396 THE CANADIAN ENTOMOLOGIST 



will tell him of things that, though he may have spent a life time 

 in farming, neither the farmer nor his neighbours ha\e e\er yet 

 been able to observe. His caller not only fits into their farm life 

 and speaks to him in the language of the farmer, but is able to 

 explain, in a perfectly natural and intelligible way, much of what 

 to him has heretofore been a mystery. The young fnan points out 

 to him wherein their farm methods have, in many cases, been 

 primarily responsible for their previously sustained losses by insect 

 attack. The farmer is now in a position to read entomclogical 

 'iterature intelligently and with pleasure to himself. It does not 

 greatly matter of what State he may be a resident, if his locality is 

 not too inaccessible and the matter is of more than local importance 

 any of the men located at the fifteen different field stations can be 

 wired instructions that will send them to his relief. In this way 

 entomology as applied to the broad acres of the farm has within 

 the last twenty-five years become completely revolutionized. 

 This means much to the growers of grains and forage crops and to 

 the stock breeder. Moreover, it means almost equally as much to 

 the banker, the manufacturer, and the merchant, all of whom are 

 coming to recognize the fact. It has been my own practice to 

 take up only such investigations as involve several States, leaving 

 local matters to State institutions, where such are equipped for 

 the work, and, when called upon to deal with stich, I have urged 

 that the State be ac least given an opportunity to help itself, while 

 we stood ready to reinforce their etTorts if need be. This course 

 has beer followed especially with reference to local outbreaks of 

 grasshoppers. Where in\estigations can be carried out in any 

 State, as a part of an extended plan of work, notably that of wheat 

 sowing in fall to evade the fall attack of. Hessian fly, we have car- 

 ried out such experiments with the co-operation of farmers at 

 whatever points seemed most desirable for obtaining results which 

 would benefit the greatest number of farmers. In many cdses 

 these sowings have been also made in co-operation with State in- 

 stitutions. The alfalfa weevil investigations have been carried on 

 in co-operation with the State agricuKural college and station at 

 their request. 



Besides the field laboratories there are being carried on field 

 experiments, out on the farms, under precisely the same conditions
