790 feet. The same fine-grained granite is continued, oc- 
casionally traversed by veins lined with crystals of quartz; but 
containing no other minerals. 
774 feet. A narrow vein of sulphuret of lead, with walls 
lined with crystals of quartz. The fairest cubic crystals are 
slightly attached to the points of the quartz crystals. Yellow- 
ish crystals of carbonate of lime are often interspersed among 
the lead. Sulphate of barytes occurs here also; sometimes in 
plates meeting at various angles, and forming chambers lined. 
with minute crystals of quartz. Minute crystals of copper py- 
rites, and a little fluate of lime, have been found here; also 
fine specimens of bitter spar. The walls are very compact 
fine-grained granite. 
760 feet. Coarse, parti-coloured granite. The felspar is 
flesh-coloured and white; the quartz often bluish or greenish ; 
the mica silvery, greenish, or purplish. 
625 feet. A stratum of gray-wacke slate. Texture less 
firm than that of the same rock at the west of Pittsfield. This 
stratum is very distinct, and about two feet thick. s 
723 feet. A stratum of serpentine rock, containing very 
red quartz imbedded in various directions. It is very compact, 
and mostly green. Here it is but about three feet thick. 
About ten miles south of this place, on Maclure’s Springfield 
section, near the line between Westfield and Russell, and 
four miles west from Westfield Academy, I found this same 
stratum of very great breadth. I say the same stratum, 
because it is situated in the granitic hill, east of the highest 
ridge of granite, which is evidently a continuation of this 
range. Perhaps I may, hereafter, give you an account of 
"NY excursion along that section of Maclure, in which I may 
give you a more particular description of the Westfield ser- 
pentine,
