"Received from Solon Talbot the sum of One Hundred Dollars, being the full amount due me from the estate of my late father, Elisha Doane, of which he is the administrator."
Mr. Talbot placed the paper on the table, and pointing to a black line below the writing, said, "Sign here."
"Let me see the paper, mother," said Mark.
He read it carefully.
"I advise you not to sign it," he added, looking up.
"What do you mean?" exclaimed Solon Talbot angrily.
"I mean," returned Mark firmly, "that mother has no means of knowing that a hundred dollars is all that she is entitled to from grandfather's estate."
"Didn't I tell you it was?" demanded Talbot frowning.
"Uncle Solon," said Mark calmly, "I am only a boy, but I know that one can't be too careful in business matters."
