"That's big stuff," I replied at once, "if you can substantiate it." "I think you will believe me when I have finished," he replied quietly. "I have risked my life more than once to get at the facts. My father, Sir Thomas, was a missionary in China. I was brought up to speak the Chinese language as well as English. I am one of the very few Europeans who do so fluently. Moreover, I kept it up till I was sixteen and came to England, and I have never forgotten it. You have heard, I suppose, that there's a gang of Chinese coolies at work on the towers, and some of the Trade Unions have been making themselves nasty about it, and the American labor?" "Yes, there was some agitation." "In addition to these coolies, there are many Chinese officials of a much higher class, people who will remain when the towers are finished, as they will be in an incredibly short space of time, for the work is being carried on both by day and night. Speed, speed, speed! is the order, and nothing in the world is allowed to stand in the way of it." "You interest me very much. Please continue." "Speaking Chinese as I do, being perfectly familiar with Chinese dress and customs, it has not been difficult for me to disguise myself--blacken my hair, assume a yellow complexion and so forth. "By this means I have penetrated to the very heart of the workings at night, and," he blushed faintly, "I have listened to conversations of an extraordinary character, lying on the roof of a certain office building for hours. Details you shall have, and in plenty, but here is the sum of my discoveries. There is no syndicate. There never was. The work, upon which millions have been spent, has been, from the very first, designed and originated by one individual, with the specialized help of the most famous engineers of America." "And his motive?" I asked, and I don't mind saying that I was almost trembling with excitement. "The dream of a genius, or the whim of a madman," Rolston answered in a grave voice. "The world will call it one or the other without a doubt. At any rate it's the product of a colossal imagination. For myself, I am dead certain that there's some deeper and stranger motive beneath it all, but that can rest for the present. Sir Thomas, between those three great towers, two thousand feet up in the air, will very shortly come into being a fantastic pleasure city like a dream of the Arabian Nights! It will be unique in the history of the world, and already the preparations are so far advanced that it will be completed with extraordinary rapidity." "A pleasure city!" I gasped. "A Pleasure City in the Clouds!" "On two stages right up at the very summit, suspended by a system of cantilevers of the most intricate modern construction and of toughened steel. I understand that a triangle measuring in all four acres will support a marvelous series of palaces, a Lhassa of the air!" "Why Lhassa, Mr. Rolston?"
