line will be | of an inch above it; or it may lie otherwise stated, 

 that the sole of the land slopes upward and forward, and the 

 sole of the share slopes upward and backward to the point of 

 their junction. The object of giving it this concavity is to 

 diminish friction and to give dip or eartliAvard tendency at all 

 times, together with steadiness of motion. The land side is 

 inclined vertically inward, so tliat at 12 inches al)ove the sole it 

 inclines 1^ inches from the perpendicular. The front standard, 

 A, is cast in the same piece with the land-side plate; its front face 

 forms a continuous curve with the breast, its radius g-rowin^ 

 smaller as it rises, until at length the line of the curve moves 

 forward. It is flat on the land side and convex on the furrow 

 side. It is cast hollow, which permits a bolt to pass vertically 

 through it, its head being on the under side and a nut which 

 screws on the upper surface of the beam. It is 3 inches wide 

 and li inches thick. Its upper termination is in a plate, a, 6 

 inches long and nearly as broad as the beam which rests upon it. 

 The rear standard is cast in the same piece with the land side 

 plate, and is provided with flanges at its upper end, which 

 receives the lower ends of the handles, as described above. 



We give the annexed cut (Fig. 115) of the front and rear 

 standard, A and B; a and b are the flanges upon which the beam 

 rests; c and d the flanges which support the handles. D, the
