WE can hardly find words to convey our impression of the surpassing importance of these classes. To train teachers, to train mothers and fathers, to restrain from doubtful company, and to furnish good companions and Christian associations, reading, habits, impulses to the young men and women of this generation, is a work worthy of the highest aspirations of the best and noblest of our race. If we look at the census, we cannot fail to notice the striking fact that a little more than one-third of the entire population of New York are young men and women over fifteen and under thirty years of age, while more than one-half of our population is under twenty years of age.

In a very short time the destinies of our country and of our churches will be in the hands of these young people. To a large extent they have been neglected in the family, in society, in the Sabbath-school, and in the Church; and as Dr. James W. Alexander said: "Be it ever remembered, that the neglecters of the Church have been neglected by the Church." These young people can no longer be petted as children, and they are not generally treated with the respect due to them as rising young men and women. Said a youth of fifteen once: "Uncle, I don't know what I can do with myself. I am too old to play with children, and I am not old enough to be interesting to the older people." This anomalous position such young people sadly feel. They are sensitive, beyond any other period of life, to any slight or neglect, and after a vain struggle to gain a recognition and position anywhere, they rush to the gilded saloons or the giddy dance for that sympathy, kindness, and regard which they vainly seek for in the family, the Sabbath-school and the Church of Christ.

This should never be, and it must not be. But can these persons be reached and gained by the Sabbath-school? And how? After due consideration, I reply, in the first place, that they can be reached. My reasons are:

1. Because earnest, warm-hearted, disinterested efforts in this direction have ever been successful. When building the Brick Church in Rochester, N.Y., the names of all the scholars and their ages were transcribed and placed in the corner-stone, when it was ascertained that, of the whole number—I think 652—the average age was fourteen years and ten months; and other churches in that city present a similar record, because the able and influential Christian business men and women of Rochester devote themselves to this great work.

2. Because no class of persons is more susceptible to kind attention and real sympathy. They are quick to perceive and prompt to act. No class is more hopeful.

3. Because these senior classes, when appropriately conducted, are well adapted to meet the wants of their personal, social, intellectual, and religious nature, and to fill a secret void that is keenly felt by these precious youth.

In the second place, How can our young men and women be reached? I answer:

1. Christian men and women of real talent and character, of religious and social position, must be thoroughly aroused to a self-sacrificing, devoted, heartfelt interest for them. They must put their hearts into it. No feigned respect will do. Nothing but real sympathy will be received. No mere professions will answer. These youth are quick and sharp-sighted to detect anything insincere or unreal. The best men and women of our churches must be chosen to take charge of their classes—persons who can and will understand, appreciate, and respect young people. They must evince a more anxious and watchful desire to notice and approve what is right in them, than to condemn that which is wrong. They must be patient and forbearing, with a good control of their countenance, tone of voice, language, quick to discover the value and bearing of the half-uttered opinions of the class, with an earnest personal interest in each one and all things that concern them. They should be enabled to prove themselves sincere friends and counsellors of all—both for this life, in employment, business, social questions, amusements, etc., and for the life that is to come. They should have an intelligent enthusiasm in the great work, with a strong faith in God, in his Word, and in his Spirit, and a hearty good-will to man.

2. Lay your plans for these classes on so large and liberal a scale as to command the scholars' respect as well as your own. Render them as pleasant and as attractive as possible. Make the best arrangements you can as to room, seats, library, and periodicals. I am sure The Sunday-School Times and other Sabbath-school journals and magazines, would be very useful in such a service. Do all you can to raise these classes in their own estimation, and omit no opportunity to cherish self-respect on the part of each member, and try to inspire them all with higher aspirations and better hopes. Manifest, as well as feel, a personal interest in each one.

3. Aim high and direct. Have a distinct, definite aim and object in all your teachings, and see that each member of the class clearly understands it. Young people want drawing out and leading forward in gentle confidence. In these classes we ought to select and train for the purpose our best Sabbath-school teachers. If the exercises are allowed to degenerate into unprofitable discussions, the examination of curious questions, controversies, or skeptical subjects, they may be productive of positive evil. Care should be taken, therefore, to engross them with the most ennobling themes. None can better appreciate what is truly excellent than these young people. An appeal to the Word and to the Testimony they will understand and respect. Lead them to compare Scripture with Scripture. Illustrate the Old Testament from the New, and also bring illustration for the New Testament from the Old. Induce the young people to make the best use of a good reference Bible, searching out parallel passages for comparison, inference, and illustration, and all will be interested and benefited. Use similes, metaphors, etc., which so abound, as well as comparisons and inferences. The following quotation may serve as an illustration of four figures of speech, all brought into one sentence:

"Imagine a father bewailing the loss of his son, by drowning.

Simile—He stood firmly upon the beach, like an oak of the forest,

Metaphor—and cried out, with trumpet voice,

Hyperbole—louder than the cannon's roar:—

Apostrophe—Oh ocean! thou hast robbed me of a beloved and courageous son."

