 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-

 ducing more instruction in entomology in public schools or means liy wliich to secure 

 better information among the people regarding habits and importance of insects.

On motion of Mr. Soutliwick 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 sui^erseded. 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 i^artially 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 supjily this nozzle attached to the ordiimry lawn-
