SLATE 



The quarrying of slate in New York is restricted at present to 

 a small district in eastern Washington county. The district 

 extends north from Salem through the towns of Hebron, Gran- 

 ville, Hampton and Whitehall and is practically continuous with 

 the Vermont slate district which has attained much- greater im- 

 portance in the industry. The slate occurs in several horizons 

 among the metamorphosed Paleozoic strata of the region, but 

 belongs mostly to the Cambric and Lower Siluric systems. Ex- 

 tensive slate beds are found also in the southern continuation of 

 the metamorphic region along the east side of the Hudson river, 

 in Rensselaer, Columbia and Dutchess counties. Attempts to 

 work the slate in this section, however, have not been perma- 

 nently successful, though it is recorded that quarries were oper- 

 ated, for a tim,e at Hoosick, New Lebanon and New Hamburg. 



The slate from Washington county is remarkable for its variety 

 of colors. The red slate which is obtained near Granville and in 

 the Hatch Hill and North Granville sections has no superior for 

 beauty and permanency, while purple, variegated and different 

 shades of green slate occur in the southern section around 

 Middle Granville, Salem and Shushan. Nearly all of the product 

 is sold for roofing purposes. The manufacture of other mater- 

 ials such as mantels, floor tiling, blackboards, billiard tables, etc., 

 is not carried on to any extent in the State. 



The production of slate for the past year amounted in value to 

 $53'^-5- Of this, roofing slate represented $52,450 and mill stock 

 $1175. The number of squares of roofing slate made was 11,686. 

 In 1906 the total production was valued at $61,921 consisting of 

 16,248 squares of roofing slate valued at $57,771 and mill stock 

 valued at $4150. The average value of roofing slate for the year 

 was $4.60 a square against $3.56 a square in 1906. The increased
