ning of emergence of the flies in the spring to be then plowed 

 for some crop. This allows of seeding the wheat crop to grass 

 or clover in the late winter the year before and gives grazing 

 during the fall and early spring when otherwise because of 

 insufficient rainfall it might not be possible to secure any 

 profitable returns. 



The joint worm, according to official remedies discussed 

 in Farmers' Bulletin No. 1006, p. 12, is to be controlled by let 

 ting a stubble of about ten inches stand and plowing this down 

 deeply during the summer and early fall. With the ground 

 usually dry like a brick at this time, this is some job, however 

 a tractor might be said to do away with this difficulty. In any 

 case this with such a quantity of loose combustible matter 

 buried usually will cause this upper layer of soil by breaking 

 the capillary attraction at the d,epth of the plowing, anyway, 

 deeply, to dry out like a bone, in that case rendering it unlit 

 to grow anything before next spring. Moreover as it is best 

 of farm practice to sow wheat to clover and grass in late winter 

 and early spring, if this plan is followed we have a crop coming 

 on after the wheat is off, where otherwise we have but a pile 

 of trouble to bury the stubble. Why not then sow all the 

 wheat fields to clover and grass and then after leaving a stub- 

 ble of ten inches, go over with a mower, cutting close to the 

 "rornd, fitting the mower with an attachment to catch the clip- 

 pings. These clippings need not be burned. They could be 

 spread on some low ground where the water drains during the 

 winter. This excess, of moisture coupled with thf thawing 

 and freezing would kill the larvae or pupae within. The less
