28 BULLETIN OF THE 
Beyond a point situated in the northeastern part of the town of Stock- 
bridge, half & mile southeast of Mr. Luther Butler’s house, near the 
Stockbridge and Lenox line, the train seems to lose its continuous char- 
acter, the chloritic schist boulders in the same line to the southeast 
being few, small, and widely separated. 
The different groups of chloritic schist boulders are represented on 
the map by red dots. They are not intended to show the exact number 
of boulders, or their size relatively to the other dimensions represented 
on the map. The position and width of the different groups, and the 
comparative abundance and size of the boulders in different localities, 
are, however, indicated with an approach to accuracy. 
The profile of the section given below the map shows the irregulari- 
ties of surface over which the principal train passes, as the section was 
taken very nearly along the course of that train, and is represented 
without exaggeration of the vertical scale. 
The greatest depth of valley at the crossing of this train is, in the case 
of the Shaker Valley, 650, and in that of the Richmond Valley, 550 feet. 
2. Width. — The train just described is perfectly distinct throughout 
its entire length, a distance of about nine miles. The following table 
shows its approximate width at various points.

3. Comparative Abundance of Boulders. — From the summit of Fry’s 
Hill to a point one fourth of a mile tó the southeast of it, the chloritic 
schist boulders are so abundant as to almost entirely cover the founda- 
tion upon which they rest, while on passing along the train to the south- 
east, a well-marked, though not perfectly continuous, diminution in their 
number may be observed. The following table gives the localities where 
the boulders of this train occur in special abundance. 
Table of Localities specially abounding in Boulders. 
(1.) Eastern slope of Canaan and Lebanon Range. 
(2.) Both sides of main road, Richmond, 2 m. north of R. R. station. 
(3.) Bed of brook, 2 m. S. W. of North Family of Shakers.
