“Bosh!” snaps my logical mind. “Lecky says—” The difference between the two positions was something like eighty miles. Yet we knew we had not travelled twenty miles. Now our figuring was all right. We went over it several times. What was wrong was the observations we had taken. To take a correct observation requires practice and skill, and especially so on a small craft like the Snark. The violently moving boat and the closeness of the observer’s eye to the surface of the water are to blame. A big wave that lifts up a mile off is liable to steal the horizon away.!

“Poor little chap! poor little chap!” But alas and alack and lucky for me, I read on. I discovered that the compass, that trusty, everlasting friend of the mariner, was not given to pointing north. It varied. Sometimes it pointed east of north, sometimes west of north, and on occasion it even turned tail on north and pointed south. The variation at the particular spot on the globe occupied by the Snark was 9° 40′ easterly. Well, that had to be taken into account before I gave the steering course to the man at the wheel. I read:

Also, as a preliminary, we attended a feast, where one Taiara Tamarii, the son of an Hawaiian sailor who deserted from a whaleship, commemorated the death of his Marquesan mother by roasting fourteen whole hogs and inviting in the village. So we came along, welcomed by a native herald, a young girl, who stood on a great rock and chanted the information that the banquet was made perfect by our presence—which information she extended impartially to every arrival. Scarcely were we seated, however, when she changed her tune, while the company manifested intense excitement. Her cries became eager and piercing. From a distance came answering cries, in men’s voices, which blended into a wild, barbaric chant that sounded incredibly savage, smacking of blood and war. Then, through vistas of tropical foliage appeared a procession of savages, naked save for gaudy loin-cloths. They advanced slowly, uttering deep guttural cries of triumph and exaltation. Slung from young saplings carried on their shoulders were mysterious objects of considerable weight, hidden from view by wrappings of green leaves. In years and years no sailing vessel has attempted this traverse, and we found ourselves in the midst of one of the loneliest of the Pacific solitudes. In the sixty days we were crossing it we sighted no sail, lifted no steamer’s smoke above the horizon. A disabled vessel could drift in this deserted expanse for a dozen generations, and there would be no rescue. The only chance of rescue would be from a vessel like the Snark, and the Snark happened to be there principally because of the fact that the traverse had been begun before the particular paragraph in the sailing directions had been read. Standing upright on deck, a straight line drawn from the eye to the horizon would measure three miles and a half. Thus, seven miles was the diameter of the circle of the sea in which we had our centre. Since we remained always in the centre, and since we constantly were moving in some direction, we looked upon many circles. But all circles looked alike. No tufted islets, gray headlands, nor glistening patches of white canvas ever marred the symmetry of that unbroken curve. Clouds came and went, rising up over the rim of the circle, flowing across the space of it, and spilling away and down across the opposite rim. It was at Suva, in the Fijis, that I discharged my third and last captain and took up gain the rôle of amateur navigator. I had essayed it once before, under my first captain, who, out of San Francisco, jumped the Snark so amazingly over the chart that I really had to find out what was doing. It was fairly easy to find out, for we had a run of twenty-one hundred miles before us. I knew nothing of navigation; but, after several hours of reading up and half an hour’s practice with the sextant, I was able to find the Snark’s latitude by meridian observation and her longitude by the simple method known as “equal altitudes.” This is not a correct method. It is not even a safe method, but my captain was attempting to navigate by it, and he was the only one on board who should have been able to tell me that it was a method to be eschewed. I brought the Snark to Hawaii, but the conditions favoured me. The sun was in northern declination and nearly overhead. The legitimate “chronometer-sight” method of ascertaining the longitude I had not heard of—yes, I had heard of it. My first captain mentioned it vaguely, but after one or two attempts at practice of it he mentioned it no more.
