Introduce a myriad natural details, for which you must draw on a consecrated imagination. You should hear Mr. Moody tell a Bible story! It is not enough to say that Abraham determined to offer up Isaac as a sacrifice. The great, loving soul of the evangelist has brooded too long over the Bible for a statement so cold as that. He must tell about the patriarch's sleepless nights; about his getting up and going over to the bed of the boy so peacefully sleeping; about his weeping when no one was watching him; how he couldn't eat his breakfast; how his heart beat whenever he looked at the lad. And long before Mr. Moody is through, the great sacrifice is so vivid to him and to us that we all weep together, and no moralizing is needed. You are not Moodys? No; but hundreds of primary teachers are doing just this work, telling to their children the Bible stories as they must have happened, reading with the heart and telling them to the life. Long meditation is needed, persistent "putting yourself in his place," and it is even well to write out the story in full before you attempt to tell it. When you receive the reward, you will count the trouble as nothing. Music is a great aid in the primary room. If you cannot afford a piano, learn how cheap are the "baby organs," and how effectively they will lead the children's singing. Even though you work in an extemporized class-room, shut off by screens or a curtain from the rest of the school, you can at least use "whisper songs." Yes, and these whisper songs may often be motion songs, and serve to illustrate the lesson. At least one song of the hour should bear directly on the central thought of the hour, and before it is sung you should explain why you call for it. Most of the best songs for this purpose will prove to be standard hymns, and there is every reason why the simplest of these should be taught to the children, that they may find as many points of contact as possible with the services of the older church. The aid of the parents may well be invoked to teach these hymns at home to the children,--a helpful task, for more than the children's sake, at which to set the parents. The primary song-books contain bright little hymns appropriate to introduce prayer, to open and close the school, to be sung before Bible-reading and while the collection is taken. A clear-voiced assistant, sitting and singing among the children, will train them insensibly, and draw their childish voices into harmony with her own. Just as the children will enjoy a class name, motto, colors, so they will be delighted to select a class song; and this device may be tried, together with many others mentioned in the chapter on "A Singing Sunday-school."
