ant," by ROBERT THOMPSON; "Rogers's
Vegetable Cultivator;" and "Lawson's Agriculturist's Manual,"--I have
made liberal extracts; and lest, in the course of the volume, any
omission of authority may occur where it should have been accredited, my
indebtedness to the valuable publications above mentioned is here
candidly confessed.

In adapting directions for cultivation, prepared for one climate, or
section of country, to suit that of another quite dissimilar, so much
alteration of the original text has at times been found necessary, that
I have not felt at liberty to affix the name of the original writer, but
have simply added the usual marks denoting derivation of authority.
