And so the four sat in silence by the fire.  Above, a few great stars shone warmly.  Here and there the rapids flashed white through the gloom.  From a huge pine on the other side of the pool a horned owl challenged the darkness with his ponderous call.

Suddenly the man broke the silence,—­broke it with a question which led to a remarkable conversation, and a tragical result.  And the question was this:—­

“Friend, answer me this question:  If a man take a life, should he give his own life in atonement for the dreadful deed?”

“If a man take a life, should he give his own life in atonement for the dreadful deed?”

Such was the question that the man asked.  He was looking at the trapper at the time,—­looking at him steadily; but the sound of his voice as he put the question did not seem to give personal direction to the solemn interrogation; it seemed rather the echo of a reflection, as if his own mind in its communings had come upon the terrible question, and the words, without volition of his own, which framed it into speech, had passed out of his mouth.

He was looking at the trapper, as we said, and the trapper was looking into the fire,—­the light of which, that came and went in flashes, brought distinctly out the settled gravity of the features, and the rugged but grand proportions of the head.  There is no better light in which to see an old man’s face than the fitful firelight; and no better background than that which the darkness makes.

One would have thought that the interrogation was not heard, for on the trapper’s face there showed no line of change.  The girl remained looking steadfastly into the face of the questioner, and Herbert made no response.

“I asked you a question, old trapper,” said the man; “a question which reaches to the depths of human responsibility, and points to the heights of human sacrifice.  In the old days, the wisdom of the world was with those who lived with Nature.  Your head is white, and you tell me you have lived in the woods since you were a boy.  You have seen war; have stood in battle; have slain your man, and made many graves of those you have slain.  Have you wisdom?  Are you able to answer the question I have asked you?”

“I have, as ye say,” answered the trapper, “ben in wars.  I’ve stood in battle; I’ve slain men; I’ve buried those I have slain; I know what it is to take a human creeter’s life, and I think I know where the right to do the deed stops and where it begins.”

“Where does it begin?” asked the man; “where does the right to take human life begin?”

The words came forth slowly and heavy-weighted with meaning.  It was evident that the question which the man asked was not asked as one interrogates, but as one puts a question that has personal application to himself.  The trapper felt this.  He looked into the man’s face, and studied his countenance a moment; noted the breadth of brow, the large, deep-set eyes, the fine curvature of the chin and cheek; saw the beauty and splendor of it; saw what some might not have seen,—­both the beauty of its peaceful mood and the terribleness of the wrath that might surge out of it,—­saw all this, and without answering the question, said simply,—­
