Coal Measures. The peculiarity of the ore is the large percantage of 
lime carbonate disseminated through it. Thus brought into immediate 
contact with the particles of silica, the lime will serve an almirable 
purpose for flux, and the ore will scarcely require any added lime in the 
furnace. The ore is a very peculiar one, and a little special practice 
with it may be needed to show the best manner of treatment in a fur- 
nace. This ore corresponds much more nearly to the famous Minette 
ores of the odlite in the Grand Duchy of Luxemburg, of which more than 
a million of tons is annually mined, than any American ore I have seen. 
The Minette ores generally contain more alumina and also more phos- 
phorus. The average iron is thirty-three per cent. The ore often car- 
ries enough lime to serve as a flux without any foreign admixtures. The 
ore extends beyond the borders of Luxemburg, and is the basis of a large 
iron industry in neighboring kingdoms. More than one-third of the 
total production of pig iron in Belgium is made from these calcareo-sili- 
cious ores. Generally a ferruginous limestone is used for flux. ‘In the 
neighborhood of Longwyy, the predominance of silica and alumina is so 
noticable that the richness of the mixtures of ores decreases often to 
twenty-five per cent., by the addition of sterile lime, notwithstanding 
which the blast furnaces are, of all the French blast furnaces, perhaps 
those which work the most economically.” (Report of M. A. Habet, 
Liége.) 
On lower Sunday Creek, in Trimble township, an ore found a little 
below the Bayley’s Run coal has been reported. The ore is nodular, but 
the nodules are often large. Further explorations may reveal its ex- 
istence in a solid layer. A sample was analyzed by Prof. Wormley.
