legs fail you at last, you lie down in a small box-car in a cramped
"incline" like a half-up-ended sewer and are dragged up to daylight
feeling as if you are crawling through a coffin that has no end to it.
Arrived at the top, you find a busy crowd of men receiving the ascending
cars and tubs and dumping the ore from an elevation into long rows of
bins capable of holding half a dozen tons each; under the bins are rows
of wagons loading from chutes and trap-doors in the bins, and down the
long street is a procession of these wagons wending toward the silver
mills with their rich freight. It is all "done," now, and there you are.
You need never go down again, for you have seen it all. If you have
forgotten the process of reducing the ore in the mill and making the
silver bars, you can go back and find it again in my Esmeralda chapters
if so disposed.

Of course these mines cave in, in places, occasionally, and then it is
worth one's while to take the risk of descending into them and observing
the crushing power exerted by the pressing weight of a settling mountain.
I published such an experience in the Enterprise, once, and from it I
will take an extract:

AN HOUR IN THE CAVED MINES.--We journeyed down into the Ophir mine,
yesterday, to see the earthquake. We could not go down the deep
incline, because it still has a propensity to cave in places.
Therefore we traveled through the long tunnel which enters the hill
above the Ophir office, and then by means of a series of long
ladders, climbed away down from the first to the fourth gallery.
Traversing a drift, we came to the Spanish line, passed five sets of
timbers still uninjured, and found the earthquake. Here was as
complete a chaos as ever was seen--vast masses of earth and
splintered and broken timbers piled confusedly together, with
scarcely an aperture left large enough for a cat to creep through.
Rubbish was still falling at intervals from above, and one timber
which had braced others earlier in the day, was now crushed down out
of its former position, showing that the caving and settling of the
tremendous mass was still going on. We were in that portion of the
Ophir known as the "north mines." Returning to the surface, we
entered a tunnel leading into the Central, for the purpose of
getting into the main Ophir. Descending a long incline in this
