stone for flagging and foundation work is obtained. At the 

 quarries west and northwest 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 Gran-, 

 ville 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 varieties 

 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 

 enameled 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 companies. Their 

 product is a red roofing slate. 



The Hatch Hill group of quarries is six miles southeast 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 large amount 

 is cut into floor-tiling, billiard table tops and house trimming 

 materials. These quarries are much deeper than those of the 

 Granville red slate range, and the slate has a brighter red color, 

 and is more easily worked than that of the latter range. 



Their product, mostly finished stock, has to be carted by teams 

 six miles to Whitehall or to Middle Granville, shipping points. 



The green slate of these Washington county quarries is almost 

 all of the unfading variety, which is more durable and more valu- 

 able than the sea green slate. The variegated (purple and green) 

 also is durable, but is softer and less valuable than the red, which 

 is esteemed for roofing and tiling purposes. 



The purple and green slates are more abundant, and are used 

 more for marbleizing. 



A specimen of the red roofing slate of Washington county was 

 tested and found to have a specific gravity of 2.84, equivalent to 

 a weight of 177 pounds per cubic foot. It contained 1.87 per
