paper wadded down in the bottom of the bottle. This does veiy well 

 for a small bottle but one should be veiy careful to have bottles of thick

 bottle broken it should 

 be buried deeply in the 

 ground. Poison bottles 

 should not be left open 

 in the room nor left 

 where small cliildren 

 can get at them, and

 be impressed A\ath the 

 possible danger. It is 

 best that the teacher 

 should have all the bot-

 collecting trip. 



Specimens should not 

 remain in the poison 

 })ottle more than a day or two. In fact, insects \\'ith yellow mark- 

 ings should not be left in over night as the yellow will turn to red.
