and is 17 feet high ; and the order of the strata, from the top is as 

 follows : 



1. Dark-blue limestone 8 to 10 feet. 



2. Gray limestone (32-inch layer) 2 feet 8 inches. 



3. Gray limestone (16-inch layer) 1 foot 4 inches.

The seams or joints in this quarry are remarkable for their regu- 

 larity, and they are a great help in quarrying. One set or system runs 

 south 80° west, and dips 80° to 85° southward ; a second system 

 runs south 10° west, vertically. They are from five to fifteen feet 

 apart. The dark-blue stone of the upper part is burned into lime, at 

 the quarry kilns. The gray stone of the 32-inch and 16-inch 

 courses or beds, are dressed for lock-facing stone, or are cut for monu- 

 mental work. The gray limestone of the bottom (4, of section) is 

 cut into sills, lintels, water tables, etc., for house trimmings. This 

 quarry has been opened four years. An example in construction, of 

 this stone, is seen in the Protestant Episcopal^ church building in 

 Watertown. The quarry is within a half a mile of the R. W. & O. 

 R. R. station. 



South of the village, and on the east side of the little bay, are the 

 quarries of Davis, aud Du Fort & Son. The Davis quarry is about a 

 quarter of a mile from the village. Blue limestone is seen at the top, 

 then the 32-inch bed and the 16 inch bed, and under them the gray 

 limestone. An area of 600x200 feet is here opened and worked 

 over. This quarry is run at intervals. 



Du Fort & Son's Quarry is south of the last named, and a half a 

 mile south of the village, and three-quarters of a mile from the rail- 

 road station. It is on the shore of the lake ; and at the dock near the 

 quarry there is a depth of 12 feet of water. The several beds are 

 shown by the following sections : 



1. Blue limestone 3 feet. 



2. Gray limestone (32 in. layer) 32 inches.
