Tuesday and Thursday. Four hours credit. Mr. 

 McFarland. 



A'o prerequisite. 



This course does not give credit to graduate students. 

 It is accepted at the University in lieu of Botany I and 2 

 as a prerequisite to advanced courses in botany. This 

 course and Zoology 7, taken together, offer eight hours 

 work in biology, open to all students without prerequisite, 

 and substantially equivalent to General Biology at the 

 University. 



2. Systematic Botany. — The chief aim of this course 

 is to acquaint the student with the flora about the Station 

 and to give him facility in the identification of plants 

 by the Manual. About one hundred species of plants are 

 identified in the field, the characteristics of the more im- 

 portant families of flowering plants are learned, and the 

 general principles of the classification of plants are pre- 

 sented. There is excellent opportunity for the collection 

 and preparation of material for the herbarium. Students 

 who complete this course successfully should be able to 

 identify readily the native flora in any section of the 

 country. 



Wednesday. Two hours credit. Dr. Gates. 

 Prerequisite : Elementary collegiate botany. 

 This course gives one hour credit to graduate stu- 

 dents. 



3. Ecology. — This course serves as a general intro- 

 duction to ecological field work and the methods of eco- 

 logical research, with particular reference to the study 

 of plant associations. Practice is given in the recogni- 

 tion of associations, the determination and description of 

 their structure and successional relations, and the meas- 

 urement of some environmental factors. Particular at- 

 tention is given to the dynamic factors of the environ- 

 ment, to their effect on the present structure and future 

 development of the plant community, and to the role of 

 the individual plant in promoting or retarding these ef- 

 fects. Because of the large number of associations in 

 the region, it is impossible to study more than the most
