Unceasingly our binoculars pierced the gray dusk of daybreak. Suddenly a shiver went through my body when—only a second immovable and in intense suspense—a dark shadow within range of the spy-glass made me jump. The shadow grew and became larger, like a giant on the horizon—one mast; one, two, three, four funnels—a destroyer.

A quick command—I leap down into the tower. The water rushes into the diving tanks. The conning tower covers slam tight behind me—and the agony which follows tries our patience, while we count seconds with watches in hand until the tanks are filled, and the boat slips below the sea.

Never in my life did a second seem so long to me. The destroyer, which is not more than two thousand meters distant from us, has, of course, seen us, and is speeding for us as fast as her forty thousand horse power can drive her. From the guns mounted on her bow flash one shot after another aimed to destroy us.

Good God! If he only does not hit! Just one little hit, and we are lost! Already the water splashes on the outside of the conning tower up to the glass windows through which I see the dark ghost, streaking straight for us. It is terrifying to hear the shells bursting all around us in the water. It sounds like a triphammer against a steel plate, and closer and closer come the metallic crashes. The rascal is getting our range.

There—the fifth shot—the entire boat trembles—then the deceitful daylight disappears from the conning-tower window. The boat obeys the diving rudder and submerges into the sea.

A reddish-yellow light shines all around us; the indicator of the manometer, which measures our depth, points to eight meters, nine meters, ten meters, twelve meters. Saved!

III—HOW IT FEELS TO PLUNGE BENEATH THE SEAS

What a happy, unexplainable sensation to know that you are hiding deep in the infinite ocean! The heart, which had stopped beating during these long seconds because it had no time to beat, again begins its pounding.
