and adjourned to Monday. During the session
important business was transacted. A pamph-
let Prospectus of the Co. . interests, cxpecta
tons, de-, &C., was ordered published. A sur
sey was reported from Secretary Beckwith.-
Agents we're appointed to procure an engine,
procure timber for derricks, &c, &c. The
Stock Books Of the Co. were received and
approved. Capt. z. II. Sherwin is the first
takcr Of stock on record. The enterprise is no
sham. The oil is there, and labor will soon
bring it to the surface in paying quantities.
For public satisfaction we give below the
report Of Doctor GASo. Of Chicago. This
gentleman was employed by the Company to
look tho grounds over and report its true
value, judging from what he could see. The
Go. wished to assure themselves. by scientific
exploration, before spending money that might
be lost in useless experiment. DR.. GASo is q
gentleman Of high standing as a geolosist, and
is usually advised with by parties in Chicago
who require investigations of this character -
We invite careful! perusal Of the Report

The mineral resources Of this portion of the
State are undcveloped, except by the upheaval
and extensive displacements of the rocks caus.

liarities Of the topography are due to the nature
OF the underlying strata. or to the operation of
subsequent agencies, the influence of which are
clearly traceable in all geological investigations
upon the surface. The main dividing ridge
between the Wisconsin and Miss. Rivers, ex.
tends up through Crawford Co., and along tho
apex Of this range, in the vicinity Of Copper
Greek, are found some very rich ores Of Iron
aAd Copper; there are also extensive faults.

thus forming conduits through which the water

rise Of metalliferous vapors and escaping of
the gases that are generated by the chemical
changes ever going on in the great laboratory
OF nature. Many faults occur in the first
stratum Of magnetism limestone in this district,
which form deep gorges or rayines; these show
the geological formation, distinctly, exposing
