simple breeding-cages (for directions for making see p. 

 332) in the schoolroom. Such are the black and yellow 

 swallow-tail butterflies (fig. 127), the black and red-brown 

 monarch or milkweed butterfly, the somber mourning- 

 cloak, and the abundant cabbage-whites and sulphurs of the 

 fields. The same is true, too, of some of the largest and 

 most beautiful moths. The great 

 silken cocoons of the cecropia and 

 polyphemous moths can be found in 

 winter, when the branches are bare, 

 in orchard trees. They can be kept 

 in the schoolroom, where the issuance 

 of the great moth can be carefully 

 watched; how the wings gradually 

 unfold and expand and dry, and the 

 colors grow brighter and sharper, until 

 the splendid creature is ready to take 

 wing in search of food or mates. 



In the recent wide interest which 

 the popular study of animals has at- 

 tained, birds and moths and butterflies 

 have been given special attention by 

 the writers of books, and by means of 

 pictures made from photographs of the 

 live animals many finely illustrated 

 accounts of the hfe of various birds and insects have been 

 published. Scudder's " Every-day Butterflies," Mary 

 Dickerson's "Moths and Butterflies," and Ehot and 

 Soule's "Caterpillars and their Moths" are admirable 

 examples of such books. Reference to them will give 

 suggestions for an unlimited amount of observation. 

 Scudder's " Life of a Butterfly " is a detailed account of 

 the monarch butterfly. Holland's " Butterfly Book " is 

 a finely illustrated manual of our butterflies by the use of 

 which any butterfly specimen can be named.
