formal instruction but is intended for those who wish to 
take up special work or to do research under direction. 
Studies may be made in animal behavior, in the meaning 
of color in its relation to environment, in mimicry and the 
like. A number of problems in these fields have been 
already outlined and are awaiting solution. Two, four,

BOTANY. 
1. Field and Forest Botany.—This course will be 
made of especial interest to those students who desire an 
acquaintance with the life and habits of plants in their 
natural surroundings, and with the correlation between 
the environment and the structure of the plant. The 
work will consist of field trips, laboratory exercises, and 
lectures. In the field the student will become familiar 
with the commoner trees, herbaceous plants and ferns 
of the vicinity, and with the plant associations in which 
they grow. ‘The various factors influencing the distri- 
bution of plants and their grouping into definite associa- 
tions will be considered as fully as the time will allow. 
The effect on the vegetation of certain external factors, 
such as the water content of the soil, the topography, and 
the light, will be studied. The topography of the region 
is so varied that a wide range in ecological factors is 
produced, and consequently a large number of habitats 
with varied flora is available for study. In the labora- 
tory, a study will be made of the structure of some plants
