He waved Bud toward his saddle and took himself off in a shuffling kind of trot. By the time Bud had saddled Smoky grandpa hailed him cautiously from the brush-fringe beyond the corral. He motioned toward a small gate and Bud led Smoky that way, closing the gate after him. The old man was mounted on a clean-built bay whose coat shone with little glints of gold in the dark red. With one sweeping look Bud observed the points that told of speed, and his eyes went inquiringly to meet the sharp blue ones, that sparkled under the tufted white eyebrows of grandpa. “Do you expect Smoky to show up the same day that horse arrives?” he inquired mildly. “Pop, you'll have to prove to me that he won't run Sunday--” Pop snorted. “Seems to me like you do know a speedy horse when you see one, young feller. Beats me't you been overlookin' what you got under yore saddle right now. Boise, he's the best runnin' horse in the valley--and that's why he won't run next Sunday, ner no other Sunday till somebuddy brings in a strange horse to put agin him. Dave, he won't crowd ye fur a race, boy. You kin refuse to run yore horse agin him, like the rest has done. I'll jest lope along t'day and see what yours kin do.” “Well, all right, then.” Bud waited for the old man to ride ahead down the obscure trail that wound through the brush for half a mile or so before they emerged into the rough border of the creek bed. Pop reined in close and explained garrulously to Bud how this particular stream disappeared into the ground two miles above Little Lost, leaving the wide, level river bottom bone dry. Pop was cautious. He rode up to a rise of ground and scanned the country suspiciously before he led the way into the creek bed. Even then he kept close under the bank until they had passed two of the quarter-mile posts that had been planted in the hard sand. Evidently he had been doing a good deal of thinking during the ride; certainly he had watched Smoky. When he stopped under the bank opposite the half-mile post he dismounted more spryly than one would have expected. His eyes were bright, his voice sharp. Pop was forgetting his age. “I guess I'll ride yore horse m'self,” he announced, and they exchanged horses under the shelter of the bank. “You kin take an' ride Boise-an' I want you should beat me if you kin.” He looked at Bud appraisingly. “I'll bet a dollar,” he cried suddenly, “that I kin outrun ye, young feller! An' you got the fastest horse in Burroback Valley and I don't know what I got under me. I'm seventy years old come September--when I'm afoot. Are ye afraid to bet?” “I'm scared a dollar's worth that I'll never see you again to-day unless I ride back to find you,” Bud grinned. “Any time you lose ole Pop Truman--shucks almighty! Come on, then--I'll show ye the way to the quarter-post!” “I'm right with you, Pop. You say so, and I'm gone!”
