I was sitting with my 400 paged guide-book before me, and looking down upon the moving mass, when my attention was called to a small group of gentlemen standing near the statue of Shakspere, one of whom wore a white coat and hat, and had flaxen hair, and trousers rather short in the legs. The lady by my side, and who had called my attention to the group, asked if I could tell what country this odd-looking gentleman was from? Not wishing to run the risk of a mistake, I was about declining to venture an opinion, when the reflection of the sun against a mirror, on the opposite side, threw a brilliant light upon the group, and especially on the face of the gentleman in the white coat, and I immediately recognized under the brim of the white hat, the features of Horace Greeley, Esq., of the New York "Tribune." His general appearance was as much out of the English style as that of the Turk whom I had seen but a moment before--in his bag-like trousers, shuffling along in his slippers. But oddness in dress, is one of the characteristics of the Great Exhibition. Among the many things in the Crystal Palace, there are some which receive greater attention than others, around which may always be seen large groups of the visitors. The first of these is the Koh-i-noor, the "Mountain of Light." This is the largest and most valuable diamond in the world, said to be worth L2,000,000 sterling. It is indeed a great source of attraction to those who go to the Exhibition for the first time, but it is doubtful whether it obtains such admiration afterwards. We saw more than one spectator turn away with the idea that after all it was only a piece of glass. After some jamming, I got a look at the precious jewel, and although in a brass-grated cage, strong enough to hold a lion, I found it to be no larger than the third of a hen's egg. Two policemen remain by its side day and night. The finest thing in the Exhibition, is the "Veiled Vestal," a statue of a woman carved in marble, with a veil over her face, and so neatly done, that it looks as if it had been thrown over after it was finished. The Exhibition presents many things which appeal to the eye and touch the heart, and altogether, it is so decorated and furnished, as to excite the dullest mind, and satisfy the most fastidious. England has contributed the most useful and substantial articles; France, the most beautiful; while Russia, Turkey, and the West Indies, seem to vie with each other in richness. China and Persia are not behind. Austria has also contributed a rich and beautiful stock. Sweden, Norway, Denmark, and the smaller states of Europe, have all tried to outdo themselves in sending goods to the World's Fair. In Machinery, England has no competitor. In Art, France is almost alone in the Exhibition, setting aside England.
