There was a considerable break in the rocky barrier here, leading back for perhaps a hundred yards, and the plainsman turned his horse that way, dismounting when out of sight among the bowlders.

He could rest here until night with little danger of discovery.

He lay down on the rocks, pillowing his head on the saddle, but his brain was too active to permit sleeping.
Finally he drew the letters from out his pocket, and began examining them.

They yielded very little information, those taken from the older man having no envelopes to show to whom they had been addressed.

The single document found in the pocket of the other was a memorandum of account at the Pioneer Store at Topeka, charged to John Sibley, and marked paid.
