Announcement of the 



although this number may be exceeded if absolutely necessary. Inas- 

 much as students will be received into these courses in the order of 

 application, it is advisable to notify the Director or the several in- 

 structors as early as possible. 



The courses are given chiefly in the field and for this reason 

 it is impracticable to make changes in the schedule as announced. 

 Students enrolled in the research courses do their work on the most 

 convenient days. 



Registration blanks will be filled by each student after arrival 

 at the Station. Students from other institutions may arrange for a 

 transfer of credits through the Director and the Registrar of the 

 University. 



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. 



Graduate students, when regularly matriculated in the Univer- 

 sity and properly registered with the Dean of the Graduate School, 

 may carry on work at the Station which will count toward an ad- 

 vanced degree. 



For full information concerning the requirements for advanced 

 degrees, address the Dean of the Graduate School, Ann Arbor, Mich- 

 igan.
