It has become quite popular now, in many schools, to organize each class into a distinct missionary circle, with a name and motto, as: "Earnest Workers," "The Harriet Newell Circle," "The Lambs of Jesus," "The Buds of Promise," "Dew Drops," "Little Travellers," "Willing Hearts," "Modest Workers," "Cheerful Givers," "Young Timothies," "The Sowers," "The Guiding Stars," "Youthful Disciples," "Rose of Sharon," "Little Samuels," "The Reapers," "Olive Plants;" etc. Each circle or class reports through a committee every month to the school. Sometimes each class has a small cheap banner, with its name printed on it. XXVII. SABBATH-SCHOOL MUSIC. This is a very important and attractive part of the exercises of a good Sunday-school, if rightly conducted. Good, pure, simple music, such as children love to sing, and words embodying the best Christian sentiments and feelings, should always be chosen. There is such an abundance of music at the present time, of an elevating, excellent character, that there is no excuse for adopting that which is doubtful. Some of the holiest Christian influences are carried weekly into little hearts and numerous families by these sweet songs of the children. It is well worth while for every Sunday-school to obtain a good supply of the best music, such as the children like; and they often love to meet on some afternoon or evening for the purpose of practising their music with their kind-hearted leader. It is the remark of a wise man: "Let me make the ballads of a nation, and I care not who makes its laws." How vastly important, then, it is to the future well-being of our youth that they be well supplied with the choicest words and music to praise God in these little assemblies! A few words of caution may be appropriate: Sing no more than that which will be truly worship and devotional on the Lord's day. Introduce all new hymns with great care to make the children _understand_ the true sentiment before they sing it. Consequently, not more than one new hymn should be presented to the school on any one Sabbath. Let the practice in them take place on a week-day, or so as not to interrupt the worship of the Sabbath-school. Never should singing be introduced as an entertainment or diversion in the Sabbath-school, or made a hobby. Sacred music has a higher, holier mission. The hymns should be appropriate to the circumstances and occasion, and adapted in conformity to the Bible lesson of the day.
