J4 Announcement of the 



ods of collecting and preserving insects in all stages of development. 

 Opportunity is afforded to form individual collections of properly 

 determined specimens. 



Monday. Two hours credit. Assistant Professor Ellis. 



Prerequisite : Elementary collegiate zoology. 



This course gives one hour credit to graduates. Students de- 

 siring full credit, must complete extra work, and will register for 

 Course io$a. 



107. Ornithology. — In this course, birds are studied mostly dur- 

 ing their breeding season, but in the latter part of the session, there 

 are opportunities for studying early autumnal migration movements. 

 Special attention is given to identification of birds and methods of 

 field study. Bird behavior and especially nesting habits are consid- 

 ered. Lantern' slides are used in studying identification characteris- 

 tics and for illustrating bird behavior. The bird fauna is ample for 

 the course, and it is interesting especially because of the northern 

 species breeding here under wild conditions. There are conferences 

 when various ornithological topics are discussed. 



Saturday morning, and two or three early morning trips to be 

 arranged. Two hours credit. Mr. Hussey. 



Prerequisite : An elementary collegiate course in zoology, botany 

 or biology. 



Course 107 does not give credit to graduates. 



109. Special and Research Work in Zoology. — Students who do 

 not find under the formally announced courses in zoology, work suited 

 to their needs or attainments, may, if properly prepared, elect Course 

 109. Those qualified to work independently will find numerous prob- 

 lems to engage their attention. Every encouragement in the direc- 

 tion of profitable research and the publication of results will be 

 given. Advanced students as well as independent investigators who 

 can foresee special needs are advised to notify the Director who will 

 endeavor to provide the necessary facilities.

 tion are recommended to choose subjects in the following fields :
