The sandstone of Orange county, Ind., furnishes a whet- 

 stone known as the Hindostan or Orange stone, which is quar- 

 ried in French Lick and Northwest townships. The stone is fine 

 grained and is used for oilstones. It is considered the best 

 low priced sharpening stone for mechanics' tools. A consider- 

 able quantity of this stone is now being exported. 



In Haverhill, Grafton county, N. H., and near Lamoille, 

 Orleans county, Vt., there is a quartz-mica-schist from which 

 are manufactured the celebrated Indian Pond, White Moun- 

 tain, and Lamoille scythestones. These schists are variable in 

 their structure, so that only portions or bands of them can 

 be utilized. The cutting quality of the stone varies with the 

 compactness of the schists and the percentage of quartz or 

 grit contained. There are two principal grades of stone found 

 at the New Hampshire quarries, which are known as the Indian 

 Pond and the White Mountain. Both of these stones come 

 from the same quarry. 



At Lisbon, Grafton county, N. H., there occurs a fine 

 grained quartz-mica-schist of a bluish chocolate color, which 

 furnishes a stone known as the chocolate whetstone. It is a 

 medium hard stone and is especially adapted for leather and 

 skinning knives, and it is also used extensively for sharpening 

 cloth cutters' tools, kitchen and carving knives, etc. 



The American buhrstone and millstone varies from a sand- 

 stone to a quartz conglomerate, which occurs along the east- 

 ern slope of the Appalachian mountains, from North Carolina 

 to New York, and is known by different names, according to 

 the locality from which it is obtained. Occasionally a granite 

 is also used in the manufacture of this stone. The states pro- 

 ducing buhrstones and millstones in 1902 were New York, 

 North Carolina, Pennsylvania, Vermont, and Virginia, by far 

 the larger production coming from New York. The buhrstone 

 produced in New York is principally from Ulster county, and 

 is known as Esopus stone. The Pennsylvania stones, which 

 are obtained in Lancaster county, are known as Turkey Hill 

 and Cocalico. From Montgomer}^ county, Va., is obtained a 

 buhrstone which is known on the market as Brush mountain
