when wet. The Normal school buildings, the town hall, 

 the Cox block, and the Presbyterian, Universalist and Epis- 

 copal churches are the more prominent structures of this 

 stone in Potsdam. In the last-named church there is much 

 carved work, making it very expensive on account of the 

 hardness of the stone. 



The Potsdam stone finds a wide market, and the demand 

 for it is growing, as its beauty, strength and durability are 

 better known and appreciated. 



On account of its hardness, and the cost of fine-tool 

 dressing, the stone is best adapted to rock-face, ashlar work. 

 It may be seen in the '' Florence," South Salina street, 

 Syracuse ; All Saints' cathedral, Albany ; Columbia college 

 and Rutgers Protestant Episcopal church. Seventy-second 

 street. New York city ; Reid building, Seventh avenue and 

 Sterling street, Brooklyn ; the State asylum, at Matteawan ; 

 the New York State asylum and City opera house, Ogdens- 

 burg ; and in the Dominion Parliament buildings at Ottawa, 

 Canada. 



Hammond. St. Lawrence County.— Sandstone is quarried at 

 three localities in the town of Hammond, and on the line of 

 the Rome, Watertown and Ogdensburgh railroad. The 

 stone lies in beds which dip about 5^ eastward and, owing 

 to the well-defined joints and the evenness of the bedding, 

 blocks are worked out readily which are suitable for cutting 

 into curbing and flagging stone, or for making paving 

 blocks. Its color is gray-white — in places striped, red and 

 white. It is hard, and is nearly all silica. Unlike the quar- 

 ries at Potsdam there is little earth covering, and the beds 

 worked are not deep. 



The output of the Hammond quarries is nearly all con- 

 sumed in street work, and goes to Utica, Syracuse, Rome,^ 

 Binghamton, Ogdensburg and to western cities. 



Clayton, Jefferson County.— The Potsdam sandstone forma- 

 tion crops out at Clayton, and affords a hard and durable 

 stone for local demands.
