VI 11 SUGGESTIONS TO TEACHERS. 



fresh zest to t/he work. If any opportunity offers, the class should 

 visit a menagerie, book in hand, name the animals, and verify the 

 statements of the text. 



The knowledge of the teacher should be sufficient to fill out and 

 supplement the brief descriptions of a text-book. The following 

 works will furnish additional facts, and aid in further investigations. 

 Pupils may often be persuaded to procure copies as a foundation 

 for their library: Packard's "Guide to the Study of Insects," and 

 his "Zoology"; Dana's "Corals and Coral Islands"; "The Standard 

 Natural History"; Coues' "Key to North American Birds"; Baird, 

 Brewer, and Ridgway's "North American Birds"; Emerton's "Life 

 on the Sea-shore"; Carpenter's "Comparative Physiology"; Jordan's 

 "Vertebrates of North America"; Glaus and Sedgwick's "Zoology." 

 The back volumes of the "American Naturalist," "Science," "Popu- 

 lar Science Monthly," and "Harper's Magazine" (see Natural History 

 in the Index volume), contain numerous excellent articles, many of 

 them finely illustrated. The above-named books, as well as a micro- 

 scope, so essential to efficient instruction, can be obtained of the 

 publishers of this work, Messrs. A. S. Barnes & Co., Ill and 113 

 William St., New York. Specimens of all the typical species of ani- 

 mals, as well as many beautiful casts, are constantly kept for sale 

 by Prof. Henry A. "Ward, Rochester, N. Y. Skins for study of either 

 birds or mammals, or handsomely mounted cabinet specimens, also 

 material for laboratory work as well as dissecting instruments, can 

 be obtained of J. M. Southwick, Providence, R. I.
