Dr. Luther H. Gulick makes the statement, that "there are conditions for each individual under which he can do the most and the best work. It is the business of those in charge of others to ascertain these conditions and to comply with them." We hear so much in our day about scientific management that we may be led to begin inquiring skeptically if its value is not exaggerated in the interests of professional organizers, systematizers, etc. No working chart for computing the energy of a mental effort or for the increase of its productiveness has as yet been devised but none of us will deny the need of a working plan for the day's work. Else we drift. According to the new doctrine as laid down by Mr. H. N. Casson, "there is no such thing as unskilled labor, there is an intelligent method for every accomplishment. Scientific management does not mean frenzied production. On the contrary, it individualizes the workman, it means the better ordering of the work for the best interests of both individual and the service. Consequently, it provides for recreation as well as for work. It insists that the individual shall not sag so far down at the end of the day's work that he will not recuperate." This concerns not only expended energy but misdirected energy. The day's schedule should be so arranged that work requiring the highest mental effort be assigned to the most fruitful hours of the individual, the work so distributed that each individual performs the task he can best do and is most worthy of his highest skill. Pride in the work under your hand, the sense of doing something worth while, generates the spirit of loyalty and happiness which reckons, not so much with the written library regulations, as with the unwritten law of the service to stand by cheerfully as long as needed.
