 son. Teacher may accompany sections of ten or less pupils. 



Questions should be asked by the teacher while on these 

 trips with pupils. 



Lesson IV. The Robin's Nest 

 Find an old, last-year's robin's nest in good condition. This 

 can be studied by pupils and teacher together, noting its form, 

 size and structure. By carefully taking the nest to pieces, the 

 materials composing it can be determined and the relation of 

 these to each other. Careful note should be made of every kind 

 of substance found making up the nest. 



Lesson V. Construction of the Nest 

 Find if possible a nest in the process of construction. Pupils 

 and teacher together may visit this at intervals. With proper 

 precautions so as not to disturb the birds any more than neces- 

 sary, individual pupils may watch the nest at all times during 

 the day. By working in relays, the whole process of nest build- 

 ing may be witnessed by the class. The following points among 

 others should be given attention: 



a. Frequency with which material is brought to nest. 



b. Nature of material. 



c. Method of shaping nest.
