IMPROVED SULKY HARROW.
George M. Furman, Laclede, Mo.--This is an improved riding harrow,
so constructed that it may be readily raised from the ground, by the
driver from his seat, to clear it of rubbish, to pass obstructions,
and to pass from place to place, to cut up the ground and cover the
seed thoroughly, and be used for cultivating small grain and plants.
