inches thick ; then, one 18 inches thick ; a third one 6 inches thick ; 

 and the bottom, 7 inches. These two lower beds alone are worked 

 for cut and dimension stone, and the heavy beds at the top go into 

 flagging material. The stone is sold at the quarry at 25 to 40 cents 

 per square foot, according to size. The lower bed is cut for coping 

 10 inch and 7 inch, and is fine-pointed and sells at about $1 a running 

 foot. The product of the quarry, as now worked, is largely put into 

 the market for house-trimmings. A part of it, however, is used for 

 cemetery work. 



Nearer the village and near the water the top beds are well ex- 

 posed on the surface ; and Barron has opened the locality and worked 

 a 10-inch layer, which appears to be equivalent to the 6-inch and 

 7-inch layers at the southern quarry. A few rods north-east of Bar- 

 ron's house there is an abandoned quarry, where the beds are thick, and 

 the stone strong and solid ; and it was once worked for bridge stone. 

 The drainage at these openings is natural, and there is no machinery 

 employed. The markets for the stone are Watertown and points on 

 the lake shore. 



Chaumont, Jefferson County. — The following quarries are 

 opened in and near the village of Chaumont : 



Copley's quarry, worked for lime ; the quarry of Belden, John- 

 son & Company, of Syracuse, on the shore of the lake ; the quarry of 

 Adams Brothers ; the quarries of Du Fort & Son, on land of H. 

 Copley. 



The quarry of Belden, Johnson & Company, on the bay, has a 

 working face of 500 feet in length from north-east to south-west, and 

 a breadth of 100 feet, at least, at the eastern end. The main joints 

 run, vertically, south 82° west and north 25° west. The strata dip 

 slightly, westward. The upper beds of rock are somewhat irregular, 

 and, in part only, available for building, stone. It answers, however, 

 for common walls, and is 8 to 9 feet thick. Under it there are four 

 feet of thick beds for cutting and dressing. Next below, follows a 

 thin and irregular layer, a foot thick : then, the gray, sub-crystalline 

 limestone, in beds, 6, 6, 12 and 8 inches thick, or in all, 2 feet 8 inches. 

 At the west end the dip carries the beds below the lake level, neces. 

 skating some pumping. This quarry is worked at intervals by 

 Adams Brothers. 



The main quarry of Adams Brothers is on the bay shore, in the vil- 

 lage. The quarry face is at least 600 feet long (from east to west),
