should be done chiefly with the idea of learning about the 

 animals rather than with the notion of getting as many 

 specimens as possible. To collect, it is necessary to find 

 the animals alive; one learns thus their haunts, their local 

 distribution, and something of their habits, while by con- 

 tinued work one comes to know how many and what 

 different kinds or species of each group being collected 

 occur in the region collected over. Collecting requires 

 the sacrifice of life, however, and this will always be kept 

 well in mind by the humane teacher and pupil. Where 

 one set of specimens will do, no more should be collected. 

 The author believes that high-school work in this line 

 should be almost exclusively limited to the building up 

 of a common school collection. Let a single set of speci- 

 mens be brought together by the combined efforts of all 

 the members of the class, and let it be well housed and 

 cared for permanently. Each succeeding class will add 

 to it; it may come in time to be a really representative 

 exhibition of the local fauna. 



The high-school collection should include not only 

 adult specimens of the various kinds of animals, forming 

 a systematic collection, as it is called, but also all kinds 

 of specimens which illustrate the structure and habits of 

 the animals in question and which will constitute a 

 so-called biological collection. Specimens of the eggs 

 and all immature stages; dissections preserved in alcohol 

 or formalin showing the external and internal anatomy; 

 nests, cocoons, and all specimens showing the work and 

 industries of the various animals ; in short, any specimen 

 of the animal itself in embryonic or postembryonic con- 

 dition, or any parts of the animal, or anything illustrating 

 what the animal does or how it lives, all these should be 

 collected as assiduously as the adult individuals. Each 

 specimen in the collection should be labelled with the 

 name of the animal, the date, and locality, and the name
