But that something that sits in judgment upon the findings of our brain, and, in lofty disregard of us, accepts or rejects our most profound conclusions, refused this answer. It was too superficial. It was not, in short, an answer. It did not in any way explain the strange power that this lad had exerted over the Doctor.
"Me," he said to himself, "a hard old man calloused by years of professional contact with mankind and consequent knowledge of their general cussedness! Huh! I have helped too many hundreds of children into this world, and have carried too many of them through the measles, whooping-cough, chicken-pox and the like to be so moved by a mere boy."
The Thompsons could have told him about the lad and his people, but the Doctor instinctively shrank from asking them. He felt that he did not care to be told about the boy—that in truth no one could tell him about the boy, because he already knew the lad as well as he knew himself. Indeed the feeling that he already knew the boy was what troubled the Doctor; more, that he had always lived with him; but that he had never before met him face to face. He felt as a blind man might feel if, after living all his life in closest intimacy with someone, he were suddenly to receive his sight and, for the first time, actually look upon his companion's face.
In the years that have passed since that day the Doctor has learned that the lad was to him, not so much a mystery as a revelation—the revelation of an unspoken ideal, of a truth that he had always known but never fully confessed even to himself, and that lies at last too deeply buried beneath the accumulated rubbish of his life to be of any use to him or to others. In the boy he met this hidden, secret, unacknowledged part of himself, that he knows to be the truest, most precious and most sacred part, and that he has always persistently ignored even while always conscious that he can no more escape it than he can escape his own life. In short, Dan Matthews is to the Doctor that which the old man feels he ought to have been; that which he might have been, but never now can be.
It was still early in the forenoon of the following day when the Doctor heard a cheery hail, and the boy came riding out of the brush of the little ravine to meet his friend who was waiting on the river bank. As the lad sprang lightly to the ground, and, with quick fingers, took some things from the saddle, loosed the girths and removed the pony's bridle, the physician watched him with a slight feeling of—was it envy or regret? "You are early," he said.
The boy laughed. "I would have come earlier if I could," Then, dismissing the little horse, he turned eagerly, "Have you been there yet—to that place up the river?"
"Indeed I have not," said the Doctor, "I have been waiting for you to show me."
He was delighted at this, and very soon was leading the way along the foot of the bluff to his favorite fishing ground.
It is too much to attempt the telling of that day: how they lay on the ground beneath the giant-limbed cottonwoods, and listened to the waters going past; how they talked of the wild woodland life about them, of flower and tree, and moss and vine, and the creatures that nested and denned and lived therein; how they caught a goodly catch of bass and perch, and the Doctor, pulling off his boots, waded in the water like another boy, while the hills echoed with their laughter; and how, when they had their lunch on a great rock, an eagle watched hungrily from his perch on a dead pine, high up on the top of the bluff.
When the shadow of the mountain was come once more and in answer to the boy's whistle the black pony had trotted from the brush to be made ready for the evening ride, the Doctor again watched his young companion wistfully.
