 spiders, on the rafters the homes of the mud-wasps and th( 

 paper-wasps. In the clothes-press, perhaps, there are moths 



Under the carpets are the carpet 

 beetles. Flies and mosquitoes are 

 hard to keep out of the house 

 Ants invade the pantry. All these 

 creatures come into the house it

So there should be no difficulty in finding and coUeqt 

 ing insects for nature-study. For this purpose the pupil: 

 should be provided with nets. The older pupils can mak( 

 their own. An insect-net should be made of some light poroui 

 cloth, such as muslin, cheesecloth, or mosquito bar, made ir 

 the form of a sac about ten inches in diameter and abou 

 twice as long, fastened to a wire loop which is securely at 

 tached to a stick about four or five feet long. 1 1 



The dip-net may be smaller and should have 

 a finei mesh. It is emptied by turning it in- 

 side out. Aquatic insects, to be kept alive, 

 must be carried in water in pails or bottles. 

 Cans, paper boxes, and bottles serve to bring 

 back alive land insects for the school-room 

 cages. 



But if the insects are to be mounted, they are immediatel; 

 killed by placing them in the cyanide bottle. Each pupil ii 

 the higher grades should have one of these. Take a wide
