Two-horse cultivators are very useful in pulverizing 

 the surface of inverted sod, and fitting it for the recep-

 is attached for lowering or raising the frame-work and 

 regulating the depth of the teeth. 



GarretVs Horse-hoe, an English invention, is a mod- 

 ification of the cultivator, and is used for cultivating 

 carrots and other root-crops in drills, cleaning eight or 

 ten rows at once. It is furnished with sharp horizon- 

 tal hlades, which run heneath the surface, and shave 

 off" and destroy all the weeds within an inch of the 

 rows of young plants. These rows, having been planted 

 by means of a drilling-machine, are straight and per- 

 fectly parallel, and the operator has only to watch one 

 row and guide the blades for that row, the apparatus 

 being so contrived that the blades for the other rows 

 shall run at the same distance from them.
