OUTLINE OF ANIMAL STUDY. 33 



Starfish. — General structure. Read or talk about home, life, and habits. 

 Adaptation of structure to life. The stai-fish as a type of the radiates. 

 Compare -with sea-urchin (November). 



ARTICULATES. 



Woi'ms. — Earthworms, homes, habits (movements, food, bun-owing), 

 value to man, general structure, including segments, legs, blood vessels 

 and alimentary canal (visible through skin). (October.) 



Insects. — Any insect not previously studied. Aquatic insects good. 

 Emphasize life history, structure, and classification (September). 



Crustacea. — ^Crayfish, habits, general structure, life history, compari- 

 son with sowbug, lobster and crabs (September and October). Classifica- 

 tion of arthropoda (October). 



VERTEBRATES. 



Birds. — With more attention to classification (May). 



Mammals. — One or two compared with any other class of A^ertebrates. 

 Classification of vertebrates (November). 



General Classification. — Classifying all animals studied during the 

 four years (December and June). 



CClose of First Cycle of Animal Study.') 



FIFTH YEAR. 



CBeginning of Second Cycle.} 



Special Work. — Articulates or jointed animals, including the arthro- 

 poda or jointed limbed animals and the vermes or worms. 



ARTHROPODA 



(September to December). 

 Includes insects, spiders, Crustacea, and myriopoda. 



ORDER OF STUDY. 



Life History.— A careful study of the life history of two not studied 

 before. The development of the mosquito or fly can be readily watched 

 (September). 



Relation to Environment. — Occurrence, homes, food, habits, studied 

 in field lessons as much as possible. Children encouraged in out-of-door 

 observations. Living animals kept in school- room (September and October). 



Relation to Man. — Injurious and beneficial insects ; value of the spider ; 

 use of crayfish, crab, and lobster for food. 



Structure and Comparison. — Study carefully, draw, and describe care- 

 fully and fully at least one animal belonging to each of the four divisions 

 of arthropoda, and compai-e with the others. 



Classification and Related Forms. — Study distinctive characteristics of 

 insects and of their most common orders, and' of other classes of arthro- 

 poda. Put all emphasis on distinctive characteristics. During November
