One of the first questions to be met in arranging a code of rules for the government of a public library relates to the age at which young persons shall be admitted to its privileges. There is no usage on this point which can be called common, but most libraries fix a certain age, as twelve or fourteen, below which candidates for admission are ineligible. Only a few of the most recently established libraries have adopted what seems to be the right solution of this question, by making no restriction whatever as to age. This course recommends itself as the wisest and the most consistent with the idea of the public library on many grounds. In the first place, age is no criterion of mental condition and capacity. So varying is the date of the awakening of intellectual life, and the rapidity of its progress, that height of stature might almost as well be taken for its measure as length of years. In every community there are some young minds of peculiar gifts and precocious development, as fit to cope with the masterpieces of literature at ten years of age, as the average person of twenty, and more appreciative of them. From this class come the minds which rule the world of mind, and confer the greatest benefits on the race. How can the public library do more for the intellectual culture of the whole community than by setting forward in their careers those who will be the teachers and leaders of their generation? In how many of the lives of those who have been eminent in literature and science do we find a youth almost discouraged because deprived of the means of intellectual growth. The lack of appreciation of youthful demands for culture is one of the saddest chapters in the history of the world's comprehending not the light which comes into it. Our public libraries will fail in an important part of their mission if they shut out from their treasures minds craving the best, and for the best purposes, because, forsooth, the child is too young to read good books.
