kept in tilth, the better will be the effect of an
application of guano. The public may also be assured of another fact; if
the guano is bought direct from the agents of the Peruvian government in
this country, or of reliable merchants, who get their supplies direct
from them, it will be of a uniform quality and value, as indicated by
the analysis just given.

They may also rest assured, and the author of this pamphlet believes his
reputation will warrant the assertion and belief, that he could not be
hired to puff an unworthy article, or write a book to induce American
farmers, to purchase an article which would not prove highly beneficial
to their best interests.

The author does know that the introduction of guano into this country is
a blessing to the nation. Its general use will not only increase the
wealth of individuals, but that of the body politic. Let us illustrate
this point by a statement of an English writer of its advantages to that
country. He says--"The importance of this question may be easily
illustrated. We grow in this country about 4,000,000 acres of wheat
annually. An application of two hundred weight of guano to each acre
would increase the produce by six bushels, or raise the average of
England from 26 to 32 bushels an acre, giving a total increase to our
home produce of 3,000,000 quarters of wheat, which is of itself
equivalent to a larger sum than the whole diminution of rent stated by
the Chancellor of the Exchequer to have been occasioned by free trade in
corn. But this is only one use to which guano would be applied, for its
effects are even more valuable to green crops than to corn."

The proportionate advantage to this country would be almost
inconceivably greater as our average product is far less, and the
increased number of bushels per acre, far more; the produce of land as
stated by Mr. Newton and others, having been raised from 3 to 15 or 20
bushels per acre.

The estimation in which it is held by some of the best farmers in the
world may be judged by the increased demand in England.

The quantity of Peruvian guano annually imported has risen from 22,000
tons in 1846 to 95,000 tons in 1850, but has increased during the last
year to about 200,000 tons. If the price were reduced by L2 to L3 a ton,
even the present large supply would be found greatly short of the
increased demand. In a single season, in 1845, when the price of Ichaboe
guano ranged from 6L to 7L a-ton, the importati
