One is that of a graded supplemental lesson for each department. Some regard this as an essential, and consider no Sunday school properly a graded school without it. We regard it as important, but do not look upon it as one of the necessary features. There is need of a supplemental lesson; it will greatly aid in making the Sunday school efficient, and it should be adapted to the various grades. But the supplemental lesson, valuable as it is, we do not regard as one of the essential features of the graded system. Another is that of the annual examination. There are a few Sunday schools which require the pupil to pass an examination as the condition of promotion. This follows the analogy of the public school; but in our judgment it is not an essential part of the graded system. The examination in the Sunday school must of necessity be a very easy one, since it is upon lessons studied but little at home and given for a few minutes only once a week. It is apt to be a mere form, and sometimes is only a pretense. While we recommend examinations we believe that they should be left optional, and that the requirements for promotion should be those of age, general ability, and fitness of character. Some reward might be given in the form of a certificate, but it should not be necessary to obtain the certificate in order to receive promotion. THE AKRON PLAN. BY HON. LEWIS MILLER. AFTER an experience of more than twenty-five years with the graded system as carried on in our Akron Sunday school it can with confidence be recommended to others. It embraces the entire school for all this time, but more especially a course of sixteen years which I will try to explain. Our rooms are a great convenience, and aid much in perfecting the classification; the system, however, can be carried on in any of the present Sunday school rooms; in fact, for a number of years this system was a success in a church at Canton, O., also in the old Akron Church. In each case there was one larger room and but a few separate small rooms. The classification is based on the age of the scholar; if, however, a scholar seems from some cause to have advanced beyond his age in his general studies, which in most cases is determined by his standing in the public schools, such scholar is put in a class suited to his advancement. The following analysis will show more definitely the system. THE INFANT DEPARTMENT
