"Kurho speaks big," sneered a young one, new in Council. "We have heard it before, always it is Kurho's tribe who is greatest in every deed...." He spat in contempt. * * * Days were gone, endless days without incident. But the reports came in--a mere trickle at first, and then in great tide. Kurho's tribe had indeed devised. Their weapon had been observed! Dak returned one day in high excitement, stumbling across the ledge from a long day's journey. "Kurho has devised better! We bring Obe the Bear, but they have now slain the great-toothed one. I saw it, I swear! They slew him easily!" He gasped for breath, then gained his feet and gave them eloquent gesture of what he had seen. There could be no doubt. Kurho now had a weapon much more facile, more deadly. Otah accepted grimly. Now it was he who must prove! He went to work at once, he and Gral, devising a weapon to meet the threat--more sharp-edged and deadly, of greater length and balance. It took days. And days more to seek out the place of the great-toothed ones. Not one but _three_ were slain, and it was made certain the word reached Kurho. But now Otah knew. He knew and was helpless. A frightful thing had been launched and there could be no turning; nothing now but the constant fear, the trap without end, the perilous thing above all their heads ... and the waiting. Kurho also waited. True, one thing remained to temper the distrust: sporadic communication had been established, a thing new and yet heavy with pretense, which again like a serpent at its tail spelled mutual distrust. But it was there, begrudging, and all the smaller tribes knew of it too--those scattered ones who were little more than clans. All the peoples of the valley watched and waited, aware of this thing between the two great tribes of Kurho and Otah. "It is better that we should talk, even endlessly, than to use such weapons tribe against tribe!" Such was Otah's word to those who grumbled and those who feared, and there was much to indicate that such was Kurho's feeling too. Indeed it appeared to be so! For the first time, Kurho relaxed his borders at Far End. Occasionally the Otah tribesmen were permitted to enter, welcomed without suspicion--a thing unprecedented! Similarly, select members from the Kurho tribe were accepted beyond the river; they displayed certain prowesses new to the Otah tribe, for in many ways these were a strange and fantastic people. It seemed to be a beginning. Word went out in secret and still other word returned, in which Mai-ak played a great part. And so, after scores of days it was done: there would be a time of understanding; Kurho, himself, would cross the river to go in person among Otah's people! When this was done, Otah would also cross the river to observe the things at Far End!
