The production of 532,884 short tons of rock gypsum, reported 

 by the mines and quarries for 1913, was the largest on record. In 

 1912 the output was 506,274 tons and in 191 1, 446,794 tons. Up 

 to the year 1900 the average annual output was less than 50,000 tons, 

 and the output in the entire country previous to that time did not 

 reach the quantity reported by the New York mines for last year. 



Few changes occurred in the list of active mining companies in 

 1913. The number of mines and quarries under operation was nine 

 as compared with ten in the preceding year. In Onondaga county 

 the Fayetteville Gypsum Co., which formerly worked the Severance 

 quarry, discontinued production ; the Akron Gypsum Co., of Akron, 

 Erie county, also went out of business. The property of this com- 

 pany has been taken over by the Akron Gypsum Products Corpora- 

 tion of Buffalo, and the mines and mill will probably resume activity 

 during the current season. At Union Springs, Cayuga county, the 

 quarries were operated by the Cayuga Gypsum Co., for the supply 

 of rock to the portland cement trade, and mainly to the plant of 

 the Cayuga Portland Cement Co., at Portland Point, to which the 

 rock is shipped by rail. The mill of the Consolidated Wheatland 

 Plaster Co. near Mumford, was destroyed by fire in the spring of 



I9I3- 



No further progress has been made with the construction of the 

 calcining plant at Mumford undertaken by the Delac Gypsum Prod- 

 ucts Co., as mentioned in the report for 1912. The company had 

 secured options on gypsum lands north of Mumford which it had 

 prospected with the diamond drill. 



The search for new deposits has been carried on recently in the 

 section west of Akron. It is reported that a test hole located near 

 the limestone quarries, just southwest of the village, encountered
