late the color of the young cotton bloom ; the catch-wings, the under side of the cover, 

 and the inside of the basin are to be of cotton-leaf green, and all other visible parts a 

 quiet earth-color; the lanterns are to be of such size and so disposed that one may be 

 readily sighted and sought from any direction within the field or approaching it. The 

 exterminator is to remain baited and posted day and night, the lamp to be lighted as 

 quietly as possible before twilight, and charged to surely burn the whole night 

 through ; its use to begin before the first moth of the season may be reasonably ex- 

 pected, and to continue till the last-belated straggler is surely gone. Operations, 

 however thorough, confined to a limited area, unless absolutely secluded, can give 

 only partial relief. 



To secure specimens of other "fly-by-nights," fit a wire gauze floor a little below 

 the rim of the basin, and place beneath it a sponge saturated with chloroform.
