Grasshopper Control in the Pacific States. rf 
RESULTS TO BE EXPECTED. 
Under the most favorable conditions large numbers of grasshop- 
pers have been killed as early as eight hours after the poison was 
spread in the fields, but usually the maximum number of dead hop- 
pers will be noticed two or three days later. These may be found 
under clods or weeds and in the crowns of alfalfa plants. The 
poisoned grasshoppers are eaten by other grasshoppers, beetles, and 
ants, in which the poison is again effective. 
DANGER OF POISONING LIVE STOCK. 
After the poison has been finely and properly spread over the 
fields at the rate of 25 pounds of dry wheat bran to 5 acres, there

is no danger of poisoning live stock. The danger hes in preparing 
and keeping this attractive mixture around the farmyard where 
poultry and live stock are present and might eat quantities of it; also 
in spreading it by handfuls or lumps over the field. It is advisable 
to keep poultry penned up for a few days after spreading the poison ; 
or to feed them well in the morning if they are to run at large where 
the poison is being spread, so that they will not pick up too many of 
the poisoned grasshoppers. 
DESTROYING EGGS BY CULTIVATION. 
Grasshoppers deposit their eggs in the soil, frequently at the 
bases of plants with bushy crowns. The abdomen is worked into
