TO THE EDITOR. 
Sir,—On looking over Dr. Robinson’s catalogue of locali- 
ties of minerals, | find there are several, which come within 
my knowledge, that he has not named. I! take the liberty 
to send you a list of some of them. I donot know that you 
will think them worth noticing; you will, however, dispose 
of them as you please. 2 oe 
1. Sulphate of Alumine. 'Thereisa locality of this in Bol- 
ton, Conn. ‘This is found in decomposed mica slate, in the 
eastern part of that town. The specimen I have is of a 
very decided charaeter, and there is an abundance of a 
similar kind to be found in the same place. 
2. Quartz. Crystals, both plain and coloured, perfectly 
transparent, are found in Stafford. Conn., about two miles 
west of the Springs, of about half an inch in diameter. 
One I have in possession is of a beautiful yellow, the others 
plain. 
3. Garnets. These are dispersed in great abundance 
through the gneiss and mica slate rocks, in Monson and Staf- 
ford, and in other parts of the same range of mountains. 
Some crystals are found that are quite transparent. In 
Stafford, around the margin of what is called Square Pond, 
among the gravel, garnets may be collected in great numbers. 
4, Steatite. There isa mountain in Somers, Conn. where 
a considerable quantity of this stone has been found. It 
exists in beds in different parts of the mountain, in gneiss 
rock, and is accompanied with several minerals that are 
found in veins,and in fissures. Within two years past, consider- 
able quantities of this stone have been quarried. Blocks are 
transported about a mile and a half, to a mill built for the pur- 
pose, in the form of a common saw-mill; it is there sawed into 
slabs, and thence carried to Springfield, Hartford, and else- 
where, to be wrought. It receives a fine polish, and is an 
excellent stone for fire-places, as well as other purposes for 
which soap-stone is used. 
5. Sulphur. Small quantities of this are found, very pure, 
in the crevices of the soap-stone rock, in Somers, Conn.
