BARTON: TEACHERS’ SCHOOL OF SCIENCE. 
437 
The field course in geology, under the charge of the Curator of 
the School, has now a fairly definite two years’ course. The ten 
lessons in the spring finished that series and were especially devoted 
to the subject of historical geology. This involved visits to many 
places at a distance from Boston, as Attleboro, Haverhill, Mt. 
Wachusett, Mt. Holyoke and the Connecticut valley, and Gay Head. 
Owing to bad weather many of these lessons were given under 
much difficulty. The largest number present at a single lesson was 
39, the smallest was 10. The average attendance Avas 24.3. 
A new two years’ course began in the autumn AAUth an aimrage 
attendance of 46.3. The largest number present at one time was 
70, the smallest 29. With one exception all the places visited are 
in the immediate vicinity of Boston. The one lesson at a distance 
Avas in the vicinity of North Adams, Avhere a brief study was made 
of the structure of the Hoosac and Graylock mountains, and obser¬ 
vations were made of the Massachusetts plateau and its deeply 
incised valleys. A lecture illustrated by lantern slides Avas given on 
Saturday evening in the State Normal School building, through the 
courtesy of the principal, Mr. F. F. Murdock. 
The spring course has begun Avdth an attendance of 50 and will be 
reported upon next year. 
These lessons in geology are designed to train the members of 
the class in the methods of observation, how to correlate the results 
of their observations and finally Avhat conclusions shall be drawn 
from their results. In addition, a general knoAvledge of the various 
species of rocks, their structures and stratigraphical relations is 
given. 
Laboratory Courses. 
Each of the laboratory courses consists of a series of fifteen les¬ 
sons of two hours each during a term of four years. Short exami¬ 
nations are given at each exercise and at the end of each year a 
final examination of three hours is given. 
Those members who have passed satisfactory examinations during 
the four years, receive a diploma stating the kind and amount of 
work accomplished.
