He stooped, and, I fancied with some surprise, lifted a glass vessel from beneath a handful of withered stalks. He shook them out gently, laid the fresh blossoms in their place, and a faint fragrance rose like incense through the coolness of the dew. Then he turned, and I followed him to where we had left the horses. "There are still kind souls on this earth, and one of them placed that vessel under the last flowers I left. You have a partial answer to your question now."

I bent my head, and seeing that he was not averse to speech, said quietly: "You come here sometimes? It is a long journey."

"Yes," was the answer; and Boone's voice vibrated. "She who sleeps there gave up a life of luxury for me; and is a three-hundred-mile journey too much to make, or a summer night too long to watch beside her? I am drawn here, and there are times when one wonders if it is possible for us to rise into partial communion with those who have passed into the darkness before us."

"It is all," I answered gravely, "a mystery to me. Can you conceive such a possibility?"

"Not in any tangible shape to such as I, but this at least I know. In spite of the destruction of the mortal clay, when I can see my way no further, and lose courage in my task, fresh strength comes to me after a night spent here."

"Your task?" I said. "I guessed that there was a motive behind your wanderings."

"There is one," and Boone's voice rose to its natural level. "The wagon journeys suit it well. Had Lane ruined me alone I should have tried to pay my forfeit for inexperience and the risk I took gracefully; but when I saw the woman, who had lain down so much for me, fading day by day that he might add to his power of oppressing others the money which would have saved her life, the case was different. The last part he played in the pitiful drama was that of murderer, and the loss he inflicted on me one that could never be forgiven."

"And you are waiting revenge?" I asked.

"No." Boone looked back towards the crest of the rise. "At first I did so, but it is justice that prompts me now. I have a full share of human passions, and once I lay in wait for him with a rifle—my throat parched and a fire of torment in my heart; but when he passed at midnight within ten paces I held my hand and let him go. Perhaps it was because I could not take the life of even that venomous creature in cold blood, and feared he would not face me. Perhaps another will was stronger than my own, for, with every purpose strained against what seemed weakness, it was borne in on me that I could not force him to stand with a weapon, and that I dare not kill him groveling. Then the power went out of me, and I let him go. Yet I have twice lain long hours in hot sand under a deadly rifle fire, Ormesby. There are many mysteries, and as yet it is very little that we know."

"But you are following him still, are you not?" I asked. And Boone continued: "As I said, it is for justice, and it was here I learned the difference. I would not take the reptile's life unless he met me armed in the daylight, which he would never do; but for the sake of others—you and the rest, whose toil and blood he fattens on—I am waiting and working for the time when, without a crime, it may be possible to end his career of evil."
