"They're going to put the big balloon up to-day," said Harry.
"They are if the wind doesn't blow too much," Bert agreed. "And I'm afraid it's blowing too hard. Do you think the wind is blowing too much for them to send the big balloon up?" he anxiously asked his father.
Mr. Bobbsey looked at the sky.
"To my mind," he said, "I think there is going to be a storm. I'm afraid the wind will keep on blowing harder all day. Of course I don't know how strong a wind it takes to keep a balloon man from going up, but I should say there would be danger in going up to-day."
"Oh, dear!" exclaimed Bert. "I wanted to see the man go up in the balloon!"
"So did I!" added Harry. "But maybe the wind will die out."
However, it did not, and it was still blowing rather hard when the fair grounds were reached.
"Never mind," said Mrs. Bobbsey, when she saw how disappointed Harry and Bert seemed to feel. "If the balloon doesn't go up to-day it will to-morrow, and we can come again. There are plenty of other things to look at besides balloons."
"I'd like to go to see some of the big vegetables and the fruits, and look at the patchwork quilts and the lace," said Nan.
"Very well," agreed her father. "We'll go there first, and maybe by that time the wind will have died down. But I hardly think so."
