By far the most successful, however, of all the recent commercial buildings is the Post Building, designed by Mr. Post, and executed, above the blue-stone basement, in yellow brick and yellow terra-cotta. The site is an irregular tetragon at the intersection of three streets, and the court, made necessary by the depth of the plot, instead of being a well sunk in the middle of the building, is made a recess in one of the long sides.

arrangement is not only practically convenient, but, like every arrangement obviously dictated by practical convenience, is capable of becoming architecturally effective, and here becomes so. The openings are admirably well grouped between the powerful piers, and, what is a rare attainment in “elevator architecture,” there is abundant variety in their treatment, without the look of restlessness and caprice which generally attends an effort for variety in a many-storied building. The detail enhances the effect of this disposition. It is well adjusted to its function and position, nowhere excessive in quantity or in scale, and nowhere meagre, and it is in itself rich and refined. It is designed in “free Renaissance,” that is to say, the designer has undertaken to model the building faithfully, according to its plan and construction, in Renaissance architecture, leaving out all that he does not want. Mr. Haight, as we saw, was able to achieve that result without transcending the lines of academic Gothic. Mr. Post has put his academic Renaissance into the alembic of analysis, and where the analysis has been complete his Renaissance architecture has volatilized and disappeared. We are very sure that he had no real use for the imitations in terra-cotta of protruding key-stones, for example, and these are almost the only badges left his building of the style with which he started, except the capitals of the pilasters, and the Ionic capitals of the very pretty shafted arcade which forms the attic. But for these comparatively trivial incidents of his work, Mr. Post’s free Renaissance would have to be classified as Gothic, if it were really necessary to classify it at all, except as good architecture. Mr. Post, in fact, has done on his own account what the Romanesque builders did. They, too, were doing “free classic.” They began with classical Roman architecture, and, steadily leaving out what they did not want, they arrived at Westminster and Amiens and Cologne.
It is strange to see so thoroughly studied a performance as this succeeded by so thoroughly unstudied a performance as the Mills Building, by the same architect. But possibly ten-story buildings, which must be built in a year, will not wait for architects to mature designs which would make the buildings of interest to students of architecture as well as to investors. Whatever the cause may be, the result is unfortunate; for after the grandiose and somewhat swaggering Roman gateway, and the portcullis which it encloses, have been taken out, the rest of the Mills Building may safely be thrown away. The portcullis is really an interesting piece of iron-work both in design and in workmanship, although in both it is distinctly inferior to such a piece of work as the nondescript beast in cast iron that performs the humble office of holding a sign in Cedar Street, and that might have been wrought in the thirteenth century, so grotesque, so skilful, so chargedwith the spirit of artistic and enjoyed handicraft it is.

So the new departure is still but a departure, and it seems time that such of the victims of it as are artists who take serious views of their art should ask themselves why they continue to work in a style which has never produced a monument, and in which it is impossible to discern any element of progress. In doing Queen Anne, have they done anything but follow a fashion set, as fashions in millinery and tailoring are set, by mere caprice? A professional journal has indeed declared that “architecture is very much a matter of fashion,” and architects who take this view of their calling will of course build in the fashion, as they dress in the fashion, in spite of their own knowledge that the fashion is absurd. But it is impossible to regard an architect who takes this view as other than a tradesman, or to discuss his works except by telling what are the latest modes, in the manner of the fashion magazines. It seems impossible for architects who take this view of their art to take their art seriously—anything like so seriously, for example, as they take their incomes. But for architects who love their art and believe in it, the point of “departure” is much less important than the point of arrival, and by such architects the historical styles of architecture will be rated according to the help they give in solving the architectural problems of our time. We have seen that an architect who starts from Renaissance architecture and an architect who starts from Gothic architecture, if they faithfully scrutinize their precedents, and faithfully discard such as are inapplicable, in arriving at free architecture will arrive, so far as style is concerned, at much the same result. If this process of analysis were to be carried on for a generation, it would be as difficult, and as purely a matter of speculative curiosity, to trace the sources of English and American architecture as the sources of the composite and living English language, which is adequate to every expression. We have been blaming the architects for accepting the forms of past architecture without analyzing them. But, indeed, if architects had been analysts, they would generationsago have recognized in their work that we do live in times unknown to the ancients, whether of Athens in the fifth century before our era, or of Western Europe in the thirteenth century of our era; that within the limits set by fact and reason there is ample room for the exercise of all accomplished talents, and verge enough for the expression of all sane temperaments, while without these limits nothing can be done that will stand the test of fact and reason, which is the test of time; that “effects” cannot precede causes, and that the rudest art which is sincere is living and in the way to be refined, while the most refined art that has lost its meaning can never be made alive. The recognition of these things would have prevented a vagary like the frivolities and affectations of the new departure from attaining any vogue, but it would also have prevented the establishment of any technical styles in modern building, and instead of reproducing “examples” of one historical style and then of another, and then of a mixture of two, architects would be producing and writers would be discussing works of the great art of architecture.
