152 On planting Indian Corn, 



position throughout the season, which affords, to the 

 roots of the corn, the best soil for nourishment, in 

 whatever direction they may be extended. 



At the season of big hilling (in the technical language 

 of Pennsylvania,) I give my corn a similar course, with 

 the same machine, but with small shovels, resembling 

 that of the shovel plough, introduced into the places 

 before occupied by the coulters, when the dressing is 

 ended. 



It remains only to give you some description of my 

 corn machine, and to state to you my reason for adopt- 

 ing this method of raising corn, and the consequent 

 advantages. 



The frame of my harrow is perhaps no way material- 

 ly different from that of the common triangle corn har- 

 row ; the sides about 44 feet long, with a spread that 

 places the two back teeth 42 inches apart : the whole 

 number of teeth is seven; the front tooth in the centre, 

 and the other three aside, at equal distances : a light 

 piece of scantling is framed into the sides, in front of the 

 back teeth, for the purpose of strengthening the frame 

 and supporting the handles. — The coulter tooth is 

 about 104^ or 11 inches below the timber, forming 

 such angle with the shank as to give the coulter that

 low the shank, is about six inches in length, and 4^^ in 

 breadth, projecting in that position best adapted for 

 cutting grass or weeds, and generally for cleaning and 

 mellowing the surface. The shanks of each are fitted 

 to the same hole and fastened with a screw on the top : 

 the coulter tooth must be supported with a consi-
