 over the fame fpot. 



It equally excels as a drag, or firft harrow, for 

 rough land commonly ploughed ; and alfo for fuch 

 as is turned one half on the other, which we call 

 fkirring or thwarting, as well as for finilhing and 

 fmoothing the furface. 



I imagined at firft more ftrength would be re- 

 quired to draw it, but find two of our little country 

 horfes from 14 to 141 hands high, draw it with eafe. 



My harrow is feven feet one inch long, and the 

 pods twelve inches from center to center. The 

 bolts mould be forelock'd on top, and have a fmall 

 flat head under \ The pods are 3 by %\ inches, the 

 ledges or bars are three inches by 3-qrs. of an inch, 

 which was intended for a finilhing or laft harrow, 

 not a drag.
