He became a Montana dog.

The city was to know him no more.
Now he waddled along after Whitey, who was making for a straw stack, near the stable.

Among the field mice, gophers, rabbits, and such that thought this stack was a pretty nice place to hang around, were two hens that were of the same opinion.

At least they made their nests in the stack and laid their eggs there.

And they were the only hens that the Bar O boasted, for hens were scarce in Montana in those days--as Buck said, "almost as scarce as hen's teeth, an' every one knows there ain't no such thing." It was Whitey's particular business to gather the eggs of those hens, which they saw fit to lay early in the morning.
