“Ah,” said the Swede, turning away, laughing a little, “you can explain everything.” “The same wind that caught the steering paddle and flung it so near the bank that it fell in with the next lump that crumbled,” I called out after him, absolutely determined to find an explanation for everything he showed me. “I see,” he shouted back, turning his head to look at me before disappearing among the willow bushes. Once alone with these perplexing evidences of personal agency, I think my first thoughts took the form of “One of us must have done this thing, and it certainly was not I.” But my second thought decided how impossible it was to suppose, under all the circumstances, that either of us had done it. That my companion, the trusted friend of a dozen similar expeditions, could have knowingly had a hand in it, was a suggestion not to be entertained for a moment. Equally absurd seemed the explanation that this imperturbable and densely practical nature had suddenly become insane and was busied with insane purposes. Yet the fact remained that what disturbed me most, and kept my fear actively alive even in this blaze of sunshine and wild beauty, was the clear certainty that some curious alteration had come about in his _mind_—that he was nervous, timid, suspicious, aware of goings on he did not speak about, watching a series of secret and hitherto unmentionable events—waiting, in a word, for a climax that he expected, and, I thought, expected very soon. This grew up in my mind intuitively—I hardly knew how. I made a hurried examination of the tent and its surroundings, but the measurements of the night remained the same. There were deep hollows formed in the sand I now noticed for the first time, basin-shaped and of various depths and sizes, varying from that of a tea-cup to a large bowl. The wind, no doubt, was responsible for these miniature craters, just as it was for lifting the paddle and tossing it towards the water. The rent in the canoe was the only thing that seemed quite inexplicable; and, after all, it _was_ conceivable that a sharp point had caught it when we landed. The examination I made of the shore did not assist this theory, but all the same I clung to it with that diminishing portion of my intelligence which I called my “reason.” An explanation of some kind was an absolute necessity, just as some working explanation of the universe is necessary—however absurd—to the happiness of every individual who seeks to do his duty in the world and face the problems of life. The simile seemed to me at the time an exact parallel. I at once set the pitch melting, and presently the Swede joined me at the work, though under the best conditions in the world the canoe could not be safe for traveling till the following day. I drew his attention casually to the hollows in the sand. “Yes,” he said, “I know. They’re all over the island. But _you_ can explain them, no doubt!”
