APPENDIX II 



REARING ANIMALS AND MAKING COLLEC- 

 TIONS 



Much good work in observing the behavior and life- 

 history of some kinds of animals can be done by keeping 

 them alive in the schoolroom under conditions simulating 

 those to which they are exposed in nature. The growth 

 and development of frogs and toads from egg to adult, as 

 well as their feeding habits and general behavior, can all 

 be observed in the schoolroom, as explained in Chapter 

 IX. Harmless snakes are easily kept in glass-covered 

 boxes; snails and slugs are contented dwellers indoors; 

 certain fish live well in small aquaria, and many other 

 familiar forms can be kept alive under observation for a 

 longer or shorter time. But from the ease with which 

 they are obtained and cared for, the inexpensiveness of 

 their live-cages, and the interesting character of their life- 

 history and general habits, insects are, of all animals, the 

 ones which specially commend themselves for the school- 

 room menagerie. In Chapters VIII and XIV are numerous 

 suggestions regarding the obtaining and care of certain 

 kinds of insects which may be reared and studied to ad- 

 vantage in the schoolroom. In the following paragraphs 

 are given directions for making the necessary live-cages 

 and aquaria for these insects. 



Live-cages and aquaria. Prof. J. H. Comstock has 

 so well described the making of simple and inexpensive 

 cages and aquaria in his book, "Insect Life," that, with 

 his permission, his account is quoted here. 



Live-cages. -"A good home-made cage can be built by 

 fitting a pane of glass into one side of an empty soap-box. A 

 board, three or four inches wide, should be fastened below
