DESCRIPTION OF SANDSTONE QUARRIES 399 



duced no visible effect. After a subjection to a high temperature 

 and sudden cooling, the strength was but little impaired and the 

 color was slightly changed. 



These quarries employ from one hundred and fifty to two 

 hundred men each, and the aggregate product, annually, 

 amounts to many thousands of tons. The bulk of the stone 

 quarried by the Albion Stone Company, and the Goodrich 

 and Clark Stone Company, is used for street purposes, as 

 paving, curbing, gutters and crosswalks. Platforms of large 

 size, and smooth and true surfaces, are cut from some of the 

 thick beds. 



The paving blocks are sold principally to western cities — Erie, 

 Akron, Cleveland, Toledo, Columbus, Detroit, Chicago and Mil- 

 waukee. The Brady quarry produces stone for building, 

 principally. 



These quarries are conveniently located for working, at the 

 side of canal and railroad, and are well equipped for a large 

 business. 



Some examples of the Albion stone are the Presbyterian 

 church, Albion ; the Iroquois Hotel, Young Men's Association 

 building and Trinity Protestant Episcopal Church in Buffalo ; 

 Guernsey building, No. 160 Broadway, New York city ; steps of 

 the new staircase, Capitol in Albany, 



Medina, Orleans County. — Medina has given name to this 

 sandstone formation because of its development and the charac- 

 teristic fossils which are abundant in some of the gray beds at 

 this locality. Within a mile and a half of the railroad station 

 there are, north and northeast of the town, the quarries of 

 Kearney & Barrett, A. M. Hollo way, Sara J. Horan, Buffalo 

 Paving Company, Noble & Lyle and C. A. Gorman. The work- 

 ing season is naturally from the first of April to the middle of 

 November. The rest of the year is given to stripping off the 

 overlying earth and waste rock. As compared with the stone of 

 the quarries in the Medina sandstone formation, eastward, the 

 color is lighter gray, and there is the variegated, or spotted red 

 and white, and a light red. Generally it is harder. Oblique 

 lamination in the beds is more common than at Albion or Hul- 

 berton. Pyrite-coated seams and joint faces are seen, chiefly in
