OF ARKANSAS. W41 
the lead contains 80 ounces of silver to the ton. The silver-lead of the 
Upper Hartz, belonging to Hanover, contains from 13 to 123 ounces of 
silver to the ton. From 70 to 80 ounces of silver is obtained from a ton 
of the argentiferous lead of Obernhof, in Saxony. 
From this it will be seen, that the silver-lead from the Kellogg mines 
greatly exceeds in richness the silver-lead ores of Europe, and in the com- 
parison, leaves a margin for profits so broad, that no doubt can be enter- 
tained of the practicability of working these ores, not only for the lead, 
but the silver. 
Why these mines have been so long abandoned, after having been once 
partially worked, I was unable to learn. The situation is highly favora- 
ble for rich lodes of metal, not only silver-lead, but also copper. 
If the property, belonging to these mines, can be obtained on reasonable 
terms, and a judicious and economical system of mining instituted, there 
can be but little doubt of a profitable result. The stratum of argillace- 
ous shale is easily mined, and there is no difficulty in sinking a shaft 
through it. From the increasing thickness of the shale to the south-east, 
it is difficult, at present, to state exactly, what the total thickness of the 
shales on Kellogg creek may be, before reaching the limestone; it may, 
probably, be 300 feet or upwards. 
The qualitative chemical examination of the Newton spring, on the 
property of John W. Purdom, in section 26, township 3 north, range 12 
west, 8 miles north of Little Rock, gave, as its principal constituents, 
Bi-carbonate of lime. 
Bi-carbonate of magnesia. 
Bi-carbonate of the protoxide of iron. 
This is a strong chalybeate water, and will be found an excellent tonic 
for patients suffering from debility. 
Two and a half miles east of Mr. Purdem’s, between the old Batesville 
and Memphis roads, there is a large body of bog-iron ore, which will, no 
doubt, be found to contain sufficient iron to pay for working, judging from 
its appearance. A strong chalybeate spring breaks out from this bed of 
ore. Several persons have been induced to sink prospect holes, for lead, 
in this vicinity; all of which reached bog-iron ore, proving this ferrugin- 
ous deposit to be extensive. Its thickness, where it was only partially 
exposed, is two feet. This is, therefore, a locality worthy of the attention 
of the iron manufacturer.
