“H’m!” said Pierre. “I can’t see it. You have made trouble enough for me already.”

“And you haven’t seen the last of me yet,” added Frank.

“I know it. I told you that I should come back to you, didn’t I?”

“I mean that you will meet me under very different circumstances. We will change places in less than twenty-four hours.”

Frank said this with no other object in view, than to let Pierre know that he still kept up a brave heart, if the future was dark before him. There was nothing in his prospects, just then, to encourage the hope that he and his enemy would “change places,” and he little dreamed that such would be the case; but, after all, something very like it did happen, and in less than half the time Frank had mentioned. Pierre, however, happy in the belief that his dreams of wealth were about to be realized, had no misgivings. He laughed at his prisoner’s warning, and springing into his saddle, disappeared in the darkness. Frank listened to the sound of his horse’s feet until it died away in the distance, and then rested his aching head against the tree, and thought over his situation. What an eventful day it had been! What astonishing adventures had been crowded into the short space of ten hours! Frank’s mind was in a perfect whirl; and, if he could have freed his hands, he would have pinched himself to see if he was really wide awake. But, after all, he knew that the events of the day were no dream—his aching limbs and throbbing head assured him of that. The fight with Old Davy, Archie’s mishap, and his mysterious disappearance at Don Carlos’ rancho, the death of the trapper, and the unexpected encounter with Pierre Costello—all were realities. It was no dream, either, that he had been bound to a tree and left in those dark woods; and it was equally certain that he was not the only living thing there. He heard a stealthy step on the leaves, and a moment afterward, saw a pair of eyes, which shone like two coals of fire, glaring at him from a thicket not far distant.

“It’s a panther!” exclaimed Frank, trembling all over with terror, and much more alarmed now than he had been when he found himself in the power of his old enemy; “and here I am perfectly helpless. Hi! hi!”

Acting upon his first impulse, which was to frighten away his disagreeable neighbor, he uttered a series of yells which awoke the echoes far and near. The result greatly astonished him. An answering shout came from the farther end of the ravine, and hasty footsteps were heard approaching. Frank’s heart beat high with hope. Had friends been following him? More likely they were some of the settlers, who had been out hunting, and were returning to their homes. In either case he would soon be free once more, and his first care would be to show Pierre that, if he had come back to the settlement, expecting to have things all his own way, he had reckoned without his host. He shouted again, and the eyes in the bushes disappeared, and he heard the panther bounding up the mountain.

“Hallo!” called a voice through the darkness.

“Hallo!” replied Frank. “This way. Here I am.”

The unknown persons were prompt to answer the call, and came through the bushes with all possible speed. Presently, Frank saw two dark forms approaching, and in a few seconds they were close at his side, and peering into his face. Why was it that he did not speak to them and tell them what had happened to him? Simply because there was no need of it. The men knew quite as much about it as he did. He had seen them before, and knew that they were members of Don Carlos’ band. The first words they uttered explained their presence there, and told Frank that they perfectly understood the matter.
