430&#93; 3°] HAR 1 -1 7 2 3 5 6 p 10 12 13 11 B 14 The design of this implement is to clear turnips from weeds, &c< Each share is about 14 inches dis- tant,and, when the harrow- plough moves forward, the shares marked I. 4, ", are the first, each of whicii cuts the plants' or weeds in its way. These are succeeded by others marked 2, 3, 5, and 6, which to- gether form seven shares. The seven remaining behind are intend- ed to complete the work com- menced by the first row. Thus each share clears about 8 inches of land in width, and leaves the space of 6 inches untouched.

Hence Mr. Kxight has contrived two joints, A, A, in the axle-tree, one of which in the subjoined cut igii t3 is covered, in the same manner as construction of the joint. There the harrows are at work: are also two joints, «,«, in the front the other h uncouued, to shew the of the bar, by means of which, from
