mals in the laboratory; here the adaptations which make 
certain organisms suited to particular habitats are stud- 
ied. ‘The records made in the field form the basis for 
written reports, and reading is required. In the confer- 
ences, the relation of observations to general problems is 
‘discussed. 
This course attempts to give an intimate knowledge 
of outdoor life, to make one at home with invertebrates 
in the field. 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 are studied 
with especial reference to their environment. ‘The field 
work includes identification, observations on habitat pref- 
erences, food habits, nestling activities, and the early 
autumnal migration movements. In the conferences at- 
tention is given to the economic relations of birds to 
man, their seasonal distribution, and the facts and theo- 
ries of their annual migration movements. The bird fauna 
is abundant and includes many representatives of north- 
ern species. Two half days of field work and one con- 
ference weekly. Two hours credit. Dr. E1iis and Mr. 
COMPTON. 
4. The Natural History of Insects—This course is 
intended to give the student a general acquaintance with 
the insects of the region and to afford opportunity for 
the study of the various forms in their native habitats. 
Field studies are made of the life histories, habits, and 
activities of insects belonging to various orders. Em- 
phasis is placed upon the relation of insects to their en- 
vironment, and their economic relations are also consid- 
ered. Some work on the morphology and physiology of 
insects is included. Opportunities are especially good 
for the study of aquatic forms, and considerable time 1s 
devoted to them. In connection with the field work at- 
tention is given to the methods of making accurate ob- 
servations and the proper recording of the same. In-
