Practical Considerations. 163 



pans or in saturated cloths, stretched on frames, drawn 

 over a field. A good and cheap pan is made of ordinary 

 sheet-iron, eight feet long, eleven inches wide at the 

 bottom, and turned up a foot high at the back and an inch 

 high at the front. A runner at each end, extending some 

 distance behind, and a cord attached to each front corner, 

 complete the pan, at a cost of about $1.50.

Small Coal-oil Pan. 



I have known 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 outer rope and one to each contiguous 

 pair, the best work is performed with the least labor. Heav- 

 ier or longer pans, to be drawn by horses, should have 

 transverse partitions to avoid spilling the liquid ; also more 

 runners. The oil may be used alone so as to just cover the 

 bottom, or on the surface of water, and the insects strained 

 through a wire ladle. When the insects are very small, 

 one may economize in kerosene by lining the pan with 

 saturated cloth ; but this becomes less efficient afterwards, 

 and frames of cloth saturated with oil do not equal the pans.
