"Remove your clothing," said the mate, as he seized a sponge and soap and began washing the blackened oil from the hands and face of the unconscious Admiral. "We must dress him in your uniform. The Commander of the Lock has orders to take you off the vessel. We must pass the Admiral off for you. He will never be recognized. The Commander has never seen you." Obeying, without fully comprehending, I helped to quickly dress the unconscious man in my own clothing. We had barely finished when we heard voices outside. "Quick, under the bunk," whispered the mate. As I obediently crawled into the hiding place, the mate kicked in after me the remainder of the oiler's clothing which I had been trying to put on and pulled the disarranged bedding half off the bunk the better to hide me. Then he opened the door and several men entered. "I had to drug him," said Grauble's voice, "because he was so violent with fear when I had him manacled that I thought he might attempt to beat out his brains." "Let me see his papers," said a strange voice. After a brief interval the same voice spoke again--"These are identical with the description given by His Majesty's secretary. There can be no doubt that this is the man they want, but I do not see how an enemy spy could ever pass for a German, even if he had the clothing and identification. He does not even look like the description in the folder. The chemists must be very stupid to have accepted him as one of them." "It is strange," replied the voice of Capt. Grauble, "but this man was very clever." "It is only that most men are very dull," replied the other voice. "Now I should have suspected at once that the man was not a German. But he shall answer for his cleverness. Let him be removed at once. We have word from the vessel outside that they are short of oxygen, and you must be locked out and clear the passage." With a shuffling of many feet the form of the third bearer of Karl Armstadt's pedigree was carried from the cabin, and the door was kicked shut. I was still lying cramped in my hiding place when I felt the vessel moving again. Then a sailor came, bringing a case from which I took fresh clothing. As I was dressing I felt my ear drums pain from the increased air pressure, and I heard, as from a great distance, the roar of the water being let into the lock. From the quiet swaying of the floor beneath me I soon sensed that we were afloat. I waited in the cabin until I felt the quiver of motors, now distinguished by the lesser throb and smoother running, from the drive on the wheeled trucks through the tunnel. I opened the cabin door and went out. Grauble was at the instrument board. The mate stood aft among the motor controls; all men were at their posts, for we were navigating the difficult subterranean passage that led to the open sea.
