One summer evening the windows of the cottage where Harold and his mother lived were wide open, and Harold was reading aloud to her. For a wonder, they were quite by themselves. The Librarian, who was a lonely old fellow without chick or child of his own, happened to be passing down the High Street when he heard the sound of a voice reading. It read so well that he stopped to listen. Presently he tapped on the door and begged to be invited within the better to hear the reading. The widow was very proud and pleased, you may be sure. She bade the Librarian welcome, and Harold continued to read until curfew sounded for every one to go to bed. The Librarian patted him on the head and asked if he might come again to hear such good reading. He came, in fact, the very next night. After that Harold usually had an audience of at least two on the long evenings, even when the other boys were busy. The Librarian became his fast friend. He liked to come to the little cottage better than anywhere else in the world, except to his own library. But at the library he in turn was host, and Harold became his guest. And he showed Harold many wonderful things in that library of which no one but the Librarian knew the existence,--strange histories, forgotten chronicles, wonder-tales. Gradually Harold became almost as well acquainted with the books as was the Librarian himself; though, of course, he did not at first understand them all. Nothing happens all at once. The other fellows called Harold the "Book-Wizard." The library was a beautiful building on the main square, close by the Lord Mayor's house and the belfry, where swung the great town bell. It was open freely to every one, from morning until night, and any one could always get any book he wanted, for there were many copies of each book. The caretakers always knew just where to find the book one wished. Or the reader might go in and choose for himself; which is a pleasanter thing when you have forgotten the name of your book, or do not know just which book you want most until you have looked about. The shelves of the library were nice and low, so that, no matter how little you were, you could reach the books without standing on tiptoe or climbing a dangerous ladder. And everywhere in the library were well-lighted tables to put books on, and cozy chairs, and crickets for your feet, and cushions for your back. There were wide window-seats, too, where between chapters one could curl up and look down into a beautiful garden. The air of the library was always sweet and clean. The books were always bright and fresh. There was no noise, nor dust, nor torn pages, nor cross looks to disturb one. The people who took care of the books were civil and obliging. It was indeed a very rare and unusual library. No wonder Harold and the Librarian and all the other citizens of Kisington loved it and were proud of it and used it very often.
