Report of the Judges. 229 



shoulder into which the share is titted and seemed by one bolt. 

 The standard, Fig. 116, H, is 10 inches high and 6 inches wide, 

 and, including the flange, which runs around the top and l)oth 

 sides, is 1 inch thick. It has an oblong opening, c, of 7 inches 

 by 2i, the sides of which are also ribbed. There are iive holes 

 on each side of this opening which permit a vertical range of six 

 inches to the sole of the share. The land side is a continuation 

 of the standard, and the breast is a continuation of its curve. 

 The length of the sole of the land side is 6| inches. The curve 

 of the mould-board differs from that of the plow. The tirst line, 

 coinciding with a straight edge, runs from the point of junction 

 between the share and land side at the breast back to a point on 

 the lower edge of the mould-board, "^-f^ inches above the plane of 

 the sole, which makes an angle with that plane of 6° 11'. The 

 upper line runs from a point on the upper edge of the mould- 

 board, 1\ inches above the sole, to a point in the rear edge, 8^ 

 inches above it, and makes an angle with it of AP 34'; the inter- 

 mediate lines vary in proportion. The vertical lines, in which a 

 straight edire coincides with the surface, varv more in their angles 

 with the tirst horizontal line than the lower share. Near the 

 standard this angle is 71°; the next towards the rear makes an 

 angle of 83°; the next, 85°; the next, 87°; the next, 91°; the 

 next, 97°, and the one nearest to the rear edge is 113°. 



Share. 



Length of the land side of the share, 4| inches; length of the 

 point, li inches; length of the feather, 9 inches; distance of angle 

 of feather from bottom of the mould-board, 2| inches. The 

 coulter is cast in the same piece with the share; it rises at an 

 angle of 43°, and is concave on its edge. The point is 1\ inches 

 l)road. The sole of the share and of the land side both slope 

 upward. A straight edge laid from the heel to the point forms 

 the base of a triangle Avhose apex is at the junction of the share 

 and land side, and whose height is i inch. The face of the 

 land side slopes towards the furrow side; at 4 inches above the 

 ])ase line it is ^ inch inward. The top of the coulter is \ of an 

 inch inward from the land side plane. The breadth from the 

 angle of the feather to the land side is 7| inches. 



We now come to the plow proper, or to those parts which are 

 directly concerned in turning over the furrow. These are the 

 share, the land side and the mould-board, with their attachments.
