traveled in two reserved cars. Each member of the class was pro¬ 
vided with a printed. description of the various geological and geo¬ 
graphical features that can be seen on the way. At North Adams 
barges were in waiting which at once took the party over the'Hoosac 
Mountain range, giving them a chance to study its structure, and to 
visit the eastern portal of the Hoosac Tunnel. During the evening 
Mr. Murdock, principal of the State Normal School, kindly gave the 
class an exhibition of that building and the use of its large lecture 
room and stereopticon. By this means Professor Barton gave the 
class an illustrated lecture upon what had been seen during the day 
and upon the general geological formation and history of North¬ 
western Massachusetts. The next day was spent in a visit to the 
top of Mt. Greylock, in a study of its structure and its relations to 
the surrounding region. 
The field course has begun this spring with an attendance of

Bayville Summer Courses. 
A series of courses in natural history was given at Bayville, Line- 
kin Bay, Maine, beginning Friday, July 6, 1900, and continuing for 
three weeks. The following is an outline of the subjects that were 
studied : — 
Geology was given by Mr. A. W. Grabau. The elements of phy¬ 
sical geography, geology, and mineralogy were taught, chiefly by 
field excursions. A study of two small rocky islands was under- 
taken, and topographic and geological maps were prepared by the 
students. A relief model of the smaller of the two islands was made 
by the students. 
Zoology was conducted by Mr. Freeland Howe, Jr. In this 
course the habits and structure of representative types of animals 
were studied, especially the littoral forms, and besides the laboratory 
work, observation lessons in the field were also given by the 
instructor. 
Botany was conducted by Mr. C. E. Preston. Common plants 
were studied and special attention was given to the methods of plant 
analysis and dissection. Considerable attention was given to the 
common trees of the region, and the relation of plants to their en¬ 
vironment was considered.
