"Where are we?" I said. "What has happened?"
"You've had a very good sleep, John. You went off like a log directly I had the hammock slung. It was necessary, too, or you'd never be fit for what is coming."
"Have we started?"
"Started!" he grinned. "We're thirty miles away from Morstone Marshes, abreast of Skegness, I should judge, which, as far as I can calculate, is about sixty miles to the westward—and heading straight out into the North Sea. We're just crossing the line of the Rotterdam boats from Hull."
"But there is no movement!"
"No, my son, because we're twenty-five feet under water, that's why. Now, you had better come and look round the boat; I shall have to explain everything to you and show you what you will have to do later on." He turned to the Dicksons. "You come, too," he said, "and if ever the three of you have your wits about you, have them now. You've got to learn in an hour or two what it takes an ordinary seaman six months to learn—or part of it, at any rate."
I am not going to describe everything I saw in detail. This is a story of action, and I always skip the descriptive parts in books, myself. The Johnnies only put them in to fill up. I expect they are paid so much a page, if the truth were known! Still, I must try and give some picture of the strange and unfamiliar world in which I found myself. Here I was sailing under the sea for all the world like someone in Jules Verne, experiencing something that only the tried men of the navies ever know.
I was in a long, narrow tunnel, most brilliantly lit. The air was warm and close, tainted a little with a faint suggestion of chemical fumes. It was rather like being in a chemist's shop in winter time when a large fire is burning.
Immediately to my right, the German waiter was busy over a little electric stove, in a doorless compartment not bigger than a bathing machine, Pots and pans hung above him and there were shelves covered with wire netting containing stores of food. We passed him, and I judged, from the breadth from side to side, that we were standing almost in the middle of the submarine.
Upon white-painted gratings, my brother's sailors moved here and there with bare feet, quiet and alert in their jumpers. The light was caught by, and reflected again, from innumerable pieces of shining machinery, brass and silver and dull bronze. There was a tension both of physical atmosphere and mental excitement, strange and unnatural to me, but which those who go beneath the waters and explore the mysterious deep always have with them.
