he last cargoes being of little more value than rich earth. It is
said that a new deposit, which is nothing more than dry bird dung, has
already been gathered and taken to England. No doubt cargoes of similar
manure might gathered from the Florida keys; and although it would be a
valuable manure, it is not guano--that is formed by the chemical action
of a dry atmosphere, during time's long ages.

_Anagamos Guano._--This is also of a character similar to "new Ichaboe."
It is rich in ammonia, but contains no lime or sulphuric acid, and less
phosphates and alkaline substances than Peruvian, and more sand. The
supply of this must be very limited, as it is a recent deposit and has
to be gathered by hand from the rocks.

_Bolivian Guano._--This as its name indicates, is from the coast of
Bolivia, on the west side of South America. It was thought at one time
to be fully equal in value to Peruvian, but some subsequent importations
of almost worthless cargoes, have proved the deposit to be very variable
in quality, or else purposely adulterated, which has had the effect to
destroy confidence in all bearing that name. The belief of the writer
is, that it was not adulterated, but owing to the fact that it is found
in a latitude where it does sometimes rain, or where it is liable to be
drenched by sea spray, that portions of it are injured in that way; so
that a ship may have one portion of her cargo of the best kind, while
the remainder is hardly worth the freight. The deposit is not large.

_Chilian Guano._--The most of that imported into this country under this
name, has been of a very inferior quality, and having been recommended
by those interested in its sale, as having come from the same coast as
that of Peru, and of equal value, and proving almost worthless, has
deterred many from making another trial. Although there is a small
supply of Chilian Guano, which is gathered from the rocks in pale yellow
masses, some of which has been sent to England and this country, which
is equal to any ever discovered in any part of the world, yet the great
bulk of the deposit is so inferior that Chilian guano will never meet
with universal favor. In fact, some of the stuff which has been sold
under that name, is unworthy to be called guano.

_Patagonian Guano._--Of this kind, larger quantities have been imported
than any other beside Peruvian; and it has generally been sold at higher
prices than its value as a fertilizer would warrant. Ow
