And so they were led into the venture. They sought, too, the aid of the Shell People in this raid, but were not successful. The Shell People were not unfriendly to those of the Fire Valley, and had not Ab been really the one to kill the tiger? Besides, it was not wise for the waterside dwellers to engage in any controversy between the forest factions, for the hill people had memories and heavy axes. A few of the younger and more adventurous joined the force of Boarface, but the alliance had no tribal sanction. Still, the force of the swarthy leader of the Eastern cave men was by no means insignificant. It contained good fighting men, and, when runners had gone far and wide in the Eastern country, there were gathered nearly ten score of hunters who could throw the spear or wield the ax and who were not fearful of their lives. The band led by Boarface started for the Fire Country, intending to surprise the people in the valley. They moved swiftly, but not so swiftly as a fleet young man from the Shell People who preceded them. He was sent by the elders a day before the time fixed for the assault, and so Ab learned all about the intended raid. Then went forth runners from the valley; then the matron Lightfoot's eyes became fiery, since Ab was threatened; then old Hilltop looked carefully over his spears, and poised thoughtfully his great stone ax; then Moonface smote her children and gathered together certain weapons, and then Old Mok went into his cave and stayed there, working at none knew what.
