In countless other ways the same fact is shown. Half a century ago a youth who desired to become a lawyer or a doctor entered the office of a practitioner and learned his profession by practise and experience. Now he goes to the school of law or medicine and gains his entrance to his chosen calling by the way of books and laboratories. Even commerce and trade, in which the rules of practical experience seem most firmly entrenched, are shifting their basis to books, and schools of commerce and trade schools are springing up on every hand to give youth a broader foundation of knowledge than can be gained from practise. Still more significant are the facts shown by the enormous development of agricultural experiment stations, farmers' bulletins and farmers' institutes. Agriculture, that calling which of all others is most ancient and most conservative, is rapidly changing its basis from tradition to books. Perhaps I ought not to say "most conservative," for there is one calling which may better deserve the title--that of the domestic industries practised by women. Yet even here a beginning of the transfer, although a small one, has been made by schools of domestic science. While this beginning is but small, and while the traditional professions of women have not yet been greatly modified by books, the life of no class of the community has been more profoundly affected by this general change than has that of women. With the passing away of home industries and with the great increase of wealth which the past century, or half century, has seen, have come vastly increased opportunities to women for leisure, for release from domestic duties, and for the prolongation of school life. The statistics of high schools and colleges sufficiently show the use which they are making of this leisure. Other facts are equally obvious and significant as showing the transfer of the basis of woman's life from domestic experience to books. The woman's club, I suppose, may be said fairly to take the place of the sewing circle of our mothers and grandmothers. The contrast even in the name is significant, as marking the transfer of interest from the circle of domestic experience to the wider domain of the recorded life of the world, to the realm of books. Thus at whatever point we examine the life of the present, we find it basing itself on books, both for action and enjoyment, and that in an ever-increasing degree. This truth is peculiarly evident to you as librarians, since the facts of your own profession and the rapid growth of libraries and library work afford one of the latest phases of this general movement.
