in part of organic remains. Next in succession are found strata of gray 
marble, two and a half feet thick; it receives a fine polish, but the 
colotir is not admired. A stratum of darker colour follows this which 
is six inches thick, though valuable only for stepstones. Then follows 
the black marble, which for brilliancy of polish and beauty of colour, 
perhaps, has no rival. The whole stratum is ten and a half feet thick. 
Veins of organic remains run at irregular distances from each other 
through the strata; these veins are from two to four inches thick, run- 
ning ten and sometimes twenty feet, break off abruptly. Where these 
veins do occur, though they are not numerous, they rather mar the 
beauty of the marble. Who first discovered this marble is not known, 
and it is of little consequence to inquire. Numerous attempts were 
made to work it, but without profit, until the present company re- 
ceived it. 
" The following exhibits the amount of stone which the Glen's-Falls 
Company have prepared and sent to market during the last four years. 
The company run 16 gang of saws, which are equal to about one hun- 
dred and sixty single saws. 
In 1835, 2,157 feet, or 32,000 pounds. 
1836, 19,800 " 278,500 « 
1837, 23,400 " 333,900 " 
1838, 25,000 " 352,500 " 
" It is remarked farther by Mr. Roberts, the agent of this company, 
that the Glen's-Falls marble has gained a good reputation with most of 
the workers of marble in New- York, Boston and Philadelphia, as it 
regards its colour, the polish which it receives, and the ease with w^hich 
it works; and that it is considered equal to any of the kind in this 
country. 
" He states that they have got out shelves for mantels seven feet and six 
inches long, thirteen inches wide and one and a quarter thick, which sells 
for sixty-five cents per foot. The price for this kind of stuflfhas fallen, 
and at the present is worth from fifty to fifty-five cents per foot; that 
which is shorter J from thirty to forty." 
There are some considerations in relation to the marble business, 
which are necessary to be understood by those who are disposed to en- 
gage in it.
