The performance now before us is written in that straightforward practical style which may be best characterized by the statement that "He had something to say, _and he said it_." That it is impartial is not its least merit. A foreigner, it is true, may occasionally be found who passes unprejudiced judgments on another country, but that any one still retaining home-born sympathies and feelings with his native land should do so is a wonder. And we deem it a creditable thing in this work, that where he is called upon to describe any calling, trade, or profession, he is not afraid to say boldly--In this calling the German cannot succeed--in that, he is unapt--in a third, the American surpasses him; while, on the other hand, he amply encourages the emigrant as regards occupations for which he is qualified. Many writers of such books have cast a _couleur de rose_ light over every thing (well knowing that by such means their books would be more saleable), and induced industrious men, following callings unheard of in this country, to emigrate, in the absurd hope of finding more constant and better paid employment here than at home. An intelligent American, who would not cross the Atlantic, or hardly ascend in a balloon, without previously _calculating_ the time and chances of arrival or descent, and who certainly would do neither without first informing himself as to every imaginable particular of his ultimate destination, can hardly conceive the vast necessity of such books. He would, by every means, gather information from those who had visited in person the destined land. Not so the common German emigrant. Thousands embark in the belief that New-York is some mysterious golden-glowing Indian city, surrounded by orange groves and palm-trees. In the village of Weinsberg, in Suabia, several years since, a well-educated student was overheard to remark of some peasants, "Tell them that in your country the people have two heads, and they'll believe you." Let us now, by extracts, give our readers an idea of the manner in which Mr. Von Ross describes the land of his birth to the land of his adoption. The first item of interest is his sketches of the respective characteristics of the Yankee and Southerner.
