From his position, prone on the earth, the youth was able to follow him with his eyes for some distance. The sight was curious, as he dodged from tree to tree, his body bent over like a centenarian under the weight of his multitudinous years.

Nothing could have been done with more exquisite skill, and, when he too passed from sight, the one left behind knew that the Pawnees would steal no march upon them.

"Let me see," said he, his spirits rising as the situation improved, "I've got plenty of ammunition for my rifle, and besides that, here are Deerfoot's bow and arrows. If I had a fort, like that which sheltered Otto and me on the other side the Mississippi, I might stand a siege. There would be one good thing," he added, as he surveyed the aboriginal weapon; "when I fired this off, none of the Indians would know which one it was to hit—it certainly wouldn't be the one I aimed at, and I couldn't guess for myself."

Rising to his feet, he scrutinized every part of the wood, but there were no signs of the Pawnees, who, it was more than probable, had passed down the river shore and away from the vicinity.

"Now we have done a good deal of tramping back and forth," reflected the youth, "and those redskins are so sharp that the chances are ten to one they will come upon our footprints. It won't do to sit here all day until some of them tumble over me."

It was clear to Jack that the hostiles had started out on what was likely to be an extended reconnoissance, and, therefore, were sure to be gone a considerable while. As the canoe lay only a short distance off, he passed through the wood and undergrowth until he reached the spot where it was drawn only a few inches up the bank.

He surveyed it with natural curiosity, though he had seen many similar ones further to the east. It was about fifteen feet long, made of bark, sewed together, and the cracks filled with gum. The ends were curved over, so there was no difference between them, and each was ornamented with paintings which composed a symphony in black, red and yellow.

Two long paddles lay lengthwise in the boat. They were double—that is, the handle was in the middle, the ends being dipped alternately by whomsoever was propelling the craft. Jack looked behind him several times, before resting his hand on the gunwale. Something else which lay at the further end interested him, but he could not make it out at once. Leaning forward, he reached it with his bow, and then observed that it was a scalp. The barbarous trophy, by some unusual accident, had dropped unnoticed from the belt of one of the Pawnees, for it is not to be believed that he would have left such a prized souvenir behind him, no matter on what duty engaged.

The ragged patch of skin that had been torn from the crown of some vanquished foe was three or four inches in diameter, and the tuft of hair was long, black and coarse. Whoever had succumbed and borne the outrage, one thing was certain—he was not a Caucasian, but belonged to the same race as his conqueror.

Jack, who had seen such trophies many times, raked this one still closer and picked it up. The dryness of the skin showed that several weeks had passed since it was taken. More than likely it was the accompaniment of some fight that took place while the Pawnees were pushing their explorations toward the Mississippi.
