greased the bottoms and sides with a little rancid butter, and placed 
them where the roaches were numerous. Each pan in the morning 
contained hundreds of the pests unable to climb out because of the 
greased sides. The roaches were shaken out into hot water, and the 
pans were again ready for use, without regreasing. 
Traps of the sort described above, placed in pantries and bakeries, 
will unquestionably destroy great quantities of roaches, and keep 
them in check and thus obviate the use of insect powders or the dis- 
tribution of poisoned baits.
