MR. NEWTON'S EXPERIMENTS.

The Hon. Willoughby Newton, of Westmoreland County, was one of the

earliest and most successful experimenters in the use of guano in

Virginia. He owns large and productive farms on the Potomac, but on

account of the forest land being more healthy for a residence, he bought

a tract of it for that purpose; not having any design of ever putting it

into cultivation. In fact, it was so poor he could not. The manure of

the farm, if it had not been wanted there, was several miles

distant--too far to haul; and so the land lay an uncultivated,

unprofitable barren waste around his fine mansion; but it did not lay so

very long after he discovered the renovating power of guano. It is now

annually covered with broad fields of wheat, from which he has realized

upwards of twenty bushels to the acre; and the most luxuriant growths of

clover upon which he can pasture any amount of stock he pleases, where

three years previous a goat would have found difficulty in sustaining

life. Mr. Newton's first experiment--what was then an experiment is now

a certainty--was made with African guano. But we will give the account

of his operations in his own straight-forward, easily understood,

farmer-like language.

"In the effect of _guano_, especially the Peruvian, I have never been

disappointed. I have used it now for four years, with entire

satisfaction having each year been induced to enlarge my expenditure,

until last year it reached eight hundred dollars, and for the crop of

wheat this fall it exceeds one thousand. I have observed with

astonishment its effect in numerous instance on the poor "forest lands"

alluded to in a former part of this address. What the turnip and sheep

husbandry have done for the light lands of Great Britain, the general

use of guano promises to do for ours. Lands a few years ago deemed

entirely incapable of producing wheat, now produce the most luxuriant

crops. From 15 to 20 bushels for one sowed, is the ordinary product on

our poorest lands, from the application of 200 lbs. of Peruvian guano. I

may remark, it is not usual, in Eastern Virginia, to sow more than a

bushel of wheat to the acre, and that I deem amply sufficient. Upon this

subject I hope a few details may not be considered tedious or

uninteresting. I applied last fall $350 worth of guano, partly Peruvian

and partly Patagonian, on a poor farm "in the forest," which cost a few

years ago four dollars an acre, and reaped 1089 bushels of beautiful

wheat from 78 sowed. Forty-six bushels were sowed on fallow, (both guano

and wheat put in with the cultivator, followed by a heavy harrow,) and

yielded 790 bushels or over 17-1/4 for one. A considerable part of this

was dressed with Patagonian guano, and was much inferior to the other

portion. A lot on which 15 bushels was sowed, and dressed with Peruvian

guano, was threshed separately, and yielded 301 bushels, or over 20 for

one. The whole cost of the farm was $1520, and I have good reason to

expect with a favorable season from the crop now sowed and dressed with

guano, a bushel of wheat for every dollar of the prime cost of the farm.

Many other instances of profit from the use of guano, equally striking

have occurred among my neighbors and friends, but I confine myself to

those stated, because having come under my immediate observation, I can

vouch for their entire accuracy. It has been frequently objected to the

use of guano, that it is not permanent. It would be unreasonable to

expect great permanent improvement from a manure so active, and which

yielded go large a profit on the first crop. Yet I have seen some

striking evidences of its permanency in heavy crops of clover,

succeeding wheat, and in the increase of the crop of wheat on a second

application. As an instance, I may mention that two years ago I sowed

upon a single detached acre of "forest land," one bushel of wheat and

dressed it with a barrel of African guano, costing $4, and the yield was

seventeen bushels. Last fall the same land, after remaining one year in

clover, was again sowed with one bushel of wheat and dressed with 140

lbs. of Peruvian guano, costing $3, and the product was 22 bushels. Yet

I would advise no one to rely upon guano exclusively. Its analysis shows

that it contains salts of ammonia, alkaline phosphates and the other

mineral elements necessary to produce the grain of wheat, but is

deficient in most of the elements of the straw and roots of the plants.

Hence, (says Liebig) 'a rational agriculturist, in using guano, cannot

dispense with stable dung.' We should, therefore, be careful not to

exhaust the soil of organic manures, but by retaining the straw of the

wheat, and occasionally a crop of clover, which plant contains a large

percentage of the alkaline carbonates, which are entirely wanting in

Guano, furnish all the elements necessary to the entire wheat plant. In

this view of the subject, and for many other reasons that I cannot stop

to enumerate, there cannot be, when guano is extensively used, a more

judicious rotation than the Pamunky five field system, in which clover

occupies a prominent place. I have now enumerated some of the most

prominent means by which you may "keep your land rich." I would not

discourage the use of others. Science is daily making discoveries in the

art of enriching the earth, and we should discard nothing, without a

trial, which promises to be useful; always bearing in mind that the

wisest economy is entirely consistent with the most liberal expenditure,

in the purchase of manures, provided we take care, by judicious

experiments and observation, to ascertain their efficacy, and that we

get back our capital, with an actual _net_ profit _in cash_, on all our

investments. This latter caution is indispensable, in our country, where

new lands are so abundant and cheap, that highly improved farms can

never be rated in the market at their true value."

