as far south as Fry’s Hill. The hills to the west of this range along the 
southern border of the alluvial plain have not been examined, but from 
the facts just mentioned it is probable that boulders of this kind lie con- 
cealed beneath the detritus throughout the whole extent of that part of 
the Wyomanock Valley lying between Snake Hill and New Lebanon. 
Boulders of gray quartzite have been mentioned as occurring along 
the western slope of the Canaan and Lebanon Range, and these seem to 
occur over all the region of the green quartzite boulders, besides being 
found also to the west of Snake Hill. It is probable that their origin 
might be found upon the hills lying still farther to the northwest. 
Quartzite boulders, both green and gray, may be found in all parts of 
the Shaker Valley, upon the Richmond Range, and in the Richmond 
Valley ; upon the Lenox Range also, and in the Lenox Valley they may 
be found here and there. Proceeding from Snake Hill to New Lebanon, 
and thence to Lenox Village and Lake Mahkeenac, the whole distance 
being seventeen miles, a continuous decrease in the number and size of 
the quartzite boulders may be noted, and algo a continuous increase in 
the marks of abrasion which they bear. 
CHLORITIC SCHIST BOULDERS. 
a. PRINCIPAL ۰ 
1. Distribution, — Upon Fry's Hill originates a train of boulders com- 
posed of the chloritic schist of which the hill itself is made up. From 
the summit of the hill the train descends in a S, 54° E. direction, then 
bends gradually to the southward, till at the base of the range, one 
fourth of a mile northwest of the North “ Family” of Canaan Shakers, 
it has a S. 27° E, direction. From this point the train extends just 
south of the North Family, and up the face and along the crest of a 
westerly spur of the Richmond Range, called Merriman's Mount, to the 
crest of the Western Branch of the range. In so doing, it gradually 
changes its direction to S. 68° E., with which direction it crosses the 
upper end of the Haskell Valley, and begins the descent of the eastern 
slope of the Richmond Range. In making this descent, it bends consid- 
erably to the south, crossing the main road in Richmond two miles north 
of the railroad station, till it attains a S. 25° E, direction, near Mr. Oscar 
Smith’s house, where it crosses the Boston and Albany Railroad. From 
the railroad the train continues on across the Richmond Valley with the 
same direction, passing near Mr. Werden’s house in the southeast part 
of the town, and curving to the eastward as it mounts the western slope 
of the Lenox Range, crosses its two parallel ridges, and descends into 
the Lenox and Stockbridge Valley, where its direction is S. 50° E.
