THE MINING AND QUARRY INDUSTRY IQI2 35 
The large quarries at Union Springs, Cayuga county, were not 
active in 1912, but have recently been taken over by the Cayuga 
Lake Portland Cement Co. for supply of gypsum to their works at 
Portland Point, near the southern end of Cayuga lake. After pump- 
ing out the quarry pit in the spring, active shipments were begun 
about June Ist. The gypsum is rather low grade, but constitutes such 
a thick series of beds that it can be extracted very cheaply, and the 
situation is convenient for shipment to the portland cement plants 
of eastern Pennsylvania. The rock is taken from the quarry to a 
mill at the lakeside when it is crushed and loaded into cars. 
The mines of Monroe county increased their production during 
the year, but there was little change otherwise in that section. 
The county ranked second to Genesee in quantity of rock mined. 
About two-thirds of the total was calcined at the mines and the 
rest sold crude to portland cement makers, or ground to land plaster. 
The Lycoming Calcining Co., the Consolidated Wheatland Plaster 
Co., and the Empire Gypsum Co. operated calcining plants, while 
the Oatka Gypsum Co. sold all its output in crude form. 
At Mumford, the Delac Gypsum Products Co. did some pros- 
pecting and started construction work on a mill for the manufac- 
ture of the calcined plasters. The company secured options on the 
M. Skivington farm north of Mumford, where five test holes were 
drilled, in all of which gypsum was found. A hole located near the 
southern end of the property on the flat along Allen creek gave 
the following section, according to records in possession of Mr 
Skivington : ;
