SUPPLEMENTAL REPORT—HOCKING VALLEY. 865 
Frank Baird, the superintendent, informs me that he has the “‘ Baird ore” 
and also the “ Bessemer ore.” At the time of my late visit the ores were 
not opened sufficiently for inspection. At Bessemer, and on Snow Fork, 
the Baird ore, if it exists, is below drainage, but Mr. Buchtel, of the 
Akron Furnace, proposes to search for it. Mr. W. B. Brooks has shown 
me samples of the Baird ore from his lands north of Nelsonville, and 
states that it is to be found there in its proper place below the Nelson- 
ville coal. I have seen the same ore on the Hayden lands, east of Hay- 
denville. It is here thirty-five feet below the Nelsonville coal, and at 
the bottom of the clay under Coal No. 5. It is ten inches thick and has 
the appearance of the Baird ore of the best type. Mr. Hayden has 
kindly given me an analysis made by Prof. Wormley :

No limestone has been seen under this ore. 
It will be observed that much of the iron in this ore is in the form of 
a carbonate of iron. This feature of the ore I have noticed at other 
localities. The ore commonly shows an odlitic structure, the grains of 
ore being embedded in a silicious matrix. These grains, originally a 
carbonate of iron, are not very readily oxydized. In some cases there 
is a similar odlitic structure of the ‘‘limestone ore” of the Hanging 
Rock Iron District, and the grains are found by analysis to be largely 
carbonate of iron. Two samples, one from the Vesuvius Furnace and 
the other from the Buckcye Furnace, gave respectively 4091 per cent. 
and 48.44 per cent. of carbonate, with 24.37 and 23.36 per cent. of ses- 
quioxide. Each was high in silica, the former containing 26.32 and the 
latter 23.36 per cent. The percentage of iron was low, being 36.81 and 
32.09, while the average per cent. of hydrated sesquioxides or limonites 
of the “‘limestone ore seam” of the Hanging Rock region is 51.67. The 
average silica in these limonites is 8.08 per cent., but if we except three
