QUARTZYTES AND SANDSTONES. 71 



and mottled stone is here, on an average, 10 feet thick. A railway 

 track one mile in length connects these quarries with the main line of 

 the N. Y. Central railroad in the town. 



Sandstone of the Clinton Group. 



This formation furnishes a building stone in Herkimer and Oneida 

 counties, south of the Mohawk valley and east-south-east of Oneida 

 lake. There are quarries in the towns of Frankfort, New Hartford, 

 Kirkland and Verona. Utica uses the largest part of the stoue from 

 the quarries at Clinton and those on Frankfort Hill. The Frank- 

 fort Hill stone is of dark-gray to red -brown shades of color, medium 

 fine-grained and hard to dress. It is largely used for foundation 

 walls. It is seen in the walls of the Grace P. E. church on Genesee 

 street, and in the Lutheran church on Columbia street. At Clinton 

 sandstone is quarried by Charles Dawes, John McCabe and Michael 

 McDermott. In Verona a small quarry has been opened near the 

 line of the N. Y. C. E. R. The stone is in thin beds and is gray in 

 color. The Rome railroad depot is built of this stone. 



At Higginsville an old quarry has been reopened this season by a 

 Utica company, and preparations have been made to do a large 

 business. The locality is on the line of the old Oneida canal and 

 fi\e miles from the Central railroad. There is a light covering of 

 sand on the stone. The upper beds are thin ; they increase as they 

 get down ; and at the bottom there is a bed four and a half feet thick. 

 The stone is dark-gray to olive-green in color ; some in the top beds 

 is reddish-brown. It is hard and is not split easily. About 12 

 feet of the stone is above the natural drainage. The place has been 

 opened forty years, and most of the stone has been used in Rome. 

 Latterly some of it has been tried in Utica, and it has given satisfac- 

 tion. It looks especially well when used with limestone trimmings 

 or with Massachusetts red sandstone. A fine example of the stone 

 is the Gilbert mansion on Genesee street in that city, which was erected 

 seven years ago.

Hudson River Blue-stone, 



The term " Hudson river blue-stone " is used to designate the blue, 

 fine-grained, compact and even-bedded sandstone, which is so largely 

 employed for flagging in New York, and more or less in all of our 

 Atlantic coast cities and towns. It is extensively used for house
