_Managing the Library._--In a great many Sabbath-schools the manner of distributing the books is a very bad one, and in consequence of this some schools have improperly discarded the library altogether. The great difficulty has arisen from the fact that the librarian has been allowed to be on the floor and have access to and interrupt the teachers during the teaching hour. This should never be allowed. An interruption to the teacher while applying divine truth may peril souls for ever, and therefore should be carefully guarded. The only access to the teachers which the librarian ought to be allowed during school hours is to simply hand them the books, just at the close of school. There are several good systems for distributing the books that conform to this idea and protect the teachers. I would never ask the teachers to write the scholars' names or numbers for books, or do the work of selection, during the school hours. In the management of the library, what is called "The Check System" is considered one of the best. We cannot describe the various good plans, but I will detail one which seems to me to be more simple and to obviate more difficulties than any other that I am acquainted with. It first provides a carefully-printed numerical catalogue of all the books, with the number of pages. Give to each scholar one of these catalogues, and replace it when lost. If the school is a small district-school, a written catalogue will answer the purpose equally well. Then a "Library Card," four inches by two-and-a-half inches, is provided for each scholar on the first of each month. On this is written or printed--"Library Card," "Class No. 6," "John Smith." Each scholar takes his "Library Card" and catalogue home, and there, with aid from his parents or a friend, he selects from ten to fifteen books, either of which he will be satisfied with during the next four weeks. The "Library Card" is then placed in his book, and kept there as a marker, and is returned to the librarian on the next Sabbath with the book. Each scholar hands his book, with the card in it, as he enters the room, to the librarian, who is always to be found at the opening of the school at the outer door of the school-room, with a large basket ready to receive all the books from the pupils. When the school is opened the librarian carries these books to the library and assorts them, as he ascertains from each book-mark to whom and what class and name the book belongs. The book is then credited as returned, and the new one charged. If any scholar wants one book particularly that is on his list, he _underscores_ it, and if it is in the library, it is given to him and charged. If any scholar is late, and the librarian has gone to the library, he loses his exchange of books on that Sabbath. The librarian keeps the account of all library-books, and charges them all to each name and class according to the book-mark, and credits them when returned, and the teacher has no care of it.
