Famous quotes containing the word mines:
“Beautiful credit! The foundation of modern society. Who shall say that this is not the golden age of mutual trust, of unlimited reliance upon human promises? That is a peculiar condition of society which enables a whole nation to instantly recognize point and meaning in the familiar newspaper anecdote, which puts into the mouth of a distinguished speculator in lands and mines this remark:M”I wasn’t worth a cent two years ago, and now I owe two millions of dollars.””
—Mark Twain [Samuel Langhorne Clemens] (1835–1910)
