“A runaway? No, my dear boy, I did not. I heard some yelling, and I saw the fire engine coming my way. But the reason I stopped it was because a little while ago I saw, just beyond, in the road, a most curious bug of a kind that only appears early in April in this locality. I was eager to get it, and I was afraid, if the horses and engine trampled the roadway, that I would lose the exceedingly rare specimen. That’s why I stopped the animals. I had no idea that it was a runaway, but I’m glad if I have been of any service. If you’ll excuse me, now, I’ll go and look for that bug,” and, as though it was his custom every evening after supper to stop a runaway fire engine in danger of plunging into the river, Professor Snodgrass turned aside and began searching in the dust for the bug he wanted. Off to one side, in the grass where he had carefully placed it before stepping out to stop the horses, was the collecting box the boys knew so well. “Isn’t he the limit?” cried Jerry. “Same old professor. Hasn’t changed a bit,” observed Bob. “Well, considering it was only about three weeks ago that we left him at Boxwood Hall, there hasn’t been much time for change,” returned Ned, with a laugh. “But say, fellows, what’s to be done?” he went on. “That fire’s growing worse, and it looks as though one of these horses was out of business.” “He is,” said Hank Tedder, the engineer. “His leg’s broke. He’ll never pull another engine. And how I’m going to get this steamer to the fire--first alarm it’s ever responded to--I don’t know.” The boys did not either--that is Ned and Bob did not. But Jerry did. He was always resourceful. “Unhitch the horses!” he cried to Hank. “Push the engine back so it clears, and we’ll tow it to the fire with our auto.” “Can you?” asked Ned. “Sure. We’ve got plenty of power, and it’s a level road from here on. Downhill, if anything. You can ride on the seat, Hank, and put on the brake when it’s needed. Come on, boys!” “All right. And it can’t be any too soon!” murmured Bob, as he looked at the reddening sky. “They may send the other engine,” said Jake Todger, another fireman who came up in some one’s automobile just then. He worked to free the injured horse while the boys unharnessed the other one. Professor Snodgrass seemed to have forgotten about everything but the bug he was looking for in the dust of the road, under the electric light. With straps from the harness, and a strong towline carried on the auto, the machine was soon hitched to the steamer, and then Jerry once more took his position at the steering wheel. “Going to leave the professor here?” asked Bob, as Hank climbed to the driver’s seat of the steamer, while Jake got on behind. “Guess we’ll have to,” replied Ned. “I didn’t know he was in town. He must have just arrived, and probably he has come to pay one of us a visit. He’ll look us up later--when he’s found that bug. Best to leave him alone.”
