The Transept is the heart of the Exhibition, to which all currents converge, from which all expeditions, whether of criticism or discovery, take their departure. Here abound Marble Statues, gigantic Brazen Gates, and other works of Art; while around it are located the fabrics of Turkey and of China, of Australia, and of British America, which are as interesting and instructive in their rudeness and clumsiness as others in their grace and perfection. You could hardly realize without seeing them what wretched contrivances for Candlesticks, Culinary Utensils, Locks and Keys, etc., etc., are still slowly, toilsomely fabricated in Turkey, in Barbary, and in other half-civilized countries. A decent knowledge of the Useful Arts is yet confined to a few nations, and is imperfectly diffused even in these. And here, too, is sad Italy, not allowed to compete in her own name, but sending feeble and timid contributions, as “Sardinia,” “Tuscany,” “Rome,” etc., nothing being allowed to come from Naples. The Roman States, in the heart of ancient Civilization, with Three Millions of People yet, fill half-a-page of the Catalogue, or about one-seventeenth of the space required by the more distant United States; while the beautiful Statuary of the School of Milan, including the Veiled Vestal, one of the most original and admirable works in the Exhibition, is set down to the credit of _Austria_! There is a debtor as well as creditor side to that Austro-Italian account, and settlement cannot be refused forever. Great Britain and her Colonies engross the entire Western half of the Exhibition, and fill it creditably. In the Fine Arts, properly so called, she has probably less than a fourth of what is contributed; but in Iron and its multiform products she has far more than all the World beside. In Steam Engines and Force-Pumps, Looms and Anvils, Ores and Castings, Buttons, Steel-Pens, etc., all the rest combined could not compare with her. I doubt if the world ever before saw so complete and instructive a collection of Ores and Minerals as are here brought together, or that Geology was ever studied under auspices more favorable than this collection would afford. Nearly every metal known to man may here be seen, first as ore, and then in every stage up to that of perfect adaptation to our various human needs. So in the department of Machinery. I think no collection so varied and complete of Looms, Presses, Mills, Pumps, Engines, etc., etc., was ever before grouped under one roof.
