the insectivorous plants, the orchids, and some of the 
herbaceous plants of the region, and with the plant asso- 
ciations in which they grow. ‘The effect on the vegeta- 
tion of certain external factors, such.as soil, water, and 
light, the adaptation of plants to winter conditions, the 
cross pollination of flowers by insects, the dissemination 
of seeds, and other similar subjects are demonstrated. 
In the laboratory a study is made of the structure of 
some plants, with chief attention to the relation between 
the form of the plant and the environment in which it 
lives. Four half days work in the field or laboratory and 
one conference weekly. Four hours credit. Dr. Wurt- 
FORD. 
2. Systematic Botany.—The chief aim of this course 
is to acquaint the student with the flora about the camp. 
The general principles of the classification of the higher 
plants are considered with special reference to the local 
flora. The flora is very rich in species and family types. 
There is an excellent opportunity for the collection and 
preparation of material for the herbarium. It is desired 
that students electing this course should have some pre- 
vious experience, however slight, in the identification of 
plants. ‘wo half days field work and one conference 
weekly. Two hours credit. Assistant Professor GLEA-

3. LEcoiogy.—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 
effects. Because of the large number of associations in