AS an architectural work, the house of Mr. W. K. Vanderbilt is perhaps the most noteworthy of the four large and costly mansions herewith illustrated. In this a design intrinsically interesting has been carried out with an amplitude of means of all kinds which yet nowhere degenerates into profusion or mere ostentation. The dimensions are generous for a town house, and they have been made the most of by a breadth of treatment and an emphasis of structure, in the walls at least, which enable the building to carry with grace a wealth of ornament under which many buildings of equal size would disappear. The material is a soft gray limestone, which leaves much to be desired in color, though in texture it is equally adapted to the simple and massive treatment of the walls and to the minute delicacy of the decoration, both architectural and sculptural. It is very much to the credit of the designer that in spite of a richness without many examples in our domestic architecture, except in the other dwellings of this same series, the first impression of his work, and the most abiding, is that of power and massiveness. This is secured mainly by the unbroken breadth of the flank of wall between the porch and the angle on the Fifth Avenue front of the building—unbroken except by the simple and square-headed openings with which it is pierced, and the crisp and emphatic though

not excessive string courses which traverse it and mark the division of the stories. It is questionable whether this massiveness is not carried too far, but everybody will admit that an excessive weight of wall is a “good fault” in the street architecture of New York, and that of the two, a dwelling is more dignified which approaches the solidity proper to a prison than one that emulates the precarious lightness proper to a greenhouse. The depth of the porch and of the recessed balcony over it in the central division of the avenue front assists this expression of solidity, and helps the building to wear its burden of decoration “lightly, like a flower.” The richness, as we have said, is almost unexampled in New York. Of strictly architectural decoration—that is, of members and details which are usually designed by the architect of a building—there is a copiousness which is only saved by the means just indicated from becoming an embarrassment of riches. All this work is exquisite in execution. In design it is generally interesting and scholarly, though there is common to all of it the defect of being too small to be thoroughly well seen and thoroughly effective. The uniformity of this defect of scale seems to prove that the architect erred in estimating the effect of his design in the colorless material employed. The decoration of the recess of the balcony, too, loses effect by being entirely unrelated to the construction, and the stone trellis with which the turret at the angle is overlaid is equally irrelevant to the object to which it is applied. Architectural decoration ceases to be such when it ceases to be a development of the structure; and these exceptions, by their comparative ineffectiveness, confirm the wisdom of the rule by which elsewhere throughout the building the ornament is used to emphasize the structure, and thereby gains greatly in impressiveness and in charm.
The sculptural decoration, in contradistinction to that strictly architectural, equally abounds. By sculptural decoration is meant that designed as well as executed by the sculptor, and in regard to which the only care of the architect is to provide places for it, and so to frame it that, if it does not help, it may not injure, the architecture to which it is attached. It is not too much to say of this that it is much the most important and interesting work in decorative sculpture which is to be seen out-of-doors in New York. The most noteworthy piece of it, perhaps, is the procession of cherubic musicians girdling the frieze-like band of the corbel which carries the oriel of the southern front.[D]The execution elsewhere, in the panels under and between the windows, and in the pilasters of the bay, is equally good, but the design is nowhere else so effective. One need not be a purist, indeed, to find fault with the introduction of these pilasters at the angles of the bay and on the curve of the oriel, which are so clearly not structural members, actual or symbolic, and which are so clearly introduced for the sake of the ornament they bear, although he may condone the fault for the prettiness of the ornament generally in design, and its unfailing care and delicacy of execution. The only criticism possible, indeed, upon the execution of this work is, that it is too exquisite, and reduces the texture of carved stone too nearly to the more facile surface of moulded clay.
