of ground, about 15 of which are underlain by gypsum. This 

 property is not worked at present, and the company is using 

 calcined plaster from Oakfield N. Y. % 



The quarries of Mr C. A. Snooks occupy about 3 acres. The 

 beds are about the same as those on the adjoining hill. The 

 product is used by local mills entirely. 



Jamesville. In the quarry of E. B. Alvord & Co., of James- 

 ville, the rock is quarried by the use of hand drills. The explosive 

 used is black powder. The mill has a capacity of about 25 tons 

 in 10 hours. The equipment consists of a cracker and burstone 

 mill. The power is furnished by a 70 horse power turbine. This 

 mill has been run by the present owners since 1869, but the date 

 when gypsum was first dug at this place was much earlier. The 

 entire product of the quarry is used for land plaster. 



Marcellus. Near the station a small quarry is worked by 

 Mr Walker. The product is used entirely in the immediate local- 

 ity. The annual output does not exceed 500 tons. 



In grading for a trolley line from Marcellus station to the 

 village an outcrop of plaster rock was exposed in 1900 near the 

 station. The outcrop is about 20 feet thick and extends along 

 the road about 160 feet. The rock shows layers of white fibrous 

 gypsum at intervals ranging from 3 to 12 inches. These 

 layers are from J inch to 1 inch in thickness. The main rock 

 does not seem so solid as the material found at Union Springs 

 au'd Fayetteville, but should make a fair land plaster. The bed 

 seems to be quite extensive, judging from the fact that it is found 

 at the same horizon just across the valley. Outcrops of the same 

 bed are to be seen between Marcellus Station and Fairmount in 

 the hill at the south of the railroad, and it is said that many 

 thousand tons of this material were taken out when the New York 

 Central Railroad was being put through. 



Syracuse. Two and one half miles south of Syracuse gypsum 

 was formerly quarried by A. E. Alvord, but the bed became 

 exhausted, and no work has been done since 1001. 



Phelps. Mr A. D. Miller has for many years operated a quarry 

 at this place; his only product is land plaster. The quarry is on
