Miscellanies. 399 
in the Connecticut valley, I was reminded of having read something 
of an analogous kind many years ago concerning a locality in Ten- 
nessee, which I would beg leave to lay before you under the hope 
that some of your intelligent readers in that neighborhood may ex- 
amine into this subject more particularly. 
‘‘ Extract from the American Encyclopedia, published by Dobson 
at Philadelphia, 1778 to 1803—Supplement, vol. 3, p.344. From 
a meagre account of Tennessee, I extract the following: ‘The 
enchanted mountain, about two miles south of Brass town, is famed 
for the curiosities on its rocks. ‘There are on several rocks a num- 
ber of impressions resembling the tracks of turkeys, bears, horses, 
and human beings, as visible and perfect as if they were made on 
snow or sand,’ &c. There are other particulars stated which seem 
to be loose guesses of ignorant people, &c.” 
We are not aware whether Dr. Troost, the learned and able 
geologist of ‘Tennessee, has investigated these facts, or whether they 
have fallen under his observation. If the alledged facts are real, we 
should be glad to know his opinion of them, and we should be 
greatly obliged, if in compliance with our English correspondent 
and with our own, any facts may be communicated relating to im- 
pressions on rocks.—Eb.

4. New locality of Iolite, with other minerals assoctated.—About 
two years ago, I discovered a locality of zolite in this place. I have 
subsequently revisited it, and take this opportunity of communica- 
ting to you the result of my observations. 
The zolzte is found about one mile and a half N. E. of the vil- 
lage of Brimfield, on the road leading to Warren, and near the resi- 
dence of Samuel Patrick. It is of a violet blue color, sometimes 
with a shade of brown: fracture uneven: translucent: structure 
foliated. I have obtained no specimens which show the crystalline 
form. Externally, it differs very little from that found at Haddam, 
Conn., except that the hues are more vivid, and the tabular masses 
are not as large. I am not aware that other localities have been 
discovered in this country. ‘The accompanying rock is well char- 
acterized granite. 
In connexion with the zolzte, occurs adularia of a wine yellow and 
sometimes greenish tint. Some of the specimens possess the cha- 
toyant appearance. They display a strong pearly lustre, and are
