STATE BOARD OF AGRICULTURE. 



north of the President's house, after wheat of the previous year. This may 

 liave had an iullueuce ou their work for this year, and made them worse ou 

 that particuhir ])iece of ground. Wlieat was sown after wheat in order to 

 work and smooth the ground more, preparatory to seeding it down in meadow 

 or hiwn. 



I liave compiled the following table of work of the Hessian lly, from ob- 

 servations conducted myself or under my immediate supervision. The first 

 column shows the per cent destroyed as observed and computed Nov. 25, 1877. 



The second and third colums show the number of larva? found in 30 stalks 

 selected from tliree different places in each plat, as observed June 14, and some 

 that were duplicated on June 2G. 



As a general observation, we might say that the ground on which these plats 

 of grain were situated was much too poor, and entirely unfitted for best results 

 in wheat raising : 



* Very good, t Very few heads. 1| Two observiitions. §Poor. 1[ Very lew heads. 



The inference cannot be drawn from the foregoing that some varieties are 

 insect proof or nearly so. We can infer that where there are several varieties 

 of wheat growing side by side, some varieties seem to l^e i)rcferred to others. 



The last three varieties mentioned in the table, were sown October 25, too 

 late for the work of the fall brood of Hessian fly. 



It has been very interesting to watch the development of these varieties and 

 see how thev have conducted themselves under the ordeal.
