stances in guano as are Of value to agricutur-
lists, the following is an average Of the pro-
portion contained in Chinca guano.
Ammonia 1850 per cent
Soluble phosphoric acid 500
Insoluble $40
Potash, 354
The same average taken from several car
goes of Guanape guano imported in the
United States has been found to be,
Ammonia, 1873 per cent.
Soluble phosphorie acid, GO d"
Insoluble 90
Potash, 3.Sl
It has been ascertaned by careful enquiry
into this subject that in the United States,
the price Of the above named substances,
when obtainable in proper and fit condition
for manuring purposes, such for instance as
they exist in Peruvian guauo, may be set
down as follows
Ammonia, 243c per h.
Soluble phOsphoric acid, l6ic
Insouble &c "
POTASH, &c
BY this standard are fertilizers in your
market at present valued by chemists after
analysis. And when they report that fer
tlizer is Of such value per ton, it means
that the ton contains quantities of the above
named substances, which, estimated at the
established prices, will in the aggregate
amount to the value of the fertilizer
Yalueing the average sample of Chinca
guano by the same rule, the ton of 2,240
pounds will be worth 1927 .63c., which at
III per cent, the present price of gold, would
be equivalent to SLABS, gold
Proceeding in the same manner with re-
gard to the sample of Guanape the price of
2240 lbs. would be sl07 Gs currency, or at
Ill pr. ct. for gold, the value would be s97
90 gold
According to the price established by the
Government of Peru for guano in the United
States, Chincha can be purchased for, per
ton of 224O lbs, s67 80 3D.

With regard to Guanape guano, the prize
per ton is, as sold, $50 90 cd.
Value as per estimate % 90

BY the preceding comparisons it is show
that when purchasing Chincha guano, if tn
quality be a fair average the farmer obtain
the ingredients it contains, useful for manur
ing purposes, at about 4 pr ct. under th
cost as compared with the price of the sam
substances, when purchased in a fertiize
that would be reported, after chemical analy
sis, to be fully worth its selling price.
So also with regard to Guanape guano
the difference between the selling price AIT
the estimated value of this fertilizer consider
ably in favor of the purchaser. True hay
taken the wholesale prices in the comparison
above established, and the farmer may nc
always be able to purchase guano at thes
rates, as it is not so sold in small quantitie,
but it will be seen that the dealer on retail
might charge so, or even GO per cent. owe
the price paid for guano purchased by whole
sale, and yet the farmer would not be payin
Tor the fertilizing substances price in exces
OF their worth, as established by valuation.
In 1850, previous to the war the col
sumption of guano during the year exceede
in the United States eighty thousand ton
which was chiefly used in the South |
1861 the expectation for that market wa
discontinued and not again resumed unit
1865. In the year 1869 nearly Fifty thor
sand tons were sold to agricullurists and
manufacturers of artificial manures but Il
demand seems somewhat to have fallen off.
In Europe the quantity of guano annual
consumed being about 100000 tons, that
the United States is hardly 1.-THE of Il
former amount, which isl very small propo
ton indeed, considering the importance
the agricultural products Of the country,
In the year 1862, the Peruvian Cover
ment appointed commission composed
engineers, to measure the quantity of gual
existing in the Island of Peru to the Nor
of Callao.
AT the head of this commission was NJ
Joseph p. Davis, a gentleman whose mar
has subsequently, become we'll known in Il
country in connection with several importa
engineering works They surveyed and c
amined several islands and estimated t
quantity of guano on them respectively,
