Frank was astonished. He gazed earnestly at the medicine-man, who began singing his low, monotonous song, at the same time fumbling with his odd-looking mask, which he soon removed, revealing to Frank's view the honest countenance of old Bob Kelly. Checking the boy's exclamation of astonishment by an emphatic motion of his hand, the trapper, still humming his song, proceeded to divest himself of the other articles of his disguise; and, as fast as he removed them from his own person, he put them upon Frank, who submitted wonderingly to the operation. In a few minutes he was rigged out in the medicine-man's dress; and, if he had only known it, he looked hideous enough to frighten any body.

"Now, then," said old Bob, in a scarcely-audible whisper, "be off with you. Creep under them skins, an' make yourself skeerce about here, sudden. Thar aint no danger, if you'll only think so. You're a medicine-man now, an' you can go all over the village an' into every lodge, an' nobody won't say a word to you. I'll take care of myself."

The old trapper spoke these words hurriedly, and, pulling Frank off the buffalo robes, stretched himself upon them. Frank would have lingered to ask some instructions concerning the manner in which he ought to conduct himself, and what he ought to do if the guard allowed him to pass out of the lodge, but Bob motioned him impatiently to be off. Calling all his courage to his aid, he lifted the skins at the back of the lodge and crawled out. The guard looked down at him, and then turned away his head as if he did not care to see him; and Frank, throwing himself upon his hands and knees, and imitating as nearly as possible the actions of the medicine-man, hurried off into the darkness.


CHAPTER VII.

IN THE MOUNTAINS.

"Well, this beats me completely. That old medicine-man that Archie and I wanted to shoot so badly was Bob Kelly; and, of course, he did not make a mistake when he cut that bark with his tomahawk—he did it on purpose. Didn't he play his part well? The old fellow must have a steady hand to send those weapons so close to Dick without hitting him. Where did he get this disguise, I wonder; and how is he going to escape from that lodge? This night's work is a little ahead of any thing I ever heard of."

Frank was sitting on the ground in a thicket of bushes on the outskirts of the village, where he had concealed himself, to obtain a few minutes' rest, and to decide what he should do next. He had passed through the camp in safety, and without attracting especial attention from any of the Indians. He had met several warriors on his way, but his disguise was complete, and they, supposing him to be the medicine-man, stepped aside to let him pass, and did not trouble themselves to take a second look at him. He had been emboldened by his success thus far, and a daring project had entered his head. It was to go back to the village, and find and liberate Archie.

There were a good many dangers and difficulties to be overcome in carrying out this plan. The outlaw had said that it was his intention to take Archie to his lodge, where he knew he would be safe; but Frank did not know where that lodge was. And suppose, if he succeeded in finding it, that Black Bill and his companions should be there guarding their prisoner! What would they do to him if they caught him prowling around? Frank did not care to enrage them, for he knew what manner of men they were; but still he was determined that he would not leave his cousin to his fate without making at least an attempt to save him. The village was nearly deserted, except by the women and children, and he could scarcely encounter more danger there than he would in attempting to find his way to the valley. The mountains were filled with Indians, who were searching for the trapper, and he could not hope to avoid meeting some of them. His disguise would protect him as long as he remained near the village, but wouldn't the warriors suspect something if they found him making his way toward the fort?

"I'll be in danger, no matter what I do," said Frank, to himself; "and I am going to try to find Archie. If he isn't liberated I would just as soon be recaptured as not, for I could never live without him. How would I feel to go back to our hunting and fishing grounds about Lawrence, and know that he was kept a prisoner among these savages? I won't do it. If he must stay here, I shall stay with him."
