Along with symmetry, the logical development of the plan in study keeps in mind something of the rough form of the exterior design, with particular reference to the grouping of its masses to secure the maximum of air and the best light for the various departments. With the best designers, it is an unwritten law, that the next step after completing a satisfactory plan, is to sketch a section through the building, not only to ensure a proper proportion in the enclosed rooms, but most important of all to secure a system of fenestration, allowing wall space where needed and introducing the light as near the top of the rooms as the finish will permit. Having settled then all the details of plans and section, wherein are comprised all of the matter of greatest moment to the practical librarian, it only remains for the architect to prepare a suitable exterior and I certainly agree with my old preceptor that "it will come." The American people believe that education is the corner stone of manhood and good citizenship, and next to our public schools, if not before them, the most potent educational factor is our public library. The librarians are responsible in a great measure for the good work which is being accomplished in the dissemination of knowledge and culture among the people, but let me ask, are we not as responsible for our share, as co-workers with them, to perpetuate in lasting masonry the best which in us lies for the same great cause of the education of the people? What renaissance has failed to find literature and architecture quickened alike? The awakening of a love of the beautiful brings a thirst for knowledge concerning the beautiful; as the records will show, the interest excited by that marvellous assemblage of architectural masterpieces at the Chicago Fair, created a demand on the libraries almost beyond belief for books on architecture and the allied arts. Every conscientious architect must feel his responsibility to his clients as well as to the people and strive he must, to combine the ideal in convenience with simple beauty in design; my one plea is that such a combination is not only _possible_, but in intelligent hands, should be universal, and if my beliefs, hopes and expectations find sympathy with you, I shall feel repaid in the security of a harmonious co-operation between architect and librarian in the great work which stretches ahead of us into the future.
