“My father—wants a doctor?” faltered Ned. “What for?”

“Because he was slightly hurt in the same accident when the wheel came off the auto,” gently explained the professor. “It isn’t anything serious, though. He’s at the hotel in town and your father is with him, Bob. That’s what I came to tell you. But there is no need to worry.”

“Well, of all the——” began Ned.

“What in the world——” murmured Bob.

“Don’t stop to talk!” cried Jerry. “Let’s get a machine, hunt up a doctor, and go to the hotel at once. What does it all mean, Professor Snodgrass? No! don’t stop to tell me. You can explain later. Lively, fellows! Come on!”

“Anything I can do?” asked Jim. “Say the word!”

“You might get a machine for us,” suggested Jerry.

“I’ll get Charlie Moore’s,” offered Jim. “He isn’t using it.”

Out he rushed, leaving Ned, Bob and Jerry to get ready, for they had taken off coats, ties and collars on reaching their rooms. They dressed hurriedly, Jerry meanwhile asking Professor Snodgrass if the scientist himself were not in need of medical treatment.
