PULVERIZING. 187 



tooth in front for a steering pivot ; a small plow-shaped tooth at 

 each side, which may be made to run very close to the row, as 

 it throws the earth from it ; and a broad V-shaped, knifelike 

 blade at the rear, ending in a rising comb. The knife edge cuts 

 off all weeds about an inch below the surface, and has sufficient 

 bend to throw back, toward the row, the earth that the wing plow 

 draws from it — leaving it very loose and fine. 



The intention of the rising comb at the back is to leave the 

 weeds on the surface, allowing the earth to fall through the spaces. 

 I never could see that this part of the programme was carried out ; 

 but, notwithstanding this, it is a capital tool, and, with the small 

 subsoiler for the earlier work, is all that could be desired for small- 

 sized fields.

 tool, which is better for hard or rough land than the one de- 

 scribed above, and for all work it is a good tool. 



Aliens horse-hoe (Fig. lOo) is essentially the same tool attached 

 to the under side of a pair of shafts (or thills) — which project far 

 enough to the rear to serve as handles. The rake at the back, 

 for weeds, is dispensed with, and the guiding tooth in front is not 

 needed, as the horse keeps the implement in place. It is claimed 

 that it works more truly, as to direction, than without the shafts. 



An implement similar to this, but without the V-shaped 

 knife at the back, and with larger plow wings at the sides, is an 

 excellent ridging tool for cotton land, or a furrower for potato 

 planting. After the potatoes have been planted, the same tool,
