loaded the next Spring for
spreading. The compost was spread on the plowed surface of a dry sandy
loam at the rate of about fifteen cords to the acre, and harrowed in.
The land was planted with corn and the crop was more than sixty bushels
to the acre."
Other writers assert that they "have decomposed with this mixture, spent
tan, saw dust, corn stalks, swamp muck, leaves from the woods, indeed
every variety of inert substance, and in _much shorter time than it
could be done by any other means_." (Working Farmer, Vol. III. p. 280.)
Some experiments that have a bearing on the efficacy of this compost
will be detailed presently.
There is no doubt that the soluble and more active (caustic) forms of
alkaline bodies exert a powerful decomposing and solvent action on peat.
It is asserted too that the _nearly insoluble and less active matters of
this kind_, also have an effect, though a less complete and rapid one.
Thus, _carbonate of lime_ in the various forms of chalk, shell marl,[6]
old mortar, leached ashes and peat ashes, (for in all these it is the
chief and most "alkaline" ingredient,) is recommended to compost with
peat. Let us inquire whether carbonate of lime can really exert any
noticeable influence in improving the fertilizing quality of peat.
In the case of vitriol peats, carbonate of lime is the cheapest and most
appropriate means of destroying the noxious sulphate of protoxide of
iron, and correcting their deleterious quality. When carbonate of lime
is brought in contact with sulphate of protoxide of iron, the two bodies
mutually decompose, with formation of sulphate of lime (gypsum) and
carbonate of protoxide of iron. The latter substance absorbs oxygen from
the air with the utmost avidity, and passes into the peroxide of iron,
which is entirely inert.
The admixture of any earthy matter with peat, will facilitate its
decomposition, and make it more active chemically, in so far as it
promotes the separation of the particles of the peat from each other,
and the consequent access of air. This benefit may well amount to
something when we add to peat one-fifth of its bulk of marl or leached
ashes, but the question comes up: Do these insoluble mild alkalies exert
any direct action? Would not as much soil of any kind be equally
efficacious, by promoting to an equal degree the contact of oxygen from
the atmosphere?
There are two ways in which carbonate of lime may exert a chemical
action on the organic matters of peat. Carbonate of lime, itself, in the
forms we have mentioned, is commonly called insoluble in water. It is,
however, soluble to a very slight extent; it dissolves, namely, in about
30,000 times its weight of pure water. It is nearly thirty times more
soluble in water saturated with carbonic acid; and this solution has
distinct alkaline characters. Since the water contained in a heap of
peat must be considerably impregnated with carbonic acid, it follows
that when carbonate of lime is present, the latter must form a
solution, very dilute indeed, but still capable of some direct effect on
the organic matters of the peat, when it acts through a long space of
time. Again, it is possible that the solution of carbonate of lime in
carbonic acid, may act to liberate some ammonia from the soluble
portions of the peat, and this ammonia may react on the remainder of the
peat to produce the same effects as it does in the case of a compost
made with animal matters.
Whether the effects thus theoretically possible, amount to anything
practically important, is a question of great interest. It often happens
that opinions entertained by practical men, not only by farmers, but by
mechanics and artisans as well, are founded on so untrustworthy a basis,
are supported by trials so destitute of precision, that their accuracy
may well be doubted, and from all the accounts I have met with, it does
not seem to have been well established, practically, that composts made
with carbonate of lime, are better than the peat and carbonate used
separately.
Carbonate of lime (leached ashes, shell marl, etc.), is very well to use
_in conjunction with_ peat, to furnish a substance or substances needful
to the growth of plants, and supply the deficiencies of peat as regards
composition. Although in the agricultural papers, numerous accounts of
the efficacy of such mixtures are given, we do not learn from them
whether these bodies exert any such good effect upon the peat itself, as
to warrant the trouble of making a _compost_.
4.--_Experiments by the author on the effect of alkaline bodies in
developing the fertilizing power of Peat._
During the summer of 1862, the author undertook a series of experiments
with a view of ascertaining the effect of various composting materials
upon peat.
