“Oh, no.”

“Why not? The postman does.”

“Yes, I know that,” said little Walter, “but I did it as a s’prise.”

“Oh, a surprise?”

“Yes, s’prise. That’s the first house,” said Walter, pointing around the corner as they reached the next street.

Bob lowered Walter to a hitching-block, and went up the walk leading to the house before which he had halted.

“That’s good,” he said to himself, as he saw the end of an old envelope sticking out from half-way under the door.

“One of the twenty letters, anyway,” added Bob, placing the envelope in his pocket, as he read the address of Miss Simmons upon it.

At the second house he saw no letter lying around the porch. A lady came to the door. She knew Bob.

“I am looking for a letter Miss Simmons’ little nephew left on your door-step,” he said.
