To Save a Valuable Crop When Hoppers Are First Hatching: 



Let us suppose that a farmer who has a fine stand of grain, or other 

 crops, notes during the early summer that very small hoppers, just 

 hatched, are appearing in enormous numbers in a pasture adjoining, 

 or near his wheat field. He is alarmed, and reasonably so, for the 

 safety of his near-by crop. The method of procedure in this case is 

 to plow the dangerous field where the hoppers are hatching, beginning: 

 at the extreme edge and working toward the center. This buries- 

 many of the pests, and, by turning the grass under, starves nearly or 

 quite all of the others before they arc able to reach the edge of the 

 treated field. 



Placing a strip of plowed land between a crop and an advancing 

 army of quite young hoppers will sometimes turn their march and 

 prevent loss. Sowing a strip of rye around the edge of a wheat field 

 is claimed to be a simple way to keep grasshoppers at the edge of the 

 field. The rye grows more rapidly than the wheat, and will stand much 

 "eating down." This keeps the locusts in a comparatively narrow 

 area where they can be. easily handled. It may be said here that the 

 method of letting the land lie fallow encourages the grasshopper evil.

The accompanying cuts illustrate very well the structure and 

 method of using hopperdozers. They are made of sheet iron or 

 gah^anized iron. The front edgt^ of the liorizontal portion is turned 

 up about two inches. The corners are riveter!. U^on the rear is 

 attached vertically a light wooden frame, which is later covered with 

 canvas. An ordinary sized hopperdozer is al)out eight feet long, 

 and before the above mentioned wooden frame is attached resembles 

 a shallow pan. Runners (about three to a dozer), turned up slightly 

 in front, are cnidely made of ])ieces of sapling or board. The front 

 ends of these are fastened to a crosspiece, to each end of which rope 

 is attached. These ropes in front are fastened to a single-tree. The 

 ]jan may or may not be divided into compartments, the latter prevent- 

 ing in a measure the swashing about and loss of the liquid, and are 

 particularly desirable on uneven ground.
