There were no other women on board: only British officers and the turbaned and imposing Indians. The day was bright, exceedingly cold. The boat went at top speed, her lifeboats slung over the sides and ready for lowering. There were lookouts posted everywhere. I did not think they attended to their business. Every now and then one lifted his head and looked at the sky or at the passengers. I felt that I should report him. What business had he to look away from the sea? I went out to the bow and watched for periscopes. There were black things floating about. I decided that they were not periscopes, but mines. We went very close to them. They proved to be buoys marking the Channel. I hated to take my eyes off the sea, even for a moment. If you have ever been driven at sixty miles an hour over a bad road, and felt that if you looked away the car would go into the ditch, and if you will multiply that by the exact number of German submarines and then add the British Army, you will know how I felt. Afterward I grew accustomed to the Channel crossing. I made it four times. It was necessary for me to cross twice after the eighteenth of February, when the blockade began. On board the fated Arabic, later sunk by a German submarine, I ran the blockade again to return to America. It was never an enjoyable thing to brave submarine attack, but one develops a sort of philosophy. It is the same with being under fire. The first shell makes you jump. The second you speak of, commenting with elaborate carelessness on where it fell. This is a gain over shell number one, when you cannot speak to save your life. The third shell you ignore, and the fourth you forget about--if you can. Seeing me alone the captain asked me to the canvas shelter of the bridge. I proceeded to voice my protest at our change of destination. He apologised, but we continued to Boulogne. "What does a periscope look like?" I asked. "I mean, of course, from this boat?" "Depends on how much of it is showing. Sometimes it's only about the size of one of those gulls. It's hard to tell the difference." I rather suspect that captain now. There were many gulls sitting on the water. I had been looking for something like a hitching post sticking up out of the water. Now my last vestige of pleasure and confidence was gone. I went almost mad trying to watch all the gulls at once. "What will you do if you see a submarine?' "Run it down," said the captain calmly. "That's the only chance we've got. That is, if we see the boat itself. These little Channel steamers make about twenty-six knots, and the submarine, submerged, only about half of that. Sixteen is the best they can do on the surface. Run them down and sink them, that's my motto." "What about a torpedo?" "We can see them coming. It will be hard to torpedo this boat--she goes too fast."
