“Oh, I don’t mind a little bite like this,” said Professor Snodgrass, putting some peroxide on the punctures. “I must have another beetle.”

“And he got it, too!” said Jerry, telling about the incident afterward, “or rather, the beetle got him again, on another finger.”

The professor was enthusiastic over his specimens, even though the bites poisoned him so that his fingers swelled up, and he could not write for a week. But he said it was worth all the pain.

“Well, shall we take in the fair?” asked Jerry of his chums the next day after lunch.

“Sure thing!” cried Ned. “I want to see if they have anything new in aeroplanes.”

“They’ll have to go some to beat the motor ship we had,” observed Bob. “But we’ll have some fun, anyhow. Let’s make up a crowd and go in the machine.”

This was agreed to, and with Tom Bacon, George Fitch, Ted Newton and Chet Randell, the boys set off for Fairview that afternoon, “cutting” some lectures in order to make the trip.

The fair grounds were a lively place, for tents and booths had been put up over night, and, gaily decorated with flags and bunting, made a pleasing picture that bright October day.

“There’s the aeroplane over there!” cried Ned, as they went to the parking place with their automobile.

“Two of ’em!” added Bob. “They’re just the ordinary type, though. Nothing like what we had.”
