But as Mr. Bobbsey took a look he laughed and said:

"This is the time you were fooled, little fireman! That isn't a fire engine at all. That's some sort of engine they use for fixing the streets. They have to work on the streets here after dark, as there are too many automobiles and wagons on them in the day time. There isn't any fire, Freddie!"

"Maybe there'll be a fire to-morrow," returned Freddie, rather hopefully, though of course he did not really want any one's house to be burned.

"Well, there isn't a fire to-night—at least not around here," said
Mr. Bobbsey. "Now we can go back to bed."

Bert nor Nan nor Flossie had been awakened by the noise which roused Freddie. And really it had sounded like a fire engine. A gang of men with a big steam roller was at work in the street just below the little Bobbsey twins' window. And smoke and sparks were spouting from the boiler of the steam roller just as they often spouted from a fire engine.

Freddie slept soundly after that little excitement, and the Bobbsey family did not get up very early the next morning, as they were all tired from their travel.

"Do we go on to Lumberville to-day, Daddy?" asked Bert after breakfast in the hotel.

"Yes, we start this evening and travel all night again," his father answered. "In the morning, or rather, about noon to-morrow, we ought to be at the lumber tract."

"And shall I see 'em cut down trees?" asked Freddie.

"They don't do much cutting down of trees in the summer," said Mr. Bobbsey. "Winter is the time for that. Still there may be some cutting going on, and I hope you can see it."
