86 NATURE STUDY. 



4. Rabbit and cat. 



5. Rabbit, chicken, and fish. 



6. Rabbit and caterpillar. 



Written summaries are usually more definite and 

 exact. Have these read and discussed in class. 



Pupils can apply what they have learned about classi- 

 fication by writing the following lists of animals : 



1. A list of all the animals they can think of which 

 are vertebrates. 



2. A list of all the animals they can think of which 

 are not vertebrates or are invertebrates. 



3. A list of vertebrates which are also mammals. 



4. A list of mammals which are also carnivorous 

 animals. 



5. A list of mammals which are also gnawers or 

 rodents. 



Why is our rabbit classed with the vertebrates? 

 With the class mammals ? With the order rodents ? 

 With the family of hares ? 



ADAPTING WORK TO OTHER, GRADES. 



For Grades or Years One and Two. 



The work as planned will certainly occupy two weeks, 

 forty-five minutes to an hour a day. Little folks could 

 not do much of the work outlined ; it would be difficult" 

 to keep them thoroughly interested in one topic so long. 

 They are most dependent on their senses, must have 

 work most closely related to their child-life, and have 

 very little power of reasoning or of abstracting.
