amounted last year to $2,745,945, against $2,869,893 in 1910. The 

 decline in value was due to the smaller prices secured for petroleum, 

 which more than counterbalanced an increased production of natural 

 gas. The total quantity of oil produced was 915,314 barrels valued 

 at $1,198,868, as compared with 1,073,650 barrels with a value of 

 $1,458,194 in 1910. The gas production was 5,127,571,000 cubic 

 feet with a value of $1,547,077 against 4,815,643,000 cubic feet 

 valued at $1,411,699 in the preceding year. 



Among the smaller industries in which local enterprise has a promi- 

 nent share may be mentioned those of talc, garnet, graphite, and 

 pyrite. The talc is mainly produced from a single district in St 

 Lawrence county, which enjoys a practical monopoly of the trade 

 in fibrous talc. The production last year amounted to 65,000 short 

 tons valued at $552,500, or about the same as in 1910. Garnet for 

 abrasive uses is obtained in Essex and Warren counties, and the 

 quantity reported for last year was 4285 short tons with a value of 

 $121,759. The graphite, all of it the more valuable crystalline 

 variety, amounted to 2,510,000 pounds valued at $137,750, a little 

 under the previous year's total. Pyrite for acid manufacture was 

 produced to the extent of 53,453 long tons valued at $251,466. 



The remaining mineral materials which had a place in the list of 

 products for last year were apatite, carbon dioxid, clay, diatoma- 

 ceous earth, emery, feldspar, marl, millstones, metallic paint, mineral 

 waters, slate pigment, quartz, slate, sand, sand-lime brick and zinc 

 ore. The collected value of these materials was $3,052,143, against 

 $3,579,488 in 1910. 



It is worthy of record that a new industry so far as concerns New 

 York State came into existence during the year with the shipment 

 of zinc ore from St Lawrence county, where some promising 

 developments have been in progress.
