Biological Station 



COURSES FOR UNDERGRADUATES AND 

 GRADUATES 



It is not the purpose of the Station to duplicate the work offered 

 at the University, but to provide facilities for field work of a sort 

 that cannot be so well carried on under urban conditions or with 

 the restrictions imposed by a university schedule. Instruction is 

 limited to the courses announced, but qualified students may arrange 

 to follow other lines by electing the special courses. A student may 

 give his entire time to either botany or zoology or may divide it 

 between these subjects, but no student is permitted to take work for 

 more than eight hours University credit. Each of the four-hour 

 courses is planned to occupy one-half the student's time, the two- 

 hour courses, one-quarter ; the special courses may take the whole 

 or any part of the time. In all courses, except Plant Anatomy, at 

 least half the time is spent in the field. The work of research stu- 

 dents will be arranged in accordance with the nature of the prob- 

 lem selected. 



Each course occupies the entire working day assigned to it, and 

 consists of field or laboratory work, supplemented in every case by 

 lectures, recitations, or conferences, and by assigned reading and 

 preparation of reports. Each course normally requires time for 

 reading and study in addition to the hours scheduled for field and 

 laboratory work. It will not be possible for students carrying full 

 work (eight hours) to spend their week ends away from the Station. 



Zoology 



101. The Natural History of Vertebrate Animals. — The course 

 deals chiefly with fishes, amphibians, and reptiles, not with birds 

 (see Course 107), and only incidentally with mammals. As far as 

 possible representatives of all forms of fishes, amphibians and rep- 

 tiles occurring in the region are collected, identified and studied in 

 both field and laboratory. Particular attention is given to the ecology 

 of the several species and correlated studies of the food, habitats, 

 enemies and interrelations of the various species are made. The 

 general problems of evolution, distribution and taxonomy are con- 

 siderd as opportunity offers. Although most of the work is given in 

 the field, attention to precise methods of observation and to the cor- 

 rect use of data is required. 



Thursday. Two hours credit. Professor Smith. 



Prerequisites : Elementary collegiate zoology. 



This course gives one hour credit to graduate students. Such 

 students, wishing full credit, must perform extra work, and will reg- 

 ister for Course ioi#. 



103. The Natural History of Invertebrate Animals with Refer- 

 ence to the Principles of Ecology. — This course deals mainly with the 

 more important features of animal ecology as exemplified in the 

 aquatic invertebrates of the Douglas Lake region. A detailed study 

 of the typical aquatic habitats is made in connection with the field
