“All aboard!” called Tom Case, as he prepared to send the carriage on its return trip. Mrs. Bobbsey and Flossie and Freddie took their places.

There was a rattle and a rumble, and back they shot, the twins shouting in glee and kicking aside the piles of sawdust. Thus they had great fun at the sawmill, and they did not want to come away when the noon whistle blew and it was time for lunch. For there was a steam engine in Cedar Camp, as well as the turbine wheel, and this steam engine had a whistle which the engineer blew to tell the men to stop for dinner.

After dinner Mrs. Bobbsey went to lie down, and after cautioning Flossie and Freddie not to go near the sawmill without her, she left the smaller twins to amuse themselves near the cabin. Their father was out with some of his men looking after Christmas trees, and as Bert and Nan had gone nutting, Flossie and Freddie looked about to find some amusement of their own.

“Let’s play sawmill!” proposed Freddie, as he and Flossie wandered down near Pine Brook, where it ran over the dam, making a waterfall.

“All right,” agreed the little girl. “But what’ll we have for a saw?”

Freddie looked around and noticed a wheelbarrow not far off.

“That’ll do,” he said. “We’ll turn it downside up, and I’ll turn the wheel for a saw and you can hold sticks against it and make believe they’re being sawed up.”

“All right,” agreed Flossie. “That’ll make a fine saw.”

They went over to the wheelbarrow, and then a new idea came to Freddie.

“Oh, Flossie!” he cried, “you sit in it and I’ll wheel you down to the edge of the brook. We’ll have our sawmill there, and make believe to snake logs out of the water like Mr. Case did.”
