The air ship trembled. It was a sensation never experienced before. The vibrations seemed to pass through the innermost fibers of my being. I felt that we were being lifted in the air, and then that we were slowly floating out at the open end of the barn.

There was a shout and a curse and a call to arms. Noiseless as our movements had been, the men were aroused, and in an instant a score of voices were calling and yelling in every direction:

"Stop thief! Surround the barn! Where are they?"

A hideous medley of curses, groans, and sounds of fighting rose through the darkness from every quarter of the field; but the air ship was far above, and hidden from eight in the dense gloom of the morning fog.

"Let them fight it out among themselves," said Torrence, drawing a long sigh of relief; "we shall never see them again!"

We rose steadily and slowly for several minutes, Torrence saying it would be necessary to be well above the houses, as we were going to pass directly over London and must take no risk of a collision in the darkness. Presently I could feel that we were sweeping ahead. The movement was perfect, and as we sped rapidly forward through the dense atmosphere, catching an occasional glint of a street lamp below, all sense of fear departed. The trembling had ceased; and I felt as though we were floating rapidly away on the breast of a cloud, or upon, the back of some monstrous bird; only here there was no effort. It was the only element comprehended. I could imagine nothing more sublime, more exhilarating. It was the absolutely finished poetry of flight. Beyond this, there was a feeling of safety far surpassing that of earthly locomotion, possibly due to the knowledge that we were lifted clear above all obstacles; that no uncertain switch, or ill-timed train could affect us. On we swept, in an ecstasy of rapture, realizing neither our speed nor place, engrossed only with the novelty of our situation, and watching the coming dawn.

Suddenly a great, dazzling object not twenty yards away flashed past us.

"Great God!" exclaimed Torrence, rising, "I thought I was too high for that."

"What was it?" I asked in amazement.

"The cross on top of St. Paul's!"
