Limestones. 119 



The dip of the beds is very slightly west, as shown by their pass- 

 ing below the level of the water 200 yards west of the quarry. The 

 main joint system runs south 75° to 80° west, but is not so open as 

 that in the quarry of Adams Brothers. There are two derricks for 

 hoisting stone. The drainage is natural, into the lake. Powder is 

 used for blasting off the top, blue stone, which is thrown away. The 

 32-inch and 16-inch courses are now quarried for lock construction 

 on the Erie canal. The 10-inch layer is worked into sills, lintels, 

 etc., for house trimmings, and the lower beds are used for flagging. 

 The stone from this quarry can be seen in H. Copley's office in the 

 village. At the present time the product is largely used for Erie 

 canal lock construction. 



These Chaumont quarries are, geologically viewed, in the Black 

 river and Trenton limestone. The stone of the thick courses is strong 

 and well adapted to heavy wall work. And a great quantity has been 

 sold for canal and bridge construction. It sells at $9 to $13 per 

 cubic yard. The gray stone for house trimmings brings 50 to 60 

 cents per square foot. About forty men are employed in the several 

 quarries, and the work continues all the year or whenever weather 

 permits. As they are all convenient to lake and rail the markets are 

 reached easily and cheaply. 



Limestone is quarried near Brownville at the side of the Cape 

 Yincent Branch railroad, occasionally, and for local use. 



At Watertown the limestone is finely exposed in the gorge of the 

 Black river. The strata dip at a small angle westerly. The 32-inch 

 and 16-inch beds of the Chaumont quarries are thinner here. The 

 gray stone underlies them. Up the stream and easterly the dark- 

 colored, knotty limestone is in force. 



Ogdensburg, St. Lawrence County. — Much limestone has 

 been used in building in this town, and the larger part has been 

 obtained from local quarries, in the Chazy limestone formation. The 

 elegant town hall and St. John's P. E. church are substantial and 

 beautiful examples of the stone, which is found in the valley of the 

 river, in the town. The quarry-site is built over, in part, by the Hub 

 factory. The quarry, which is now worked for local supply, is on the 

 Oswegatchie river, about two miles south of the town. 



Norwood, St. Lawrence County. — Robert Murray has a quarry 

 in the town of Norfolk, one and a half miles from Norwood station 

 of the O. & L. C. R. R. line. It is in the blue limestone. The beds
