"All right," said Bruce promptly, noting the while how the roving black eyes searched the edge of the ravine. "Stay here. Don't come nearer. You got buffalo meat?"

A grunt was the reply of one, a guttural "Buffalo, yes," the answer of the other.

"Bring tongues, then," and Bruce touched his own. "Five," and he threw forward the outspread right hand, rapidly touching in succession the thumb and four fingers. "We give both hands full—coffee, sugar, hardtack," and Bruce illustrated as he spoke. "That's all!" he finished abruptly, with the well-known Indian sign that plainly tells "I have spoken—there is nothing more to say," then calmly turned his back and, bidding Conroy follow, started to return to his comrades at the ravine.

But Indian diplomacy was unsatisfied. The Sioux had found "Big Nose" to be one of the soldiers in the field. He, at least, was of the hated troop that fought and chased Burning Star and killed Chaska. The trail told them there were nearly a dozen in the party, all on shod horses, with two in lead-spare mounts or pack-horses, doubtless—so they had extra rations and had come far; but why were they going this way, so far west of the usual road to the Big Horn posts? Why were they so few in number? Where were the rest? Why were they hiding here in the ravine, instead of marching? Answer to this last question was easy enough. It was to keep out of sight of Indian eyes and needed no excuse. There was something behind this mysterious presence of ten or twelve soldiers in the southern foothills, and Machpealota would expect of his scouts full information, hence the instant movement on the part of one of the two braves to follow.

Impressively, Bruce turned again and waved him back. "Go, get buffalo tongue," said he, "or no trade. Keep away from our tepees," and he drew with his spurred boot-heel a jagged line across the turf. "Your side," said he, indicating the slope to the southeast of the line. "This—ours. That's all!" And this time the Indian knew he must come no nearer.

"I've got 'em talking trade, lieutenant," reported Bruce, the instant he reached Dean's side. "We don't need the tongues, but we've got more coffee and sugar than we are apt to want, and at least we can keep them interested until dark, then we can slip away. Of course, they've sent word to their main body that we're over here, but I believe they can't come in force before night."

"They knew you, sergeant, and they know it is probably our troop," said he. "There must be only a small party near us. Make your trade, but while you're doing it we'll saddle. I mean to get out of this and into the thick of the timber before they can surround us. Stand 'em off, now, while we get ready."

Promises must be kept when made to an Indian, even if they are otherwise sometimes broken. In ten minutes, with coffee, sugar and hardtack in their hands, the sergeant and his comrades were back at the front. One brave was still there, the other had vanished. Five minutes, neither party saying a word, the troopers waited; then Bruce turned to Conroy. "I knew they had nothing to trade. Take this sack with you and fall back. Tell our fellows to keep me well covered till I follow." The instant the soldier started with the sack swung over his shoulder, the Indian, who had been squatted on the turf, sprang up and began rapid expostulation in fluent Ogallalla. "It's no use, young man," interposed Bruce. "Your chum there has no buffalo tongues, and he knew it. Here's some hardtack for you," and he spread one liberally with sugar and handed it to the ever-receptive paw, outstretched to grasp it. A glance over the shoulder showed that Conroy was nearly at the edge. Then, quietly, Bruce, too, began to retire. He had not got ten paces, still facing his unwelcome visitor, when the Indian gave a shrill, sudden cry and tossed up his hands. Not a second too soon Bruce turned and darted for cover. The Indian flung himself flat on the turf and rolled away into a depression where he could find partial shelter from bullets from the ravine, whence he evidently looked for them, and out from behind the knoll, bridles held high, "quirts" lashing at their ponies' flanks, darted half a dozen painted savages, tearing down upon the spot at the top speed of their agile mounts. Only two men remained on watch at the moment, Dean and one trooper. Most of the others, already in saddle, were filing away up the game trail that threaded the windings of the ravine, the two lead horses with them, while a few yards behind the young officer and his comrade, halfway down the reverse slope, two others, afoot, handled the reins of their own horses and those of the lieutenant and men still held at the edge. It was an exciting moment. Bruce had only a hundred yards to run before he could get under cover, and there was no chance of their hitting him at that range, yet a puff of smoke rose from the knoll, and a bullet, nearly spent, came tumbling and singing up the turf, and the dashing warriors, yelling wildly, applauded the shot. Bruce took matters coolly. Leaping behind the shelter of the ledge, he reached for his carbine, and in a moment more, as the pursuing Indians came lashing within long range, four seasoned cavalry carbines, each with a keen eye at the sight and a steady finger at the trip, were leveled on the coming foe. Dean's young heart beat hard, it must be owned, for hitherto the Indians had been fighting in retreat or on the defensive, while now they came as though confident of success; but there was soldier exultation and something like savage joy mingling with the thrill of excitement.

"There's more behind those beggars, sir," growled Conroy, a veteran at Indian work, "but they'll sheer off when they get within three hundred yards." On they came, shields and lances dangling, ponies on the keen jump, feathers and pennons streaming on the wind. But, just as Conroy said, no sooner was Bruce safely under cover and they felt themselves drawing within dangerous range than, fan-like, they opened out to right and left, and, yelling still like fiends, veered in wide circle from their line of attack, and ducking over their ponies' shoulders, clinging with one leg to the upright part of the cantle, they seemed to invite the fire of their white foe—and got it. A daring fellow in the lead came streaking slantwise across the front, as though aiming to pick up the comrade lurking in the dip of the prairie-like slope, and Conroy's carbine was the first to bark, followed almost instantly by Dean's. The scurrying pony threw up his wall-eyed head and lashed with his feathered tail, evidently hit, but not checked, for under the whip he rushed gamely on until another bullet, whistling within a foot of his neck, warned the red rider that he was far too close for safety, for with halting gait the pony turned and labored off the field, and presently was seen to be staggering. "Score one for our side," laughed the Irishman, in glee. "Now's your time, sergeant."

But Bruce, reloading, was gazing sternly at the distant knoll. The other warriors, riding right and left, were now chasing crosswise over the billowy slopes, keeping up a fire of taunt and chaff and shrill war-cries, but never again venturing within three hundred yards—never wasting a shot.
