“Oh, come on,” Park cried impatiently. “We can't do any good sitting out here in the rain. I don't suppose the water will get clear up to the house; it'll likely do things to the sheds and corrals, though, and serve Jack right. Come on, Bud. Mona won't have us around, so the sooner we get under cover the better for us. She's got lots uh nerve; I guess she'll make out all right.” There was common sense in the argument, and Thurston recognized it and rode on to camp. But instead of unsaddling, as he would naturally have done, he tied Sunfish to the bed-wagon and threw his slicker over his back to protect him from the rain. And though Park said nothing, he followed Thurston's example. CHAPTER XIII. “I'll STAY--ALWAYS” For a long time Thurston lay with wide-open eyes staring up at nothing, listening to the rain and thinking. By and by the rain ceased and he could tell by the dim whiteness of the tent roof that the clouds must have been swept away from before the moon, then just past the full. He got up carefully so as not to disturb the others, and crept over two or three sleeping forms on his way to the opening, untied the flap and went out. The whole hilltop and the valley below were bathed in mellow radiance. He studied critically the wide sweep of the river. He might almost have thought it the Missouri itself, it stretched so far from bank to bank; indeed, it seemed to know no banks but the hills themselves. He turned toward where the light had shone among the cottonwoods below; there was nothing but a great blot of shade that told him nothing. A step sounded just behind. A hand, the hand of Park, rested upon his shoulder. “Looks kinda dubious, don't it, kid? Was yuh thinking about riding down there?” “Yes,” Thurston answered simply. “Are you coming?” “Sure,” Park assented. They got upon their horses and headed down the trail to the Stevens place. Thurston would have put Sunfish to a run, but Park checked him. “Go easy,” he admonished. “If there's swimming to be done and it's a cinch there will be, he's going to need all the wind he's got.” Down the hill they stopped at the edge of a raging torrent and strained their eyes to see what lay on the other side. While they looked, a light twinkled out from among the tree-tops. Thurston caught his breath sharply. “She's upstairs,” he said, and his voice sounded strained and unnatural. “It's just a loft where they store stuff.” He started to ride into the flood. “Come on back here, yuh chump!” Park roared. “Get off and loosen the cinch before yuh go in there, or yuh won't get far. Sunfish'll need room to breathe, once he gets to bucking that current. He's a good water horse, just give him his head and don't get rattled and interfere with him. And we've got to go up a ways before we start in.”
