It is to be sincerely hoped that the American public, in its detestation of the ungenerous, narrow-minded, and inconsistent conduct of the majority of Englishmen toward the Federal Union since the present war began, will not lose sight of the fact that, here and there in Great Britain, men of superior intelligence and information have labored strenuously to make the truth known, and to vindicate our cause. Amid a mob of ignorant and furious foes of freedom, France has seen a Gasparin rise calm and great in superior knowledge, declaring incontrovertible truths; and in like manner, the English press has given the views of Stewart Mill and Professor Cairnes to their public, at a time when it seemed as if falsehood had completely triumphed. In 'The Slave Power,' the latest work by this last-named writer, we have indeed such a searching analysis of the present American crisis, and find the history of the entire difficulty set forth so fully, yet with such remarkable conciseness, that we cannot suppress a feeling of astonishment that a country which has slandered us so cruelly should, at the same time, have given to the world by far the best vindication of our cause which has as yet appeared. For it is no undue praise to say, that in this book we have the completest defence of the Federal cause and the most effective onslaught on the Slave Power which any writer has thus far placed on record; and we cordially agree with the vigorous reviewer of the _Westminster_, in believing that a work more needed could scarcely have been produced at the present time, 'since,' as he adds, 'it contains more than enough to give a new turn to English feeling on the subject, if those who guide and sway public opinion were ever likely to reconsider a question on which they have so deeply committed themselves.' 'The Slave Power,' it is true, contains little which has not, at one time or another, been brought before the mind of the well-informed American republican; yet it is precisely in this that its chief merit consists, since it is not by idle oratory and fine writing, but by _facts_ and the plain truth, that we can be best vindicated. Englishmen are grossly ignorant of the true causes of this struggle, or of the principles involved--a matter little to be marvelled at, when we find almost a majority of professed Federal Americans, under the name of Democrats, cheerfully admitting that their confederate foes are quite in the right as far as the _main_ cause of the difficulty is concerned. For all such men, a clear exposition of facts, logically set forth, cannot be other than a real blessing; since their amiability to the South, when not based on traitorous and selfish interests, means simply nothing more nor less than ignorance--and that of a kind which is little less than criminal, let the guilt rest where it may.
