recently, the investigation of ducks in rice fields is 370ur most im-

organizations and individuals at Sacramento and also witli Ltr. W. D. 
Bgilbert, Secretary, Rice Growers Association, Willows, California, 
for purpose of investigating the rice fields, botla there auid elsewhere 
at the time they report serious depredations. 5?he investigation should 
be carried on throughout the season. You can do quail investigation 
and other work of that character as opportunity offers. Experiments 
should be made by use of bombs and other devices, except poison, for 
pxirpose of control of ducks frequenting rice fields.
