He picked up and shook in his hand the short lance, steel-tipped, which Weucha was carrying. The latter grinned and nodded his assent, handing the weapon to the red-haired leader.

“Now we shall serve!” said Lewis an instant later; for they brought out two handsome horses, one coal-black, the other piebald, both mettlesome and high-strung.

That the young men were riders they now proved, for they mounted alone, barebacked, and managed to control their mounts with nothing but the twisted hide rope about the lower jaw—the only bridle known among the tribes of the great plains.

The crier now passed down the village street, marshaling all the riders for the chase. Weucha gave the signal to advance, himself riding at the head of the cavalcade, with the two white captains at his side—a picture such as any painter might have envied.

Others of the expedition followed on as might be—Shannon, Gass, the two Fields boys, others of the better hunters of the Kentuckians. Even York, not to be denied, sneaked in at the rear. They all rode quietly at first, with no outcry, no sound save the steady tramp of the horses.

Their course was laid back into the prairie for a mile or two before a halt was called. Then the chief disposed his forces. The herd was supposed to be not far away, beyond a low rim of hills. On this side the men were ranged in line. A blanket waved from a point visible to all was to be the signal for the charge.

Dorion, also stripped to the waist, a kerchief bound about his head, carrying a short carbine against his thigh, now rode alongside.

“He say Weucha show you how Sioux can ride,” he interpreted.

“Tell him it is good, Dorion,” rejoined Lewis. “We will show him also that we can ride!”
