which exceeded 20 per cent came mostly from the mines in the 

 western section where a number of new enterprises recently entered 

 the field. 



The combined value of the petroleum and natural gas produced 

 in the State last year was $2,869,893 against $3,059,308 in 1909. 

 The quantity of petroleum, all from the wells in Allegany, Catta- 

 raugus and Steuben counties, amounted to 1,073,650 barrels with 

 a value of $1,458,194. This was a reduction from the previous 

 year's total of 1,160,128 barrels attributable to the recent drop in 

 prices which discouraged exploration work. The gas wells, how- 

 ever, made a larger output than ever before, the total flow amount- 

 ing approximately to 4,815,643,000 cubic feet with a value of $1,- 

 411,699 against 3,825,215,000 cubic feet and a value of $1,045,693 

 in 1909. The Erie county wells contributed the largest increase of 

 output for the year. 



The talc industry is one of the smaller mining activities repre- 

 sented in New York and the output came mostly from a single dis- 

 trict in St Lawrence county. The amount obtained last year was 

 about 65,000 short tons, valued at $552,500, a gain of 15,000 tons 

 over the total for 1909. The St Lawrence county mines have prac- 

 tically a monoply of the fibrous talc consumed in paper manufacture. 



Garnet for abrasive uses was produced to the amount of 5297 

 short tons, valued at $151,700, a large gain over the figures reported 

 for the preceding year which were 3802 tons, valued at $119,190. 



The production of crystalline graphite from the Adirondack 

 mines amounted to 2,619,000 pounds with a value of $160,700. The 

 corresponding total for 1909 was 2,342,000 pounds with a value of 

 $140,140. 



The mineral springs that were used for commercial purposes re- 

 ported sales of 8,432,672 gallons valued at $675,034 as compared 

 with 9,019,490 gallons valued at $857,342 in 1909. 



Among the other mineral materials which had a place in the list 

 of products reported last year were apatite, carbon dioxid, clay, 

 diatomaceous earth, emery, feldspar, lead ore, marl, millstones, 

 metallic paint, slate pigment, pyrite, quartz, slate, sand and sand- 

 lime brick. The collected value of these materials was $2,004,454 

 as compared with $2,170,881 in 1909.
