President were speaking
through a megaphone in addition to the radio and by the use of the
megaphone the voice was carried to people in the audience a third of a
mile away. By the time those persons heard it, the man in the moon could
have heard it too--that is," he added, with a laugh, "supposing there
really were a man in the moon and that he had a radio receiving set."

"It surely sounds like fairyland," murmured Joe.

"Radio is the fairyland of science," replied Mr. Preston, with
enthusiasm, "in the sense that it is full of wonder and romance. But
there the similarity ceases. Fairyland is a creation of the fancy or the
imagination. Radio is based upon the solid rock of scientific truth. Its
principles are as certain as those of mathematics. Its problems can be
demonstrated as exactly as that two and two make four. But it's full of
what seem to be miracles until they are shown to be facts. And there's
scarcely a day that passes without a new one of these 'miracles' coming
to light."

He had reached his corner by this time, and with a pleasant wave of his

"Oh, there are plenty of other pieces," said Jimmy, as he picked one up
and started for Herb.

Herb started to run, but slipped and fell on the icy sidewalk.

"You know what the Good Book says," chaffed Joe. "The wicked stand on
slippery places."

"Yes, I see they do," replied Herb, as quick as a flash, looking up at

The laugh was on Joe, and Herb felt so good over the retort that he did
not mind the fall, though it had jarred him considerably. He scrambled
to his feet and brushed off his clothes, while Jimmy, feeling that his
comrade had been punished enough, magnanimously threw away the piece of
ice that was to have been the instrument of his vengeance.
