And it was there they found him, talking to Jerry’s mother, who was entertaining the little scientist, meanwhile wondering what was keeping the boys.

“Well, how does it feel to be a hero?” asked Ned, as he greeted the professor.

“A hero?” murmured Mr. Snodgrass, wonderingly.

“Yes. Didn’t he tell you, Mother?” inquired Jerry. “He stopped the team that was running away with the fire engine and——”

“And you never mentioned it, Professor!” exclaimed Mrs. Hopkins.

“Too modest!” murmured Jerry.

“Really, I never gave it a thought,” said the visitor. “In fact, I didn’t notice anything about the vehicle in question. I only saw some horses coming down the road, and I didn’t want them to step on a colony of bugs I wished to investigate. That is all there was to it. But did the fire amount to anything, boys?”

“Yes, it was some fire,” answered Bob. “And, what’s more, Jerry and Ned did a bit of hero work themselves,” and he related the incident of the rescue of the Frenchman.

“Oh, it wasn’t anything!” declared Jerry, as he saw his mother looking proudly at him. “Bob was in it, too. If he hadn’t been so fat he couldn’t have kept the ladder from slipping.”

“That’s right!” chimed in Ned. “I guess we can all congratulate ourselves.”
