The Agriculture of America has seemed to me to demand some light upon the subject of Drainage; some work, which, with an exposition of the various theories, should give the simplest details of the practice, of draining land. This treatise is an attempt to answer that demand, and to give to the farmers of our country, at the same time, enough of scientific principles to satisfy intelligent inquiry, and plain and full directions for executing work in the field, according to the best known rules.
