Behold the Fifth Avenue of Cincinnati! It is not merely the pleasant street of villas and gardens along the brow of the hill, though that is part of it. Mount to the cupola of the Mount Auburn Young Ladies' School, which stands near the highest point, and look out over a sea of beautifully formed, umbrageous hills, steep enough to be picturesque, but not too steep to be convenient, and observe that upon each summit, as far as the eye can reach, is an elegant cottage or mansion, or cluster of tasteful villas, surrounded by groves, gardens, and lawns. _This_ is Cincinnati's Fifth Avenue. Here reside the families enriched by the industry of the low, smoky town. Here, upon these enchanting hills, and in these inviting valleys, will finally gather the greater part of the population, leaving the city to its smoke and heat when the labors of the day are done. As far as we have seen or read, no inland city in the world surpasses Cincinnati in the beauty of its environs. They present as perfect a combination of the picturesque and the accessible as can anywhere be found; and there are still the primeval forests, and the virgin soil, to favor the plans of the artist in "capabilities." The Duke of Newcastle's party, one of whom was the Prince of Wales, were not flattering their entertainers when they pronounced the suburbs of Cincinnati the finest they had anywhere seen. The groups of villas, each upon its little hill, are the _cities_ before mentioned, five of which are within sight of the young ladies who attend the liberally conducted seminary of Mount Auburn. The stranger is continually astonished at the magnitude and costliness of these residences. Our impression was, that they are not inferior, either in number or in elegance, to those of Staten Island or Jamaica Plain; while a few of them, we presume, are unequalled in America. The residence of Mr. Probasco is the most famous of these. Externally, it is a rather plain-looking stone house, something between a cottage and a mansion; but the interior is highly interesting, as showing how much money to the square inch can be spent in the decoration of a house, provided the proprietor has unlimited resources and gives himself up to the work. For seven long years, we were informed, the owner of this house toiled at his experiment. Every room was a separate study. All the walls are wainscoted with oak, most exquisitely carved and polished, and the ceilings were painted by artists brought from Italy. It is impossible to conceive an interior more inviting, elegant, and harmonious than this. Thirty years ago the proprietor of this beautiful abode was an errand-boy in the establishment of which he was afterwards the head; and when we had the impudence to look into his house, he was absent in Europe in quest of health! The moral is obvious even here at the end of this poor paragraph, but it was staggering upon the spot. How absurd to be sick, owning such a house! How ridiculous the idea of dying in it!
