Knowing that we had foes in the neighbourhood sentinels were posted, two of whom kept watch all the night round the camp; but the strangers, seeing us prepared, did not make their appearance, and on the following morning we started, an hour before dawn, on our return.  Kepenau kept in the rear, turning round very frequently to ascertain if we were followed.  He also gave his people directions to keep a look-out on either hand.  Once he caught sight of a warrior's plume in the distance, but although his eyes were of the sharpest he could not discover whether his foe approached nearer.  Before evening we arrived safely at his lodges; the ample supply of food we brought affording great satisfaction.  The chief, however, did not fail to send out scouts to bring word whether the enemy had ventured into the neighbourhood.  As no traces of them could be seen, Kepenau came to the conclusion that the strangers had gone off again to the westward, content with the game they had obtained.  Still, he thought it prudent, in case of treachery, to keep on the watch; and day and night two or three of the party were constantly scouring the country round, in search of tracks made by strange Indians.
