of many samples. The same results have been obtained in this
country by such eminent chemists as Professor Norton, Dr. Antisell, and
Dr. Higgins. We only give analysis of these three kinds, for the reason,
no other of any consequence is now offered for sale in this country.

It will readily be seen there is a vast difference in the value of the
Chilian, and though not stated, there is as great a difference in the
Patagonian, while that from Peru, owing to the fact that it never rains
upon the depository, is of a uniform quality. As the principal value of
guano consists of the ammonia and phosphates, it is easily calculated.

17 per cent. of ammonia is equal to 340 lbs. in
a ton of 2,000 at 12-1/2 cents, $42.50

23.48 per cent. of phosphates is equal to 470 lbs.
in a ton at 1-1/2 cents, 7.05

Alkaline salts, 5.00

Value of a ton of Peruvian guano, $54.55

To this may be added the advantage of having these valuable substances
in the best possible condition, so finely pulverized they are ready
prepared for the use of plants.

It may be taken as an incontrovertible fact then, that guano is a cheap
and good manure for any land and any crop which would be benefitted by
the best quality of farm yard manure and ground bones. It is most
beneficial on poor sandy loam, absolutely unproductive; and most
profitable when applied to any land which cannot be otherwise manured on
account of distance and transportation of grosser articles. The better
the land is