Two bushels of peat were obtained from a heap that had been weathering
for some time on the "Beaver Meadow," near New Haven. This was
thoroughly air-dried, then crushed by the hand, and finally rubbed
through a moderately fine sieve. In this way, the peat was brought to a
perfectly homogeneous condition.
Twelve-quart flower-pots, new from the warehouse, were filled as
described below; the trials being made in duplicate:--
Pots 1 and 2 contained each 270 grammes of peat.
Pots 3 and 4 contained each 270 grammes of peat, mixed-with 10 grammes
of ashes of young grass.
Pots 5 and 6 contained each 270 grammes of peat, 10 grammes of ashes,
and 10 grammes of carbonate of lime.
Pots 7 and 8 contained each 270 grammes of peat, 10 grammes of ashes,
and 10 grammes of slaked (hydrate of) lime.
Pots 9 and 10 contained each 270 grammes of peat, 10 grammes of ashes,
and 5 grammes of lime, slaked with strong solution of common salt.
Pots 11 and 12 contained each 270 grammes of peat, 10 grammes of ashes,
and 3 grammes of Peruvian guano.
In each case the materials were thoroughly mixed together, and so much
water was cautiously added as served to wet them thoroughly. Five
kernels of dwarf (pop) corn were planted in each pot, the weight of each
planting being carefully ascertained.
The pots were disposed in a glazed case within a cold grapery,[7] and
were watered when needful with pure water. The seeds sprouted duly, and
developed into healthy plants. The plants served thus as tests of the
chemical effect of carbonate of lime, of slaked lime, and of salt and
lime mixture, on the peat. The guano pots enabled making a comparison
with a well-known fertilizer. The plants were allowed to grow until
those best developed, enlarged above, not at the expense of the peat,
etc., but of their own lower leaves, as shown by the withering of the
latter. They were then cut, and, after drying in the air, were weighed
with the subjoined results.

Let us now examine the above results. The experiments 1 and 2,
demonstrate that the peat itself is deficient in something needful to
the plant. In both pots, but 4.2 grammes of crop were produced, a
quantity two and a half times greater than that of the seeds, which
weighed 1.59 grammes. The plants were pale in color, slender, and
reached a height of but about six inches.
Nos. 3 and 4 make evident what are some of the deficiencies of the peat.
A supply of mineral matters, such as are contained in all plants, being
made by the addition of _ashes_, consisting chiefly of phosphates,
carbonates and sulphates of lime, magnesia and potash, a crop is
realized nearly eight times greater than in the previous cases; the
yield being 32.44 grammes, or 20-1/2 times the weight of the seed. The
quantity of ashes added, viz.:--10 grammes, was capable of supplying
every mineral element, greatly in excess of the wants of any crop that
could be grown in a quart of soil. The plants in pots 3 and 4 were much
stouter than those in 1 and 2, and had a healthy color.
The experiments 5 and 6 appear to demonstrate that _carbonate of lime_
considerably aided in converting the peat itself into plant-food. The
ashes alone contained enough carbonate of lime to supply the wants of
the plant in respect to that substance. More carbonate of lime could
only operate by acting on the organic matters of the peat. The amount of
the crop is raised by the effect of carbonate of lime from 32.44 to
38.44 grammes, or from 20-1/2 to 25-1/2 times that of the seed.
Experiments 7 and 8 show, that _slaked lime_ has more effect than the
carbonate, as we should anticipate. Its influence does not, however,
exceed that of the carbonate very greatly, the yield rising from 38.44
to 42.22 grammes, or from 25-1/2 to 28-1/2 times the weight of the seed.
In fact, quick-lime can only act as such for a very short space of time,
since it rapidly combines with the carbonic acid, which is supplied
abundantly by the peat. In experiments 7 and 8, a good share of the
influence exerted must therefore be actually ascribed to the carbonate,
rather than to the quick-lime itself.
