treatment are known, along with explicit directions for the application of such meas- 
ures. That the enforcement of such laws he made to rest upon some local authority 
and a provision that no person can enforce it against another unless he can show 
conclusively that he has himself carried out the intent of the act upon his own prem- 
ises. That said committee shall examine and report upon the desirability of intro- 
ducing more instruction in entomology in public schools or means by which to secure 
better information among the people regarding habits and importance of insects.

On motion of Mr. Southwick the report was accepted, and on motion 
of Mr. Smith it was ordered printed, so that an opportunity might be 
afforded members to examine it carefully and act on its adoption at the 
meeting of next year. 
The President read a letter from Miss Eleanor A. Ormerod, express- 
ing her regret that she was unable to be present at the meeting and 
take part in the discussions. 
The following paper by Mr. J. M. Aldrich was read, in the absence of 
the author, by Mr. Davis : 
SPRAYING WITHOUT A PUMP— PRELIMINARY NOTICE. 
By J. M. Aldrich, Moscow, Idaho. 
We are indebted to Prof. Goff, of Wisconsin, for the demonstration 
of the fact that kerosene may be so mixed with water at the instant of 
passing through the nozzle that the making of kerosene emulsion is 
thereby superseded. His appliance for mixing is so arranged that the 
suction of the piston stroke draws on both the water and the kerosene 
supply, the latter being partially cut off by a stopcock to mingle the 
two fluids in the correct proportions. The kerosene undoubtedly 
remains in large globules while passing to the nozzle, in going through 
which it is so finely divided and mixed with the water that its action 
upon insects and foliage is the same as that of kerosene emulsion. 
Another way of effecting the same result I would suggest, as follows : 
Taking the Nixon Climax nozzle as an example, the water, before strik- 
ing the screen, passes with great force through a small aperture. Let a 
small brass tube, connecting with the kerosene supply by a rubber 
extension, be introduced through the base of the nozzle and continued 
forward into the center of the before-mentioned aperture, which would 
have to be somewhat enlarged to still throw the same quantity of 
water. Now the action of the rapidly passing water will be to draw in 
the kerosene, and the result, I apprehend, will be the same as in the 
Goff method. In this case, however, water under pressure is all that 
is required; the nozzle does the rest. Hence, in cities and towns hav- 
ing municipal water supply this nozzle attached to the ordinary lawn-
