"Oh, no," said Susie. "How could I? I've never been up in a balloon."
"I know," was the reply, "but have you never seen anything near the ground that looked at all like a cloud?"
"I don't remember," said Susie, shaking her head.
"We've seen fogs along the river," said Frank. "They look a little like clouds. You know we see them almost every morning."
"Oh, yes," exclaimed Donald. "Don't you remember that fog we had early last spring? Why, uncle, it was so thick we couldn't see the barn from the house."
"And, uncle," said Susie, "I went out to the barn with father, and in a few minutes there were little drops of water on my hair, and all over my cloak."
"Did it last all day?" asked Uncle Robert.
"Oh, no," said Frank, "only for a little while in the morning. Then it went away and the sun came out."
"How did it go away?" asked Uncle Robert.
"Why," said Donald, "at first it began to get lighter, and we could see things plainer."
