Just then Danny Rugg came into the post office.
"A party; eh?" he sneered. "I'm coming to it, I am; and I'm going to have two plates of ice cream."
"You are not!" cried Freddie. "Our mamma wouldn't let a boy like you come to our party."
"'Specially not after what you did—telling us to play in the water," added Freddie. "You can't come!"
"Yes, I can," insisted Danny, just to tease the children.
For a moment Flossie and Freddie almost believed him, he seemed so much in earnest about it.
"You can't come—you haven't any invitation," said Flossie, suddenly.
"I'll take one of those you put in the box," went on the mean boy.
"He won't dare—will he?" and Freddie appealed to the mail clerk.
"I should say not!" said the man at the stamp window. "If he does
Uncle Sam will be after him."
