Maize or Indian Corn being now cultivated to some extent in different parts of this country, we have given the engraving on the following page of a machine for husking the corn, or separating the grains from the ear, a process equivalent to that of thrashing employed for other grain, a is a crank handle or winch, which being turned, gives motion to a spur wheel b, and thereby causes a rapid revolution of the pinion c, on the shaft of which is fixed a large circular cast-iron plate d, the face of which is studded all over with very numerous cast-iron teeth or knobs; e is the hopper of the figure of a narrow inverted quadrangular pyramid; it has one of its sides movable, and capable of a very simple adjustment by turning as a lever upon a fulcrum at g, by which movement the aperture of discharge is enlarged or contracted; and it should be so regulated as only to admit of the central stalks of the cobs of the Indian corn to pass; these differ in size according to the fertility of the soil, the climate, and the treatment of the plant At h there is a curved slot mortise through the side of the hopper, through which the stem of a thumb-screw passes from the outside into the movable plate, which is confined in any position at pleasure by half a turn of the screw.

In America, where these machines are common, they are usually worked by one person turning the winch a, which gives very rapid revolutions to the plate d, whilst a boy drops one by one the cobs of Indian corn into the hopper, which causes each cob successively to spin round upon its axis, or stalk with great velocity, rubbing or knocking out the grain in its progress; and so effectual is the process, that a single turn of the winch a completely husks a large cob of maize.
