uniting forces with men of other professions who can cooperate with 
us. Thus the metallurgist, chemist, entomologist, and agriculturist 
make a fine combination. One needs a particular insect controlled, 
another finds out how to control it, the third finds how to make the 
substance, and the fourth extracts it from the raw materials. 
In the future we are going to have new series of insecticides. We 
are going to have insecticides which will conform more nearly to stand¬ 
ards. We are going to find out more accurately how insecticides kill, 
because it will be our business to make the most efficient killing sub¬ 
stances we can get. We will not put out substances that will kill the 
insect and also injure the plant or animal we want to protect, because 
we must continue to sell and the public will not buy unless we give 
results. 
Are we not naturally going to get greater progress in insect control 
when entomologists are in the ring trying to learn the very basic prin¬ 
ciples of control so that they will have the best product on the market? 
Can you not see the great stimulation which modern business is giving 
to research? The commercial research man is given definite practical 
problems to solve. He knows that when he solves them, they will be 
put into practise and commuted into the coin of the realm. He also 
knows that therg will be a suitable reward for his industry. 
Men are going to be in demand. But they must be men who are 
wide awake to the field. They must be men who are thinking about 
these things and studying to equip themselves for this great field of 
future investigations. More men must be trained. And the training 
of entomologists for practical life is quite different from the training 
for pure science. Our professors must begin to think out new courses 
of training, with practise as the dominant note. 
New insecticides acting along new principles will from time to time 
appear on the market and our colleagues in official positions will find 
they must give these fair tests. There must be open mindedness on 
both sides. We must have cooperation and fellowship in our science. 
If the official investigators need a particular substance put on the 
market in sufficient quantity and of proper quality at prices which 
will bring results, they will get results quickest through active coopera¬ 
tion with their professional brothers who are in a position to do this. 
The official worker has a problem to solve and wants to try many new 
substances but finds them difficult to obtain. If he calls in his pro¬ 
fessional colleague and asks his cooperation, between them they will 
get results. 
We can not insist too often on the necessity of forever relegating to 
the past the days of the selfish investigator who tries to do all his work 
alone so that no one else can participate in the credit. We have ar-
