A word must be said about the co-operation of the Sunday-school and that other great modern agency for work with the youth, the young people's religious society. Whatever is said will be as true of the Epworth Leagues, Baptist Unions, and other denominational organizations as of the Christian Endeavor societies; but since the latter, like the Sunday-schools, are found in all denominations, and since my own especial work lies among them, it will be quite appropriate in this connection, as well as less confusing, to use only the one name, Christian Endeavor.

Though of ages so unequal, "S. S." and "C. E." are sisters. Both are international and interdenominational. Both apply the principle of age classification to religious work. Both are strongly evangelical, and earnest seekers of souls. Both are held in strictest subordination to the church. And both are Bible lovers; for the Christian Endeavor pledge requires daily reading of the Bible, and the weekly prayer-meeting topic calls out no slight amount of Bible study. Moreover, this topic is usually in line with the week's Sunday-school lesson,—not the same as the latter, but suggested by it. The two agencies are at work in different fields. The one puts in, the other draws out. The one studies, the other practices. The Christian Endeavor society affords an excellent test for the Sunday-school, and is its complement. Whatever helps the one aids the other, and the two should labor hand in hand.

There are even some things that the Sunday-school might learn from its little sister. The principle of the pledge has proved attractive and powerful in the Christian Endeavor society. Why not adopt it in the Sunday-school, asking the scholars for voluntary vows that they will attend regularly and will spend fifteen minutes a day in studying their lessons? The monthly consecration meeting maintains wonderfully the spirituality, zeal, and discipline of the Christian Endeavor society. Why not a monthly consecration and experience meeting of Sunday-school teachers? Three or four Christian Endeavor societies cannot exist in the same town without forming a local union for mutual encouragement and consultation. Sunday-schools have their county conventions, but why not also this beautiful interdenominational fellowship among the Sunday-schools of every community? A large part of the remarkable success of Christian Endeavor is due to its being a work of the young people for themselves. There is close pastoral and church supervision, and it is welcomed; but the Endeavorers feel that it is their society, for whose honor they are responsible, and whose victories depend upon themselves. As far as possible, this spirit should be incorporated in the Sunday-school, so that the Bible study may not seem a work impressed on the scholars, but elected by them,—their work, and not their teachers'.

How can the Christian Endeavor society help the Sunday-school? Greatly in its prayer-meetings, by remembering the allied Sunday-school topic of the morning. Here is a chance for the teacher to enlarge upon some theme treated too hurriedly in the lesson hour, and for scholars to show their appreciation of their teacher by repeating some thought he brought out in the morning. If rightly managed, the Christian Endeavor meeting furnishes an admirable opportunity for advertising the Sunday-school, and practically applying the truths there taught.

But the help given may be far more direct. Every well-organized Christian Endeavor society has a Sunday-school committee, whose members put themselves under the direction of the superintendent, and make it the one object of their term's work to push in all possible ways the interests of the Sunday-school.

The members of this committee are usually chosen with an eye to their fitness for acting as substitute teachers. Sometimes the committee constitutes itself a normal class and studies the lessons a week in advance, considering especially the way to teach effectively. On the next Sunday, therefore, the superintendent will find any of these Endeavorers well prepared to fill a vacancy.

Everywhere, too, these Sunday-school committees help the busy teacher to look after the absent scholars and to care for the sick. It is far easier for these young people than for the teacher to learn the real causes of absence and to urge better attendance. In some schools the teachers fill out blank cards every Sabbath, giving the names of absentees or of the sick on whom they would like to have the Sunday-school committee call. These cards are collected, the calls made, and then the Endeavorers report to the teacher.

