Mount Welcome, August 6, 1858.

J. Jay Smith, Esq.: - As you are fond of giving good information to your horticultural readers, and extend to us a great deal that is excellent, perhaps you would be willing to take a little in return, especially when it comes from an old friend. I always read your visits to country places with interest. I like to know what is going on around our larger cities, and to hear of the circulation of the wealth amassed by commerce into the rural districts. The embellishment of our noble country, by the hand of taste, has been too long delayed, and now that it has been commenced with such encouraging prospects, I feel grateful to those who, like Downing and yourself, have zealously urged on and directed the spirit of improvement.

We are doing something here, around Cincinnati in the way of rural embellishment, and the suggestion I sat down to make is, that you make a visit to the Queen City of the West. We have some reputation abroad of the rapid growth of our population, and as a mart for some of the great staples of agriculture. The flavor of our hams and the fame of our Sparkling and Dry Catawba are understood abroad, but it is not so well known that our neighborhood abounds in the most attractive and romantic rural scenery. We have a delightful country about us - a region of hill and dale, of amazing fertility; and, now that the great forests have been opened, and the lovely valleys exposed to the eye, with their broad fields of wheat, and corn, and grass, the tasteful visitor will find landscapes here of unsurpassed beauty.

Within a few years past, the desire for country residences has become quite prevalent among our citizens, and many a delightful villa has grown up in consequence. Some occupy them during the whole year, riding in and out to their business, morning and evening, and finding both health and domestic comfort from the arrangement; while others go to the country only in the summer, and return in the winter to the enjoyment of coal-dust and evening parties. The country has thus become highly improved for several miles in every direction, and there can now scarcely be found a city in our land so surrounded by beautiful rides and embellished rural scenery.

We owe much of this taste to our Horticultural Society, which has been conducted with great zeal, and embraces among its members a great deal of practical knowledge, and no small amount of science and taste; and quite as much do we owe to the example, writings and liberal expenditures of our venerable and excellent citizen, Nicholas Longworth.

If you will ride with me to Walnut Hills, I will show you some places worth looking at, and from the river hills some noble views; and here are some of the nurseries from which our suburban cottages are becoming embowered with shrubs and flowers. Then I would take you to Clifton, which we think quite equal to anything of the kind anywhere. This is a suburban district, commencing just beyond the streets after you rise the hills out of the city, and embraces a most beautiful drive of several miles, over a charming country, ornamented by noble country-seats. Here is your correspondent, Robert Buchanan, on a splendid hill, with a fine prospect and a successful vineyard, of which you have heard, and from which we have all tasted such choice Dry Catawba wine. He would like to take by the hand such a man as yourself.

The residence of R. B. Bowler is a magnificent affair. Here the hill overlooks a broad valley, studded with cultivated fields, villas and various beauty-spots. The house is on a grand scale, furnished and surrounded with a lavish expenditure, and the whole establishment is princely. Not less beautiful as to locality, but of far less pretension, is the more humble residence of Bishop M'llvaine, combining good taste and comfort The fine mansion of Griffin Taylor, Esq., is beautifully surrounded, and commands a noble prospect; and the excellent man and eminent jurist, Mr. Justice M'Lean, of the Supreme Court of the United States, with his admirable lady, has a fine spacious house here, on a commanding eminence.

You will find me in a different locality, not less attractive by nature, but, as yet, wholly unembellished by the hand of wealth - perched on the brow of a hill, overlooking the picturesque valley of the Little Miami. Nature has here spread, with a lavish hand, her most bounteous gifts, and you might travel far without finding a valley so richly adorned, through its whole length, with romantic scenery, rich verdure and gigantic natural productions. It is traversed by a railroad, whose directors are so squeamish as not to authorize the slaughter or maiming of human beings, and whose trains enjoy the distinction of being, so far, guiltless of the blood of mankind. I have a snug cottage here, to which no one would be more cordially welcome than the editor of the Horticulturist. We are half a mile from Loveland, where the Little Miami Railroad has a station, and where the Marietta and Cincinnati Railroad connects with the former road. You can get to us over the Pennsylvania Central, or over the Baltimore and Ohio Railroad, and will be sure of safe and agreeable traveling either way.
