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, 

 I am indebted to the gentlemen whose names are annexed. 



4. By Mr. J. Stuart, of Peacham, Vermont. 



1. 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 broken, 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- 

 tions, are almost Alpine mountains. Approaching the quar- 

 ry from the south, it is level for some distance, until we ar- 

 rive upon 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 the 

 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. Finely crystallized as usual in six-sided 

 prisms. Lyndon, Vermont. 



3. Cyanite, in small quantities, small garnets, and tourma- 

 line, are found in Peacham and its vicinity.
