If nothing more were taken into account than the aid in defending 
farmers against insect pests, the appropriations made by the different 
states for the support of such efforts could but be regarded as very 
profitable. More than this, the agencies devoted to investigation and 
teaching have constructive value in opening the way, slowly to be sure, 
for more effective methods of handling the vast agricultural resources 
of the country. For these reasons careful consideration should be 
given by entomologists to what are their real needs if their activities 
are to develop in accordance with the demands made upon them. 
Moreover, a proper balance should be maintained between such efforts 
as investigation, instruction and inspection that they may proceed 
symmetrically. The foregoing remarks serve to introduce the ques¬ 
tion if the work of inspection and certification of insecticides should 
not receive more serious attention by entomologists. There is no 
escape from the fact that the field of insecticides is being energetically 
exploited in an increasing degree, with the result that there is now an 
amazing assortment of spraying materials on the market. The enact¬ 
ment of measures providing for more complete analyses and clearer 
explanation of the data than is now done, should prove beneficial to 
both manufacturers and farmers. Also, with conservative inspection
