Suppose you loan a book to a friend, would you not consider it his imperative duty to take the best of care of it, as though it were his own, and return it in as good condition as it was when taken? Certainly you would. Then the same duty devolves upon you, as a member of the Sunday school. The school lends you books, and expects you to take good care of them, and return them early. This is no trifling duty. If you have a right to be negligent, every other scholar must have the same right, and the Library would be speedily ruined. Thus your negligence greatly wrongs others. Therefore, children, take care of your books.
