What I saw on the west coast of South and North America, and at the Hawaiian Islands.: By H. Willis Baxley, M.D.

COAL.
connected by cross tunnels, and communicating with air-shafts
for ventilation. The perfect grade of the mine allows of an easy
removal of the coal by rail; more than a thousand tons have
already been sent to the San Francisco market, where it brings
twelve dollars per ton; and the farther the miners proceed, the
harder and richer is the coal. About three-quarters of a mile
beyond, the same vein has been opened at " Black Diamond"
mine, being four feet thick and somewhat harder than the Cumberland. No timbering is required at this mine, in consequence
of the sandstone rock formation which makes the tunnel selfsupportive. About a mile off, the "Adams," "Clark," and
"Cruikshank" mines are also furnishing coal of excellent quality; and it is expected that when a projected railroad is completed to the shipping point, aspiring to the metropolitan name
New York, five and a half miles distant, near the confluence of
the San Joaquin and Sacramento Rivers, coal will be delivered
in San Francisco at a greatly reduced price, in large quantity,
and of a quality equal to any imported into that market. A
thriving little village-Carbondale is being built near the
mines, which promises to rival in business activity, black dust,
black hands, black faces, black deeds, and black guards, its Atlantic namesake. It is situated one mile and a half northeast
of 3lonte Diablo-the sight of which alone repaid us for our
day's ride of thirty-two miles to the coal region and back to
Martinez, where we arrived in ample time for the call of the
evening Sacramento boat to San Francisco.
