and then chokes its interstices with soot; cities which are mere crowded masses of store, and warehouse, and counter, and are therefore to the rest of the world what the larder and cellar are to a private house; cities in which the object of men is not life, but labor; and in which all chief magnitude of edifice is to inclose machinery; cities in which the streets are not the avenues for the passing and procession of a happy people, but the drains for the discharge of a tormented mob, in which the only object in reaching any spot is to be transferred to another; in which existence becomes mere transition, and every creature is only one atom in a drift of human dust, and current of interchanging particles, circulating here by tunnels underground, and there by tubes in the air; for a city, or cities, such as this no architecture is possible--nay, no desire of it is possible to their inhabitants. 278. One of the most singular proofs of the vanity of all hope that conditions of art may be combined with the occupations of such a city, has been given lately in the design of the new iron bridge over the Thames at Blackfriars. Distinct attempt has been there made to obtain architectural effect on a grand scale. Nor was there anything in the nature of the work to prevent such an effort being successful. It is not edifices, being of iron, or of glass, or thrown into new forms, demanded by new purposes, which need hinder its being beautiful. But it is the absence of all desire of beauty, of all joy in fancy, and of all freedom in thought. If a Greek, or Egyptian, or Gothic architect had been required to design such a bridge, he would have looked instantly at the main conditions of its structure, and dwelt on them with the delight of imagination. He would have seen that the main thing to be done was to hold a horizontal group of iron rods steadily and straight over stone piers. Then he would have said to himself (or felt without saying), "It is this holding,--this grasp,--this securing tenor of a thing which might be shaken, so that it cannot be shaken, on which I have to insist." And he would have put some life into those iron tenons. As a Greek put human life into his pillars and produced the caryatid; and an Egyptian lotus life into his pillars and produced the lily capital: so here, either of them would have put some gigantic or some angelic life into those colossal sockets. He would perhaps have put vast winged statues of bronze, folding their wings, and grasping the iron rails with their hands; or monstrous eagles, or serpents holding with claw or coil, or strong four-footed animals couchant, holding with the paw, or in fierce action, holding with teeth. Thousands of grotesque or of lovely thoughts would have risen before him, and the bronze forms, animal or human, would have signified, either in symbol or in legend, whatever might be gracefully told respecting the purposes of the work and the districts to which it conducted. Whereas, now, the entire
