The Peterhof’s engines were antiquated, break-downs had occurred before, and our two engineers, I learnt, would be able to effect a repair. Twenty-four hours’ labour would set us going again—it turned out to be only a slightly over-optimistic prophecy—and meanwhile, we were free to admire, as best we might, the somewhat monotonous beauties of the Atlantic.

There was not a breath of wind; the sun blazed from a cloudless sky; as long as the Peterhof had been in motion we had considered the temperature fairly cool, but now that her motion was arrested the heat became very noticeable. The sea was, in a sense, absolutely smooth; but its smoothness did not imply flatness, any more than the smoothness of a carpet’s pile implies flatness if the carpet is being shaken. On the contrary, the Peterhof was rolling upon the undulations of a heavy ground-swell. The surface of that ground-swell was without a wrinkle, polished and glossy like lacquer; but its hills and its dales were gigantically high and deep; far higher and far deeper than I had realised until the engines relinquished their task of propelling us athwart them. Now, lying helpless upon the water, we swooped up to a glazed summit, swooped down to the bottom of a satiny gulf, swooped up again and down again, in a splendid, even oscillation—and (this was what seemed so extraordinary to a landsman)—in absolute silence. It was uncanny. Those fabulous billows never broke. There was not even a hiss of foam against the side of the steamer. The Peterhof just tobogganned down one stupendous gradient and up the next as though she had been sliding on oil.

The thing fascinated me. I stood by the rail, revelling in this prodigous sea-saw, and only gradually did it dawn upon me that we were not really rushing down one slant and up the next, we were only being lifted up and down vertically.

This discovery sounds foolish, but I can’t tell you how it excited me. I got an empty biscuit tin from the steward and threw it into the sea, as far as I could, and then watched it floating. You’d have said that that biscuit tin would have been drawn away by the strength of the swell, or else dashed against the Peterhof’s side; instead it simply sat there at exactly the spot where it had fallen; and an hour after I had thrown it into the water it had shifted, perhaps, only six or eight inches nearer the steamer.

A project was forming in my mind. I looked at the water. It was a peculiar, vitreous green, closer under the steamer, was transparent to the depth of many feet. Beneath my shoe-soles the poop was hot; over side, the sea looked inexpressibly inviting. And on a sudden I turned to the drowsing Captain and exclaimed: “I want to bathe.”

“To bathe?” The Captain gazed at me.

“Why not?”

The Captain yawned out some lethargic suggestion to the effect that to bathe would be dangerous because of the depth—as though I’d be more apt to drown in three miles of water than in three fathoms.

Seafaring people are odd in that way—I don’t mean in their ignorance of swimming, though, to be sure, the average sailor is seldom a swimmer. They’re so—how shall I express it?—so unenterprising. In the midst of adventure and romance they are stirred by no recognition either of the adventures or the romantic.

I was a city-bred youngster, who had never been out of hail of the homeland before, and I possessed more enterprise in my little finger than that far-travelled Captain had in the whole of his weather-worn, hulking lump of a carcass. I wanted to bathe. I wanted to bathe in the mid-Atlantic. I had learnt to bathe in the public swimming-bath near my old school, and now I wanted to try a swimming-bath three miles deep and tilting continuously at an angle of I don’t know how many degrees. The notion was gorgeous.
