purposes. A plow with a moklboard possessing a 

 short abrupt curvature is generally held to be the 

 most valuable for dry-farm purposes, since it pul- 

 verizes the soil most thoroughly, and in dry-farming 

 it is n(jt so important to turn the soil over as to 

 crumble and loosen it thoroughly. The various plow 

 bottoms are sh(jwn in Figure 7."). Naturally, since 

 the areas of dry-farms are very large, the sulk}' or 

 riding pl(.)W is the only kind to be used. The same 

 may be said of all other dry-farm implements. As 

 far as possible, the}^ should be of the riding kind, 

 since in the end it means economy from the resulting 

 saving of energy. (See kig. 74.)
