“I can’t say,” replied the doctor, a merry twinkle in his eye. “That is, with modesty. For Will is my partner.”

“A doctor!”

“No; a mushroom grower.”

Mr. Williams seemed puzzled, but waited to hear more.

“You’d better see the boy yourself,” continued the doctor. “He’s proud, you’ll find; and he’s very poor.”
