We changed our lift at each stage; and I could have wished that it was day or the night was finer, for the experience is wonderful when one undergoes it for the first time.

"We shall ascend by one of the small rapid lifts built for four or five persons only, and not the large and more cumbrous machines. Even so, you must remember, Doctor"—he chuckled as he called me that—"we have nearly half a mile to go."

On and on we went, amid this lifeless forest of steel with its smooth concrete and shining electric-lamps, until at last we approached a small, illuminated pavilion, where two silent celestials awaited us. We stepped into the lift, the door was closed, a bell rang and we began to move upwards. I sat down on a plush-covered seat and didn't attempt to look out of the frosted windows on either side until at length, after what seemed an interminable time, we stopped with a little jerk. Pu-Yi opened the door and led me down on to a platform.

"We are now," he said, "on the first stage—just fifty feet higher than the golden cross on the top of Saint Paul's. If you will come up this slant—see! here's the next lift."

I followed him along a steel platform for some twenty or thirty yards, the wind whistling all around. On looking to the right I saw nothing but a black void, at the bottom of which, far, far below, was the yellow glow of Richmond town. On looking to the left I stopped for a moment and stared, unable to believe my eyes. As I live, there was an immense lake there, surrounded by rushes that sang and swished in the wind, with a boat-house, and a little landing-stage!

Then, with a clang of wings and a chorus of shrill quacks, a gaggle of wild duck got up and sped away into the dark.

"Yes," said Pu-Yi, "that's the lake. There are many variety of water fowl fed there, who make it their home. On a quiet afternoon, walking round the margin, or in a canoe, one can feel ten thousand miles away from London. But that's nothing to what you will see if circumstances permit."

I have but a dim recollection of the second stage, which was only a stage in the particular tower we were mounting, and did not extend between the three as the lower and two upper ones did, forming the immense plateaus of which the lake was one and the City in the clouds itself another.

It was when we had slowed down, and even in the dark lift, that I began to have a curious sensation of an immense immeasurable height, and Pu-Yi gave me a warning look as who would say, "Now, get ready, the adventure really begins."

We stopped, the door slid back and immediately we were in a blaze of light. We were no longer out of doors. The lift had come up through the floor of a large room. It was divided into two portions by polished steel bars extending from ceiling to floor. A cat could not have squeezed through. On our side, the lift side, the floor was covered with matting but there was no furniture at all. Beyond the bars were a Turkey carpet, several armchairs, a mahogany table with bottles, siphons, newspapers, and a large, automatic pistol. An electric fire burned cheerily in one corner and at right angles to it was a couch. Upon this couch, purple-faced and snoring like a bull, lay Mulligan, huge, relaxed, helpless.
