Crude clay 



In the foregoing tables relating to clay products no account has 

 been taken of the crude clay entering into their manufacture. There 

 are a few producers in the State who do not utilize the crude clay 

 ^ themselves, but ship their output to others for manufacture. Some 

 of the material, like the Albany slip clay for example, is even for- 

 warded to points without the State. In 1906, returns were received 

 from four firms engaged in this industry whose total shipments 

 amounted to 5477 short tons valued at $9125. The corresponding 

 total for 1905 was 6766 tons with a value of $16,616 and for 1904 

 8959 tons with a value of $17,164. 



EMERY 



The emery deposits near Peekskill were worked on about the 

 usual scale during the past year. The output reported by the four 

 producers that were active amounted to 1307 short tons valued at 

 $13,870. This compares with a total of 1475 tons valued at $12,452 

 in 1905 and 1148 tons with a value of $17,220 in 1904. The valua- 

 tion is based on the crude material as it comes from the quarries 

 where it undergoes only a rough sorting before shipment. The 

 lump emery is sent to outside points for grinding and manufacture 

 into emery wheels, stones, cloth, etc. 



The list of producers in 1906 includes the following : Blue Corun- 

 dum Mining Co., Easton, Pa., Keystone Emery Mills, Frankford, 

 Pa., J. R. Lancaster, Peekskill and the Tanite Co. Stroudsburg, Pa. 

 The Keystone Emery Mills have taken over the properties formerly 

 worked by H. M. Quinn. With the exception of J. R. Lancaster 

 who sells his product to .the Hampden Corundum Wheel Co., of 

 Springfield, Mass., the companies mine the emery for their own 

 consumption in connection with manufacturing plants. 



FELDSPAR 

 The quarries of feldspar at Bedford, Westchester co., were 

 operated as in previous years by P. H. Kinkel of that place and 

 yielded their average output. In connection with the working of 

 the quarries a considerable quantity of quartz, or flint as it is com- 

 monly termed, was obtained. The feldspar was shipped to Trenton, 

 N. J., where it is employed in the manufacture of porcelain wares. 

 An additional source of supply for the mineral received attention 

 during the past year, the locality being in Washington county, 

 about 3 miles north of Fort Ann. The feldspar is found here in
