"I'm takin' a letter to Brooklyn for the doctor."
"Are you?"
"Yes," said Sam; adding unluckily, "There's money in it."
"Is there?" said Jim, pricking up his ears. "How do you know? Let's see the letter."
Sam took the letter from his inside coat-pocket, and passed it to Jim.
The latter held it up to the light, and tried to look inside. Fortune favored his efforts. The envelope was imperfectly fastened, and came open.
"There, Jim," said Sam, "now see what you've done."
"Let's look inside, and see how much money there is," suggested Jim.
Sam hesitated.
