R. M. Hunt, Architect.] Another interesting piece of Gothic work, though this time of distinctly Victorian Gothic, is the house designed by Mr. Vaux for Governor Tilden. The interest of this, however, is rather in the detail of form and color than in general composition, since the building is architecturally only a street front, and since the slightness of the projections and the lack of visible and emphasized depth in the wall itself give it the appearance rather of a screen than of one face of a building, and the small gables which surmount it too evidently exist for the sole purpose of animating the sky-line. But the color treatment of this front is admirable, and recalls the best work of the most successful colorist in architecture whom we have ever had in New York--Mr. Wrey Mould. It is characteristic that interesting treatment of color, like every other properly architectural development, has been stopped short by the new “movement.” An unusually large variety of colors, and those of the most positive tints that natural stones supply, has here been employed and harmonized; and, what is even rarer, they have all been used with architectural propriety to accentuate the construction and to heighten its effect. An ingenious and novel use of dark granite, which when polished is almost black, and which is employed in narrow bands precisely where it is wanted, deserves particular remark. The decorative carving attracts attention chiefly by its profusion, and by the exquisite crispness and delicacy of its execution. In both these respects the only parallel to it is in the house of Mr. W. K. Vanderbilt, for, as we have seen, the carving upon the houses of Mr. W. H. Vanderbilt does not count. That this carving counts so fully is the result of the skill of the architect in fixing its place and adjusting its scale so that it everywhere assists the architecture, and is better in its place than it would be in another place.
