section. The manufacture of wall plaster is carried on principally 

 in the vicinity of Syracuse, Onondaga co., at Wheatland and Gar- 

 butt, Monroe co., and at Oakfield, Genesee co. 



The output of gypsum in crude form during 1906 amounted to 

 262,486 short tons, reported by 16 producers. In 1905 the output 

 was 191,860 short tons and in 1904 it amounted to 151,455 tons. 

 The greater part of the output was converted into wall plaster and 

 plaster of paris, the combined product of these materials amounting 

 to 163,451 short tons valued at $595,285 against 130,268 tons valued 

 at $478,084 in the preceding year. The totals include only the 

 quantities made from gypsum mined or quarried in the State ; in 

 addition there is a production of wall plaster and plaster of paris 

 from imported material for which no returns are received. The 

 quantity of gypsum that was ground and sold for land plaster 

 amounted in 1906 to 20,656 short tons valued at $46,094, against

Unusual attention has been given during the past year to the 

 exploration of the gypsum deposits of the State, with results that 

 promise to contribute toward the further expansion of the industry 

 in the immediate future. In Onondaga county a new company has 

 been engaged in the development of a deposit near Jamesville. A 

 vertical shaft was put down to a depth of 100 feet and encountered 

 about 40 feet of gypsum at the bottom. The Lehigh Portland 

 Cement Co. and E. B. Alvord & Co. were active in exploring for 

 deposits in the same district. The American Gypsum Co. has 

 developed a property near Alabama, Genesee co., where the Akron 

 Gypsum Co. has also opened a deposit. The former company in-
