good seed becomes the tirst requisite in securing the healthy, vigorous 

 phmt that is to be further strengthened and ^ustained b}' a well- 

 prepared, fertile soil. It is ver\- clear, then, that all shrunken, 

 dwarfed, or otherwise imperfect kernels should be cleaned out of the 

 seed before it is sown and only the largest and most perfect retained. 



CONCLUSION. 



Methods for controlling the Hessian tiy. the worst pest of the wheat 

 field, in the fall wheat growing sections, may be summarized as fol- 

 lows: Sow the best of seed in thoroughly prepared, fertile soil after 

 the major portion of the fall brood has made its appearance and passed 

 out of existence, and. if possible, sow on ground not devoted to wheat 

 the preceding year. 



In the spring-wheat section late seeding will not apply. It seems 

 likely, on the contrary, that the earlier it is sown in spring the less it 

 will suffer from the Hessian fly. But good seed and a well-prepared, 

 fertile soil are as essential there as elsewhere.