In experiments 9 and 10, we have proof that the "_lime and salt
mixture_" has a greater efficacy than lime alone, the crop being
increased thereby from 42.22, to 46.42 grammes, or from 28-1/2 to 30-1/2
times that of the seed.
Finally, we see from experiments 11 and 12 that in all the foregoing
cases it was a limited supply of _nitrogen_ that limited the crop; for,
on adding Peruvian guano, which could only act by this element (its
other ingredients, phosphates of lime and potash, being abundantly
supplied in the ashes), the yield was carried up to 53.78 grammes, or
35-1/2 times the weight of the seed, and 13 times the weight of the crop
obtained from the unmixed peat.
5.--_The Examination of Peat (muck and marsh-mud) with reference to its
Agricultural Value._
Since, as we are forced to conclude, the variations in the composition
of peat stand in no recognizable relations to differences of appearance,
it is only possible to ascertain the value of any given specimen by
actual trial or by chemical investigation.
The method _by practical trial_ is usually the cheaper and more
satisfactory of the two, though a half year or more is needful to gain
the desired information.
It is sufficient to apply to small measured plots of ground, each say
two rods square, known quantities of the fresh, the weathered, and the
composted peat in order, by comparison of the growth and _weight_ of the
crop, to decide the question of their value.
Peat and its composts are usually applied at rates ranging from 20 to 40
wagon or cart loads per acre. There being 160 square rods in the acre,
the quantity proper to a plot of two rods square (= four square rods,)
would be one half to one load.
The composts with stable manure and lime, or salt and lime mixture, are
those which, in general, it would be best to experiment with. From the
effects of the stable manure compost, could be inferred with safety the
value of any compost, of which animal manure is an essential ingredient.
One great advantage of the practical trial on the small scale is, that
the adaptation of the peat or of the compost to the _peculiarities of
the soil_, is decided beyond a question.
It must be borne in mind, however, that the results of experiments can
only be relied upon, when the plots are accurately measured, when the
peat, etc., are applied in known quantities, and when the crops are
separately harvested and carefully weighed.
If experiments are made upon grass or clover, the gravest errors may
arise by drawing conclusions from the appearance of the standing crop.
Experience has shown that two clover crops, gathered from contiguous
plots differently manured, may strikingly differ in appearance, but
yield the same amounts of hay.
The _chemical examination_ of a peat may serve to inform us, without
loss of time, upon a number of important points.
To test a peat for _soluble iron salts_ which might render it
deleterious, we soak and agitate a handful for some hours, with four or
five times its bulk of warm soft water. From a _good fresh-water peat_
we obtain, by this treatment, a yellow liquid, more or less deep in
tint, the taste of which is very slight and scarcely definable.
From a _vitriol peat_ we get a dark-brown or black solution, which has a
bitter, astringent, metallic or inky taste, like that of copperas.
_Salt peat_ will yield a solution having the taste of salt-brine, unless
it contains iron, when the taste of the latter will prevail.
On evaporating the water-solution to dryness and heating strongly in a
China cup, a _vitriol peat_ gives off white choking fumes of sulphuric
acid, and there remains, after burning, brown-red oxide of iron in the
dish.
The above testings are easily conducted by any one, with the ordinary
conveniences of the kitchen.
Those that follow, require, for the most part, the chemical laboratory,
and the skill of the practised chemist, for satisfactory execution.
Besides testing for soluble iron compounds, as already indicated, the
points to be regarded in the chemical examination, are:--
1st. _Water or moisture._--This must be estimated, because it is so
variable, and a knowledge of its quantity is needful, if we will compare
together different samples. A weighed amount of the peat is dried for
this purpose at 212 deg. F., as long as it suffers loss.
2d. The _proportions of organic matter and ash_ are ascertained by
carefully burning a weighed sample of the peat. By this trial we
distinguish between peat with 2 to 10 _per cent._ of ash and peaty soil,
or mud, containing but a few _per cent._ of organic matter.
