DESCRIPTION OF MARBLE AND LIMESTONE QUARRIES 441 



Watertown, Jefferson County. — The gray of the Trenton and 

 the heavy beds of the Black river limestones are finely exposed 

 to view in the gorge of the Black river at Watertown. They are 

 not worked. 



Three Mile Bay, Jefferson County. — At this place the lime- 

 stone is so thinly covered as to be readily opened, and stone for 

 local use is obtained in several small quarries. Barron's quarry 

 is close to the lake shore, and half a mile from the railroad 

 station. 



The lower beds are worked into cut stone for house trimming 

 and cemetery work. "Watertown and the lake ports are the 

 chief markets. 



At Brownsville some limestone is quarried at the side of the 

 Cape Yincent branch railroad for local use. 



Chaumont, Jefferson County. — There are several large quarries 

 at Chaumont, two of which, Adams Bros, and Duford & Sons, are 

 run steadily. The former has a quarry face a mile in length. 

 They are in the horizon of the Black river and Trenton limestones. 

 The beds dip westward at a small angle and are divided into 

 large blocks by vertical joints. 



There is a blue limestone at the top which is made into lime, 

 or used for common wall work. Under it is the gray sub-crystal- 

 line variety, in what are known as the 32-inch and the 16-inch 

 beds, besides thinner beds lower down. The surface courses 

 furnish stone for lime manufacture. The stone of the thicker 

 beds is cut for lock facing and bridge work ; the thin beds are 

 worked into house trimmings. These quarries are on the shore of 

 the bay, convenient to navigation and are near the railroad also. 

 The product is increasing from year to year. Much of the 

 Chaumont stone has been put into Erie canal locks. 



The Protestant Episcopal Church, the County Clerk's office and 

 City Opera House in Watertown are examples in construction. 



Oswego, Fulton and Utica are other markets. 



Ogdensburg, St. Lawrence County. — The number of stone 

 buildings in Ogdensburg is comparatively large, and the material 

 is almost all out of local quarries in the Chazy limestone formation.
