in the returns, with Onondaga county in the lead, though 

 its output consisted mostly of salt used for soda manufacture. 

 Livingston county made the largest quantity of marketable 

 grade, chiefly rock salt. 



An aggregate of 323,323 short tons of gypsum was taken from 

 the mines and quarries of the State last year, as compared with 

 262,486 short tons in 1906. The output has increased by over 

 100 per cent within the last three years, due to the rapid de- 

 velopment of the trade in wall plasters, stucco, etc., and to the 

 use of gypsum in Portland cement manufacture. The value of 

 the different materials was $1,038,355, as compared with $699,- 

 455 in 1906. 



The combined value of the petroleum and natural gas pro- 

 duced in the State was $2,536,349, a small increase over the value 

 reported for 1906 which was $2,487,674. The quantity of petro- 

 leum taken from the wells, estimated from the receipts of pipe 

 line companies, was 1,052,324 barrels, valued at $1,736,335, or 

 nearly the same as in the preceding year. The natural gas pro- 

 duction was valued at $800,014, as compared with $766,579 in 

 1906; the volume amounting to 3,052,145,000 cubic feet against 

 3,007,086,000 cubic feet in the preceding year. New discoveries 

 of gas continue to be reported and the additional supplies thus 

 made available have more than sufficed to maintain the rate of 

 production. 



The mining of pyrite showed a notable advance during the 

 past year, the output amounting to 49,978 long tons, which com- 

 pares with 11,798 tons for 1906. The mineral is obtained in St 

 Lawrence county. A large amount of exploratory and develop- 

 ment work has been done recently, with results that may lead 

 to a further expansion of the industry. The product finds a 

 ready sale for making sulfurous and sulfuric acids. 



The talc mines near Gouverneur contributed a production of 

 59,000 short tons, or a little less than in 1906. The value of the 

 output was $501,500. The production is governed chiefly by 

 the requirements of the paper trade and show^s little tendency to 

 fluctuate from year to year. 



Garnet for abrasive uses is obtained from the eastern Adiron- 

 dacks. An output of 5709 short tons valued at $174,800 was 

 reported in 1907. The returns for the preceding year showed an 

 output of 4729 short tons with a value of $159,298. 



The crystalline graphite mined in the Adirondacks amounted 

 to 2,950,000 pounds, against 2,811,582 pounds in 1906. The value