This experiment may be made in a rough way, but with sufficient accuracy
for common purposes, by burning a few lbs. or ozs. of peat upon a piece
of sheet iron, or in a sauce pan, and noting the loss, which includes
both _water_ and _organic matter_.
3d. As further regards the organic matters, we ascertain _the extent to
which the peaty decomposition has taken place_ by boiling with dilute
solution of carbonate of soda. This solvent separates the humic and
ulmic acids from the undecomposed vegetable fibers.
For practical purposes this treatment with carbonate of soda may be
dispensed with, since the amount of undecomposed fiber is gathered with
sufficient accuracy from careful inspection of the peat.
Special examination of the organic acids is of no consequence in the
present state of our knowledge.
4th. The _proportion of nitrogen_ is of the first importance to be
ascertained. In examinations of 30 samples of peat, I have found the
content of nitrogen to range from 0.4 to 2.9 _per cent._, the richest
containing seven times as much as the poorest. It is practically a
matter of great moment whether, for example, a Peruvian guano contains
16 _per cent._ of nitrogen as it should, or but one-seventh that amount,
as it may when grossly adulterated. In the same sense, it is important
before making a heavy outlay in excavating and composting peat, to know
whether (as regards nitrogen) it belongs to the poorer or richer sorts.
This can only be done by the complicated methods known to the chemist.
5th. The estimation of _ammonia_ (actual or ready-formed,) is a matter
of scientific interest, but subordinate in a practical point of view.
6th. _Nitric acid_ and _nitrates_ can scarcely exist in peat except
where it is well exposed to the air, in a merely moist but not wet
state. Their estimation in composts is of great interest, though
troublesome to execute.
7th. As regards the ash, its red color indicates _iron_. Pouring
hydrochloric acid upon it, causes effervescence in the presence of
_carbonate of lime_. This compound, in most cases, has been formed in
the burning, from humate and other organic salts of lime. _Sand_, or
_clay_, being insoluble in the acid, remains, and may be readily
estimated.
_Phosphoric acid_ and alkalies, especially _potash_, are, next to lime,
the important ingredients of the ash. _Magnesia_ and _sulphuric acid_,
rank next in value. Their estimation requires a number of tedious
operations, and can scarcely be required for practical purposes, until
more ready methods of analyses shall have been discovered.
8th. The quantity of _matters soluble in water_ has considerable
interest, but is not ordinarily requisite to be ascertained.
6.--_Composition of Connecticut Peats_.
In the years 1857 and 1858, the author was charged by the Connecticut
State Agricultural Society[8] with the chemical investigation of 33
samples of peat and swamp muck, sent to him in compliance with official
request.
In the foregoing pages, the facts revealed by the laborious analyses
executed on these samples, have been for the most part communicated,
together with many valuable practical results derived from the
experience of the gentlemen who sent in the specimens. The analytical
data themselves appear to me to be worthy of printing again, for the
information of those who may hereafter make investigations in the same
direction.--See Tables I, II, and III, p.p. 89, 90, and 91.
The specimens came in all stages of dryness. Some were freshly dug and
wet, others had suffered long exposure, so that they were air-dry; some
that were sent in the moist state, became dry before being subjected to
examination; others were prepared for analysis while still moist.
A sufficient quantity of each specimen was carefully pulverized,
intermixed, and put into a stoppered bottle and thus preserved for
experiment.
The analyses were begun in the winter of 1857 by my assistant, Edward H.
Twining, Esq. The samples 1 to 17 of the subjoined tables were then
analyzed. In the following year the work was continued on the remaining
specimens 18--33 by Dr. Robert A. Fisher. The method of analysis was the
same in both cases, except in two particulars.
In the earlier analyses, 1 to 17 inclusive, the treatment with carbonate
of soda was not carried far enough to dissolve the whole of the soluble
organic acids. It was merely attempted to make _comparative_
determinations by treating all alike for the same time, and with the
same quantity of alkali. I have little doubt that in some cases not more
than one-half of the portion really soluble in carbonate of soda is
given as such. In the later analyses, 18 to 33, however, the treatment
was continued until complete separation of the soluble organic acids was
effected.