"The various manures compounded by chemists and manufacturers, should

also engage your careful attention. They should not be recklessly thrown

aside as humbugs, without trial or investigation, nor adopted and

extensively used with blind confidence in their efficacy. I have used

many of these manures by way of experiment, and the profit realized upon

them has not justified me in enlarging my operations. Poudrette,

manufactured in Baltimore; Bommers manure, Chappel's fertilizer and

Kentish & Co.'s prepared guano, (used, it is true, upon a small scale,)

have not realized the promises made in their behalf. Yet I would by no

means discourage the praiseworthy efforts of the manufacturers, and hope

they will persevere until, by lessening the bulk and increasing the

power of their compounds, they may be able to prepare an article that

for cheapness, convenience of application and efficacy, shall equal or

surpass the best Peruvian guano."

That desideratum, Professor Mapes believes he has already attained by

the addition of superphosphate of lime to the Guano, making a compound

of two-thirds of the latter to one of the former, more valuable by

weight than the pure article. That being the case will greatly increase

the consumption of Guano, and greatly improve the condition of all that

class of farmers who desire to make their poor lands rich.

Of the use of lime, Mr. Newton has the following testimony, which we

embody here for its great practical value.

"Calcareous matter is the great want of most of our lands, and in some

form is essential to permanent improvement. It should be regarded as the

basis of all our operations, and never to be dispensed with for any

substitute. From long experience in the use of lime, I am satisfied that

the French plan, of light and frequent dressings, is not only much more

economical, but much safer, in our climate, than the heavy dressings

common in Great Britain. Fifty bushels of slaked lime to the acre, I

have found amply sufficient for any of our lands, and a greater quantity

often attended with injury to the soil and crops, whilst twenty-five

bushels will answer every purpose on thin lands, deficient in vegetable

matter. Ashes, bone dust, and the various marine manures that abound on

the shores of the Chesapeake and its tributaries, will be found

important auxiliaries in the work of 'keeping your lands rich,' whilst

the necessity of clover and the proper grasses, to any system of

permanent improvement, is too obvious to require comment."

Although caustic lime should never be used in connection, or so as to

come in contact with the Guano, there is no doubt of its being a

valuable auxiliary. Upon land limed this year, Guano may be used next,

and if mixed with charcoal or plaster, or plowed in and thoroughly

incorporated with the soil, especially if it contains a considerable

portion of clay, no loss of ammonia will occur, in consequence of the

action of the lime. On the contrary, the effect will be to make the

action of the Guano more active, and the immediate benefit greater;

though, of course the succeeding crops would not receive as great a

share. But, as Mr. Newton says, ought we to ask for great advantages to

succeeding crops, from a manure which gives us such great profits from

the present one.

From our notes taken upon the spot, we give a few items more in detail

of Mr. Newton's operations, than he has done in the preceding

quotations. The tract of land he speaks of is gently undulating; of a

sandy loam, with a greater amount of clay in the subsoil; had been

literally _worn out_ in former years by the shallow plowing, skinning

system of farming, until it would produce no more, when it was abandoned

and suffered to grow up again in forest timber, principally pine of the

"old field" species. No land could offer less inducements to the

cultivator or give smaller hope of renovation, than these old fields of

Virginia. Such was the conviction of impossibility to raise a crop upon

this kind of land, that Mr. Newton's first essay was looked upon by his

neighbors with a conviction that the fool and his money would soon part

company. One sensible old servant told us he thought his master "for

sartain was done gone crazy, cause he nebber seed no nothing grow on dat

land, no how could fix him." The negroes, wherever guano has been

introduced, have been violently opposed to using it; not alone from its

disagreeable odor and effect upon the throat and nostrils while handling

it in a dry state; but because they could not be persuaded that such a

small measure of stuff--200 lbs. measures about three bushels--could

possibly produce any effect upon the crop. Their astonishment and

consequent extravagant laudation of the effect produced, has often

afforded us hours of amusement while listening to their recital of

"massa's big crop," of perhaps ten bushels to the acre, which was at

least double that of any one ever seen upon the same field, "fore he put

dem little pinch of snuff on him."

