which is perfectly flat and from it there projects a tip or point. 

 Its specific gravity is 7'06. It is quite soft compared with 

 iron. Most of the surface is covered with a very thin coating 

 of rust. When polished and etched with dilute acid the Wid- 

 mannstatten lines appeared very distinctly and beautifullv. 

 Chemical analysis gave: Fe 91-36, Ni 7*56, Co 070, P 0-09, 

 S 0-06, Si, trace = 99 -77. 



[Nothing is known as to the time of its fall, though as it was 

 found covered by several feet of stones which have not moved 

 sensibly since the Susquehanna Valley has been inhabited by 

 white men it could not have been recent. As far as can be 

 learned this is the only specimen of the fall which has been 

 found.

1. Indian Valley Township, Floyd County, Virginia. 



In the spring of 1887 a mass of meteoric iron was turned up 

 hy Mr. John Showalter, while plowing his tobacco-patch, situ- 

 ated in Indian Valley Township, near the Carroll and Pulaski 

 lines, and near the base of the south side of Floyd Mountain, 

 six miles southeast of Radford Furnace, Virginia. He made 

 careful search in the near vicinity for other pieces, but with- 

 out success. This meteorite weighs thirty-one pounds, or four- 

 teen kilos. It measures 28x20x13 centimeters, or 11x8x5 

 inches. The surface of the iron is very much corroded and is 

 entirely covered with a limonite crust, very little of the orig- 

 inal crust being visible. On the exterior are deep depressions 

 from two to four centimeters in diameter. The iron is highly 

 crystalline, and a piece was readily removed from an old 

 fracture. When etched with hydrochloric acid it did not 

 show the Widmannstatten figures. 



The following analysis was made by Mr. L. G. Eakins, 

 through the courtesy of Professor F. W. Clarke, of Washing- 

 ton, chief chemist of the United States Geological Survey.
