Mr. Cairnes justly denies the common theory that the South has maintained paramount political sway in the Union by a superior capacity for politics. He declares that men whose interests and ideas are concentrated in a very narrow range, on one object, have vast advantage over their intellectual superiors, when the latter pursue no such single course. He might have added that the young Southern gentleman, when not intended for a physician, almost invariably devotes to mere provincial politics and the arts of declamation and debate, all of those intellectual energies which the Northerner applies to business, art, commerce, literature, and other solidly useful occupations. If the Southerner has an inborn superior _talent_ for politics, why is it that, as in the case of British or French statesmen, he never develops the slightest talent for _literature_? So notoriously is this the case, that even the first writers of the South, especially for the press, are generally broken-down Northern literary hacks, or miserable Irish and English refugees. Mr. Cairnes quotes De Bow's _Review_. He might be amazed, could he examine a number of that remarkable periodical, at the quality of the English written by some of the most eminent philosophers, patriots, and politicians of the confederacy! The history of the Slave Power, as set forth in Louisiana, Missouri and its Compromise, the Mexican war, Kansas, the rise of the Republican Party, the Dred Scott decision, the attempt of John Brown, and secession, are given in a masterly manner in this work, and with a miraculous appreciation of truths. Not less vigorous and shrewd is the chapter devoted to the designs of the Slave Power, in which the future capacity of that power to do illimitable mischief is set forth in a manner which will be new even to the great mass of American Republican readers. If we differ with him in his 'Conclusion,' it is that we may be consistent to his earlier position. We do not agree with him when he advocates the giving permission to the South to secede with the Mississippi as their western boundary. Penned up by North and West, and with their ports occupied by us, the South would soon decay. But we rather believe the North, brought to the tremendous trial of a test between aristocracy and republicanism, will yet conquer by destroying slavery and giving the poor whites of the South their rights. But we cannot conclude without expressing the earnest hope that this book will be read, and that thoroughly, by every intelligent American. There is at present a reaction rapidly forming in England in favor of the Federal cause, and we foresee that this extraordinary work--the best summary in existence of our principles, and the most overwhelming stylus-stroke which slavery has ever received--is destined to be of incalculable service to the great cause. Let it circulate by the hundred thousand!--and do you, dear reader, do your part by perusing it, and making its merits known to all.
