or if it were possible for us with enlightened sympathy to gain access to the enchanted garden of youth, we should be more adequate guides for the boys and girls around us.  As it is we entirely fail to appreciate the heights of their ambitions, hopes, and joys, and we have no measure with which to plumb the depths of their fears, their disappointments, and their doubts.  The transition between radiant joy and confident hope in the future to a miserable misinterpretation of sensations both physical and psychical are rapid.  It is the unknown that is terrible to us all, and to the child the changes in its body, the changes in its soul and spirit, which we pass by as commonplace, are full of suggestions of abnormality, of disaster, and of death.  Young people suffer much from the want of comprehension and intelligent sympathy of their elders, much also from their own ignorance and too fervid imagination.  The instability of the bodily tissues and the variability of their functions find a counterpart in the instability of the mental and moral natures and in the variability of their phenomena.  Adolescents indeed “never continue in one stay;” left to themselves they will begin many pursuits, but persevere with, and finish, nothing.

Youth is the time for rapidly-succeeding friends, lovers, and heroes.  The schoolfellow or teacher who is adored to-day may become the object of indifference or even of dislike to-morrow.  Ideas as to the calling or profession to be adopted change rapidly, and opinions upon religion, politics, &c., vary from day to day.  It is little wonder that there is a special type of adolescent insanity differing entirely from that of later years, one in which, owing to the want of full development of mental faculties, there are no systematised delusions, but a rapid change from depression and melancholy to exaltation bordering on mania.  Those parents and guardians who know something of the peculiar physical and mental conditions of adolescence will be best prepared both to treat the troubles wisely, and by sympathy to help the young people under their care to help themselves.

One of the phenomena of adolescence is the dawn of the sexual instinct.  This frequently develops without the child knowing or understanding what it means.  More especially is this true of young girls whose home life has been completely sheltered, and who have not had the advantage, or disadvantage, of that experience of life which comes early to those who live in crowded tenements or amongst the outspoken people of the countryside.  The children of the poorer classes have, in a way, too little to learn:  they are brought up from babyhood in the midst of all domestic concerns, and the love affairs of their elders are intimately known to them, therefore quite early in adolescence “ilka lassie has her laddie,” and although the attraction be short-lived and the affection very superficial, yet it is sufficient to give an added interest to life, and generally leads to an increased care in dress and an increased desire to make the most of whatever good looks the girl may possess.  The girl in richer homes is probably much more bewildered by her unwonted sensations and by the attraction she begins to feel towards the society of the opposite sex.
