"You have saved _my_ boy, my Indian friend, and you will always be _my_ friend," returned Luke. "Well, Luke, what shall we do? I have done my errand and delivered the bonds. I suppose I ought to go back to Emmonsville." "We will go back. I have found you, and have no more to do here." "Shall we walk?" "No, it is too far. There is a stable a little way from here; I will hire a conveyance, and our Indian friend will perhaps be willing to drive us over." The Indian expressed his willingness, and the three were soon on their way through the woods. They met with no adventure, nor did they fear any, for it would have required a brave man to attack two such stalwart persons as the Indian and the Quaker detective. Leaving them for the present, we will go back to the cave from which Ernest had made so unceremonious a departure. Frank slept for two hours, but at length opened his eyes, expecting to see Ernest sitting at his bedside. He looked in vain. There was no one in the room. This did not surprise him much, however. He thought Ernest might have gone into the next apartment. "Ernest!" he cried, but his call received no response. The little boy got out of bed and looked about, but his search was vain. So he went into the kitchen, where he found Juba engaged in some domestic work. "Juba," he said, "where is Ernest." "I don't know, chile. Isn't he in the big room?" "No, Juba. I went to sleep, and when I woke up he was gone." "Lor', chile, he round somewhere. You look round, and maybe you find him." But Frank was doomed to disappointment. He sat down ready to cry. He felt very lonely. He had not realized how much he enjoyed Ernest's company. "I don't know where he can have gone, Juba. Do you think he's gone and left me?" "I can't tell, chile. Wait till your papa comes home. He will find him." Frank had to wait an hour and a half before his father's return. All this time he was buoyed up by the hope that Ernest would come back. He was continually watching the portal to see if the runaway would not come, but in vain. James Fox entered the room with grave face and heavy step. He had not heard of his brother's escape, and thought him still an inmate of Crampton jail. He looked about for his young captive. "Where is Ernest, Frank?" he asked. "I don't know, papa. I miss him ever so much," said the little boy tearfully. "But he must be somewhere about. When did you miss him?" "He went away when I was asleep." The outlaw's suspicions were aroused. "I will look for him," he said. But Ernest was in none of the rooms, nor could Juba give any account of him. "Did you walk with him into the interior of the cave, Frank?" he asked. "Yes, papa." "Ha, that explains it. Go with me, and tell me just where you went." The little boy led the way through the vacant apartments till he reached the one through which the light came from above.
