"How did those children get in there?" asked one of the balloon men.

"They must have crawled in the basket when we weren't looking," answered Mr. Bobbsey.

"Is there any way of saving my little children?" cried Mrs. Bobbsey.

"Now don't you worry," said the balloon man kindly. "They'll be all right if they stay in the basket. The balloon hasn't all its gas in, and it won't blow very far. It will soon come down to the ground."

"But won't they be killed?"

"No, a balloon comes down very gently when the gas gives out." said the man. "It's almost like a parachute. Your children will come down like feathers. We'll get up a searching party and go after them." He knew there was great danger but he did not want to add to Mrs. Bobbsey's fears.

"Oh, yes! Do something!" cried Mrs. Bobbsey. "We must save them!"

While down below there was all excitement and while a searching party was getting ready to start out to rescue Flossie and Freddie, the two little children themselves were safe enough in the balloon basket. That is they were safe for the time being, for they could not fall unless they climbed over the side of the basket, and they would hardly do this. They were also safe from banging into anything, for they were now high in the air, well above all trees and buildings, and there were no other balloons or any aeroplanes in sight.

At the fair grounds was an aeroplane, but it had not gone up yet, and could not, for the engine was broken, and the man had to mend it before he could make a flight. So as long as Flossie and Freddie remained in the basket they were safe.

They did not even feel the wind blow, for as they were being carried right along in the gale, being a part of it, so to speak, they did not feel it as they had when standing on the ground.
