"D'ye realise the dangers?"

"Dangers are nothing to me; I am used to them."

"But s'pose I should tell ye it's impossible to git behind the Golden
Crest?"

"Then, I like to do the impossible. There are plenty to do the
ordinary things. I want to do the extraordinary, the so-called
impossible. Did you ever hear the song that the Panama Canal diggers
used to sing to cheer them up?"

"No; what is it?"

"I only know four lines; they go this way:

"'Got any rivers they say are uncrossable?
Got any mountains you can't tunnel through?
We specialize on the wholly impossible,
Doing the things that no man can do.'

"I like those words, and they have heartened me more than once."

"They're sartinly stirrin', an' I like the spirit of 'em," the
prospector replied. "But it seems to me that ye've got to use common
sense as well as spirit. Now reason tells me that ye need someone to
help ye in this undertakin' of yours, an' why shouldn't that someone be
me?"
