landmarks."

The praise of Custer was sweeter to the young scout than that of any
other officer on the plains would have been.

At just four o'clock the mouse-colored mule jogged into Fort Larned and
waved a triumphant pair of ears. A short distance behind rode Custer, on
a thoroughly tired thoroughbred, while the escort was strung along the
trail for a mile back.

"Cody," laughed the general, "that remarkable quadruped of yours looks
equal to a return trip. Our horses are pretty well fagged out, but we
have made a quick trip and a good one. You brought us 'cross country
straight as the crow flies, and that's the sort of service I appreciate.
Any time you're in need of work, report to me. I'll see that you're kept
busy."

It was Custer's intention to remain at Fort Larned for some time, and
Will, knowing that he was needed at Hayes, tarried only for supper and a
short rest before starting back.

When night fell, he proceeded warily. On the way out he had directed
Custer's attention to signs denoting the near-by presence of a small
band of mounted Indians.

Suddenly a distant light flashed into view, but before he could check
his mule it had vanished. He rode back a few paces, and the light
reappeared. Evidently it was visible through some narrow space, and the
matter called for investigation. Will dismounted, hitched his mule, and
went forward.
