The method of construction not only permits this imple- ment to break clods, but it is also well fitted to firm the loose surface and secure the proper texture for a first-class seed bed. The width of implements used varied from 8 to 12 feet. Four men in the Los Angeles and one each in the Oxnard and Salinas districts did this work with a tractor. ROLLING. BEFORE PLANTING. The type of roller employed in preparing the seed bed ranged from the smooth-drum roller, either wood or steel, to the clod crusher or " cross-kill" (see fig. 7), as it is commonly called. The cross-kill con- sists essentially of a series of narrow, toothed rings, attached to a shaft or axle. This implement not only breaks up clods and pul- verizes the soil, but also serves to pack loose soil. (See Table XI.).
