Brodie went at it right. He tried, not to make friends with the Spider, for nobody could do that, but to get acquainted with it. For this he went to its oldest neighbors, the Sioux. Brodie spent weeks and weeks up the Spider Water hunting, summers; and with the Sioux he talked Spider Water and drank fire-water. That was Brodie's shame--the fire-water. But he was pawky, and he chinned unceasingly the braves and the medicine men about the uncommonly queer water that took the bridges so fast. The river that month in and month out couldn't squeeze up water enough to baptize a pollywog and then, of a sudden, and for a few days, would rage like the Missouri, restore to the desert its own and living image, and leave our bewildered rails hung up either side in the wind. Brodie talked cloudbursts up country; for the floods came, times, under clear skies--and the Sioux sulked in silence. He suggested an unsuspected inlet from some mountain stream which maybe, times, sent its storm water over a low divide into the Spider--and the red men shrugged their faces. As a last resort and in desperation he hinted at the devil; and the sceptics took a quick brace with as much as to say, now you _are_ talking; and muttered very bad Medicine. Then they gave him the Indian stuff about the Spider Water; took him away up where once a party of Pawnees had camped in the dust of the river bed to surprise the Sioux; and told Brodie how the Spider, more sudden than buck, fleeter than pony, had come down in the night and surprised the Pawnees--and so well that the next morning there wasn't enough material left for a scalp dance. They took Brodie out into the ratty bed himself and when he said, heap dry, and said, no water, they laughed, Indianwise, and pointed to the sand. Scooping little wells with their hands they showed him the rising and the filling; the instant water where before was no water. And dropping into the wells feathers of the grouse, they showed Brodie how the current carried them always across the well--every time, and always, Brodie noticed--southeast. Then Brodie made Hailey dig many holes, and the Spider welled into them, and he threw in bits of notebooks and tobacco wrappers, but always they travelled southeast--always the same; and a bigger fool than Brodie could see that the water was all there, only underground. But when did it rise? asked Brodie. When the Chinook spoke, said the Sioux. And why? persisted Brodie. Because the Spider woke, said the Sioux. And Brodie went out of the camp of the Sioux wondering. [Illustration: Hailey] And he planned a new bridge which should stand the Chinook and the Spider and the de'il himself, said Brodie, Medicine or no Medicine. And full seven year it lasted; then the fire-water spoke for the wicked Scotchman--and he himself went out into the night.