By acting on a peat for a long time with a hot solution of carbonate of
soda, there is taken up not merely a quantity of organic matter, but
inorganic matters likewise enter solution. Silica, oxyd of iron and
alumina are thus dissolved. In this process too, sulphate of lime is
converted into carbonate of lime.
The total amount of these soluble inorganic matters has been determined
with approximate accuracy in analyses 18 to 33.
In the analyses 1 to 17 the collective amount of matters soluble in
water was determined. In the later analyses the proportions of organic
and inorganic matters in the water-solution were separately estimated.
The process of analysis as elaborated and employed by Dr. Fisher and the
author, is as follows:
I. To prepare a sample for analysis, half a pound, more or less, of the
substance is pulverized and passed through a wire sieve of 24 meshes to
the inch. It is then thoroughly mixed and bottled.
II. 2 grammes of the above are dried (in tared watch-glasses) at the
temperature of 212 degrees, until they no longer decrease in weight. The
loss sustained represents the _amount of water_, (according to MARSILLY,
Annales des Mines, 1857, XII., 404, peat loses carbon if dried at a
temperature higher than 212 degrees.)
III. The capsule containing the residue from I. is slowly heated to
incipient redness, and maintained at that temperature until the organic
matter is entirely consumed. The loss gives the total amount of
_organic_, the residue the total amount of _inorganic_ matter.
NOTE.--In peats containing sulphate of the protoxide of iron, the loss
that occurs during ignition is partly due to the escape of sulphuric
acid, which is set free by the decomposition of the above mentioned salt
of iron. But the quantity is usually so small in comparison with the
organic matter, that it may be disregarded. The same may be said of the
combined water in the clay that is mixed with some mucks, which is only
expelled at a high temperature.
IV. 3 grammes of the sample are digested for half an hour, with 200
cubic centimeters (66.6 times their weight,) of boiling water, then
removed from the sand bath, and at the end of twenty-four hours, the
clear liquid is decanted. This operation is twice repeated upon the
residue; the three solutions are mixed, filtered, concentrated, and
finally evaporated to dryness (in a tared platinum capsule,) over a
water bath. The residue, which must be dried at 212 degrees, until it
ceases to lose weight, gives the _total amount soluble in water_. The
dried residue is then heated to low redness, and maintained at that
temperature until the organic matter is burned off. The loss represents
the amount of _organic matter soluble in water_, the ash gives the
quantity of _soluble inorganic matter_.
V. 1 gramme is digested for two hours, at a temperature just below the
boiling point, with 100 cubic centimeters of a solution containing 5
_per cent._ of crystallized carbonate of soda. It is then removed from
the sand bath and allowed to settle. When the supernatant liquid has
become perfectly transparent, it is carefully decanted. This operation
is repeated until all the organic matter soluble in this menstruum is
removed; which is accomplished as soon as the carbonate of soda solution
comes off colorless. The residue, which is to be washed with boiling
water until the washings no longer affect test papers, is thrown upon a
tared filter, and dried at 212 degrees. It is the _total amount of
organic and inorganic matter insoluble in carbonate of soda_. The loss
that it suffers upon ignition, indicates the amount of _organic matter_,
the ash gives the _inorganic_ matter.
NOTE.--The time required to insure perfect settling after digesting with
carbonate of soda solution, varies, with different peats, from 24 hours
to several days. With proper care, the results obtained are very
satisfactory. Two analyses of No. 6, executed at different times, gave
_total insoluble in carbonate of soda_--1st analysis 23.20 _per cent._;
2d analysis 23.45 _per cent._ These residues yielded respectively 14.30
and 14.15 _per cent._ of ash.
