amounted last year to $3,220,647. There was a material gain in the 
production of natural gas, the well flow having been 6,564,659 M. 
cubic feet against 5,127,571 M. cubic feet in 1911; but the oil 
industry was less active and returned an output of only 782,661 
barrels, as compared with 955,314 barrels. The heavy decline in 
the crude oil market in 1910 was responsible in large measure for 
the decreased output last year, as it put a check upon new drilling 
that is necessary to maintain a balance with the depletion of old 
wells. 
Among the minor industries in which New York has a prominent 
place by reason of its natural resources, are those of talc, garnet, 
-graphite and pyrite. Talc is mainly obtained from a single district 
in St Lawrence county, which has a practical monopoly of the 
fibrous talc trade. The production last year amounted to 61,619 
short tons valued at $511,437, or about the usual quantity. Garnet 
for abrasive use is produced in Essex and Warren counties, and 
the output last year was 4112 short tons with a value of $117,325. 
Graphite of the more valuable crystalline sort is found in the 
Adirondack region; the total product last year was reported as 
2,028,000 pounds and represented a value of $142,665. Pyrite for 
acid manufacture is mined in St Lawrence county. 
The remaining mineral materials represented in the list of pro- 
ducts for last year included apatite, clay, diatomaceous earth, emery, 
feldspar, marl, millstones, metallic paint, mineral waters, slate pig- 
ment, quartz, slate, sand, sand-lime brick, and zinc ore. There 
were no additions to the list during the year, but on the other hand 
one industry — that connected with the production of carbon dioxid 
from natural sources — was discontinued as the result of the recent 
action taken for the conservation of the Saratoga mineral waters.
