for the young, there are many which are not merely trashy but are positively pernicious. The Sunday-school library is an instrument of great power in forming the tastes, the opinions, and the habits of the people, and it is of the utmost moment that the books be pure in doctrine and healthful in moral and religious tone. 6. The Sunday-school concert, in which the exercises are prepared chiefly by the school itself, will be of great value if wisely conducted; but care is needed to exclude exercises introduced for sensational effect which may not befit the Lord's Day. Indeed, it is all-important that the exercise should not be degraded into a mere exhibition, awakening on the part of teachers and scholars only a desire to produce a popular sensation and draw the crowd, and on the part of the people a desire to be amused. The devotional spirit should always be dominant. But in addition to such exercises, it will be profitable to preach a sermon statedly--once a month, or at least once in three months--expressly to the Sunday-school, adapting the whole service to the young. It brings the pastor and school together publicly and directly and recognizes the relation of the pastor to it as its chief instructor and guide. But in the sermon, as in every Sunday-school address, he should be careful that in attempting to be simple he does not become childish; the former is necessary to success, the latter is a common and fatal mistake. Finally, the hearty co-operation and sympathy, above suggested, of pastor and people with the school will ordinarily avert all difficulty on the question of the relation of the Sunday-school to the church; for any school, whether home or mission, which finds itself thus enclosed within the living sympathies of the church will instinctively recognize its position as belonging to the church and under its watch-care and guidance. Nor will the other evil, so widespread and unfortunate, of the non-attendance of the school on public worship be likely to be experienced; for the scholars, won by the pastor's personal interest in them, will be attracted to him and to his ministrations in the pulpit. +SECTION VII.
