like that."

"What are you fellows chinning about?" asked Jimmy Plummer, one of
their schoolmates, who came up to them at that moment. "You seem all
worked up about something."

"It's about that talk Dr. Dale is going to give us to-night on the
wireless telephone," answered Bob, as he edged over a little to give
Jimmy room to walk beside them. "You're going, aren't you? The doctor
said he wanted all the boys to come who could."

"Do you suppose there'll be any eats?" asked Jimmy, who was round
and fat, and who went by the nickname of "Doughnuts" among his mates
because of his fondness for that special delicacy.

"Always thinking of that precious stomach of yours!" laughed Bob.
"Jimmy, I'm ashamed of you. You're getting so fat now that pretty
soon you won't have to walk to school. You can just roll there like
a barrel."

"You string beans are only jealous because I get more fun out of
eating than you do," declared Jimmy, with a grin. "But eats or no
eats, I'm going to hear what the doctor has to say. I got a letter
the other day from a cousin of mine out in Michigan, and he told me
all about a set that he'd made and put up himself. Said he was just
crazy about it. Wanted me to go into it so that he and I might talk
together. Of course, though, I guess he was just kidding me about
that. Michigan's a long way off, and it takes more than a day to
get there on a train."
