of it is fairly pure, and in such places it carries a considerable amount 
of finely foliated talc. Near the center of the steatite is what appears 
to be a horse of chlorite schist, completely surrounded by steatite, 
antl carrying chlorite in large deep-green plates. A similar mass of 
chlorite carrying octahedra of magnetite exists in the Rochester area. 
On the west side near the center, the serpentine is in contact with a 
narrow band of chlorite schist; this is followed beyond by a highly 
folded dark schist with layers of granular quartz. The same rocks are 
found forming the contact on the southwest. Both schists are nearly 
vertical, and where strikes could be obtained, the schistosity shows 
evidence of curving around the area of serpentine and steatite. On the 
east side the schist is only exposed in one place, and here it is badly 
weathered. 
14. Loicell. Twenty-five miles north -northeast of Waterbury at 
"Chrysotile," on the side of Belvidere Mountain. Carries asbestos. 
Described by Marsters (3) and Richardson (2). 
15. Loivdl. Five and a half miles northeast, near village of Lowell. 
Large, but length doubtful, width one mile. 
16. Lowell. A short distance east of the last area. Size doubtful. 
Lnsuccessful attempts were made to find areas reported in the 
"Geology of Vermont" in the towns of Newfane, Warren, Waitsfield, 
Middlesex, Waterville, and Westfield. In the last named town at 
Hazen's Notch (Loc. 17 on map), serpentine was found, but it was 
doubtful whether it was in place. In the others no serpentine was 
found where indicated on the map, but the rock may nevertheless exist 
in these places, as in no case was more than one day spent hunting for 
a locality if it could not then be found. No attempt was made to visit 
the areas reported in Enosburg, Montgomery, and Richford. 
Petrography. 
A study was made of sixty -four thin sections of serpentine from the 
different localities. The specimens were selected to show as much 
variety as possible; from the contacts, the center, the north and south 
ends, etc. When examined, however, they showed a remarkable 
uniformity. Alteration from the parent rock has always been com- 
plete; only in a few cases were any original minerals present. Nor- 
mally about three quarters of the section is serpentine either platy or
