ing the dip of the limestone under the schist. The synclinal 
character of Lenox Mountain, and the tray-like character at the 
32. Ww, orGlendale "33, W. Stockbridge, Fuarey's Q. 
south, is sustained by the sections; and this indicates that the 
limestone of West Stockbridge and Stockbridge are the same 
continuous stratum; a fact further apparent from their actual 
continuity to the northward in the town of Pittsfield. 
Section 34. Through Monument Mountain from the east 
side of the Housatonic River, at Housatonic village, in a 
southwest direction, nearly to the road from Great Barrington 
to Stockbridge. It gives the true dip at the east and west ex- 
tremities of the section, and the mean dip of the intermediate 
portion; also the dip of the limestone at a quarry to the east 
of the eastern foot, near the Stockbridge road. It has two 
masses or strata of quartzyte with arenaceous or quartzytic

mica schist between, and a thin bed of the same schist under- 
neath the western quartzyte. No exposed section shows the 
rock underlying the western lower schist; but the dips of the 
schist to the westward of the river, with the underlying lime- 
stone, as explained above (p. 401), leave little doubt that the 
limestone passes beneath the mountain. The upper and: lower 
quartzyte may be the same stratum in an overthrust fold as 
represented in the following figure. In that case, the limestone 
off the east end of the mountain isa part of the underlying 
limestone at the upward bend. The position of the quartzyte 
and mica schist strata west of the mountain and of the Housa- 
tonic River harmonizes with this view, as shown in the explana- 
tions already given (p. 401). A line drawn from the elevation