One’s admiration of Mr. Hunt’s spirited and scholarly design does not indeed cease with the walls of the house; but it must be owned that it undergoes some modification above the cornice. It cannot be said that the sky-line is so effective as might have been expected from what is beneath it. There is an undeniable piquancyabout the statued gable which terminates the roof of the principal mass, and the relation between this roof and the steep hood of the turret is picturesque, taken alone. Unfortunately, it cannot be taken alone, and the effect of the whole series of roofs is not a harmonious grouping, but—there is no other word for it—a “huddle.” It is in the roof, too, that the shortcomings of the architect in the solution of what may be called his academic problem are most apparent. The style of his work is the transitional style of France, the modification of mediæval architecture under the influence of the Italian Renaissance, until what was all Gothic at the beginning of the transition had become all classic at its close. This is, in fact, an attempt to summarize in one building the history of a most active and fruitful century in the history of architecture, which included the late Gothic of the fifteenth century and the early Renaissance of the sixteenth, and spanned the distance from the minute and complicated modelling of the Palais de Justice at Rouen and the Hôtel Cluny at Paris, to the romantic classicism of the great châteaux of the Loire. Certainly the attempt does not lack boldness. Here we have in one building the superimposed bases and interpenetrating mouldings of the latest French Gothic and the fish-bladder tracery of the Renaissance, and in the dormers the stride from the ogee canopies of Rouen to the prim pilasters and pediment of Orleans. Mr. Hunt’s skill has not sufficed to introduce together these features, the outcomes of different modes of thought as well as of different systems of construction, without a visible incongruity; nor are they in all cases successful, taken singly. The large and elaborate dormer over the entrance, especially, instead of being a visible reconciliation of the two styles, is a visible demonstration that they cannot be reconciled. A complete construction of post and lintel, of pilaster and entablature, is supplemented by another construction of flying buttresses which are clearly superfluous and irrelevant, and which, instead of resisting the thrust of an arch, have the appearance of ineffectually “shoring up” a structure which, though complete, is unstable.
One is inclined to ascribe the lack of unity and repose which the disturbed sky-line of the building entails upon it, and which somewhat impairs the dignity of an otherwise dignified and always animated design, to the angle turret of which the architect was evidently enamoured. We may share his liking for it, and admit it to be an extremely pretty thing, without admitting that it belongs to this building. The leading motive of the composition is evidently the “pyramidization,” to borrow Mr. Thomas Hope’s uncouth word, of the whole building towards the apex of the main mass at the angle, from the point of view from which the illustration is taken. It is clearly to assist and emphasize the ascent and convergence of all the lines of the building to this apex, and to enhance the apparent dimensions, that this mass is raised a story, and the extremities of the building allowed to fall away, and it is in order to account for the emphasizing of this mass by a separate roof that the somewhat awkward expedient has been adopted of dropping the cornice on the street side below the eaves. New York readers who are familiar with the aspect of the Dry Dock Savings-Bank in the Bowery will know what is meant by this “pyramidization,” and will remember how it is there attained. Now it happens that it is precisely this intention which in the present instance is obscured and partly defeated by the tormenting of the sky-line, which in turn may be traced to the insistence of the architect upon his extremely pretty but irrelevant

turret. It is a good lesson in architecture to find that the effect of a whole may be so much impaired by one of the most successful of the parts, and that even when “the thing” is really rich and rare, we may still be unsatisfied how it “got there.” Happily neither this shortcoming, nor shortcomings much graver, could prevent such a work as this from being an ornament to the city, and an honorable monument to its architect.
