There came a shift in the wind, and to the ears of the boys was borne this cry:

"The lumber yard's on fire! Hurry!"

"The lumber yard!" exclaimed Captain Bert. "If that gets going we can't do anything to stop it!"

"We've got to try," declared Cole.

"Of course," answered Bert, as if any one doubted it. "Come on!"

They increased their pace, and as they neared the end of the long street, they were joined by several of their comrades, who had rushed from their houses half-dressed.

"Where's the fire?" called Bob Fenton, who was hardly awake yet.

"Bergman's lumber yard, I heard some one yell," answered Bert. "And this wind blowing right across the lake toward it!"

The lumber yard of Perrett Bergman was located on the edge of the lake, where boats could easily unload their cargo of timber. It was quite a large yard, and was one of the principal industries of Lakeville. As Bert had said, the wind was blowing right across the lake. The breeze was a stiff one, and if it was sending the flames in among the pile of dried and seasoned boards the fire was likely to be a furious one.

But the boys did not falter. They dragged their rumbling engine as fast as they could, the bell clanging loudly as Cole pulled the cord attached to it. The little company was constantly being increased in numbers. Many of the young firemen, however, had proceeded directly to the scene of the conflagration.