4. The character, interests, and feelings of the class should be the teacher's unwearied, daily study. This will be a noble work. Nothing which concerns them should be treated by the teacher with indifference. His profoundest thoughts, reading, observation, and study should be laid under contribution to his class. Painstaking saves thousands, neglect ruins millions. Count no sacrifice too dear to win souls.

5. It is indispensable that the teacher of such a class should always be courteous. Religion should at least make its possessor a gentleman, and this the young people all know right well. His whole life and bearing will influence the little circle. The personal appearance also should be duly regarded. Says a teacher: "The manner of a teacher should always be marked by these qualities: 1. Animation—a quickened, active state of the whole soul; 2. Intention—the aim and endeavor to impart the information required; 3. Earnestness—zeal in executing the instruction."

6. The class should be consulted, as far as possible, respecting the subject of study. The teacher should lose no opportunity to evince his respect for their opinions. His difficult questions should be asked generally of the class, while the personal questions should be easy and adapted. He should receive all their answers with an abounding charity and confidence, and make the most of the feeblest responses. A tart reply to a single remark will ofttimes seal the lips and hearts of a whole class. They love confidence, and become afraid to trust a teacher with their stammering, half-uttered, imperfect answers, particularly if he appears more anxious to be smart and witty than to do them good and honor them. Let the lessons be systematic and complete. The teacher should aim to draw out the thoughts of his pupils in an easy way, instead of pouring in his own. "Thoughts, not words," should be the class-motto, and none can appreciate them better than young people. Let the illustrations be well-chosen and appropriate. If you strike an important practical question during the lesson, do not leave it until satisfactorily investigated, whether the lesson is covered or not. Let every mind be calm and unembarrassed, so that it will work well; much depends upon the class, as well as upon the capacity of the teacher. "A few pebbles, a piece of leather, and a cord, are in some hands, a more formidable weapon than the sword of a giant, although it be strong as a weaver's beam and keen as a blade of Damascus steel."

7. These young people should be especially induced to look into their own hearts, and study their own mental and moral mechanism. Lead them often to converse about themselves. It has been truly said, that "it is a law of human nature, that man is interested in nothing so much as about himself." Whatever relates to his own personal experience always claims his especial regard. Many quite fail as teachers, as well as preachers, because they are so impersonal.

8. Social meetings of the class should be held now and then, and pains should be taken to make them attractive and useful. Young men and women must have their social nature regarded. The teacher should on such occasions strive to recall the freshness and vivacity of his own youth, and live it over again; enter into it heartily, and show the class his acquaintance and sympathy with all their peculiar wants, fears, and trials. Band the young people together, in social bonds and mutual pledges if you please, to attend church, prayer-meeting, and Sabbath-school, to read the Bible and pray regularly, and perhaps pledge also against improper reading, associates, games, drinking, smoking, late hours, neglect of the Sabbath, and unite them in associated literary efforts, in tract missions, Sabbath-school work, in visitation, and in all ways of doing good. There should be social prayer-meetings of the class at convenient times. Have, also, a well-chosen library for them, and point out from time to time the books best adapted to peculiar wants and circumstances.

9. Give each pupil distinctly to understand that every step in your efforts on his behalf is intended to lead him to Christ; that all there is to be desired in this life and in that which is to come, is embodied in this idea; that you expect, as soon as they get their minds clear upon the glad tidings of the gospel, that they will embrace them at once. Life is short, and there is no time to lose. Besides, young people when convinced are generally prompt to act, and therefore there is great encouragement. In fact, no field of benevolent effort is more full of hope and encouragement than this one of which we speak. In a Bible-class in one of our church Sabbath-schools not long since, fifty-five persons united with that church during the current year; and in another church and class, fifty, and in another still, thirty-four—all as the results of one year's labor. How glorious! Let then our sons and daughters, our clerks, scholars, and servant-girls, all be gathered without delay by the churches of Christ into these adult classes. Thus let the warm, burning influences of the living teacher reach every youthful heart. Says an earnest worker: "Among persons of all ages, truth most frequently has power when spoken by the living voice. The words of a teacher's mouth should be ever warm with the Spirit's breath, and strong with the vital impulses of his throbbing heart. Such words children feel." In the language of one of our Bible commentators, the truth evidently is this: "That personal effort for the souls of individuals—the lip, the thought, and the heart of a living man—brought into contact with the lip, thought, and heart of a living man, IS A GRAND INSTITUTION OF GOD FOR THE CONVERSION OF THE WORLD."

There is such a great necessity for adapting each lesson perfectly to the age, acquirements, etc., of the scholar, that I add a single specimen lesson from "The Sunday Teachers' Treasury." It is upon the same subject as that taken up in Mr. Wells's infant-class lesson—"The Passover"—and is given that, by comparison of style, the adaptation of the same lesson to infant and Bible-classes may be seen:
