Those volumes, then, will supply a general and a very well conceived estimate of immense tracts of the globe, hitherto but little known to the English public. The view is clear, quick, and discriminative. The countries of which it gives us a new knowledge are probably destined to act with great power on our interests, some as the rivals of our commerce, some as the depots of our manufactures, and some as the recipients of that overflow of population which Europe is now pouring out from all her fields on the open wilderness of the world. This spread of emigration to the north is a curious instance of the reflux of the human tide; for, from the north evidently was Europe originally peopled. Japhet was a powerful propeller; and often as he has dwelt in the tents of Shem, he is likely to overwhelm the whole territory of the southern brother once more. The Turk, the Egyptian, the man of Asia Minor, the man of Thrace, will yet be but tribes in that army of the new Xerxes which, pouring from Moscow, and impelled from St Petersburg, will renew the invasions of Genghiz and Tamerlane, and try the civilized strength of the west against the wild courage and countless multitudes of Tartary. Into this strange, but important, and prospectively powerful country, we now follow the traveller. Embarking from Liverpool in the Caledonia, a vessel of 1300 tons and 450 horse power, he was amply prepared to face the perils of the most stormy of all oceans, the Atlantic. The run across lad the usual fortunes of all voyages, and within a week after their departure from _terra firma_ they saw a whale, who saw them with rather more indifference, for he lay lounging on the surface until the steamer had nearly run over him. At last he dived down, and was seen no more. Next day, while there was so little wind, that all their light canvass was set, they saw the phenomenon of a ship under close-reefed topsails. This apparent timidity was laughed at by some of the passengers, but the more experienced guessed that the vessel had come out of a gale, of which they were likely to have a share before long, a conjecture which was soon verified.
