(Abstract.) 



During March, 1887, Col. T. B. Sublet, United States 

 engineer, formerly of Frankfort, Ky., and Mr. W. B. Lenoir, 

 visited the farm of Elihu Humber at Powder Mill Creek, about 

 eight miles west of Rockwood Furnace on tbe eastern slope of 

 Crab Orchard Mt., latitude 35° 50' north, longitude 84° 45' 

 west of Greenwich, in Cumberland Co., Tennessee (Rockwood 

 being in Roan Co.). Mr. Humber showed them what he be- 

 lieved to be a piece of iron ore, and the two gentlemen decided 

 to divide the mass. Col. Sublet took off over 2,000 grams, 

 which were sent to me through the kindness of Mr. Moritz 

 Fischer, of the Kentucky Geological Survey, who suspected its 

 meteoric origin, and intended to forward the whole mass sub- 

 sequently. I was informed that the weight of the mass was 

 about 100 lbs., and that it measured 15 X 10 X 9 inches. It 

 belongs to the syssideres group or lithosiderites and polysideres, 

 of Daubree, and logronites, of Stan. Meunier. It also resem- 

 bles very closely the Hainholz, Westphalia, 1856, ^ and also the 

 Newton Co., Arkansas iron,' now the Taney Co., Missouri. 

 It is scarcely distinguishable from the latter by the eye, though 

 in the latter the grains are larger and more readily defined. 



The specific gravity of a piece was found to be 4.745. 



On action with nitric acid, this iron develops Widmanstatten* 

 figures very similar to those of the Estherville, lo., iron. 



Mr. J. Edward Whitfield, of the Geological Survey, had 

 made a very full analysis of the iron, consequently another was 

 not deemed necessary. 



Chloride of iron (laurencite) is present in considerable quan- 

 tities, and on a number of sections which had been cut and
