The others were of the same opinion, and they listened for some repetition of the voice in the hope that its possessor might drop some clue to his identity, but although they missed most of the concert by trying to catch the talk of the object of their interest, they heard no further word of him that evening nor for many more to come.
The next morning but one when Bob joined his companions it was plain to see that he was bursting with news.
"Say, fellows," was his salutation, "did any of you read in the morning papers of the big Radio Show that is opening up in New York City?"
They had to confess that they were innocent of any such knowledge.
"It opens to-morrow," went on Bob. "They say it's going to be one of the biggest things that ever happened. A regular rip-roaring, honest-to-goodness show. They'll have all the latest improvements in radio sets and all kinds of inventions and lectures by men who know all about it, and automobiles that run by wireless without any drivers—"
"For the love of Pete," interrupted Joe, "go a little easy and let us take it in a little at a time. Any one would think you were the barker at a sideshow. Where is this wonderful thing to be?"
"On the roof of one of the big New York hotels," answered Bob. "I forget the name just now, but it's one of the biggest in the city. What do you say, fellows, to taking it in? We ought to get all sorts of ideas that will help us in making our sets."
"Count me in," replied Joe promptly. "That is, if my folks will let me go, and I think they will."
"Don't leave out little Jimmy," remarked that individual.
"Me too," added Herb. "That is, if dad will see it the same way
I do."
