"Wa'al, I had my share on it, ain't I, Zeb?" said the old man to Zeb, who had just strolled up, smoking a short, black pipe. The professor, after adjusting his difficulties with the landlord, was sorting and labeling specimens in his room.

"Give me the fillin's, then, an' I will," said old Pete, holding out a blackened and empty corncob, "though I'm surprised they ain't never heard on it. Thought everybody had heard of Peg-leg's mine."

"Ah, that accounts fer it," said old Pete indulgently. "You couldn't 'spec Easterners ter know nuthin' 'bout it.

"Who was Peg-leg? Wa'al, that's in a way not very well known. Anyhow, his name was Smith, and he was shy an off leg, and so he gets his name. Back in 1836 Peg-leg he blows inter Yuma with a party of trappers that hed worked down ther Colorado.
