MOLE DRAINING.
We hear of an implement, in use in Illinois and other Western States, called the Gopher Plow, worked by a capstan, which drains wet land by merely drawing through it an iron shoe, at about two and a half feet in depth, without the use of any foreign substance.
We hear reports of a mole plow, in use in the same State, known by the name of Marcus and Emerson's Patent Subsoiler, with which, an informant says, drains are made also in the manner above named. This machine is worked by a windlass power, by a horse or yoke of oxen, and the price charged is twenty-eight cents a rod for the work. These machines are, from description, modifications of the English Mole Plow, an implement long ago known and used in Great Britain.
