Whitey learned afterwards this was a sort of pocket caused by the dripping of water, and containing a small but very rich quantity of ore.

Whitey also heard something about a certain date, on which the three were to be at a certain place, but here, to his disgust, the voices were again lowered, as if in caution.
On the whole, though this secret meeting seemed suspicious, the boy did not learn enough to form a basis for action.

Presently the men went away, and after waiting until he considered it safe, Whitey left the bunk house, followed by the faithful Bull.

Whitey decided not to tell Bill Jordan what he had heard.

Bill probably would only poke fun at him and hand him one of those arguments he couldn't answer.
But the next day he took Injun into his confidence.
