WE have a very high appreciation of the value of a good Sabbath-school library. It seems to me that no form of circulating sound religious reading is superior. The books, however, require to be selected and adapted with the greatest care. This is certainly a difficult matter, but the object to be attained is so great as to reward the effort. Many schools are now flooded with the most vicious, improper books. There is no justifiable excuse for this. Never were there so many good books for children and youth as now. Several hundreds that teach the soundest Christian morals and are true to life, and filled with the soundest evangelical Bible instruction, can now be selected. There is scarcely a shadow of excuse at the present time for admitting even a doubtful book into our Sabbath-school libraries—unless some will accept the plea of ignorance and laziness. Our children's minds should be as sacredly guarded from poisonous books as their bodies from poisonous drugs. There should be a judicious standing committee in every school to select library books, while the pastor should always carefully revise their selection.

The books of the Sabbath-school library must be attractive and interesting, or they will not be read by the young. They must be true to life and fact, or they will prove pernicious. They must be instructive, or they should find no place in the library. They should be adapted to awaken, convict and convert, to nourish in the religious life and morals, and throw light upon all the pathway of everyday practical life, or they will fall short of meeting the great want. They must strictly conform in all things to the Bible standard, or they should never be found in any of our Sabbath-school libraries.

Better have no books than to have unsound ones. Spare no pains to procure an abundance of good, sound, attractive, and useful reading, and we will soon drive away the flood of bad books which is now threatening to destroy our youth. Several copies of superior books should be placed in the library at the same time. Select such as are adapted to all ages and conditions, from the children in the infant-school up to the wide-awake young men and women in our highest adult Bible classes, and to teachers. Let them also cover all stages of religious feeling and want. Books of narrative, history, biography, youthful Christian experience and training, on temperance, good morals, good habits and manners, should all be provided for the thorough religious instruction of our children and youth. The library should also comprise a good teacher's library with good reference Bibles, a Concordance and Dictionary. Then give the books the largest, freest and most active circulation.

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. After the teaching is closed, the lesson reviewed by the superintendent, remarks made, prayer, singing, etc., then the librarian, by a notice from the superintendent, passes down the aisle and hands each teacher his lot of books, and the teacher passes them to each pupil according to the library card, and then the school is dismissed. No scholar opens his library-book or paper in the school. The teachers have no care of the books or their numbers, unless the scholar loses his library-card; in which case his teacher, at the close of the school, accompanies him to the library and obtains for him a new library-card and book. The librarian and his assistant charge and credit all the books while the teachers are teaching. Each class has a column or place in the register. This plan satisfies the scholar, he has his own choice, and never interrupts the teachers or the school for a moment, or diverts the attention of the school, and no time is lost. It works admirably.

The Librarian.—The librarian's office is an important one. He should be one of the most considerate, watchful, careful young men in all the community, for his office gives him much prominence. He should open the library, arrange it in order, distribute hymn and class-books before the school opens, and allow no unauthorized person access to the library. He will become acquainted with the general character of the books, as well as know the scholars, that he may intelligently aid them in their selections. He will, also, ascertain what class of books is most in demand.
