To maintain the efficiency of the library staff it is necessary not only to consider the welfare of the individual during his working hours but to provide such material regard for his day's toil that his vitality and enjoyment of life may be conserved by having the means to afford the necessary comfort and social status consistent with our profession. To consider the importance of personal appearance, neatness in dress in our service with the public is simply to recognize the point of view of the library patron whose opinion is worth while, and how are we to exact this showing of "fine front" if we do not defray the cost thereof? It is difficult, if not physiologically unsound, to speak about the mental conservation of the library staff apart from its physical maintenance, but in considering the former I would invite your attention to what Mr. P. W. Goldsbury so aptly calls "the recreation through the senses." Mr. Goldsbury remarks, "the importance of our understanding, the wide range of the functions of our senses, the influence of our surroundings and the manner in which they react on our minds." He illustrates his point by quoting the saying that "for horses the hardest road out of London is the most level one. There are no hills to climb and descend, and the tired horse has no chance to rest one set of muscles while another works. Monotony produces fatigue; and because this particular road is one dead, monotonous level, more horses give out on it than on any other road leading out of London." Irresistibly the moral of the canvas before us breaks in upon our individual sense of self-preservation and our responsibility for the welfare of others. For economic as well as for humanitarian reasons it behooves us to so apportion the day's work that one's senses are exercised one after another and through interchange of duties and tasks, not only one's body but one's mind is given a variety of exercise and impressions. The rotation of duties every two hours in departments where direct service with the public is given, will, I believe, be found to afford some relaxation and wholesome change to attendants on duty, especially so, if the change afford the alternative of stationary position and moving about.
