"None at all," said Hugh. "This one is for your father."

Frank grew red in the face, "If this is a joke I swear you'll be sorry for it," he exclaimed hotly.

"It's no joke at all," said Hugh. "We found this letter lying here under the mat. I was just going to hand it to you."

Frank took the letter from Hugh and looked at it suspiciously. Then he turned it over and looked at the back of it. Suddenly he turned pale.

Bob and Hugh, watching him closely, noticed this fact, and Bob, suddenly plucking up courage, determined to speak of it.

"What does that alligator mean, Frank?" he asked.

The color rushed back into Frank's face. He looked as though he were going to run. He swallowed hard two or three times, choked, and then swallowed again. "I don't know," he blurted out finally, and stepping inside slammed the door shut in the faces of the two boys.

Hugh looked at Bob and smiled. "Frank was certainly glad to see us, wasn't he?" he said sarcastically.

"I should say so," Bob agreed. "Let's go home."

They went down the steps and walked slowly in the direction of the
Cook home.
