KELLOGG: EXTRA-ENTOMOLOGICAL STUDIES

search training will already have been completed. He will now be in 
position to appreciate breadth of vision and inspiration in other fields. 
Above all things, let ns not in onr desire to build up large numbers in 
our own courses and in our own departments stand in the way of the 
proper breadth of equipment of the men on whom the future develop¬ 
ment of American entomology rests. 
Research in entomology has developed so enormously that there is no 
possibility of any one worker covering the entire field of knowledge, or 
any reason why he should try. Every student should, for example, 
have some fundamental work in entomological classification and for 
many lines a rather detailed excursion into the classification of one or 
two orders will be beneficial, but unless trained to be a museum assistant, 
the mastery of the entire classification would be a burden rather than a 
help—an encyclopedia rather than a text. Even if the student was 
training to be a systematist, an excursion into systematic work in other 
orders of the animal kingdom, and especially into the modern concept of 
bacterial and fungoid relationships would be much more helpful. Half 
of the time otherwise spent in this work could be employed with more 
profit in the broad fields of evolution, genetics and ecology or in even 
more distant fields where contact could be made with inspiring men. 
There is in my concept no possibility of laying out a postgraduate 
course for an individual unless you have first laid out the individual, 
that is, ascertained his aims, ambitions, and capacities. Stop for just a 
minute to consider the inspiration to zoological science of a man like 
Agassiz, not only in his generation but continuing down until the present 
to such an extent that today you can almost tell by listening to a man for 
a few minutes whether he was a student of Agassiz or even a student of 
one who was. The fundamental thing is to get inspiration into graduate 
work. Graduate training is not instruction, but inspiration,—training 
to think—to think clearly—and then, as Professor O’Kane suggests, he 
may be able to write clearly. 
EXTRA-ENTOMOLOGICAL STUDIES FOR THE YOUNG 
ENTOMOLOGIST 
By Vernon Kellogg, Washington, D. C. 
Abstract 
The more widely informed and the more soundly and broadly educated, the better 
the entomologist and the more effective he will be. The working economic entomolo¬ 
gist should have some basic training in general zoology and botany, systematic
