THE COMPLETE GRAZIER. 



BOOK VIII. 



Unless the diameter of a roller is fairly large it does not turn easily, 

 and is liable to drive clods before it. There is much to be said in favour 

 of the hollow rollers which can be filled with water when weight is 

 required, and used empty for light work. These are made by Messrs.

Barford & Perkins, of Peterborough, and probably by some other 

 manufacturers. 



We present, in fig. 278, an engraving of another implement useful to 

 the farmer, the Beveiiey Iron and Waggon Company's Clod Crusher. 

 It is most valuable in crushing clods on heavy lands, and, when other 

 machines are useless, in dry weather.

The ring-roller, of which fig. 279 is an illustration, is useful for rolling 

 wheat in the spring. It may also be employed in the case of other 

 crops beneath which the soil is too loose, or which are affected by wire- 

 worm or other insects which attack the plant when young. It is like- 

 wise applicable as a clod crusher.
