to do so, while the three other sides enter into 

 the composition of the oblique, or slanting 

 mould-board, over-hanging behind, vertical 

 midway, and projecting forward. The angle

 foremost point of, or at, the land-side, is about 

 forty-two degrees, and the length of it, or, in 

 other words, of the first side, is eleven inches. 

 The line of the next, or the second side, is 

 nearly, but not exactly parallel with the before- 

 mentioned right-lined land-side, for it widens 

 or diverges from the angle at which the first 

 and second sides join towards its posterior or 

 hindermost point, as much as one inch. 

 Hence, the distance from the hindermost point 

 of the mould-board, at the angle of the second 

 and third sides, directly across to the land- 

 side, is one inch more than it is from the angle of 

 the first and second sides, directly across. The 

 length of this, the second side, is eight inches. 

 The next side, or what is here denominated
