per cent, of iron in the furnace after it is calcined. Mr. Chamberlain 

 also reports that in some places over the stratified or black-band portion 

 of the Whitlock ore are considerable masses of nodular ore. Thus we 

 have in the same horizon black-band, massive limonite, and nodular ore. 

 As Mr. Chamberlain well says, the nodular ore may, in many places, 

 serve to indicate the horizon, and further =earch may reveal the black- 

 band itstlf. 



In the neighborhood of Bristol, in the same county, much larger areas 

 of the Iron Point ore have been found. These s.reas, already proven, 

 would make an aggregate of from one hundred and fifty to two hundred 

 acres, in which the ore is belisved to range from two to thirteen feet in 

 thickness. The ore under impervious cover will doubtless prove to be a 

 typical black band, with more than ten percent, of carbDuaoeous matter. 

 Through the courtesy of Mr. Chamberlain, of the Moxahala Iron Com- 

 pany, I have received the following analysis, by Mr. Gregory, of this 

 newly found ore. The sample analyzed was composed of borings ob- 

 tained in sinking holes to test the deposit.

It should be stated that Mr. Chamberlain estimates the stratigraphical 

 position of this ore to be from twenty to twenty five feet above the 

 Bayley's Run seam of coal, which, he says, is well developed in the neigh- 

 borhood of the ore. It is believed that this will prove to be a most val- 

 uable deposit of ore. 



On lower Sunday Creek large bodies of ore are found above the Bay- 

 ley's Run seam of coal. The ores are, generally, nodular on the outcrop, 

 but further exploration might bring to light localities where they form 

 regular layers. The largest deposits, so far as I have seen, are found in 

 a horizon ranging from ten to twenty-five feet above the seam of coal 

 referred to. The ore is, in plac^, very abundant, and could be advanta- 

 geously mined. At no point have I seen these ores assuming the charac- 

 ter of black band. The following analyses were made by Prof Wormley 

 of samples taken by myself, from different localities:
