It will be noted that tlie wheat grain is quite high in protein, fat, 

 and nitrogen-free extract, and thus highly nutritious, while the feed- 

 ing value of straw is quite low. These tables show the composition of 

 the ripened grain and straw only and reveal to us that at maturity 

 most of the nutritive value of the plant is collected in the grain, thus 

 rendering the straw of little value as forage. The tables also show 

 that of the nutrients left in the straw only a small percentage of them 

 is digestible. 



ENEMIES OF THE WHEAT CROP 



The Hessian fly is perhaps the most serious insect pest that attacks 

 wheat in this State. To offset its ravages it has been found advisable 

 to sow the crop a little late and after the first frost. There seems 

 to be no known practicable remedy for the prevention of rust, except 

 that of developing rust resistant varieties. Smut may be largely pre- 

 vented by treatment of the seed before sowing Avith a solution of 

 formalin. This is done by immersing the seed for thirty minutes in 

 a solution made of mixing one pound, or one pint, of formalin to fifty 

 gallons of water. Before treating with the formalin immerse the seed 

 in cold water and skim off any smut balls that may rise to the surface. 

 After immersion in the formalin solution, spread out the seed and 

 allow them to dry thoroughly before sowing. 



The insect enemies of stored wheat and oats may be destroyed by 

 the use of carbon bisulphide at the rate of 1 pound of carbon bisulphide 

 to 2,000 pounds of grain or 1,000 cubic feet of space. Put the grain 

 in a tight box and jjlace the insecticide in an open vessel on the grain 

 or near it and cover the box carefully. The fumes will go dovni among
