Through the underbrush, between trees, and in the dripping rain and swirling fog, the searching party tramped on. Suddenly one of the men gave a cry.
"I see something!" he shouted.
"Is it my children?" Mrs. Bobbsey asked, her voice trembling with eagerness.
"No, I think it's the balloon," was the answer.
And the balloon it was. Draped over bushes and trees was the big gas bag, now almost emptied of the vapor that had lifted it and carried it away from the fair grounds with Flossie and Freddie in the basket.
"Oh, but where are my little ones—my Bobbsey twins?" cried the mother.
"They must be somewhere around here," said Captain Craig.
And then, thrilling the hearts of all, came two young voices, calling:
"Daddy! Mother! Here we are! Oh, we're so glad you came! Here we are!"
Out of the woods rushed Flossie and Freddie, to be caught up in the arms of Mother and Daddy Bobbsey.
