reputation of being a “strong” coal, well adapted to the generation of 
steam, but containing too much sulphur to be used in the manufacture 
of iron. In this region it varies from four to five feet in thickness. At 
Port Washington it lies about one hundred feet above the canal, is from 
five to seven feet thick, is very bright, black and handsome, but contains 
a great deal of sulphur. In the valley of Stone Creek this coal is thin 
and poor. On Oldtown Creek, however, it appears better, attaining a 
thickness of four to five feet, and furnishing coal of good quality. 
In the north-western part of the county, Coal No. 6 is opened in various 
places, and in the valley of Sugar Creek, about Dundee, is unusually 
good. . 
From the facts which I have given, it is apparent that within the 
limits of Tuscarawas county, Coal No. 6 represents a vast amount of 
mineral fuel. Asa general rule the coal it furnishes is rather soft, con- 
tains considerable sulphur, and is highly cementing in character. It is 
evident, therefore, that some method of treatment must be adopted that 
will convert this into a first-class fuel for manufacturing purposes. The 
importance of this problem cannot well be over-estimated. If by any 
cheap process of preparation this coal may be made to supply a pure fuel, 
it will be a source of great wealth to the county. It will, no doubt, sup- 
ply many of the purposes of a mineral fuel in its natural state—that is, 
it serves well for household use and for the generation of steam—but for 
the manufacture of iron it will be necessary to eliminate a considerable 
portion of the sulphur it contains before the best results will be attained 
in its use. It forms a strong adhesive coke, and one that has high heat- 
ing power, and is capable of bearing a heavy burden, yet if not purified, 
the sulphur it contains will, perhaps, preclude its use. Under these cir- 
cumstances, I cannot too strongly urge the adoption, in the southern por- 
tion of Tuscarawas county, of such methods of coal washing as are found 
to be effieacious in the treatment of similar coals. It is probable that 
simply by the imitation of methods that are now in use in our own coun- 
try, and one still more generally employed abroad, a good coke can be 
formed from No. 6 coal, and that when so treated this will furnish a fuel 
which will not only serve for the manufacture of all the iron ore found 
within this county, but will invite and bring to this source of fuel the 
iron ores of Lake Superior. 
Tuscarawas county already enjoys such facilities for transportation that 
her resources need no longer be considered as land-locked and left unde- 
veloped. By the great east and west route—the Pittsburgh, Cincinnati 
and St. Louis Railroad—which traverses the southern portion of the 
county, ready communication is afforded with Pittsburgh on the one
