Grandpa teetered forward and put out his hand. “Shake on that, boy!” he cackled. “Pop Truman ain't too old to have his little joke—and make it bring him in something, by Christmas! You saddle up and we'll go try him out on a quarter-mile—mebby a half, if he holds up good.”

He poked a cigarette-stained forefinger against Bud's chest and whispered slyly: “My son Dave, he 's got a horse in the stable that's been cleanin' everything in the valley. I'll slip him out and up the creektrail to the track, and you run that horse of yourn agin him. Dave, he can't git a race outa nobody around here, no more, so he won't run next Sunday. We'll jest see how yore horse runs alongside Boise. I kin tell purty well how you kin run agin the rest—Pop, he ain't s' thick-headed they kin fool him much. What say we try it?”

Bud stood back and looked him over. “You shook hands with me on it,” he said gravely. “Where I came from, that holds a man like taking oath on a Bible in court. I'm a stranger here, but I'm going to expect the same standard of honor, grandpa. You can back out now, and I'll run Smoky without any tryout, and you can take your chance. I couldn't expect you to stand by a stranger against your own folks—”

“Sho! Shucks a'mighty!” Grandpa spat and wagged his head furiously. “My own forks'd beat me in a horse race if they could, and I wouldn't hold it agin 'em! Runnin' horses is like playin' poker. Every feller fer himself an' mercy to-ward none! I knowed what it meant when I shook with yuh, young feller, and I hold ye to it. I hold ye to it! You lay low if I tell ye to lay low, and we'll make us a few dollars, mebby. C'm on and git that horse outa here b'fore somebuddy comes. It's mail day.”

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.
