(1) _The School as a Whole._ The close observer, looking at the entire school, notes first of all that its gains and its losses in membership are at the extremes of its constituency. It is the normal condition for the gains to come in the Primary section; for the little children in families are attracted to the school or brought there by older children. There is almost invariably a constant increase in this department, requiring frequently the organization of new classes in the grade above, among the younger boys and girls. But, on the other hand, there is a constant loss of older scholars. In most schools, at the age of fourteen, in what is known as the early adolescent period of life, the pupils, for one reason or another, begin to drop out, and few enter to take their places. Almost every school is thus growing at the bottom and dying at the top. The Primary classes are full, but the classes of those above fourteen years are usually small--two large boys here, three yonder. And although girls continue in the school more frequently than boys, there will appear the same conditions--some large classes of girls and young women, but others where discouraged teachers are sitting down with one, two, or three pupils. Six or eight years ago these same classes came out from the Primary Department, each with eight or ten pupils; now they are mere skeleton classes, barely alive, and threatened with dissolution. Every earnest, thoughtful superintendent would rejoice to find some plan that will guarantee large classes of young people between sixteen and eighteen years of age, for this is the most vital period in the life of the individual. Such a plan is proposed in the graded system. (2) _The Condition of the Classes._ Fixing the attention upon the several classes, the critic of the school system notes three unfavorable conditions: (a) There is the inequality in the size of classes, to which reference has already been made. When classes come together by accident, pupils bringing their friends, or new members joining whatever classes they please, some classes of boys or girls will inevitably be too large for good government or good teaching, and others will be too small to create any enthusiasm, either in the teacher or the pupils. (b) There is also an inequality in the ages of pupils in the same class. A class may include one pupil or two pupils sixteen years old, and others as young as ten, or even nine years; some who during the week are in the high school, and others who can scarcely read the verses assigned to them.
