ossible future of radio. Then
the Doctor arose again and said:

"We want to have members of our student body, also, express to you our
interest in this great subject. We are fortunate to have this year a
pupil who, though yet a freshman, has shown an unusual grasp of the
technicalities of radio. I am going to ask Mr. William Brown to explain
briefly some of the methods employed in building, or selecting, a radio
receiving set, such as those he has been engaged in making here at the
school. His associate, Mr. Augustus Grier, who is an artist, in
mechanical matters at least, will aid Mr. Brown at the blackboard."

Bill laid aside his crutch and hobbled forward to the platform, followed
by Gus, whose easy motions were in direct contrast. A round of applause
greeted the boys. This was increased and a burst of laughter added when
Gus took a piece of chalk and with a few quick strokes made what suggested
a broadcasting station, with a rooster shouting "cock-a-doodle-doo" into

CHAPTER VIII

RADIO GALORE

"A good many folks," said Bill, "get scared when they think about radio
construction. The big words come at them all in a bunch like a lot of
bees, and it is to dodge. And when they go to the dictionary they are
lost for sure. Potentiometer, variometer, variocoupler, radio frequency,
amplification, loop aerials, audion and grids--no, I am not saying
these words to show off. They are only a part of radio terminology. And
you've got to get 'em, or you might as well take radio theory and
construction on faith and be satisfied simply to listen in.

"Anybody can commit these words to memory without a dictionary, and
that's where my partner shines. He has heard the big words so much that
he talks them in his sleep, and he ought to know all their meanings, but
the one most his size is 'grid.'"

Here Gus drew a much scared boy, with hair on end and knees knocking
together, surrounded by a lot of the words that Bill had pronounced.
Then Bill, putting his hand to the side of his mouth and leaning toward
his audience as though in confidence, said in a stage whisper:

"He's doing that to show t
