REMARK by Dr, Porter. 
Some of these localities are already known to the public, 
-and are here cited again for the sake of conveying some ad- 
ditional information. For my knowledge of several of them, 
Tam indebted to the gentlemen whose names are annexed. 
4, By. Mr. J. Sruarrt, of Peacham, Vermont. 
i. Asbestos and Serpentine. One piece of the latter was 
from the mountain in Kellyvale, and the other from the 
streets of Peacham, where it is stated to be very abundant. 
Of the asbestos, one Kind occurs in rolled pieces, which, 
when eke are found to contain a substance in color and 
texture resembling the finest cotton. ‘The other is discov- 
ered in crevices of the rocks of serpentine, and more resem- 
bles flax. The place from which they were obtained is in 
Kellyvale, about twenty miles from Canada. The adjoin- 
ing country, like most of Vermont, is primitive. The 
stones are principally granite. Farther back in all direc- 
vee are almost Alpine mountains. Approaching the quar- 
r m the south, it is level for some distance, until we ar- 
ee nal the top of a steep precipice, about two hundred 
feet high, at the foot of which there is a very small stream. 
All along the declivity are masses of serpentine, much of 
which is rolled to the bottom; and from appearances rs a 
same mineral extends to a great distance into the side of | 
the precipice. The quantity of asbestos as well as serpen- 
tine, seems inexhaustible. But though the serpentine would 
make excellent chimney-pieces, &c. yet it will probably 
never be wrought, on account of the difficulty of transpor- 
tation. 
2. Quartz. ey Sg ge as usual in six- “sided 
prisms. Lyndon, Vermon

line, are found in beg ress and its vicinity
