1 is a perspective view of the trap ; 2 is a central vertical section of

The trap is constructed of a frame, A, similar to that used ordinarily in ll:it->idt-d 

 lanterns, and in substantially the same manner, and may lr square or otherwise poly-

 constructed of stationary slats, a (which should be made of tin or other bright metal), 

 placed horizontally parallel to each other, at a downward inclination of about fifty 

 degrees, so that the lower edge of each slat a shall fall below a horizontal plane ex-
