DESCRIPTIVE NOTES OF QUARRY DISTRICTS AND QUARRIES 275 



facturing Company's quarry is two miles west of Rock Glen, 

 on the New York, Lake Erie and Western railroad. It was 

 opened many years ago, but was idle in 1888-9. Some of 

 the stone in the city hall, Rochester, was taken from this 

 quarry. The Warsaw Blue Stone Company's quarry is lo- 

 cated one-half mile from Rock Glen station, and south of 

 Warsaw ; a side track runs from the quarry to the main 

 line of the New York, Lake Erie and Western railroad. 

 The Warsaw bluestone is very fine-grained, harder than the 

 Ohio sandstone, and retains its color on exposure. It has 

 been used for more than thirty years, in Warsaw and vicin- 

 ity, for monumental bases and buildings. 



A specimen from the company's quarry showed a specific 

 gravity of 2.681, equivalent to a weight of 167 pounds per 

 cubic foot. It contains 3.22 per cent of ferric oxide and 

 0.23 per cent of ferrous oxide. The absorption test gave as 

 a result 2.99 per cent ; the freezing and thawing tests pro- 

 duced slight checking. At the high temperature (1200^- 

 1400° F.), there was a slight vitrification, somewhat of 

 checking, and the color was changed to dull red. The 

 quarrying plant has been largely increased, and the machin- 

 ery for sawing and dressing the stone has been set up. The 

 output during the year 1889 ^^^ largely in excess of that of 

 any previous year. The principal use of this stone is for 

 house trimmings. The markets are New York city, Syra- 

 cuse, Elmira, Corning, Binghamton, Philadelphia and 

 Washington. The Alpine, corner of Sixth avenue and 

 Thirty-fourth street. New York city, the United States 

 Government building, Binghamton, and the Colgate Library 

 building, Hamilton college, are more prominent examples 

 of the Warsaw bluestone.
