"If they have halted they would not sleep without a sentry," said Bob.
"That is true, I suppose," admitted the other, grudgingly. "All Indians are careful not to be taken by surprise. Yes, they would be on their guard; but what of that, Bob? Surely, with Blue Jacket to help us, we could creep up close without any one being the wiser."
"You forget," said Bob, "that we could never follow the trail without a light; and those sharp eyes of the sentry would discover our torch long before we knew they were near. Then we would be made a target for a shower of bullets, and perhaps poisoned arrows."
Sandy was utterly disheartened. This sort of argument seemed unanswerable. He just gave a disgusted grunt, rolled over on the ground, and not another word did he speak during the entire balance of that long night.
Bob knew that sleep had finally overtaken his brother, for he could hear his regular breathing after a time. And he was glad of the fact, for both, of them stood much in need of rest before they would be in condition to take up the chase once more.
Morning found them awake, and ready to make a fresh start just as soon as the daylight proved strong enough for the Indian to see the trail. Bob was only too willing to turn over the lead to Blue Jacket, knowing that, while he, himself, might serve fairly well, he was not at all in the same class as the trained young Shawanee, accustomed to reading every tiny sign that marked the tracks of the red fugitives.
Once again they chewed some of the dried venison, washing the crude meat down with a draught from a near-by brook. Refreshed after their sleep, the two boys declared themselves to be in good condition, and ready to make a day of it, if need be.
More than once Bob noticed that the Indian cast an apprehensive glance upward. Sandy, too, saw this action, and took the first opportunity to question his brother as to what it might signify.
"Why does he turn his eyes up to the tops of the trees every little while?" he said in an aside to his brother, as the two of them trailed after Blue Jacket.
