But the oldest of them left an infant son. The child's mother brought him up to avenge the killing of his kinsmen. So the son grew very strong, until he could pull up great fir trees as if they were weeds. Then Walla Walla brothers challenged Young Chinook to wrestle. Speelyei should judge the contest. He should cut off the heads of those who fell. Secretly Speelyei advised Young Chinook's grandparents to throw oil on the ground last. This they did. So Walla Walla brothers were thrown one after another by Young Chinook, until four of them had fallen. Only the youngest of them was left. His heart failed him, and he refused to wrestle. Speelyei pronounced this sentence upon him: "You shall live, but you shall no longer have power to freeze people." To Young Chinook, he said: "You must blow only lightly, and you must blow first upon the mountains, to warn people of your coming."

This name, meaning literally flat stones, was given by the early French-Canadian voyageurs to the twelve-mile section below Celilo, where, the Columbia has cut through the level lava strata, forming a channel in some places less than 200 feet wide and nearly 200 feet deep at low water. At higher stages the river fills many lateral channels and roars past many islands of its own carving.] The last dawn of all opens upon the white man's era. On the Columbia, recorded history is recent, but already epic. Its story is outside the purpose of this volume. But it is worth while, in closing our brief glance at the field, to note that this story has been true to its setting. Rich in heroism and romance, it is perhaps the most typical, as it is the latest, chapter in the development of the West. For this land of the river, its quarter-million square miles stretching far northward to Canada, and far eastward to the Yellowstone, built about with colossal mountains, laced with splendid waterways, jeweled with beautiful lakes, where upheaval and eruption, earthquake and glacier have prepared a home for a great and happy population, has already been the scene of a drama of curious political contradictions and remarkable popular achievement.
