After all it was nothing very alarming--a mere sound, and that was all. I cannot expect that any one reading this, if any one ever should read it, will sympathise with my feelings, or realise the effect which it produced upon me at the time. Supper was over, and I had gone on deck to have a quiet pipe before turning in. The night was very dark--so dark that, standing under the quarter-boat, I was unable to see the officer upon the bridge. I think I have already mentioned the extraordinary silence which prevails in these frozen seas. In other parts of the world, be they ever so barren, there is some slight vibration of the air--some faint hum, be it from the distant haunts of men, or from the leaves of the trees, or the wings of the birds, or even the faint rustle of the grass that covers the ground. One may not actively perceive the sound, and yet if it were withdrawn it would be missed. It is only here in these Arctic seas that stark, unfathomable stillness obtrudes itself upon you in all its gruesome reality. You find your tympanum straining to catch some little murmur, and dwelling eagerly upon every accidental sound within the vessel. In this state I was leaning against the bulwarks when there arose from the ice almost directly underneath me a cry, sharp and shrill, upon the silent air of the night, beginning, as it seemed to me, at a note such as prima donna never reached, and mounting from that ever higher and higher until it culminated in a long wail of agony, which might have been the last cry of a lost soul. The ghastly scream is still ringing in my ears. Grief, unutterable grief, seemed to be expressed in it, and a great longing, and yet through it all there was an occasional wild note of exultation. It shrilled out from close beside me, and yet as I glared into the darkness I could discern nothing. I waited some little time, but without hearing any repetition of the sound, so I came below, more shaken than I have ever been in my life before. As I came down the companion I met Mr. Milne coming up to relieve the watch. “Weel, Doctor,” he said, “maybe that’s auld wives’ clavers tae? Did ye no hear it skirling? Maybe that’s a supersteetion? What d’ye think o’t noo?” I was obliged to apologise to the honest fellow, and acknowledge that I was as puzzled by it as he was. Perhaps to-morrow things may look different. At present I dare hardly write all that I think. Reading it again in days to come, when I have shaken off all these associations, I should despise myself for having been so weak. September 18th.--Passed a restless and uneasy night, still haunted by that strange sound. The Captain does not look as if he had had much repose either, for his face is haggard and his eyes bloodshot. I have not told him of my adventure of last night, nor shall I. He is already restless and excited, standing up, sitting down, and apparently utterly unable to keep still.