_The increase of wheat from guano_ may be safely calculated upon at five

bushels for each hundred weight of guano used, one year with another,

and up to what may be considered a fair judicious amount to be applied,

which may be set down at an average of 200 lbs to the acre, upon all

light soils, similar to those of that part of the country we are writing

about.

GUANO vs. MANURE--EFFECTS UPON HEAVY LAND.

Mr. Newton related to us an anecdote of some value upon this point. On

one of his Potomac farms, a portion of the land is exceedingly

heavy--pewtery land, as it is termed from its tendency when wet to run

together, presenting a glistening appearance somewhat resembling that

metal. His overseer was about as unbelieving as the negroes, and

declared he could beat the guano by expending the same value in manure

upon a given quantity of surface. To test this and also to try its

effect upon the stiff land, he applied a little short of one ton of

Peruvian, which cost $50 upon ten acres, and promised a premium to the

overseer if he could make a greater crop by the use of all the manure,

men and teams he saw fit to apply to another ten acres lying right along

side, and of the same quality of soil. Of course he spared no labor,

using both lime and manure freely, but in the spring finding the

appearance of his crop unequal to that guanoed, he gave it a top

dressing of fine manure and a good working with the harrow. At harvest

the guanoed portion was ready for the sickle several days earlier than

the other, and yielded 135 bushels of a quality so very superior, it was

all reserved for seed for himself and neighbors.

The product of the other was 55 bushels; difference in favor of the

guano, 80 bushels--8 bushels to the acre--while the value of extra

manuring, probably exceeded the cost of guano, without any material

advantage in the effect upon succeeding crops. In fact, it is probable,

that the additional growth of straw and clover would be worth more to

the next crop on the guanoed portion, than the undecomposed manure and

lime would be in the other. It is needless to say both overseer and

servants, were fully convinced of the virtue of guano after this

experiment.

According to our notes, Mr. Newton first used guano in 1846--one ton of

Ichaboe at $30, on 8 acres, with 8 bushels of seed, upon land so deadly

poor, that an old negro we conversed with said; "him so done gone massa,

wouldn't grow poverty grass nuff to make hen's nest for dis nigger." No

attempt had been made for years to grow any crop, not even oats or rye,

the last effort of expiring nature to yield sustenance to man upon one

of those old worn out Virginia farms. Think of the astonishment of the

poor negro, who thought his master crazy to sow wheat there _without

manure_, to see 88 bushels harvested from the 8 acres.

In 1847, he used $100 worth of Patagonian upon same kind of land and

reaped 330 bushels. In 1848, $200 worth of Patagonian and Chilian at $40

and $30 a ton, gave 540 bushels, which sold at $1 25, mostly for seed,

on account of its superior quality. In each case the advantage to the

land of equal value as to the crop. In 1849, he applied 10 tons Peruvian

at $47, and 11 tons Patagonian at $30, upon 260 acres, from 75 to 250

lbs. to the acre. When we saw this crop the next spring, the appearance

in favor of the Peruvian, was fully 50 per cent. upon the same cost of

each kind per acre.

In 1850 he applied 30 tons, of course, all Peruvian, with equal success

to former years.

Mr. Newton says, the second application of guano to the same land

produces the best result--that notwithstanding the profit of the first

application in the increased crop, the profit to the land is always

greater.

Before leaving Mr. Newton, we will place on record one expression highly

creditable to him, and convincing in its palpable truth of the value put

upon this fertilizer, by a gentlemen of sound judgment and candor of

speech, equal to any other within the circle of our acquaintance.

"I look upon the introduction of guano and the success attending its

application to our barren lands, in the light of a special interposition

of Divine Providence, to save the northern neck of Virginia from

reverting entirely into its former state of wilderness and utter

desolation. Until the discovery of guano--more valuable to us than the

mines of California--I looked upon the possibility of renovating our

soil, of ever bringing it up to a point capable of producing

remunerating crops as utterly hopeless. Our up-lands were all worn out,

and our bottom lands fast failing, and if it had not been for guano, to

revive our last hope, a few years more and the whole country must have

been deserted by all who desired to increase their own wealth, or

advance the cause of civilization by a profitable cultivation of the

earth."

We are satisfied that the above opinion will be considered of more

value--more conclusive in favor of guano, by all who are acquainted with

the character of Willoughby Newton, than all else contained in the pages

of this pamphlet.
