No mines have as yet been opened in this county, but 
it affords plenty of iron ore, of the richest kind, It is usually 
of that sort denominated red, or brown ore, and is found in 
Jumps or nodules of various sizes, from that of the smallest 
shot up to pieces weighing 80 or 100 pounds. arth 
appears to be full of it in many places; and in others it is 
deposited in beds of considerable extent; pa as no one has 
as yet erected any works, it is not known how abundant the 
ore may be; but I have no doubt of its beibe’ in sufficient 
quantity to supply any Or that may be built. Someo 
it has been melted dov common blacksmith’s furnace, 
and worked into selene iron. Ores of any other metals 
lave not been discovered, in such circumstances as to make 
them an object of attention. Some small lumps of native 
bismuth were found in the bed of a run in this Reepueos 
hood, a few years since, but the vein from which they were 
washed has not been discovered, although repeatedly search- 
ed for. Isent some of it to Dr. Barton at iladelphia, who 
pronounced it to be of the purest kind. I have in my pos- 
session, a small ingot of metal which was obtained from ore 
found in the S. E. part of this county, which appears to me 
to be tin and zinc combined. I have not been able as yet to 
learn, whether it exists in quantities sufficient to make it an 
object of attention. Flint stone bas not been found in this 
county. Limestone is plenty. Sulphate of lime has been 
found in several places, but not in sufficient quantities to be 
nsed as‘an article of manure. The greatest collection that 
|. have heard of, was found in digging a well, between Duck 
creek and Little Maskingum creek, within the limits of 
Marietta Township. The stratum was about ten inches or a 
foot in thickness, and about twelve feet below the surface. 
How extensive it may be is not known ; as the workmen soon 
after came to water, and the well was stoned up without fur-
