108 INSECT PESTS OF FARM, GARDEN AND ORCHARD 



high at the back and an inch high in front. A runner at each 

 end, extending some distance behind, and a cord attached to each 

 front corner, complete the pan. We have known of from seven 

 to ten bushels of young locusts caught with one such pan in an 

 afternoon. It is easily pulled by two boys, and by running 

 several together in a row, one boy to each rope, and one to each 

 contiguous pair, the best work is performed with the least labor." 

 Larger pans are drawn or pushed by horses. The oil is best 

 used on the surface of water, from which the insects are removed 

 with a strainer, and any which hop out will die after having come 

 in contact with the oil.

are caught, so many will remain that the damage done the 

 crops would be but very slightly diminished. One of the most 

 promising means for preventing the swarms of winged migratory 

 locusts from alighting in the fields is by a dense smudge, in 

 which some foul-smelling substances are placed. Where strictly 

 attended, and with favorable winds, this has often proved highly 

 successful. To accomplish the best results farmers over an 

 extensive area should combine in its use.
