Of DR. ANDREE'S great work on _America_, whose commencement we noticed some months since, the fifth, sixth, seventh and eighth parts have just reached us. The German savan continues to justify the high encomiums we passed upon the earlier portions of his work. He has used with the utmost industry and conscientiousness all the best sources of information on every subject he treats. Gallatin, Morton and Squier he frequently quotes as authorities. These four parts are devoted to the conclusion of the essay on the origin and history of the American race. In this he calls attention to the fact that all the developments of American civilization took place on high plain lands and not in the rich vallies of the great rivers--a fact by the way which confirms Mr. Carey's theory of the first settlement and culture of land, though to this Dr. Andree does not refer. He then treats of Canada, New Brunswick, Nova Scotia, the Bermudas and the United States. The leading facts in the geography, history, the sources of population, the political constitution, the geological structure, soil, climate, industry, resources, and prospects of these countries are given with admirable succinctness, thoroughness and justice. As a book of ordinary reference, none could be more convenient or reliable. The most difficult questions are considered with a genuine German cosmopolitan impartiality of judgment. The predominant influence in the formation of the American democratic institutions Dr. Andree considers to be English, or more strictly speaking Teutonic. Other races and nations have contributed to the mass of the people, but only the Teutonic has laid the foundation and built the structure of the state. It is a great blessing in the history of the continent that the French did not succeed in their plans of colonization, for they would everywhere have founded not democratic but feudal institutions. The slavery question he treats more in the interest of the south than in the spirit of the abolitionists, whose course he condemns with considerable plainness of expression. On the mode of finally solving this question, he offers no speculations, but contents himself with showing the great difficulties attending colonization and emancipation upon the soil. The former he thinks impossible, the latter can only produce war between the two races, in which the latter must be exterminated. This mode of viewing this subject we can testify is frequent among well-educated Germans. The statistics relating to the United States, Dr. Andree has collected in a most lucid manner; we do not know where they are better or more conveniently arranged. Products, imports, exports, debt of federal and state governments, taxation, shipping, railroads, canals, schools, are all given; nothing escapes the vigilance of this most exemplary ethnographer. His style is no less clear and vivid in these four parts than in those preceding. The remainder will follow regularly. The work may be found at
