I am ashamed to say we all looked up in surprise, but so it was.

"Well," my brother continued, "by good luck, I happen to have a prayer-book in my pocket and I am going to read a bit of the service and the ninety-first psalm."

Very straight and stiff, he pulled out a battered little book and began. This is not a scene I wish to linger on, but you will understand my reasons.

After the last sonorous Amen, Bernard said:

"Well, we've said our prayers and we've thought of our wives and—and of our girls. That is all I have got to say."

He nodded to Scarlett and a shrill whistle—the trumpet of the Navy—rang and rattled through the tube.

The two boys and Scarlett went forward to the torpedoes. Adams was called down from the steering wheel to assist Bosustow at the engines. My brother ordered me up into the conning-tower by his side.

"You'll be of more help to me here," he said. "I shall control the ship entirely myself, but I may want your assistance. Watch me carefully in case I have to go below at any moment."

At twelve-thirty precisely, the gasolene engines were stopped. Bernard filled the tanks, slightly deflected the horizontal rudders, and we dived into the smooth, green wall of an approaching swell and sank to ten feet. The light was switched off, the periscope rose, and we bent over the white table, white no longer.

At five minutes to one the picture of the empty sea was altered. Our range of vision was about two miles, and at that distance to the north-east we observed a cloud of smoke upon the horizon.
