Still another piece of symbolism is expressed in this interesting series of pictures by the trees, their foliage forming the background against which the central figure is placed. The oak in the central panel has been spoken of. In the design representing Peace and Prosperity, an olive-tree typifies not only Peace but Spring; in the next panel, that of Good Administration, the tree is the fig, and the season summer; in that of Corrupt Legislation, the autumnal vine, hinting at a too abundant luxury, and with its falling leaves presaging decay; and in that of Anarchy, bare branches and Winter.

The Second Floor Corridors.—Returning again to the Entrance Hall proper, the visitor may most conveniently continue his tour of the Library by ascending the Grand Staircase to the beautifully decorated corridors of the second-story arcade, on his way to the public galleries of the Main Reading Room. The corridors are arranged like those which the visitor has already passed through on the first floor, but their greater height and the brighter tone of the decoration give an effect of considerably greater spaciousness.

The Decoration of the Vaults.—The floors of the corridors are laid in mosaic of varying patterns. The ceilings are uniformly a barrel vault, with pendentives—the same, that is, as those of the North, East, and South Corridors below. The vaults are covered with a painted decoration of Renaissance ornament which for variety and interest is hardly surpassed anywhere else in the building. The decorative scheme which has been adopted was planned throughout by Mr. Casey, and elaborated, especially in the matter of color, and carried into effect, by Mr. Garnsey, working under Mr. Casey’s direction. In addition, each corridor contains, as a distinctive accent of color and design, a series of paintings by a specially commissioned artist—in the West Corridor by Mr. Walter Shirlaw, in the North Corridor by Mr. Robert Reid, in the East Corridor by Mr. George R. Barse, Jr., and in the South Corridor by Mr. Frank W. Benson. In the side corridors, also, at the west end, the arch of the vault is spanned by a broad band of stucco ornament containing a series of octagonal coffers, ornamented in relief by Mr. Hinton Perry.

The decoration is varied, of course, from corridor to corridor, in order to prevent any monotony of impression, but the main principles on which it is based are everywhere the same. Thus the color scheme—which was suggested in part by the beautiful Library in Sienna—comprises in every corridor blue in the pendentives, golden yellow in the penetrations, and a grayish white in the body of the vault. The only exception to this rule is in the West and East Corridors, which are terminated by double arches instead of ending directly upon a wall. Here the end penetrations are red and the pendentive yellow. The others remain as before. The delineation of the spaces is at bottom very simple, and though more elaborate, a good deal like that already noted in describing the mosaic in the lower corridors. The penetrations are outlined by a bright colored border, on which, where the lines converge to a point at the top, rests a border of greater width, enclosing the entire vault in a single great rectangle. This, in turn, is divided into compartments by bands of ornament, varying in number according to the requirements of the decoration, but always occurring immediately over the columns of the arcade. These bands, coming where they do, perform a vital service for the decoration in continually reminding the visitor, if only by a painted arabesque, of the importance of the arch in such a piece of construction as a vault. In the spaces between them are garlands and wreaths, and panels for paintings and inscriptions—the whole making part of one great arabesque, which is as easily intelligible and coherent as it is various, but which would have been bewildering in its wealth of ornament and color if it had not been for the fundamental service performed by these various bands and borders and broad masses of color.

The penetrations and pendentives are richly embellished with a great variety of ornament, both conventional and otherwise. The treatment differs in different corridors, however, on account of the varying relative position of the paired columns which support the arcade—from which results first a series of wide and then a series of narrow pendentives. Where the former occur—in the West and East Corridors—they are ornamented with the decorations of Mr. Shirlaw and Mr. Barse; while the narrower pendentives on the north and south carry simple medallions and tablets, and Mr. Reid’s and Mr. Benson’s paintings find place in the arabesque of the ceiling vault and in circular frames along the wall beneath. The balance is restored, however, by introducing a series of medallions, corresponding to Mr. Benson’s and Mr. Reid’s, though smaller and of less importance, in the vaults east and west, and by ornamenting the penetrations in the side corridors with greater richness and elaboration.

The Printers’ Marks.—The most interesting decoration of the penetrations, however, is a series of “Printers’ Marks” which is continued through all four corridors. Altogether there are fifty-six of them—sixteen in each of the side corridors, ten in the West Corridor, and fourteen in the East Corridor. They are painted in black outline, and are of a sufficient size, averaging about a foot and a half in height, to be easily made out from the floor. By a printer’s mark, it should be explained, is meant the engraved device which the old printers used in the title-page or colophon of their books, partly as a kind of informal trade-mark guarding against counterfeited editions, and partly as a personal emblem, such as a publisher of good standing would like to see on a long list of worthy books. For this latter reason, and in order to be able to add an interesting piece of ornament to the title-page, the mark has been revived of late years by a considerable number of modern publishing and printing houses.
