court of gleaming amber crystal. Something like a taxi slid up, with
irridescent planes, and he was bundled into it, whirled away again.

Down broad, gleaming avenues they passed, where similar traffic flowed
densely, but under marvelous control. Towering skyscrapers loomed to
right and left. Tier on tier of upper and lower boulevards revealed
themselves, all crowded with automotive and pedestrian activity.

At length a stupendous concourse was reached. Thousands of these taxis
and similar vehicles were parked along its broad flanks, while literal
swarms of diminutive individuals circulated to and fro.

Assisted from the vehicle that had brought him to this obvious center

of jade-green stone that towered a full hundred, stories above the
street level. There he was escorted into another of those
projectilelike elevators, shot up, up--till at length it came to rest.
The door opened and he was led out into a small lobby of the same

English. "It is indeed a pleasure to welcome you to my humble
quarters. Pray enter and make yourself comfortable."

Whereupon he ushered him into a dazzling apartment that was one vast
mosaic of precious gems, indicated a richly carved chair, into which
the young scientist dropped wonderingly.

"Now then, Professor," continued the mighty little dwarf, when he was
seated in a chair even more sumptuous, "suppose we have a friendly
little discussion. I have been much interested in your experiments on
heat radiation. What you demonstrated this morning, in particular, wa