Perhaps it is because Mr. Post, the architect of the house of Mr. Cornelius Vanderbilt, has not attempted so much as Mr. Hunt that his work may be called at once more successful and less interesting. In color it has more and in design less of variety. For the monotony of gray wall and black roof it substitutes red brick, with wrought work of the same gray limestone employed in the house we have been talking of, and with a red slated roof broken by great stone dormers. It is much more simple and compact in composition than the other, for the main house is a parallelogram brought together under one great four-hipped roof, and the wing is here a very subordinate appendage. It is thus much simpler, much more within the conventional decorum of a town mansion in its scheme, while it is equally far from having the appearance of having been designed by contract, and is studied with equal thoroughness, although with a very different motive. In the matter of color, it is undeniable that the brick-work has in places a patchy look by reason of the comparatively small quantities in which it is used, the whole front on the avenue being virtually of highly wrought stone, and it seems clear that the building would have gained if the brick had been omitted altogether from this front. On the street front the mode of treatment adopted might very possiblyhave made the building dull and monotonous if it had been built in monochrome, as assuredly the addition of a strong contrast of color would have made the more varied design of the other painfully restless. In style the two buildings offer a curious resemblance and a curious contrast. This also is a French château, but a French château of the period after the transition, when all detail had been thoroughly classicized, and only a romantic wilfulness and freedom of composition recalled the architecture of the Middle Ages. Here are the shell frieze of Blois and the fish-bladder tracery of Orleans, without the Gothic detail which in the French Renaissance is so often found side by side with them. The carving here, equally well executed for its purpose, does not appeal so much to admiration for its execution, for the reason that it is all strictly architectural, and not directly imitative. In design it is for its purpose equally well studied; in scale, indeed, is much better studied, so that the detail, which is often lost in the ineffectual minuteness of the carving in the former case, here takes its place with emphasis. Perhaps in some instances it takes its place with too much emphasis, as in the modelling of the arches of the first floor; while, on the other hand, there is a clear lack of vigor in the brackets which carry the balcony of the third story, and in the treatment of the spiral shaft upon which rests the corbelled turret at the outer angle. But these defects of design seem to be quite deliberate, and it seems, upon the whole, that the building looks as the architect intended it to look, in a more accurate sense than can be said of its competitor. The leading motive of composition in that was the “pyramidization” at the angle. The leading motive of this may be assigned to the development of the floor lines. The perpendicular lines are entirely subordinated
to these—so far subordinated, indeed, that the axial lines of the openings in the lower stories are disregarded in the upper—and the horizontal lines are wrought by modelling and decoration into emphatic belts, graduated in richness from the simple basement course to the very rich and elaborate cornice. We may say here, too, that our admiration grows fainter above this line; for the exaggerated dormers, excessive as dormers and inadequate as gables, are the least successful features of the building, while in their decoration, alone in the building, constructive propriety is abandoned. But the great and simple roof certainly prevents the building from straggling, as its neighbor tends to do, while the angle turrets at its base not only relieve its outline of monotonous heaviness, but are clever expedients for stopping the lines of its angles. Upon the whole, one may say of Mr. Post’s design that it is a thoroughly workmanlike piece of work, and may even find less fault with it than with the more ambitious work of Mr. Hunt; though, indeed, he may ascribe this to his belief that there is less in it to talk about or to think about.
