Meanwhile, Big Jim tried to blind himself to his wife's growing
dissatisfaction. He was too much of a man to argue her own short-comings
as against his inability to do more for her than he was doing. But when
she did leave, with simply a brief note saying that she was tired of it
all, and would take care of herself, what hit Big Jim the hardest was
the fact that she could give up Little Jim without so much as a word

pack-animal. Little Jim, used to the saddle, would find the journey a
real adventure. They would take it easy. There was no reason for haste.

It had seemed the simplest thing to do, to sell out, leave that part of

Jim Hastings. Mrs. Hastings was still young and quite good-looking.

It had seemed a simple thing to do--to leave and begin life over again
in another land. But Big Jim had forgotten Smiler. Smiler was a dog of
