"Greater variety in the mouldings of doors and windows, and in the designs of porticoes, might easily be obtained, with an infinite gain of grace to the city. The Broadway Theatre illustrates this, for it is certainly one of the most impressive buildings upon that street. The question, it must be remembered, is not one of art, so much as of picturesqueness and effect. The galleries and balconies, &c., are only a subterfuge. If an edifice is intrinsically beautiful and well-proportioned, it claims no such accessories, as Stewart's building, which, although a simple square mass, yet from the admirable proportion, rather than the material, is as stately and imposing as many a foreign palace. But where there is no regard--as is the usual case--to the dignity or propriety of form, there we must take advantage of an alleviation, and obtain lightness, gayety, and variety as we best can. "There is, however, one point peculiar to American, or more properly to New-York building, which calls for the determined and constant censure of every man who values human life. We mean the flimsy style of building arising from the frenzied haste with which we do every thing. This has long been our reproach. Scarcely a year passes that we do not record some disaster of this kind, often involving a melancholy waste of life. '_Is it strong?_' is a question constantly asked of a new building, and a question which, in any civilized community, it should be as unnecessary to ask, as whether the public wells are poisoned. "We know many who will not pass under buildings now going up or recently erected. A friend walked down Broadway one morning, while a building was in course of erection on the site of the present Waverly House, and returning in the afternoon found that it had all tumbled down. Our readers have not forgotten the frightful fall of a block in Twenty-first street last spring. One is curious to know if nothing is ever to be done--if the city means to take no security for the lives of the citizens in this matter. It would be very easy to prevent this flimsy building, and even were it very difficult it should be effectually done. This, too, is a matter in which every citizen is interested. "Stores and Warehouses have their own proprieties. Warehouses properly avoid even the _appearance_ of lightness. They are devoted to heavy storage. No life, save of bales and boxes,--and not of the contents of bales and boxes--is associated with them. Security is the first and only thing we demand of them, provided the structures are not painfully disproportioned. So with Prisons. In fact, in architecture, the ornament must depend upon the use, must be developed from the use. For the same reason that balconies become a dwelling-house they disfigure a warehouse. Stores again should partake, in their appearance, of the intrinsic character and associations of shops. When shop-keeping becomes royal, it should be royally housed, as in Stewart's building.
