Finally he found it necessary to stop now and then and examine the ground thoroughly.
"We shall not overtake them before dark, shall we?" asked Frank, anxiously.
"Hard tellin'. Watch out. May run onter 'em any time."
When they halted again, Frank suddenly uttered a low cry of warning, caught hold of the man, and exclaimed:
"Look there!"
Through the darkness they saw the twinkle of a camp-fire.
"Thet settles it!" breathed Old Rocks, exultantly. "The skunks are thar! We've run 'em down!"
He gave no further attention to the trail, but straightway made sure that every weapon he possessed was ready for use.
"Now, boy," he whispered, "keep yer nerve. Thar'll be need enough o' it afore long."
"I am with you," assured Frank. "I do not think I shall lose my nerves in this case."
"Wa-al, I don't," confessed the man. "I've got heaps o' conferdence in yer now. We'll creep up."
Then followed something that sorely tried the patience of the boy, for Old Rocks seemed to crawl forward like a snail, taking advantage of every cover that would shield them from the sight of any one in front.
The guide warned Frank to "hug ther ground," and made him creep, and skulk, and wiggle along when there seemed no need of it.
In this way they slowly drew near to the fire, about which figures moved now and then.
"It's ther onery Blackfeet," the guide finally announced. "We hev done a good job so fur ter-day, an' now we wants ter finish it right, you bet!"
"What do you mean to do?" asked Frank.
"Make a bluff," was the answer.
"What kind of a bluff?"
They had reached a point where they could look into the camp and see the savages feasting on some kind of game they had killed and cooked by the fire.
"I'm goin' in thar an' demand ther gal," said the guide.
"Won't that put us in their power?"
"You won't go with me."
"No?"
"No. You'll keep in ther background."
"What for?"
"As a reserve force. You must keep yer peepers open, an' ef you see ther skunks is goin' ter do fer me, jest open up on 'em. I reckon you kin shoot some?"
"Yes."
"Take good keer not ter bore me."
"I will."
"But, ef yer start, pump ther lead ter ther critters ter beat ther Ole Nick."
"I will do it."
"Make sure whar ye're puttin' yer bullets, fer ye don't want ter kill ther leetle gal."
"You may depend on me."
"While you're slingin' lead I'll try ter git ther gal an' git erway with her."
"Won't we get into trouble if I should kill one of these Indians?"
"How?"
"Why, the Blackfeet are peaceable, and it may create a disturbance. We may be hauled over the coals."
"Haul an' be derned! Ther onery varmints hev kidnaped a white gal, an' they're poachin' on forbidden territory, besides bein' off ther reservation. Ef they try ter kill me, it will be a case o' self-defence. I'll allow as how we kin defend ourselves. You do ez I say, an we'll come out all right, dog my cats ef we don't!"
"All right."
"But don't shoot 'less yer hev ter, remember thet."
"I will remember it."
"Ef I hedn't seen ther b'ar, an' seen hwar yer putt five bullets inter him inside ther space uv a silver dollar, I might be skerry 'bout lettin' yer shoot inter thet camp while I wuz thar; but I'll admit ez how I reckon ye kin shoot."
They now crept forward till they were within easy shooting distance of the camp, and then Rocks paused once more, putting his lips close to Frank's ear, and whispering:
"See them rocks down thar?"
The boy nodded.
"Wa-al, jest you creep down behind them an' take yer position ready ter sling lead."
"What are you going to do?"
"Git inter ther camp. I'm goin' ter walk in from t'other side, so they'll be lookin' fer any further danger frum thet quarter. Don't git impatient, fer it'll take me some time ter git round thar. Wait easy."
"I'll wait."
Then the old man crept away into the darkness, and Frank began working his way down to the rocks.
He finally reached the position, and there he waited, being able to look into the camp and see every figure revealed by the flaring fire.
The little girl was there, exhausted by the day of hardships, sleeping soundly. One of the Indians had thrown a greasy blanket over her, so she was protected from the night air, which is always chilly in Yellowstone Park.
Frank's heart throbbed with sympathy as he gazed down on her.
"Poor little Fairy!" he thought. "How she did cling to me! I am ready to wade through fire and water for her. We will save her to-night if we live!"
He found it difficult to restrain his impatience as the time crept slowly away and Old Rocks failed to appear. Some of the Indians rolled themselves in their blankets and prepared to sleep. Others sat and smoked in grim silence.
Frank had spotted Half Hand, and he felt that it would be some satisfaction to send a bullet after the villainous half-blood.
"He is at the bottom of this business," thought the boy. "He would not hesitate at murder."
Nearly an hour passed after Old Rocks crept away before the guide appeared. At last, to the astonishment of Frank and the utter consternation of the Indians, the man seemed to rise up in the very midst of the camp, as if he had suddenly sprouted from the ground.
CHAPTER XXXIII.
THE RESCUE.
A yell of astonishment broke from the throats of the Indians who were awake, and it brought the sleepers out of their blankets in a moment.
With the utmost coolness, Old Rocks stepped toward the fire, sat down on a log near the sleeping child, and took out his black pipe.
"Any o' you fellers got any good smokin' terbacker?" he asked, coolly. "I ain't got northin' left but chawin', an thet's derned pore stuff ter burn."
"Ugh!" grunted the Blackfeet, staring at him in unutterable amazement.
"Hey?" questioned the guide. "Whut did yer say?"
"Where white man come from?" demanded Half Hand, harshly.
"Over yon," was the answer, and Rocks made a sweep of his hand that took in half the horizon.
"What white man want here?"
"Terbacker."
The Indians looked at each other, and then looked at the cool visitor, their amazement not a whit abated.
"Ugh!" they grunted in chorus.
"Wa-al, I'll allow thet you fellers know whut thet means all right," drawled Old Rocks, whimsically; "but dog my cats ef I do! Do I git ther terbacker? ur do I hev ter pull my liver out tryin' ter make chawin' terbacker burn?"
"Ain't got no 'backer," declared Half Hand, sullenly.
