Then one day came the word that we were about to round the Horn and that von Schoenvorts had taken it into his fool head to cruise up along the Pacific coast of North America and prey upon all sorts and conditions of merchantmen.

"I'll put the fear of God and the Kaiser into them," he said.

The very first day we entered the South Pacific we had an adventure.

It turned out to be quite the most exciting adventure I had ever encountered. It fell about this way. About eight bells of the forenoon watch I heard a hail from the deck, and presently the footsteps of the entire ship's company, from the amount of noise I heard at the ladder. Some one yelled back to those who had not yet reached the level of the deck: "It's the raider, the German raider Geier!"I saw that we had reached the end of our rope. Below all was quiet--not a man remained. A door opened at the end of the narrow hull, and presently Nobs came trotting up to me. He licked my face and rolled over on his back, reaching for me with his big, awkward paws. Then other footsteps sounded, approaching me.

I knew whose they were, and I looked straight down at the flooring.

The girl was coming almost at a run--she was at my side immediately.

"Here!" she cried. "Quick!" And she slipped something into my hand.

It was a key--the key to my irons. At my side she also laid a pistol, and then she went on into the centrale. As she passed me, I saw that she carried another pistol for herself. It did not take me long to liberate myself, and then I was at her side.

"How can I thank you?" I started; but she shut me up with a word.

"Do not thank me," she said coldly. "I do not care to hear your thanks or any other expression from you. Do not stand there looking at me. I have given you a chance to do something--now do it!" The last was a peremptory command that made me jump.

Glancing up, I saw that the tower was empty, and I lost no time in clambering up, looking about me. About a hundred yards off lay a small, swift cruiser-raider, and above her floated the German man-of-war's flag. A boat had just been lowered, and Icould see it moving toward us filled with officers and men.

The cruiser lay dead ahead. "My," I thought, "what a wonderful targ--"I stopped even thinking, so surprised and shocked was I by the boldness of my imagery. The girl was just below me. I looked down on her wistfully. Could I trust her? Why had she released me at this moment? I must! I must! There was no other way.

I dropped back below. "Ask Olson to step down here, please,"I requested; "and don't let anyone see you ask him."She looked at me with a puzzled expression on her face for the barest fraction of a second, and then she turned and went up the ladder. A moment later Olson returned, and the girl followed him. "Quick!" I whispered to the big Irishman, and made for the bow compartment where the torpedo-tubes are built into the boat; here, too, were the torpedoes. The girl accompanied us, and when she saw the thing I had in mind, she stepped forward and lent a hand to the swinging of the great cylinder of death and destruction into the mouth of its tube. With oil and main strength we shoved the torpedo home and shut the tube; then I ran back to the conning-tower, praying in my heart of hearts that the U-33 had not swung her bow away from the prey. No, thank God!

Never could aim have been truer. I signaled back to Olson:

"Let 'er go!" The U-33 trembled from stem to stern as the torpedo shot from its tube. I saw the white wake leap from her bow straight toward the enemy cruiser. A chorus of hoarse yells arose from the deck of our own craft: I saw the officers stand suddenly erect in the boat that was approaching us, and I heard loud cries and curses from the raider. Then I turned my attention to my own business. Most of the men on the submarine's deck were standing in paralyzed fascination, staring at the torpedo.

Bradley happened to be looking toward the conning-tower and saw me. I sprang on deck and ran toward him. "Quick!" I whispered.

"While they are stunned, we must overcome them."A German was standing near Bradley--just in front of him.

The Englishman struck the fellow a frantic blow upon the neck and at the same time snatched his pistol from its holster.
