If there had been any doubt in the first instance that Indian Jake was guilty, and Eli had never admitted that there was doubt, he was now entirely satisfied of the half-breed's guilt.

"He's had a warnin' and he'll not bide in that camp another day.

He'll flee the country." Then Eli's thoughts turned to his old father and mother.
"The silver's gone, and it leaves Pop and Mother in a bad way," he mused.
