When, from the time Evelyn was seven years old, it became necessary in her education to call in special tutors in the languages and in mathematics, and in certain arts that are generally called accomplishments, Miss McDonald was always present when the lessons were given, so that she maintained her ascendency and her influence in the girl's mind. It was this inseparable companionship, at least in all affairs of the mind, that gave to this educational experiment an exceptional interest to students of psychology. Nothing could be more interesting than to come into contact with a mind that from infancy onward had dwelt only upon what is noblest in literature, and from which had been excluded all that is enervating and degrading. A remarkable illustration of this is the familiar case of Helen Keller, whose acquisitions, by reason of her blindness and deafness, were limited to what was selected for her, and that mainly by one person, and she was therefore for a long time shielded from a knowledge of the evil side of life. Yet all vital literature is so close to life, and so full of its passion and peril, that it supplies all the necessary aliment for the growth of a sound, discriminating mind; and that knowledge of the world, as knowledge of evil is euphemistically called, can be safely left out of a good education. This may be admitted without going into the discussion whether good principles and standards in literature and morals are a sufficient equipment for the perils of life. This experiment, of course, was limited in Evelyn's case. She came in contact with a great deal of life. Her little world was fairly representative, for it contained her father, her mother, her governess, the maids and the servants, and occasional visitors, whom she saw freely as she grew older. The interesting fact was that she was obliged to judge this world according to the standards of literature, morals, and manners that had been implanted in her mainly by the influence of one person. The important part of this experiment of partial exclusion, in which she was never alone' an experiment undertaken solely for her safety and not for her training-was seen in her when she became conscious of its abnormal character, and perceived that she was always under surveillance. It might have made her exceedingly morbid, aside from its effect of paralyzing her self-confidence and power of initiation, had it not been for the exceptionally strong and cheerful nature of her companion. A position more hateful, even to a person not specially socially inclined, cannot be imagined than that of always being watched, and never having any assured privacy. And under such a tutelage and dependence, how in any event could she be able to take care of herself? What weapons had this heiress of a great fortune with which to defend herself? What sort of a girl had this treatment during seventeen years produced? VIII
