In a little hamlet of five or fifteen hundred inhabitants, great buildings are out of place. In a city like ours, every thing should be in keeping, and the predominant principle should be the gigantesque. If the lot-holders from Bowling Green to the New Park would but consider the matter, with intelligent reference not only to the glory of the city but to their own profit; if each separate square were built as if it were one edifice (as, without any blending of property, it might be very easily), though these squares were all of plain brick, and no more costly than the well-known row of stores in William-street, what an imposing spectacle they would present! But if one block were like the Astor House, the next like Stewart's (except only the Reade street front), the next a row of free-stone, the next one of brick, the next one of granite,—here a Gothic, there a Byzantine, then a Corinthian, then, if you please, as plain a front as that of the New-York Hotel—with here and there a church, library, lyceum, or art gallery, of a style less suitable for shops or dwellings,—and there would be nothing in the world to compare with Broadway. But this running of democracy into the ground, this whim of every vulgar fellow who owns a front of twenty feet, that he must illustrate his independence by building on it in his own peculiar way, is baulking Providence, and for the full cost of magnificence confining us to tricksy meanness. Two or three years ago rose the chaste and simple front of 349 Broadway, in a row of decayed brick shops, which, it was hoped would give place to an entire range in imitation of the initial structure. But since then, the owner of a couple of adjoining lots—a Connecticut man probably—has caused to be put up two stores of a different style, not of half the value of continuations of the less expensive edifice which they join. If instead of this patchwork, now planted here for half a century, there had been an extension of uniform stores from corner to corner—though either Beck's or the building we have mentioned had been the model—the single splendid edifice would have been a pride and boast of the city, and the separate stores would have been of much greater value than the best can be now. It is as revolting (and much more vexatious, for its publicity) as the worst case of Saxon and Congo amalgamation. A magnificent pile has been erected in Wall-street on the corner west of the Exchange; but some person, ignorant, it is to be hoped for his soul's sake, of the true obligations of morality applicable in the case, has built, at the same time, at the same cost, of the same height, and without any conceivable justifying reason, an utterly incongruous basket of offices, as if for the special purpose of vexing the eyes of men who have instincts of decency.

THOMPSON'S SALOON.

The imposing edifice on the corner of Broadway and White-street, of which a view is presented on a preceding page, is one of the improvements of the city made during the last year. In the great carpet-house of Peterson & Humphrey are offered the productions of the best looms in the world, in a variety and profusion probably unequalled elsewhere in America. The principal saloon is like a street, and it is almost always thronged with people.

Not far from the store of Peterson & Humphrey—at 359 Broadway—is the new and beautiful building erected by the well-known confectioners, Thompson & Son. This was opened to the public but a few weeks ago, and it is the most splendid establishment of the kind in America. The several sales during the last three quarters of a century of the ground upon which it is built, illustrate the rapid increase of value in real estate in this city during that period. The lot formed a part of the De Peyster farm, and was called pasture ground. On the death of Major De Peyster, the farm was divided, and this lot, then thirty-two feet wide, was on the 13th of December, 1784, sold for £100 New-York currency; in 1789 it was sold for £150; in 1805 for $1500; in 1820 for $4000; in 1825 for $11,000; and in 1850 it was bought by Mr. Thompson for $60,000, and he has expended $50,000 in the erection of the building with which it is now occupied, and which is twenty-eight feet wide, one hundred and ninety feet deep, and sixty-two feet high. It is built in a very rich style, of Paterson stone, similar to that used in Trinity church. The architects were Field and Correja, and the decorations in fresco are by Rossini. Mr. Thompson, senior, has been a quarter of a century in the business for which he has erected this new edifice, and in which he has accumulated his fortune. In 1820 there were but one or two houses of the kind in New-York, and these were of limited capacity and in every way inferior to Taylor's, Weller's, or Thompson's, of the present day. These are among the most luxurious and comfortable resorts for ladies and gentlemen who visit the city but for a part of a day, or who have not time or inclination to go to houses in distant parts of the town, to lunch or dine, or for those who come down Broadway to do shopping, and need a resting place, or enjoy an exchange for gossip.

PRINCIPAL SALOON AT THOMPSON'S.

The next of the Palaces of Trade recently erected in the city, for which we have now room for any description, is the great silk house of the well-known merchants, Bowen & McNamee, constituting one of the most attractive features of the lower part of Broadway. It is built of white marble, and the style of architecture is Elizabethan, and peculiarly elaborate and effective. The building is thirty-seven and a half feet wide, one hundred and forty-seven deep, and four stories high; and each story consists of a single unbroken hall, lined with the richest English, German, French, Italian and Indian goods. The architect was Mr. Joseph C. Wells, and his plans were used in all the minutest details of ornament and furniture. It is regarded, we believe, as the greatest triumph of its kind of which our commercial metropolis has to boast; indeed in magnificence of design, beauty of execution, and perfect adaptation to its purposes, there is nothing superior to it, probably, among the buildings devoted to trade in all the world.

It was said by Jefferson that the genius of Architecture would never make her abode in America; but the new edifices in New-York, of which we have described some prominent specimens, may lead others to a different conclusion. And we are of opinion that the progress of this country, in the last quarter of a century, has been less conspicuous in any thing else than in this noble art, little as it is now understood, much as it is still disregarded. In some recent speculations on the subject, the Tribune observes:

"There is no American architecture, unless the Lowell factories may be regarded as such. Our churches are small and imperfect imitations of a miscellaneous Gothic, and our exchanges, colleges, lyceums, banks and custom-houses affect the Greek, with as much propriety as our merchants, professors and clerks would indue themselves with the Athenian costume. There is no hope of the churches and banks. They are nothing if not Gothic and Grecian. We shall not discuss the probable character of our architecture. It is clear that New-York will build brick houses, and in blocks. But beauty costs no more than ugliness, and although every man has the right to build a house of that appearance which best pleases himself, yet every citizen is bound to have at heart the beauty of the city. He cannot escape it. His pride compels it; and therefore every man who builds a house ought to consult, to some extent, the general effect of his building, and as he would not paint it blue or black, he should no less consider its form than its color.
