136 Report on Building Stone of New York. 



Kays' Quarry also is in the town of Salem, and on the Christopher 

 Morey farm, in the Black creek val.ey, and four miles north-west of 

 Salem. It was opened in April, 1886, by Hugh Kays, of Salem. 

 The opening is 60 x 40 feet, and 45 feet deep. The slate is red and 

 is said to be quite as deep-colored as that of Granville. 



In what may be the same range (or " vein " of the slate quarry- 

 men), there is the Douglass quarry, which is located about three and 

 a half miles south-south-west of Granville and near Slateville, in the 

 town of Hebron. It produces a red slate. During the past season 

 it was idle. 



Granville. — The Granville red-slate vein or range is traceable for 

 two miles northward from Granville, east of Middle Granville, and 

 nearly parallel to the Vermont line. It is narrow, in places not over 

 30 rods wide, and its surface very rocky. The strata crop out in numer- 

 ous low, glaciated knobs and ledges. Quarries and trial pits have 

 been opened at many points. The following quarries are noted here, 

 beginning at Granville : 



The quarry of Evan J. Roberts and John Hughes is in the northern 

 part of the village of Granville, and about 100 feet west of the Mid- 

 dle Granville road and the D. & H. R. R. line. The opening is 150 

 x 45 feet, and 20 to 30 feet deep. The beds dip 50° south 82° east. 

 One system of joints runs north 85° west and is vertical ; a second^ 

 has its joint faces dipping 40° west. The covering of earth on the 

 slate rock at this opening, was not more than two feet thick at any 

 point, and the rock, as seen in the outcropping ledges near the 

 quarry is solid and hard. Some white calcite and milk-white quartz 

 are seen in the joint surfaces. The cleavage coincides with the dip 

 of the beds. The varieties of slate here obtained are green and red. 

 The red slate is fine-grained, homogeneous and bright-red in color. 

 There is one derrick on the dump, at the south end. The quarry has 

 not been in operation during the past season. 



Going north on the line of the red-slate " vein" the next opening 

 is about 120 rods to the north, and 40 rods east of the railway. It 

 is small and at present, partly filled with water. 



The quarry of John J. Williams is north of the last mentioned 

 locality, and on a ridge about 50 feet above the Granville terrace, 

 and perhaps 80 rods from the railroad. The opening is 100 feet long 

 and nearly as wide. The depth averages 50 feet. The beds dip 40° 

 east-south-east. One well-marked joint system runs east and west. 

 The second is less plainly marked, at right angles to the first ; and
