PULVERIZING. 189 



back teeth alternate along the bar, so that every inch of the 

 ground is pulverized. By bearing on the front or back row of 

 teeth, (by lifting or bearing down on the handles,) slight inequali- 

 ties in the surface may be made smooth. 



The muUer is drawn by a single horse, the traces being attached 

 near the ends of the bar. It is more properly a harrow than a 

 cultivator, as it is too wide to be used between rows, although 

 a shorter tool of the same construction, with a steering rest behind, 

 would answer very well for this purpose. 



Whatever kind of horse-hoe or cultivator we may use, they 

 will usually be found profitable, in proportion to the frequency 

 and the depth of their use ; — the only qualification of this state- 

 ment being, that their vigorous use should cease after the side 

 roots of the crop have spread so as to occupy all or nearly all of 

 the ground between the rows.
