HINTS FOR THE PROMOTION OF ECONOMIC ENTOMOLOGY. 719 
according to the particular indication of the case; and the trans- 
portation of parasites known to affect the pest in other localities.* 
In the last annual report of Mr. C. V. Riley, Missouri state en- 
tomologist, there is a very effective comparison of the ravages 
made by the gregarious insect pests with the destruction caused by 
an invading army. The same simile has been frequently used by 
me in conversation, and has doubtless often occurred to many of 
you. The application of it made by Mr. Riley is that, if an en- 
emy were to cause a small fraction of the injury which results each 
year from the depredations of even one of several of our insect 
enemies, the whole country would resound with a clamor for the 
suppression of the invaders. The memory of a colossal conflict 
is, alas! still fresh in our minds, and I desire not to awaken the 
painful recollections which rest in the bosoms of us all; but 
leaving out reference to the distressing scenes which we have all 
witnessed, there was much of the ludicrous, from which we may 
on this occasion derive profit, or at least the material for carrying 
our simile somewhat farther. 
Putting out of view for the moment the noble patriotism of the 
uncorrupted and incorruptible masses of our nation, prominent 
among whom were the great agricultural class, whose interests it 
is the object of the present inquiry to protect, we all remember 
vividly the eager struggle of small politicians for staff appoint- 
ments, of greater politicians, innocent of martial training, for 
higher commands ; the zeal of contractors to furnish supplies for 
the soldiers in the field (sometimes, as in the case of shaving soled 
shoes, and shoddy garments, rather aggravating than relieving their 
sufferings) ; the general hurry and scurry, and bustle and turmoil, 
to do everything hastily and with the greatest pecuniary profit. 
Why was all this? Was the great glory to be obtained in mili- 
tary service, when man fights man, the stimulus? Is there not 
equal glory in the more laborious, albeit peaceful combats of sci- 
ence, when man subdues the inorganic or the organic powers which 
resist his will, and make them subject to his control? Or is it, per- 
haps, to use a common phrase of the period, because there was 
money in it? 
*I learn from t bent oe annual report of Dr. W. LeBaron 
that in accordan h ideas first published by Mr. B. D. Walsh, a Chaieidosas par 
ite of a coccus, igor attacks the apple tree, has probably been successfully int 
duced into the northern part of the state, where it was previously unknown.
