They hurried along, H.D. gawking to all sides, almost trotting as Junior set the pace. At the great double door of an elevator shaft Junior touched the signal button. Big--everything around here was _big_! The elevator could have accommodated several pianos and the pretty red-head operating the lift had to look down at H.D. She winked and made a laughing remark. "She says you're cute." H.D. did not know whether to be pleased or offended and before he could decide the acceleration took his breath away. They went up, up, a ridiculous distance, and at last he stepped out into another corridor. _Corridor!_ The floor must have been forty yards across and most of it was moving, a series of horizontal escalators with three speeds in each direction, adjacent strips moving at different speeds. * * * * * While H.D. stared, Junior and Garry Jones had stepped aboard the nearest strip and were moving away. Now Jones came trotting back, making little headway against the conveyor's motion. He had to chuckle. _In my country, said the queen, you have to run like the devil to stay in the same place._ "Come on, Mr. Haworth," Garry called. H.D. waited for the next opening in the rail to oppose him, took hold and stepped on. When he had come up, Garry explained, "This is Chicago--this building--this is the whole city, the business part, that is. This is one of the transport levels." "Hmm." The place didn't look right--too bare, too empty. "Where are the stores? Where are the signs? Where are the people?" "Stores? Oh, this is just a garage. Working day's over. Just about everybody's gone home." "Garage?" "Sure, for flyers--remember? Here we are." The door Junior unlocked let them into a space sufficiently garage-like in its bareness, but the thirty feet of gold-and-crystal grace it sheltered was a thing of beauty, enough to warm the cockles of any limousine-lover's heart. As H.D. gave himself up to the upholstery's caress he felt his old confidence return. [Illustration: The thirty feet of gold-and-crystal grace the garage held was a thing of beauty.] The wall rolled away as Junior made some unperceived signal. With the slightest of vibration the flyer wafted out into the shadowed evening. As the wingless craft emerged into space H.D.'s hands instinctively tightened their grip on the arms of his chair. Then he relaxed with a smile. He looked around with appreciation, ready to accept each new thrill with easy complacency. When the mounting flyer finally cleared the shadow of that Everest of a building they must have been six thousand feet up. In the western distance the dipping sun shed its fire on a doll's garden of patched green, with here and there a spot of cheerful early autumn color. _Charming_, he thought patronizingly, _charming!_ "Let's go down closer and have a good look at those suburbs," he exclaimed on sudden impulse.
