A beggar with a silver mine is a pitiable pauper indeed if he cannot sell.
I spoke of the underground Virginia as a city.

The Gould and Curry is only one single mine under there, among a great many others; yet the Gould and Curry's streets of dismal drifts and tunnels were five miles in extent, altogether, and its population five hundred miners.

Taken as a whole, the underground city had some thirty miles of streets and a population of five or six thousand.

In this present day some of those populations are at work from twelve to sixteen hundred feet under Virginia and Gold Hill, and the signal-bells that tell them what the superintendent above ground desires them to do are struck by telegraph as we strike a fire alarm.

Sometimes men fall down a shaft, there, a thousand feet deep.
