There still remained a peculiar feature of the Fair, which I had not yet seen. This is the subterranean network of sewerage, which reproduces, in massive masonry, the streets on the surface. Without it, the annual city of two months would become uninhabitable. The peninsula between the two rivers being low and marshy,--frequently overflowed during the spring freshets,--pestilence would soon be bred from the immense concourse of people: hence a system of _cloacae_, almost rivalling those of ancient Rome. At each street-corner there are wells containing spiral staircases, by which one can descend to the spacious subterranean passages, and there walk for miles under arches of hewn stone, lighted and aired by shafts at regular intervals. In St. Petersburg you are told that more than half the cost of the city is under the surface of the earth; at Nijni-Novgorod the statement is certainly true. Peter the Great at one time designed establishing his capital here. Could he have foreseen the existence of railroads, he would certainly have done so. Nijni-Novgorod is now nearer to Berlin than the Russian frontier was fifty years ago. St. Petersburg is an accidental city; Nature and the destiny of the empire are both opposed to its existence; and a time will come when its long lines of palaces shall be deserted for some new capital, in a locality at once more southern and more central. Another walk through the streets of the Fair enabled me to analyze the first confused impression, and separate the motley throng of life into its several elements. I shall not attempt, however, to catch and paint its ever-changing, fluctuating character. Our limited visit allowed us to see only the more central and crowded streets. Outside of these, for miles, extend suburbs of iron, of furs, wool, and other coarser products, brought together from the Ural, from the forests towards the Polar Ocean, and from the vast extent of Siberia. Here, from morning till night, the beloved _kvass_ flows in rivers, the strong stream of _shchi_ (cabbage-soup) sends up its perpetual incense, and the samovar of cheap tea is never empty. Here, although important interests are represented, the intercourse between buyers and sellers is less grave and methodical than in the bazaar. There are jokes, laughter, songs, and a constant play of that repartee in which even the serfs are masters. Here, too, jugglers and mountebanks of all sorts ply their trade; gypsies sing, dance, and tell fortunes; and other vocations, less respectable than these, flourish vigorously. For, whether the visitor be an Ostiak from the Polar Circle, an Uzbek from the Upper Oxus, a Crim-Tartar or Nogai, a Georgian from Tiflis, a Mongolian from the Land of Grass, a Persian from Ispahan, a Jew from Hamburg, a Frenchman from Lyons, a Tyrolese, Swiss, Bohemian, or an Anglo-Saxon from either side of the Atlantic, he meets his fellow-visitors to the Great Fair on the
