THE MINING AND QUARRY INDUSTRY 1912 75 
Erie county outranks all others in importance in this industry; 
its products are chiefly furnace flux, crushed stone and building 
stone. The value of the limestone quarried within the county last 
year was $923,847. The larger quarries are at North Buffalo, 
Clarence and Akron. 
Onondaga county occupies second place, the result mainly of the 
operations of the Solvay Process Co., with its quarries at James- 
ville which are among the largest and best equipped of any in the 
country. Besides the stone used by the company in the alkali works 
at Syracuse, it sells a large quantity for road making, cement and 
other purposes. The Lackawanna Stone Co. has quarries under 
development which will probably enter upon active production dur- 
ing the current year. 
The other counties reporting a value of over $100,000 in 1912 
were Dutchess, Rockland, Ulster, Genesee, Warren, Niagara, Al- 
bany and Schoharie, ranking in the order named. A large quarry 
to furnish flux is being opened near Gasport, Niagara county. This 
locality lies on the outcrop of the Clinton formation, the same as 
the flux quarry near Pekin, a little farther west. The quarry is 
to be operated by the Wickwire Limestone Co. It is reported that 
a limestone quarry is under development at Oriskany Falls, by 
Bardorf, Davis & Chapman. 
The distribution of the limestone according to counties and also 
according to uses is shown in the accompanying tables for the years 
I9Ii and 1912. 
Crushed stone. Limestone finds its principal application as 
crushed stone in which form it is employed for road metal, concrete 
and railroad ballast. There are large quarries supplying crushed 
stone in Erie, Genesee, Dutchess, Ulster and Rockland counties, as 
well as many smaller quarries in other counties. The canal, highway 
and other public improvements in current progress have created 
large markets for the material and the production has shown a 
steady increase. A considerable quantity of the fines made by the 
crushing plants is sold for agricultural purposes as a substitute for 
burnt rock or lime. 
The value of the crushed limestone for 1912 reached a total of 
$2,176,308 against $1,936,292 for the preceding year. As stated 
already, the total does not include the stone crushed by contractors 
for local use on the highway system. The actual quantity turned 
out by the crushing plants was 3,559,257 cubic yards, as compared 
with 3,116,958 cubic yards in t911t. Erie county alone made an out-
