200 REPORT OF STATE MINERALOGIST.

veined by magnesite, forming a stone of the 'verde antique' type, lie
undeveloped west of Drytown.

Amador Marble Quarry is 2\ miles east of Plymouth in the canyon
of a north fork of Dry Creek. The deposit was opened years ago about
100 feet wide and 100 feet high, but has been idle recently. It is a
gray and blue clouded stone. The quarry is about 13 miles from the
railroad station of Carbondale. Alessio Dalporto, Plymouth, owner.

Carrara Marble Quarry is about four miles by road northwest of

Pine Grove on the south side of the canyon of Sutter Creek, and 12
miles by road from Martell railroad station. A body of white marble,
irregularly veined and splotched with blue, has been stripped on the
canyon side for a width and height of about 150 feet. The quarry is
worked in the dry season by C. Dondero, who ships the stone for use
in San Francisco. Blocks of good size are taken out and shipped
in the rough state. There is a small derrick and engine for handling
the blocks.

Near Volcano and adjoining the Elephant hydraulic mine, James
Cosgrove, Jackson, has a 20-acre placer claim, and John Rossi of Sutter

Creek and other parties have 40 acres covering parts of the large area
of limestone and marble near the corner common to Sees. 14, 15, 22

and 23, T. 7 X., R. 12 B. Tin- stone is in places a white marble with
tree-like black veining. It forms the bedrock of tin old placer diggings
1
and in places the rim of the old channel, and has been deeply guttered
l>\- erosion. No work has been done here.

Wait MarbU Deposit is three miles west of Drytown and eight miles
by road from Carbondale railway station. A hard, durable marble,
having a beautiful cherry red color when polished, outcrops near Ihe

road over an area of 160 by 400 feet. The surface of the deposit is flat.
The only work done has been one drill hole which was pu1 down about

three y.-ai-s ago by California Slimes Company, under the direction of
\V. E. Harrow. This hole is -Hi feel deep, and is reported to show the
marble all the way and in the bottom.

Near the red marble there is ;i small outcrop of the 'verde antique'
type, serpentine veined by magnesite, on which nothing has been done.

MANGANESE.

During the war period between 1915 and 1911), several manganese
prospects were worked on a small scale in this county, and there was
some production. There is no record of activity in this line since 1919.
The following properties were mentioned in our Bulletin 76,
Manganese and Chromium in California:

Crocker-Preston property is in the SWJ of Sec. 35, T. 7 N., R. 12 E.,
M. D.M., a mile and a half south of Volcano, and is owned by M. I.

Crocker and J. W. Preston, Jr., 350 Post Street, San Francisco. It is
12 miles from Martel railroad station.
Lenses of manganese ore, some resembling deposits from mineral
springs, occur in a mineralized zone at least 100 feet wide on contact
between limestone and schist. Good grade ore was found, and some
of it was mined.
