decisively important all these inquiries are for the future of the library, and however interesting and clear the arguments and conclusions on those subjects may be. But what it may properly do is, to state, without any pretence of novelty, but simply in order to refresh the public memory, the chief heads of a doctrine of her public libraries from a practical point of view. First (to limit the discussion). What a free public library is _not_ for. It is not for a nursery; a lunch-room; a bed-room; a place for meeting a girl in a corner and talking to her; a conversation-room of any kind; a free dispensary of stationery, envelopes, and letter-writing; a free range for loiterers; a campaigning field for mendicants, or for displaying advertisements; a haunt for loafers and criminals. Indeed, not to specify with inelegant distinctness, a free public library, like any other similarly commodious place of free public resort, would, if permitted, be used for any purpose whatever, no matter how private or how vicious, which could be served there more conveniently than by going to one's own home, or than by having any home at all. It would be so used systematically, constantly, and to a degree of intolerable nuisance; and its purification from such uses, if they have been set up, will be met with clamor, abuse, and with any degree and kind of even violent resistance which may be thought safe, or likely to succeed. Let it not be supposed that this is an imaginary picture. It is in every point taken from actual and numerous instances, and could be illustrated by a sufficiently ridiculous series of single adventures, by any librarian of large experience. Open public premises for some of the purposes above specified might conceivably be properly supplied by the public. What is here affirmed is, that public libraries are not at present proper for them. [4] San Francisco is at present taxed on a precise scale of one dollar to the hundred dollars of value, and on an annual total valuation of $200,000,000, which is, however, in practice somewhat, but not largely, exceeded. Second. What such a library _is_ for.