Between either of these and the brown-stone houses which have been built for Mr. William H. Vanderbilt, after the designs of Messrs. Herter, the decorators, a wide architectural gulf is fixed. We found a leading motive in each of the others; but what leading motive, or, indeed, what subordinate motive, of an architectural kind, can be found here? There is indeed no development of lines or of masses, and no organized relation of parts is aimed at. The openings are not grouped or spaced so as to tell the story of the interior, nor so as to bear any reference to each other, nor are the structural features which every building must possess brought out by modelling; nor is the ornament appliedto accentuate the structural features, nor is it designed with reference either to its place or to its function as ornament. The fluted pilasters of the second story seem to be meant, indeed, to re-enforce the angles of the projecting portions of the wall. But this intention is abandoned in the first and in the third stories, in which a belt of carved foliage is run to the angles of the wall, without reference to the lines of the pilasters. This foliage is in workmanship as careful as possible—as careful, indeed, as the carving in either of the architectural works which we have been discussing. Yet its perfection gives no pleasure to the spectator, for the simple reason that it has nothing to do with the building in the walls of which it is cut. Much of the detail is carefully designed, but the absence of a general design makes it ineffective. Except for the refinement of some of this detail, the building would be as vacant of architectural interest as any work of our architectural period of darkness. The Stewart mansion does not interest students of architecture; but the Stewart mansion itself exhibits a nearer approach than these houses to an architectural design, and certainly a coherent design with coarse detail is less depressing, even if it be more irritating, than an entire absence of architectural meaning, with here and there a pretty architectural phrase which in some other context may have meant something. These houses have another misfortune in their very lugubrious color. A vivid piece of painted decoration in the recessed balcony of the nearer is a grateful oasis in the gloomy waste of rubbed sandstone, and some relief to its monotony is also afforded by the gilded railings of the windows at each side of this balcony. But it is to be hoped that courage may be found to let loose a discreet decorator with unlimited goldleaf upon the whole sad fronts. A mode of decorationwhich has been found so effective in the fogs of London might profitably be employed to animate façades which are in no danger of becoming too joyous. It would not be fair to leave these architectural failures, which are in so unpleasant contrast to the encouraging architectural success achieved in the other Vanderbilt houses, without noting one excellent piece of design in the railings which surround them, in which an original, characteristic, and successful treatment of metal has been attained, and which, as works of art, are really of more value than the houses they protect.

THE total length of the bridge is 5989 feet, of which the central span between the towers is 1595 feet 6 inches, the “land spans” from the towers to the anchorages each 930 feet, the approach on the New York side 1562 feet 6 inches, and on the steeper Brooklyn side 971 feet. These dimensions do not make this the longest bridge in the world. But when it was built there was no single span which approached the central span over the East River; and though it has since been exceeded by two spans of the Forth Bridge, in Scotland (1710 feet each, sustained by cantilevers), it remains by far the largest example of a chain-bridge. It is half as long again as Roebling’s Cincinnati Bridge (1057 feet between towers), and nearly twice as long as the same engineer’s Niagara Bridge (821 feet). The span of the ill-fated bridge over the Ohio at Wheeling, which was built in 1848, and blown down in 1854, was 1010 feet. Noteworthy suspension-bridges in Europe are Telford’s, over the Menai Straits (589 feet), finished in 1825; Chaley’s bridge, at Fribourg (870 feet), finished in 1834; and Tierney Clark’s bridge over the Danube at Pesth (670 feet), finished in 1849. The longest spans bridged otherwise than by a roadway hung from cables are the central spans of Stephenson’s Britannia (box girder) Bridge (459 feet), of Eads’s St. Louis Bridge, of steel arches (520 feet), and of the beautiful Washington Bridge, of steel

arches, at New York (510 feet). The largest span of an arch of masonry known to have been built in a bridge (251 feet) was in that built in the fourteenth century, and destroyed by Carmagnola in the fifteenth, which crossed the Adda at Trezzo. The largest now standing (220 feet) is an American work, the arch designed and built by General Meigs to carry the Washington Aqueduct over Cabin John Creek. The second is that of the Grosvenor Bridge at Chester (200 feet), and the third the central arch of London Bridge (152 feet).
The Brooklyn Bridge is thus one of the mechanical wonders of the world, one of the greatest and most characteristic of the monuments of the nineteenth century. Its towers, at least, bid fair to outlast every structure of which they command a view. Everybody recalls Macaulay’s prophecy of the time “when some traveller from New Zealand shall, in the midst of a vast solitude, take his stand upon a broken arch of London Bridge, to sketch the ruins of St. Paul’s.” But when our New-Zealander takes his stand above the saddles that are now ridden by the cables of the bridge, to look over the site of a forsaken city, there will be no ruins of churches—at least, of churches now in being—for him to sketch or see. The web of woven steel that now hangs between the stark masses of the towers may have disappeared, its slender filaments rusted into nothingness under the slow corrosion of the centuries. Its builders and the generation for which they wrought may have been as long forgotten as are now the builders of the Pyramids, whereof the traveller, “as he paceth amazedly those deserts,” asks the Historic Muse “who builded them; and she mumbleth something, but what it is he heareth not.” It is not unimaginable that our future archæologist, looking from one of these towers upon the solitude of a mastless river and a dispeopled land,may have no other means of reconstructing our civilization than that which is furnished him by the tower on which he stands. What will his judgment of us be?
