Roughing it, Part 3 by Mark Twain — Read

I met men at every turn who owned from one thousand to thirty thousand "feet" in undeveloped silver mines, every single foot of which they believed would shortly be worth from fifty to a thousand dollars -- and as often as any other way they were men who had not twenty-five dollars in the world. Every man you met had his new mine to boast of, and his "specimens" ready; and if the opportunity offered, he would infallibly back you into a corner and offer as a favor to you, not to him, to part with just a few feet in the "Golden Age," or the "Sarah Jane," or some other unknown stack of croppings, for money enough to get a "square meal" with, as the phrase went. And you were never to reveal that he had made you the offer at such a ruinous price, for it was only out of friendship for you that he was willing to make the sacrifice. Then he would fish a piece of rock out of his pocket, and after looking mysteriously around as if he feared he might be waylaid and robbed if caught with such wealth in his possession, he would dab the rock against his tongue, clap an eyeglass to it, and exclaim:

"Look at that! Right there in that red dirt! See it? See the specks of gold? And the streak of silver? That's from the Uncle Abe. There's a hundred thousand tons like that in sight! Right in sight, mind you! And when we get down on it and the ledge comes in solid, it will be the richest thing in the world! Look at the assay! I don't want you to believe me -- look at the assay!"
