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 

 XII. 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 the technical notes in the chapter 

 (XXI) devoted to insects are numerous suggestions re- 

 garding the obtaining and care of certain kinds of insects 

 which may be reared and studied to advantage in the 

 schoolroom. In the following paragraphs are given direc- 

 tions for making the necessary live-cages and aquaria for 

 these insects.

 so well described the making of simple and inexpensive
