QUARTZYTES AND SANDSTONES. 59 



boiler-house stands close to the quarry. A side track about 200 yards 

 in length connects the quarry with the main line of railroad. 

 Very little trouble is experienced from water, and a brook near by 

 supplies the necessary water for the boiler. By means of a channel- 

 ling machine the sides of the quarry are cut down, and the blocks are 

 split apart by plug and feather wedges. The blocks cut apart in this 

 way are lifted by wedging them off the bed. Blocks as large as can 

 be conveniently handled, can be obtained. The stone is suited to 

 fine dressed, ornamental work or for heavy masonry, but care is 

 needed to select stone free from seams and from shale pebbles. The 

 Granby stone is being used in the building of the Second National 

 Bank of Oswego, now in course of erection. And it has been put 

 into the Protestant Episcopal church edifice and ten store buildings 

 in Cortland. 



Camden, Oneida County. — A sandstone, presumably in the 

 Medina formation, is quarried in this town, for local use. It is light 

 gray in color, and coarse-grained. The greater part of the stone is 

 used for flagging. Some of it is shipped to Oswego. 



The Medina sandstone formation has yielded some building stone in 

 the town of Sterling in Cayuga county, and in Wolcott in Wayne 

 county, but the quarries there opened have been worked for local use 

 only and to a small extent. A little stone has been taken out in 

 Penfield, Monroe county, but the Genesee river marks the eastward 

 limit of the more extensive quarry district in this formation. 



Medina sandstone, in its more restricted sense, is quarried near 

 the line of the Erie canal, from Brockport, in Monroe county, 

 west to Lockport, in Niagara county. At Rochester the Genesee 

 gorge exposes to view the sandstone, and formerly some stone was 

 quarried in the city.* Of late years it has been neglected, and the 

 stone from the quarries further west has been used in its place. 



Brockport. — Two quarries are opened at this place. They are 

 owned by Geo. Coon and Hugh Quinn. 



Holley, Orleans County. — There are three quarries in opera- 

 tion near Holley station on the N. Y. Central railroad. The quarry 

 of Gorman & Slack is nearest to the station, and on the south side of 

 the Erie canal. It is opened in a level country and adjoins the canal.
