THE IRRIGATION AGE. 



The instrument may be rated by any of the stan- 

 dard methods and a table prepared for its use. As each 

 turn of the wheel is announced by a click .of the sound- 

 ing device, these clicks must be counted and timed. 

 This is easily done and answers the purpose very well, 

 but if desired, a better electric recording device could, 



POISONING CUT WORMS. 



A recent bulletin received from the Oklahoma Ex- 

 periment Station gives thefollowing mixture for poison- 

 ing cutworms. It says: 





Further experiments in poisoning cutworms, which 

 have been working on wheat and alfalfa, have shown the 

 following mixture to be superior to spraying with Paris 

 green, as formerly recommended: 



with a little ingenuity, be easily constructed. 



While this machine will not compare in accuracy 

 and durability with a standard high-priced current

Thoroughly mix, while dry, one pound of Paris 

 green and fifty pounds of wheat bran, make moist, but 

 not sloppy, by adding water in which a quart of cheap 



meter, the results obtained will be sufficiently reliable 

 for many practical purposes. No essentially new ideas 

 are embodied in its make-up. Its construction is the 

 result of the writers' regret that the high price of stan- 

 dard manufactured current meters forbids their use in 

 many instances where some kind of a meter could be 

 used to advantage, and a speculation as to the possi- 

 bility of evolving a "home-made" substitute. To the 

 consideration of these who may have shared in this 

 speculation and regret the above results are respectfully 

 submitted.

molasses has been dissolved. Place this mixture in 

 spoonful piles where the worms are working. It attracts 

 the worms from the wheat and oats. It is also good 

 grasshopper poison.
