Valley, the Moxahala Furnace at Moxahala, Fannie and XX Fur- 
naces at Shawnee, Helen and Lee Furnaces at Orbiston, and Mon- 
day and the new Floodwood Furnaces have been united under the 
management of the Standard Coal and Iron Company, of Columbus, 
Samuel Thomas, President. 
At Logan, Hocking county, is a charcoal furnace of an annual 
capacity of about 2,000 tons, which is geographically included in this 
district, though more properly associated with the Hanging Rock char- 
coal furnaces in condition of ores and fuel. 
The coals of the Hocking Valley will be fully discussed in the 
report on coal by the Chief Geologist, Prof. Edward Orton, but for con- 
venience of reference the following analyses of the principal furnace 
coals, made of samples taken for the Survey, and carefully averaged, 
are given here:

1. Coal from Akron Furnace, Buchtel, Hocking county. 
2. Coal from Suydam’s mines, Monday Creek. 
3. Coal from Doe’s mine. 
The details of the smelting and the different works will be dis- 
cussed in the part of this report relating to the metallurgy of the State. 
The Lake Superior ores used in the Hocking Valley district repre- 
sent most of the well-known mines. They are purchased in lots of various 
amounts by furnace companies from time to time—at present none of 
the companies own properties in the Lake region, though there is every 
probability that some of the large consolidations recently made of the 
firms in this district may, in order to be more dependent of market 
variations, arrange to purchase and develop mines in the Lake Superior 
and Canada iron fields. Canada ore of fine quality has been brought
