The quarry localities are at Shushan ; Salem ; Black 

 creek valley, in the town of Salem ; Slateville, in Hebron ; 

 Granville ; the Penrhyn Slate Company's quarries, Middle 

 Granville ; Mettowee or North Bend quarries ; and the 

 Hatch hill quarries, in East Whitehall. 



The quarries of Washington county have not yet been 

 worked down to as great depth as some of those in North- 

 ampton and Lehigh counties, in Pennsylvania; and the 

 deepest has not reached a vertical depth of one hundred 

 feet. 



The quarries at the south-west, in Shushan and Salem, 

 produce purple, variegated, and green colored slates. At 

 Salem some stone for flagging and foundation work is ob- 

 tained. At the quarries west and north-west of the village 

 of Salem, and at Slatesville, in Hebron, the slate is red. 



The principal range of red slate is that which runs from 

 Granville north — passing east of Middle Granville. It is 

 narrow, being in places less than thirty rods wide. There 

 are numerous openings in it, and it has yielded a large 

 amount of red, and some unfading-green, roofing slate. 



In Middle Granville the purple, green and variegated va- 

 rieties are found. North of the village, a quarter to three- 

 quarters of a mile, are the large openings of the Penrhyn 

 Slate Company, which produce purple, unfading-green, and 

 variegated (green and purple) slates. A large part of the 

 output of these quarries is worked up in their mills Into 

 plain, marbleized, decorative and enamelled material, as 

 mantels, steps, house trimmings, table tops, laundry tubs, 

 wainscoting and floor tiles. 



The Mettowee or North Bend quarries, three and a half 

 miles north of Middle Granville, are worked by two compa- 

 nies. Their product is a red roofing slate. 



The Hatch hill group of quarries is six miles south-east 

 of Whitehall. There are four openings. 



The slate is of a bright-red color. A part of it is split 

 at the quarry into roofing material. Perhaps an equally
