beds at the base of the Salina. A similar material occurring in 

 the Catskill series has been worked at Roxbury, Delaware co. 

 The red slate of Washington county, which belongs in the Cam- 

 bric, is also ground for paint. The Algonquin Red Slate Co. of 

 Worcester, Mass., and A. J. Hurd of Eagle Bridge produce this 

 material. 



A product known as mineral black is made by grinding slate 

 found in the Hudson River series. 



The ferruginous clay called ocher occurs quite commonly in 

 the State, but no deposits are exploited at present. A bed occur- 

 ring on Crane mountain, AVashington co., once supplied a con- 

 siderable quantity. 



Sienna, a variety of ocher, occurs near Whitehall. The de- 

 posit is a thin stratum in glacial drift and has been worked on 

 a small scale. 



In addition to the producers above mentioned, the Clinton 

 Metallic Paint Co., of Clinton, and the William Connors Paint 

 Manufacturing Co., of Troy, are engaged in the manufacture of 

 mineral paints from New York materials. 



The production of mineral paints in 1907 was as follows: 

 metallic paint and mortar color, 5269 short tons valued at 

 $59,521 ; slate pigment, 620 short tons valued at $3700. In the 

 year 1906 the following quantities were reported : metallic paint 

 and mortar color, 2714 short tons valued at $29,140; slate pig- 

 ment, 2045 short tons valued at $15,960. These quantities in- 

 clude only the output made within the State from local materials. 

 A part of the ore and rock is shipped each year to points outside 

 of the State for manufacture. An output of 9667 long tons 

 valued at $24,185 was reported in 1907 by four firms who sell 

 the crude ore or rock to paint grinders. In the preceding year 

 the corresponding total was 9382 tons valued at $22,949. 



MINERAL SPRINGS 

 The mineral springs of New York afford a variety of waters 

 suited for medicinal and table uses. There are over 200 springs 

 in the State that have been listed and classified according to the 

 nature of their dissolved mineral ingredients, though many have 

 no commercial application, except perhaps for local consumption. 

 Some of the spring localities — like Saratoga SjM-ings, Ballston 

 Springs and Richfield S])rings — are popular resorts during the 

 summer season and in this way the waters afford an indirect but 

 very important source of income.
