SANDERS: PRESIDENTIAL ADDRESS

out with the soil expert and the agronomist. Probably herein lies the 
greatest opportunity for cheap, valuable and reasonably constant pest 
control without serious interference with customary routine practice. 
The writer believes that preventive entomology, akin to preventive 
medicine, has an interesting development just ahead. 
The remarkable results obtained in heat control and vacuum fumi¬ 
gation of insect infested goods opens up a tremendous new field, which 
would indicate the desirability of intermittent heat storage to replace 
cold storage for household goods, woolens, furs, carpets, grain and grain 
products, tobacco, lumber and similar dry merchandise. Who knows 
what recent experiments in dusting by airplane may lead to, even to the 
extent of gas treatment of immense acreages. The recent development 
of liquid cyanogen for fumigation; the highly successful paradichloro- 
benzene treatment for peach tree borers; the greatly belated develop¬ 
ment of casein and flour stickers; copper-arsenic dust for potatoes, 
and similar crops, and the rapid adoption of the alkaloid nicotine in 
liquid and with a dust carrier, are a few outstanding recent accomplish¬ 
ments of which we can be proud. Every young entomologist should 
have an attitude of assurance to believe that economic entomology is 
only in its morning hours and that he has a wonderful opportunity to 
aid in turning on the light to a more perfect day of accomplishment. 
Whereas but a few workers labored in earlier years and accomplished 
so much in a brief span of activity, should we not be buoyantly opti¬ 
mistic with high expectations when many workers shall have merged 
the impetus of their endeavors in entomology and closely allied subjects. 
Past President Cooley: We have had the privilege of listening to 
a very thoughtful and interesting address. 
We will now proceed with the discussion. 
Mr. Wilmon Newell: It seems to me that we have received, in the 
President’s address, some good food for thought. We can well afford, 
in the haste of carrying out our own plans and ideas and purposes, to 
occasionally pause and give thought to just such considerations as have 
been brought out in that excellent address. Perhaps most of us do not 
stop to think what next year and the year after, and the next ten years, 
may bring forth, either in our own lines of endeavor or the endeavors 
of our fellow workers in economic entomology. No one could have 
foreseen, a quarter of a century ago, what has actually happened in the 
last twenty-five years, and of course no one can foresee what will happen
