in the new armory, Albany ; in the church at Menand's 

 station, and in St. Patrick's Roman CathoHc church in 

 West Troy. The stone has a bluish shade of color and 

 is fine-grained. 



DuanesburghjSchenectady County.— A quarry in a bluish- 

 colored sandstone, probably of the same geological horizon 

 as that of the Schenectady quarry, is here worked by Albert 

 Shear & Co. The stone is rather coarse-grained but is 

 stronger than the Schenectady bluestone. 



The shaly nature of much of the Hudson river group of 

 rocks in the Mohaw^k valley, west of Schenectady, and the 

 accessibility of good limestone for building purposes, has 

 prevented the opening of quarries in it. Further west, and 

 near Rome, there are small quarries which are referred to 

 this horizon, but they are unimportant. The sandstone 

 quarries in the towns of Camden, Oneida County, and of 

 Orwell, in Oswego County, belong in it. The stone is gener- 

 ally gray in color, fine-grained and hard, and in moderately 

 thick beds. None of these quarries do much more than a 

 small local business ; and they are not in operation all of the 

 working season of the year. 



Good building stone of the Hudson river horizon is said 

 to have been obtained at quarries south-east of Rome ; also 

 at Woodruff's, Oneida County.* 



Sandstone of the Medina Epoch 



Oswego, Oswego County.— Quarries for the supply of stone 

 for foundation and retaining walls in the city, are opened on 

 the lake shore, east of the Fort Ontario grounds. 



Oswego Falls, Oswego County — The river cuts through 

 the sandstone here and offers facilities for small quarrying 

 operations in the bluffs on the left bank. A dark-red sand- 

 stone is obtained under earth and shaly rock. The First 

 Presbyterian church in Syracuse is an example of badly se-
