Prepared Guano--Agricultural Salts--Generators and Regenerators._--Of
these, the testimony of Mr. Reynolds is exactly to the point, concise
and strong, and exactly in accordance with all the facts we have been
able to collect upon the same subject. He says, "I have tried them on
corn, wheat, oats, clover and tobacco; but have yet to discover that
they ever generated anything for me, though I have heard them sometimes
well spoken of."

Want of room in this pamphlet alone prevents us from inserting the names
and operations of many other gentlemen in this rapidly improving
State--a State now undergoing the process of renovation by the use of
guano, to a greater extent, perhaps, than any other in the Union.

GUANO IN DELAWARE.

_Hon. John M. Clayton's Farm._--No one who looks upon this highly
improved farm now, with its most luxuriant crops, can be made to believe
it was a barren waste seven years ago--hardly worth fencing or
cultivating. This great change, so far beyond the power of human belief,
has been effected by lime, plaster and guano. The railroad from
Frenchtown to New Castle, passes through this farm, four miles from the
latter place. It is well worthy a visit from any one anxious to make
personal observations of the effects of "bought manures," upon a soil
too poor to support a goose per acre.

_Effect of Guano on Oats._--During a visit to Mr. Clayton, in 1851, we
saw the most luxuriant growth of oats upon one of the fields of this
farm, which we have ever witnessed, and it has been our fortune to see
some tall specimens of this crop on the bottom lands of Ohio, Indiana,
and Illinois. The seed he had obtained from England, and the means of
making it grow, from Peru. The guano was plowed in with the oats, at the
rate of 350 lbs. to the acre. The soil is a yellow clayey loam. The
effect upon other crops had been equally beneficial. The growth of
clover was so great he had purchased thirty bullocks to fatten, for the
purpose of trying to consume some of his surplus feed. The effect upon
wheat, corn, potatoes, turnips, garden vegetables and fruit trees, was
almost as astonishing as upon the oats and grass.

_C. P. Holcomb_, Esq., one of the most improving farmers of one of the
most improving counties in the U.S., has met with great success in the
use of lime, plaster, and guano. His beautiful highly improved home farm
is near Newcastle; but that upon which he has met with great success in
the use of guano, lie
