mals in the laboratory; here the structural adaptations 
which make certain organisms suited to particular habi- 
tats will be studied. The records made in the field will 
form the basis for written reports, and reading will be 
required. In the conferences, the relation of observa- 
tions to general problems will be discussed. 
This course will attempt to give an intimate knowledge 
of out door life, to make one at home with invertebrates 
in the field. Exact methods will be used in making ob- 
servations, and an effort will be made to correlate the 
facts observed with the general principles of biology. 
Four half days of field or laboratory work, and one or 
two hours devoted to conference or lecture weekly. 
Four hours credit. ASSISTANT PROFESSOR SMITH. 
3. Ihe Natural History of Birds.—Birds will be 
studied with especial reference to their environment. 
Field work will include identification, observations on 
habitat preferences, food habits, nesting activities and 
the early autumnal migration movements. In the confer- 
ences attention will be given to the economic relations of 
birds to man, their seasonal distribution and the facts 
and theories of their annual migration movements. The 
bird fauna is abundant and includes many representatives 
of northern species. Two half days of field work and 
one conference weekly. Two hours credit. ASSISTANT 
PROFESSOR SMITH. 
4. The Natural History of Molluscs——The molluscs 
of the region will be collected and identified and field 
studies made of their relations to environment and their 
meaning in the biology of the region. An opportunity 
will be afforded to become familiar with the literature 
of systematic conchology and to form individual collec- 
tions of properly determined specimens. Such collec- 
tions should be of great value to teachers. Two half days 
of field work and one conference weekly. Two hours 
_credit. Mr. BAKER. 
5. Individual Course. Special and Research Work in 
Evolution and Behavior.—This course does not involve