VI. The quantity of _organic matter insoluble in water but soluble in
solution of carbonate of soda_, is ascertained by deducting the joint
weight of the amounts soluble in water, and insoluble in carbonate of
soda, from the total amount of organic matter present. The _inorganic
matter insoluble in water, but soluble in carbonate of soda_, is
determined by deducting the joint weight of the amounts of inorganic
matter soluble in water, and insoluble in carbonate of soda, from the
total inorganic matter.
VII. The amount of nitrogen is estimated by the combustion of 1 gramme
with soda-lime in an iron tube, collection of the ammonia in a standard
solution of sulphuric acid, and determination of the residual free acid
by an equivalent solution of caustic potash and a few drops of tincture
of cochineal as an indicator.
The results of the analyses are given in the following Tables. Table I.
gives the direct results of analysis. In Table II. the analyses are
calculated on dry matter, and the nitrogen upon the organic matters.
Table III. gives a condensed statement of the external characters and
agricultural value[9] of the samples in their different localities, and
the names of the parties supplying them.

_Condition at Time of Analysis,
_No._ Reputed value, etc._
1. Lewis M. Norton |air-dry, tough, compact, heavy; from bottom;
| 3 to 4 feet deep; very good in compost.
2. " " | " tough, compact, heavier than 1, from
| near surface; very good in compost.
3. " " | " coherent but light, from between 1 and
| 2, very good in compost.
4. Messrs. Pond & Miles| " coherent but light, surface peat,
| considered better than No. 5; good in
| compost.

| depth of 3 feet, good in compost.
6. Samuel Camp | " hard lumps, half as good as yard manure,
| in compost equal to yard manure.
7. Russell U. Peck | " is good fresh, long exposed, half as
| good as barn-yard manure.
8. Rev. B. F. Northrop | " light, easily crushed masses containing
| sand, has not been used alone, good in
| compost.
9. J. H. Stanwood |moist, hard lumps, used fresh good after first

14. Philip Scarborough | " after exposure over winter, has
| one-third value of yard-manure.
15. Adams White | " hard lumps, good in compost, causes
| great growth of straw.
16. Paris Dyer | " easily crushed lumps, largely admixed
| with soil.
17. Perrin Scarborough | " well-characterized "vitriol peat;" in
| compost, after 1 year's exposure, gives
| indifferent results.
18. Geo. K. Virgin | " light, coherent surface peat; sample
| long exposed; astonishing results on
| sandy soil.
19. " " |moist, crumbly, contains much sand, four feet
| from surface.
20. " " |wet.
21. Solomon Mead |air-dry, light, porous, coherent from grass
| roots; long weathered, good; fresh,
| better in compost.
22. Edwin Hoyt | " loose, light, much mixed with soil,
| good in compost.

FOOTNOTES:
[2] The oxygen thus absorbed by water, serves for the respiration of
fish and aquatic animals.
[3] This sample contained also fish-bones, hence the larger content of
nitrogen was not entirely due to absorbed ammonia.
[4] Reichardt's analyses are probably inaccurate, and give too much
ammonia and nitric acid.
[5] These analyses were executed--A by Professor G. F. Barker; B by Mr.
O. C. Sparrow; C by Mr. Peter Collier.
[6] _Shell marl_, consisting of fragments and powder of fresh-water
shells, is frequently met with, underlying peat beds. Such a deposit
occurs on the farm of Mr. John Adams, in Salisbury, Conn. It is eight to
ten feet thick. An air-dry sample, analyzed under the writer's
direction, gave results as follows:
"Water 30.62
{soluble in water 0.70}
Organic matter { } 6.52
{insoluble in water 5.82}
Carbonate of lime 57.09
Sand 1.86
Oxide of iron and alumina, with traces of potash,
magnesia, sulphuric and phosphoric acid 3.91
-------
100.00
Another specimen from near Milwaukee, Wis., said to occur there in
immense quantities underlying peat, contained, by the author's
analysis--
Water 1.14
Carbonate of lime 92.41
Carbonate of magnesia 3.43
Peroxide of iron with a trace of phosphoric acid 0.92
Sand 1.60