This, or something like this, ought to be a question with every man who builds a structure which is meant to outlast him, whether it be a temple of religion or a work of bare utility like this. It so happens that the work which is likely to be our most durable monument, and to convey some knowledge of us to the most remote posterity, is a work of bare utility; not a shrine, not a fortress, not a palace, but a bridge. This is in itself characteristic of our time. It is true of no other people since the Romans, and of none before. Like the Roman remains, the duration of this work of ours will show that we knew how to build. “A Roman work,” we often hear it said of the bridge, and it is in many ways true. It is far beyond any Roman monument in refinement of mechanical skill. It is Roman in its massiveness and durability. It is Roman, too, in its disregard of art, in resting satisfied with the practical solution of the great problem of its builders, without a sign of that skill which would have explained and emphasized the process of construction at every step, and everywhere, in whole and in part, made the structure tell of the work it was doing. There have been periods in history when this æsthetic purpose would have seemed to the builder of such a monument as much a matter of course, as necessary a part of his work, as the practical purpose which animated the designer of the Brooklyn Bridge. It would have seemed so to the engineer of a bridge in Athens in the second century before our era, or to the engineer of a bridge in Western Europe in the thirteenth century of our era. The utilitarian treatment of our monument is as striking and as characteristic a mark of the period as its utilitarian purpose. It is anoble work of engineering; it is not a work of architecture.
The most strictly scientific of constructors would scarcely take the ground that he did not care how his work looked, when his work was so conspicuous and so durable as the Brooklyn Bridge, and he must be aware that a training in scientific construction alone will not secure an architectural result. It is more probable that he looks upon the current architectural devices as frivolous and irrelevant to the work upon which he is engaged, and consoles himself for his ignorance of them by contempt. Architecture is to him the unintelligent use of building material. Assuredly this view is borne out by a majority of the “architecturesque” buildings that he sees, and he does not lack express authority for it. Whereas the engineer’s definition of good masonry is “the least material to perform a certain duty,” Mr. Fergusson declares that “an architect ought always to allow himself such a margin of strength that he may disregard or play with his construction;” and Mr. Ruskin defines architecture to be the addition to a building of unnecessary features. An engineer has, therefore, some warrant for considering that he is sacrificing to the graces and doing all that can reasonably be expected of him to produce an architectural monument, if in designing the piers of a chain-bridge he employs an unnecessary amount of material and adds unnecessary features. But if we go back to the time when engineers were artists, and study what a modern scientific writer has described as “that paragon of constructive skill, a Pointed cathedral,” we shall find that the architecture and the construction cannot be disjoined. The work of the mediæeval builder in his capacity of artist was to expound, emphasize, and refine upon the work he did in his capacity of constructor, and to develop andheighten its inherent effect. And it is of this kind of skill that the work of the modern engineer, in so far as he is only an engineer, shows no trace.
Reduced to its simplest expression, and as it has actually been used for unknown periods in Asia and in South America, a suspension-bridge consists of two parallel ropes swung from side to side of a ravine, and carrying the platform over which the passenger walks. As the span increases, so that the dip makes the ropes impracticable, the land ends of the ropes are hoisted some distance above the roadway which they carry. If nothing can be found there strong enough to hold them, they are simply passed over, say, forked trees, and the ends made fast to other trees or held down with stones. This is the essential construction of the Brooklyn Bridge. The ropes become four cables sixteen inches thick, of 5541 steel wires; the forked tree becomes a tower 276 feet high, and 8260 square feet in area at the base; the bowlder to hold down the end of the rope becomes a mass of masonry of 60,000 tons’ weight; the shaky platform becomes a great street, 85 feet wide, of five firm roadways. But the man who first carried his rope over the forked tree was the inventor of the arrangement which, developed through all the refinements of modern mechanics, forms the groundwork of the Brooklyn Bridge.
