On a Hill-side Plough. 17 



Mr. Randolph has contrived also, for our steepest hill- 

 sides, a simple plough which throws the furrows always 

 down hilL It is made with two wings welded to the 

 same bar, with their planes at a right-angle to each 

 other. The point and the heel of the bar are formed into 

 pivots, and the bar becomes an axis, by turning which, 

 either wing may be laid on the ground, and the other 

 then standing vertically, acts as a mould board. The 

 right-angle between them however, is filled with a slop- 

 ing piece of wood, leaving only a cutting margin of each 

 wing naked, and aiding in the office of raising the sod 

 gradually, while the declivity of the hill facilitates it's 

 falling over. The change of the position of the share at 

 the end of each furrow is effected in a moment by with- 

 drawing and replacing a pin. The little paper model en- 

 closed may help out my description of the share/ 



Thomas Jefferson.