A kindred ministration is the gathering of new scholars. In many cities the Sunday-school committee has conducted a fruitful house-to-house canvass for new scholars, sometimes canvassing at the same time for new members of their society. Other committees distribute printed cards of invitation. Others organize "recruiting squads" among the scholars, and give little rewards to those that do the best work. Others make it their business to hunt out all the young strangers in the morning congregation and give them a personal invitation to the school. Still others distribute among the scholars "suggestion blanks," on which each scholar writes the names and addresses of young folks that might be won for the school. These Endeavorers call at the strangers' homes and go with them to the school, while others stand ready to welcome all strangers at the door and show them to appropriate classes. Thus they follow them up, that it may not be a case of "light come, light go."

The Endeavorers, under the direction of their Sunday-school committee, may be very helpful in the music. A choir or an orchestra may be organized from their numbers. An occasional song appropriate to the lesson may be rendered as a solo or quartette. When Sunday-school concerts are to be given, the Endeavorers will afford trained assistance. But especially the committee should become thoroughly familiar with the Sunday-school song-book, so that its members, scattered over the room, may carry with vigor any unfamiliar hymn, and give force and sprightliness to all the singing.

The Sunday-school librarian will find among the Endeavorers some efficient aids. The Sunday-school committee may advertise the new books in the Christian Endeavor meetings, and get the society to add to the library certain books of especial interest and helpfulness to Endeavorers. Sunday-school library socials have been held by some societies, the evening's exercises being so planned as to call attention to the best books in the library. The Endeavorers will help in covering books, in hunting up those that are lost, in reading new books and giving an opinion regarding them. Where subscriptions are taken for special papers or magazines, the Sunday-school committee will be glad to undertake this work. After these periodicals have been read, they will gather up the old copies to send to the hospitals.

The decorating for Christmas and Easter exercises or for Children's Day may be assigned to the Christian Endeavor society. The Endeavorers may be set to gathering in the scholars for Rally Day. They should be called upon for help on all such special occasions.

Some societies give parties now and then to the classes that have the best record, or divide the school into sections according to age, and entertain each section in turn at a Christian Endeavor social, closing the series with a pleasant evening spent with the teachers and officers alone.

It would weary you if I should rehearse all the ways in which Christian Endeavor societies have proved helpful to the Sunday-school. Many a primary department has gained much from close association with the work of the superintendent of the Junior Christian Endeavor society. I have heard of a large number of places where the Endeavorers organized and maintained mission Sunday-schools—schools that in many instances have grown to churches. Often the Endeavorers take charge of the ushering of the school, furnish flowers for every session, offer rewards to the scholars for excellence in various directions, help with swift feet in the messenger service of the home department, turn their trained forces into an occasional Sunday-school prayer-meeting,—indeed, they are as ingenious in discovering ways of helping this elder sister of the Christian Endeavor society as they are zealous and persistent in these labors after they are inaugurated.

If in some churches this help is not given, it is probably because it is not invited, or very likely through lack of organization. If the Christian Endeavor society has no Sunday-school committee, let the Sunday-school superintendent, who is a member of the society ex officio, interest himself in obtaining one. And then through this committee he can draft into the service all the other usual committees of the society—the lookout committee, to get new scholars; the prayer-meeting committee, to aid in the school's devotional exercises; the temperance and missionary committees, to give assistance in the special lessons on those themes; the music committee, to aid in the singing, and the flower committee, to help in the decorations; the social committee, to seek the absent and the sick; the good-literature committee, to help the librarian.

And if the Endeavorers do this, or a part of this, for the Sunday-school, why should not the Sunday-school do a little for the Christian Endeavor society? The superintendent may help it by calling upon it for assistance and by recognizing on fit occasions its officers and committees. He may even give it an occasional advertisement from the desk; and he, with his officers and teachers, may do much to put himself in touch with the young people by attending the Christian Endeavor meetings now and then. The teachers may help by introducing into their talks before the classes an occasional hint on the Christian Endeavor pledge or committee work, or by remembering the prayer-meeting topic and suggesting a thought or two that may be developed in the meeting, or by urging membership in the society upon those that do not already belong to it.

Thus it is seen how intimately these two organizations are related, and how much each may do to help the other. Do not allow them to labor apart. Parallel threads are weak; cables are made by twisting them together.
