like the Quincy granite of Massachusetts. It would make an excellent stone for orna- 
mental pillars, especially for inside work. Most of the blocks quarried are used at Cole- 
brook for buildings, not for cemeteries, the stone from Brunswick, Vt., along the Grand 
Trunk Railway, supplying that want. A few years since Mr. Parsons employed from 6 
to 8 hands constantly; now only half that number is needed. Blocks of any size that 
can be conveniently handled can be quarried here. There have been as yet no orders 
for this stone from any distant locality requiring railroad transportation. The Bruns- 
wick granite is related to that from Concord, and, being favorably situated as regards 
transportation, is used extensively in northern New England. 
St. Fohnsbury Granite Company. This concern uses granite from several localities, 
making a specialty of monumental work. They use most extensively a biotite granite 
from Blue mountain, Ryegate (one that cuts the Calciferous mica schist) ; and, on ac- 
count of the strong contrast between the white feldspar and the black mica, it has a very 
clean aspect. By leaving the letters and ornamental work raised and polished, an inter- 
esting effect is produced, as it makes a strong contrast with the main body of the stone. 
It receives and retains a high polish. Their gray granite comes from Brunswick, Vt. 
They are also beginning to use a red biotite granite from Stark, the same with one that 
has been described in the other parts of this report. It resembles somewhat the red 
Scotch granite, but is superior to the imported article, because it is finer, and is not 
permeated with the ‘‘pin-holes” constantly occurring in the other. This company is 
doing a large business. They have a mill for polishing granite close by the St. Johns- 
bury depot, using steam, and employ a large number of workmen. The use of the 
“Conway granite” from Stark is the only known instance of the extensive employment 
of this variety of stone from a New Hampshire locality. There is a good mass of it at 
Biddeford, Me., that is extensively used. 
I have the following additional statements respecting the St. Johnsbury Granite Co., 
from R. W. Laird, treasurer. The Blue mountain granite requires 24 miles of trans- 
portation to the railroad. It is entirely free from iron, and blocks may be quarried 
300 to 4oo feet long and ten feet square. Monuments made of the three granites 
were exhibited at the Centennial exhibition at Philadelphia, and the red Stark stone 
received a medal and diploma, with the following award: ‘‘ For the good quality of the 
material, the originality of design, and the workmanship of the articles exhibited.” 
80 workmen are employed in April, to be increased in the summer to Ioo. Monu- 
ments are sent to every part of the country, especially the Middle states. The red 
granite is wrought from boulders. 
Lebanon Granite. This may be taken to represent a type of granite very unlike any 
others that have been mentioned, and it is worked at Walling’s quarry in Lebanon; at 
Freeman’s, one less extensively opened, further north in the same town; on Corey hill, 
and other places in Hanover and Enfield. It is properly a protogene gneiss. Itis a 
heavy, massive stone, better capable of sustaining weight than the Concord variety. 
S. H. Walling & Son do a large business, and supply the wants of Lebanon, mainly, for 
building purposes. Stone of very large size can be obtained here. The rock is free
