When for a moment one remembers the girl in her teens, the long line that lives in the memory from those just thirteen up through the sweetest and prettiest at sixteen, to the beautiful, graceful, and dignified ones just twenty, it makes a picture hard to equal. There is such evident joy in just living! When one catches a glimpse of the groups in their light dresses, with hair ribbons of every size and color according to the wearer’s interpretation of the latest fashion, wending their way to the high school, he feels that life is indeed a glorious summer morning. Though sighs and complaints may be heard over lessons too long and too difficult, they are not very deep, and are soon forgotten; though low marks do make very serious students with minds concentrated on work for a few days after report cards are out, yet with the majority the depression is short-lived, and life is sunshine once more. When as whistles blow and factory gates swing wide, one catches a glimpse in the early morning of the girl in her teens going to work, he hears snatches of happy laughter and jesting. No matter how hard the work, it cannot crush out the laughter in the heart of the girl in her teens; the good times after work is over or at the week end when she puts on her ribbons and gay attire make easier the crash of machinery and less painful the aching muscles. The girl in her teens is glad she is alive, and her evident and keen enjoyment of a world which some of her elders have found hard and a little disappointing does more to cheer and brighten the dull gray of the commonplace than she knows, or than we stop to remember. As we think of this long procession of the girl in her teens which memory can so easily recall, and then see in imagination the host of those who call themselves her teachers, we are tempted to cry, “Her teachers! What manner of beings are they who pretend to instruct, enlighten and guide all this energy, this fascinating line of possibility and promise!” It is easy to write or speak of the “ideal” teacher for all this fresh young life, filled with inexpressible longings for success and happiness. But the study of the very human and very real teacher, ideal only in the highest sense, in that she is struggling after perfection, will be much more practical and helpful to us. Should the teacher of girlhood in the years of the teens ever be a man? Yes, there have been many fine, successful teachers whose strength and manly qualities, whose sincere devotion to Christ and his teachings, have had a lasting influence for good upon the girl in her teens. It is a good thing for the girl to see the world and its relation to moral and religious life through the eyes of a far-seeing man. It is a help to her to get his mental grasp of situations as from week to week they follow together the life of Christ and his teachings or seek to understand the characters of Old Testament days.
