One of the earliest of the more modern and characteristic of the commercial structures of Chicago, the Field Building, is by Mr. Richardson also, a huge warehouse covering a whole square, and seven stories high. With such an opportunity, Mr. Richardson could be trusted implicitly at least to make the most of his dimensions, and large as the building is in fact, it looks interminably big. Its bigness is made apparent by the simplicity of its treatment and the absence of any lateral division whatever. Simplicity, indeed, could scarcely go further. The vast expanses of the fronts are unrelieved by any ornament except a leaf in the cornice, and a rudimentary capital in the piers and mullions of the colonnaded attic. The effect of the mass is due wholly to its magnitude, to the disposition of its openings, and to the emphatic exhibition of the masonic structure. The openings, except in the attic, and except for an ample pier reserved at each corner, are equally spaced throughout. The vertical division is limited to a sharp separation from the intermediate wall veil of the basement on one hand, and of the attic on the other. It must be owned that there is even a distinct infelicity in the arrangement of the five stories of this intermediate wall, the two superposed arcades, the upper of which, by reason of its multiplied supports, is the more solid of aspect, and between which there is no harmonious relation, but contrariwise a competition. Nevertheless, the main division is so clear, and the handling throughout so vigorous, as to carry off even a more serious defect. Nothing of its kind could be more impressive than the rugged expanse of masonry, of which the bonding is expressed throughout, and which in the granite basement becomes Cyclopean in scale, and in the doorway especially Cyclopean in rude strength. The great pile is one of the most interesting as it is one of the most individual examples of American commercial building. In it the vulgarity of the “commercial palace” is gratefully conspicuous by its absence, and it is as monumental in its massiveness and durability as it is grimly utilitarian in expression.
