“I never heard of him if he did. But it is only a theory of mine, this living on air. It would be fine, wouldn’t it? Of course it may be impossible—most likely it is. You see, I am not unpractical. I never forget the present. When I soar ahead into the future, I always leave a string by which to find my way back again.” With my surgical instruments it is different. While I have not yet had serious use for them, I do not regret the space they occupy. The thought of them makes me feel good. They are so much life insurance, only, fairer than that last grim game, one is not supposed to die in order to win. Of course, I don’t know how to use them, and what I don’t know about surgery would set up a dozen quacks in prosperous practice. But needs must when the devil drives, and we of the Snark have no warning when the devil may take it into his head to drive, ay, even a thousand miles from land and twenty days from the nearest port.!

“She’s not going ashore,” was Captain Jansen’s answer. 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.

There was something wrong about that shark. It bothered me. It had no right to be there in that deserted ocean. The more I thought about it, the more incomprehensible it became. But two hours later we sighted land and the mystery was cleared up. He had come to us from the land, and not from the uninhabited deep. He had presaged the landfall. He was the messenger of the land. I compromised by subtracting thirty-one seconds from the total of my chronometer’s losing error, and sailed away for Tanna, in the New Hebrides, resolved, when nosing around the land on dark nights, to bear in mind the other seven miles I might be out according to Captain Wooley’s instrument. Tanna lay some six hundred miles west-southwest from the Fijis, and it was my belief that while covering that distance I could quite easily knock into my head sufficient navigation to get me there. Well, I got there, but listen first to my troubles. Navigation is easy, I shall always contend that; but when a man is taking three gasolene engines and a wife around the world and is writing hard every day to keep the engines supplied with gasolene and the wife with pearls and volcanoes, he hasn’t much time left in which to study navigation. Also, it is bound to be easier to study said science ashore, where latitude and longitude are unchanging, in a house whose position never alters, than it is to study navigation on a boat that is rushing along day and night toward land that one is trying to find and which he is liable to find disastrously at a moment when he least expects it. Well, it was blowing half of a small summer gale, when I told Roscoe we’d heave to. Night was coming on. I had been steering nearly all day, and all hands on deck (Roscoe and Bert and Charmian) were tired, while all hands below were seasick. It happened that we had already put two reefs in the big mainsail. The flying-jib and the jib were taken in, and a reef put in the fore-staysail. The mizzen was also taken in. About this time the flying jib-boom buried itself in a sea and broke short off. I started to put the wheel down in order to heave to. The Snark at the moment was rolling in the trough. She continued rolling in the trough. I put the spokes down harder and harder. She never budged from the trough. (The trough, gentle reader, is the most dangerous position all in which to lay a vessel.) I put the wheel hard down, and still the Snark rolled in the trough. Eight points was the nearest I could get her to the wind. I had Roscoe and Bert come in on the main-sheet. The Snark rolled on in the trough, now putting her rail under on one side and now under on the other side.
