It had a number of polished knobs and
dials and several groups of wires that seemed to lead in or out of
the instrument. Connected with it was a horn such as was common enough
in the early days of the phonograph. There were also several pairs
of what looked like telephone ear pieces lying on the table.
They eyed it with intense curiosity, not unmixed with awe. They had
already heard and read enough of the wireless telephone to realize
that it was one of the greatest marvels of modern times. It seemed
almost like something magical, something which, like the lamp of
Aladdin, could summon genii who would be obedient to the call.

rose and took up his stand near the table.
"Now, boys," he said, "I've asked you to come here to-night so that we
can talk together and get a little better idea of some of the wonders
of the world we are living in. One of those wonders and perhaps the
most wonderful of all is the wireless telephone," and here he laid
his hand on the box beside him. "Most of you have heard of it and want
to learn more about it. I'm going to try to explain it to you just
as simply as I possibly can. And I'm not going to do all the talking
either, for I want you to feel free to ask any questions you like.
And before I do any talking worth mentioning, I'm going to give you
a little idea of what the wireless telephone can do.
