140 COKXJNDUM^ ITS OCCURBENCE AND DTSTRTBUTTON . 
adapted for use in the manufacture of the vitrified wheel. With the 
completion of the railroad to Franklin, which follows down the val- 
ley of the Little Tennessee River, from the (leorgia line, all of these 
deposits Avill be in close ]>roximity to railroad transportation. 
Six miles north of Burnsville, Yancey County, on the south side of 
Mine Fork, half a mile above its mouth and 300 feet al)ove it, corun- 
dum has been found Avhich is in very finely divided particles, inti- 
mately mixed with magnetite, menaccanite, and staurolite. The 
staurolite is transparent and of a rich brownish color, and has been 
mistaken for corundum. The staurolite and corundum together 
constitute from 5 to 10 per cent of these mixed minerals. The oidy 
work that has been done here is the sinking of two small openings, 
75 feet apart, on the strike (N. 25° E.) of the ore, which has exposed 
it for a width of G to 10 feet. Nearer the sunnnit of the ridge, and to 
the west, a similar outcrop of ore has been found. Unless it is found 
by further work that the percentage of the corundum increases, this 
deposit will liaA e little or no commercial value. The railroad is now 
within 3 miles of this deposit, and will give good transportation 
facilities if a large deposit of commercial ore sliould be developed. 
VIRGINIA. 
In Pittsylvania County, about If mih^s nearly due west of Whittles, 
a station on the Southern Kaih'oad, emei-y has l)een found at a num- 
l)er of localities on the lands of Messrs. Kicliard C. Keatts, J. I). 
Craddock, J. H. Hargeaves, and J. W. Xance, jind on the John 
Yeates estate. Surface emery is (juite abundant on many of these 
farms. The oidy ])lace Avhere any attempt has been made to explore 
the emery is on the Keatts farm, where two o])enings, al)out 300 feet 
apart, have been made, on what are apparently i)arallel Ai>ins. P]ach 
opening is al)out 20 feet deej). From the lower one two drifts, 10 to 
15 feet long, followed on the vein. All the rocks are saprolitic, but 
those inclosing the emery have the appearance of altered amphibo- 
lites or pyroxenites, and the occurrence is similar to that near Frank- 
lin, Macon County, N. C. 
The emery occurs in seams and loose fragments, Avhich are badly 
stained, but on a fresh fr-acture it is black and has a metallic- luster. 
CORUNDUM LOCALITIES IN THE UNITED STATES. 
Under this head are included j^ractically idl the* localities in the 
United States at which corundum has been found. If the localities 
liave already been described in the foregoing pages, they are simply 
mentioned here. OtherAvise, in most cases, the mode of occurrence 
and also some ideji of the extent and character of the corinuhnu are 
giA^en.