This statement of the germinal idea of a chain-bridge will, perhaps, give a clearer notion of the functions of the several parts of the Brooklyn Bridge than a consideration of the complicated structure in its ultimate evolution, in which these functions are partly lost sight of. But if the structure had been architecturally designed, these things would have been emphasized at every point and in every way. The function of the great “towers,” so called, being merely to hold up the cables, it is plain that three isolated piers would have performed that

function, and the stability of these piers, loaded as they are by the cables, would very possibly have been assured, even if they had been completely detached from each other. But in order at once to stiffen and to load them, so as to make the area of resistance to the force of the wind equal to the whole area of the towers, the openings through which the roadways run are closed aboveby steep pointed arches, and the spandrels of these filled with a wall which rises to the summit of the piers, where a flat coping covers the whole. There is a woful lack of expression in this arrangement. The piers should assert themselves starkly and unmistakably as the bones of the structure, and the wall above the arches be subordinated to a mere filling. It should be distinctly withdrawn from the face of the piers instead of being, as in fact it is, only distinguished from them by their shallow and ineffectual projections. It should be distinctly dropped below their summits instead of rising to the same height, and being included under a common cornice. To see what a difference in effect this very obvious differentiation of parts would have made, glance at the sketch of a suspension-bridge at Minneapolis. This is not, upon the whole, a laudable design, and it contains several survivals of conventional architectural forms meaningless in their present place. But the mere subduing of the archway to a strut between the piers explains—not forcibly, perhaps, nor elegantly, but unmistakably—the main purpose of the structure, and the functional relation of its parts. A drawing of one of the towers of the Brooklyn Bridge without its cables would tell the spectator nothing; the structure itself will tell our New-Zealander nothing of its uses. With its flat top and its level coping, indicating that the whole was meant to be evenly loaded, it would seem to be the base of a missing superstructure rather than what it is.
The flatness of the top alone conceals instead of expressing the structure. It is of the first practical necessity that the great cables should move freely in their saddles, so as always to keep the pressure upon the piers directly vertical, and very ingenious appliances have been employed to attain this end, and to avoid chafing the cables. But the design of the piers themselves
tells us absolutely nothing of all this. The cable simply disappears on one side and reappears on the other, as if it were two separate cables, one on each side, instead of one continuous chain. Look at this section of the top of the tower, and see how an exquisite refinement of mechanical arrangement may coexist with absolute insensibility to the desirableness even of an architectural expression of this arrangement. The architecture of this crowning member of the tower has nothing whatever to do with the purpose for which the structure exists. Is it not perfectly evident that an architectural expression of this mechanical arrangement would require that the line of the summit, instead of this meaningless flat coping, should, to begin with, be a crest of roof, its double slope following the line of the cable which it shelters? Here the very channel through which the cable runs is not designed, but is a mere hole occurring casually, and not by premeditation, in the midst of the mouldings which form the cornice of the tower. This is architectural barbarism.
