"I have thought that such might be the case," said Frank. "In some way he has been wronged by Uric Dugan. He did not seem to know exactly how, but he was sure of it. It was only at times that he seemed deranged, but he did not remember much of his past." "It would be most remarkable if he should turn out to be my father, whom I have believed dead all these years." "It would be a miracle," declared Professor Scotch. "But do you know you can find Water Pocket Canyon again?" "Yes, for I have Ben Barr to guide me. He will take me there." "Well," said the little professor, "I wish you success, but I would not go back there for the worlds, and I absolutely refuse to let my boys go." "I suppose we'll have to humor the professor in this instance," laughed Frank. "Our last escapade came near being fatal for all of us." "You owe your salvation to Professor Septemas Scudmore," declared that individual, importantly. "But for his marvelous invention, the _Eagle_, you would have fallen victims to untamed savages." "Begorra, thot's roight!" nodded Barney. "Th' _'Agle_ is a great birrud." "It is bound to make me famous the world over, and send my name ringing down the corridors of time." "But what of poor Miskel?" asked Frank. "She is heartbroken over the death of her father. She knows nothing of the world at large, and----" "Under the circumstances," said Walter, "I feel that it is my duty to see that she does not come to harm. As long as she wants it, she shall have a home with my folks, if she will accept." "Be aisy, me b'y!" chuckled Barney, roguishly. "It's a swate purty face she has, an' Oi'm thinkin' ye're a bit shtuck on her." "Oh, come!" protested Walter, blushing. "I have known her but four days, and----" "Ye've made good progress, me lad. Oi notice thot you have done firrust-rate comfortin' her. It's an invoite to th' weddin' Oi warnt, an' Oi think Frankie would look foine as th' bist man." "If the wedding ever takes place, you shall be invited." The mystery of Old Solitary remains still, for he was never found; although Walter and Ben Barr did make their way into Water Pocket Canyon once more. The ruins of the Danite village were found, also human bones, picked clean by wolves and vultures. No living thing seemed to remain in the vicinity, and the silence and shadow of death hung over the place. Old Solitary's cave was deserted. It is possible that, after all, the strange man fell a victim to the savages; but it is more likely that, being deranged, he was spared by them, and they made him a great medicine man among them. Perchance he is living with them to-day on the Navajo reservation. "I think we are well out of that," said Frank, when it was all over. "I want no more of the murderous Danites." "Humph, I told you to keep off," grunted Professor Scotch. "But you'll soon run into equal peril, I'll warrant." "No, professor--only sight-seeing in the future." "And where?" "Yellowstone Park, the great National reservation."
