At the moment he uttered an exclamation of impatience, he made out three figures of the natives, who advanced far enough from the wood for him to identify them.

Not only that, but they walked stealthily to the edge of the river and stood several minutes, as if looking across at the canoe.

Long was confident that he could drop one of them at least, and he was tempted to do so. The most effective way of keeping the savages off was by nipping their schemes in the bud, and filling them with additional terror of the white strangers.

But he decided to wait a while, suspecting, as he did, that some scheme whose nature he could not guess was under way, and that if the projectors were undisturbed, it would soon be revealed.

Jared Long, we say, was convinced that the natives were scrutinizing the canoe and seeking to learn something about the occupants, whom they had doubtless watched as they made their way from the water to the shelter of the wood. Such was his belief, and yet he was altogether mistaken.

It struck him as odd that the savages acted as they did, when it would seem that they could see just as well from the edge of the wood, where they were not exposed to the fire of their enemies; but he reflected that there was precious little about the conduct of the natives from the first that could be explained on the line of common sense and consistency.

The trio stood in view less than five minutes, when they darted back to cover, as if afraid of being seen by the whites, a theory altogether untenable under the circumstances.

The natural supposition of the sentinel was that a large number of the savages had gathered under the bank and were making ready for some demonstration, which would soon take place.

It was not yet time to awaken the Professor and the natives. In fact, the plucky New Englander half believed that with his repeating rifle he would be able to beat off any approach from the other shore.

At this moment, he was amazed to see one of the savages do an extraordinary thing.