Other opportunities offered for architectural expression in the towers themselves were in the treatment of the buttresses, in the treatment of the balconies which girdle the tower at the height of the roadway, and in the modelling of the arches. The girth of each of the towers at the water-line is 398 feet. At the roof-course it is 378 feet. The reduction is effected by means of five or six offsets, which withdraw each face of the tower four feet between the bottom and the top, and each end six feet. The counter-forts, eight in all, on the sides of the outer piers and on the faces of all the piers, are mere applied strips, very shallow in proportion to their width, and terminating in the capital-like projections which are casually pierced to receive the cables. It may make, perhaps, no serious difference in the mechanical efficiency of these counter-forts whether their area be narrow and deep or broad and shallow. But an increase of depth in proportion to width would of itself, with its higher lights and sharper shadows, have made forcible masses of what are now ineffectual features. This inherent effect would be very greatly enhanced if the offsets themselves were accentuated by sharp and decisive modelling. As it is, emphasis seems to have been studiously avoided. The offsets are merely long batterings of the wall, which do nothing to separate the piers into related parts with definite transitions, and so to refine the crudity of the masses. To see the difference between a mechanical and a monumental conception of a great structure, compare these towers with the front of Amiens, or of Strasburg, or of Notre Dame of Paris. Of course the designer of a modern bridge must not attempt to reproduce in his work “those misty masses ofmultitudinous pinnacle and diademed tower.” That would be a more fatal fault than the rudeness and crudeness with which we have to charge the design of the towers of the Brooklyn Bridge. The ornament of the cathedrals, so far as it is separable from their structure, has nothing for the designer of the bridge even of suggestion. But to see how masses may be modelled so as to be made to speak, look at the modelled masses of the tower of Amiens, the stark lines of essential structure framing the screen of wall between them, in contrast with the uniform deadness here of buttress and curtain wall; the crisp emphasis of lines of light and hollows of black shade which mark the transitions between parts of structure in the west front of Rheims, in contrast with the lack of emphasis in the offsets of the bridge tower; the spirit of the gargoyled balconies that belt the towers of Notre Dame, and the spiritlessness of the parapeted balconies that encircle the tower of the bridge. And note, too (we are not now speaking of the decoration of the cathedrals), that all this transcendent superiority arises merely from a development and emphasis of the inherent expression of the masses themselves, which in the bridge are left so crude, and in the cathedral towers are refined so far. It need not, and indeed should not, have been carried so far in this architecture of reason and utility as in the architecture of a poetical religion. The mere rudiments of those works would have furnished all the expression that is necessary or desirable here. But these rudiments are wanting. What can we say but that the designer of the cathedral began where the designer of the bridge left off? If our New-Zealander should extend his travels, and come upon these monuments also, what would be his surprise at finding documentary proof that the bridge was built six hundred years after the cathedrals, and that the generation which built the bridge looked backward and downward upon the generation which built the cathedrals as rude and barbarous and unreasoning in comparison with themselves!
What we have said of the towers is true also of the anchorages. The bowlder which the Peruvian rolls upon the end of his rope to hold it down is here a mass of 60,000 tons. Scientifically it is adjusted to its purpose, no doubt, with the most exact nicety. Artistically it is still but a bowlder rolled upon a rope. It would probably be impracticable to exhibit the anchor plate which takes the ultimate strain of this mile and more of cable, though we may be sure that our Greek or our Gothic bridge-builder would not have admitted its impracticability without as exhaustive an investigation as the modern bridge-builder has given to the mechanical aspects of his problem. But it was certainly practicable to indicate the function of the anchorage itself, to build it up in masses which should seem to hold the cable to the earth, or a double arch like—or rather unlike—the double arch of the main tower, turned between piers which should visibly answer the same purpose. Instead of either of these, or of any technical device for the same purpose, the weight above is a crude mass, so far from being adapted to its function in its form, that one has to look with some care to find it from the street below, and to distinguish it from the approaches.
What we have called the balconies at the level of the roadway are not “practical” balconies, since they open from the driveways, and not from the walk, and are not accessible as points of view. The purpose of a projection at this point is to secure as great a breadth as possible for the system of wind-braces under the floor of the bridge. This purpose is attained by the projection, but is only masked by the imitations of balconies, instead of being architecturally expressed, as it might have beenunmistakably expressed, by the bold projection of a granite spur from the angle of the pier.
There are, probably, few arches in the world—certainly there can be none outside of works of modern engineering—of anything like the span, height, thickness, and conspicuousness of those in the bridge towers which are so little effective. Like the brute mass of wall above them, they are impressive only by magnitude. The great depth of the archway is only seen as a matter of mensuration, not felt as a poetical impression, as it would have been if the labors of the constructor had been supplemented by the labors of an artist; if the shallow strips of pier had become real buttresses, and the jamb and arch had been narrowed by emphatic successions of withdrawal, instead of being merely tunnelled through the mass; if the intrados of the arch itself had been accentuated by modelling, instead of being weakened by the actual recession of its voussoirs behind the plane of the wall.
