MINING AFFAIRS IN ARKANSAS. 
The traveling correspondent of the New York A@ining Record has been in- 
vestigating mining affairs in Pima county, Arkansas, and arrived at the conclu- 
sion that mines there are well worth owning, both gold and silver being found in 
goodly quantity. Writing from Dos Cabesas, he says: I went on top of the main 
mountain that I believe is as full of gold as a mountain can well be, and it was 
no fool of a job. It was a mountain ‘‘as is a mountain,” so steep that I left my 
mule at various points, and when I did attempt to ride him the same was of short 
duration, and it was harder to lead him than it was to do the walking. Prior to 
my ascension, I visited the Greenhorn, depth ten feet, with $70 gold assay ; 
Bear Core, depth seventy feet, silver, $90 per ton; Ewell Springs, sixty feet, 
average, silver, $30 per ton; Jumper, eighty feet, silver, with remarkable assays. 
On the top of this mountain, I found lead after lead pointing to and reaching the 
top; they are well defined and wide. Blind Tom could almost see them. Float 
matter could be picked up almost anywhere near the summit. By my guide I 
was told to select a piece, and he would ‘‘horn spoon” it for me. I did, and did 
my level best to make the worst selection I possibly could; I took a piece of 
tock that looked bad in every particular; in fact, the average man would not 
think it worth while to turn it over anywhere in a gold region, but when it was 
crushed and ‘‘horned” out, I saw a different feature in the case. By applying 
an eye-glass to the same, I found gold staring me in the face beyond the ques- 
tion of a doubt. I look upon this mountain as one containing wealth in gold al- 
most beyond computation. I do not give the opinion as an expert, but as one 
who has a pair of eyes in his head and sees in an unprejudiced manner. On 
both sides of the mountain, silver leads are thick and miners with plenty of ‘‘sand 
in their craw ” are hard at work developing the same. On the other side of the 
mountain, and nearer to Tombstone, other miners are at work developing the 
many leads they have discovered. —St. Louzs Journal of Commerce. 
PIPE-ORE LIMONITES. 
We can not pass without notice, the beautiful hypothesis offered by Professor 
Lesley (p. 17, QQ, Second Geological Survey of Pennsylvania) to explain the 
genesis of the ‘‘pipe-ore limonites.”” These are not to be confounded with the 
“‘pipe-veins”’ of Derbyshire, for instance, which are merely tubular bodies of 
lead ore occurring in fissure-veins. The ‘-pipes” of limonite are ‘‘ singular 
steeples of botryoidal and radiated iron ore,” which ‘‘rise from the solid ore at 
‘the bottom of some of our great mines to heights of fifty and even 100 feet, 
through deposits of ore-bearing clays which fill vast pots in the limestone coun- 
ery.”’ 
Professor Lesley says he has long held that these deposits are made in cav- 
erns, the roofs of which were subsequently carried away by erosion. But there
