Mr. Froude announced that his object in coming to America was to enlighten the American public as to the true nature of Irish discontent, in such manner that American opinion, acting on Irish opinion, would reconcile the Irish to the English connection, and turn their attention to practical remedies for whatever was wrong in their condition--American opinion being now, in Irish eyes, the court of last resort in all political controversies. It is casting no reflection on the historical or literary value of his lectures to say that Mr. Froude, in proposing to himself any such undertaking, fell into error as to the kind of audience he was likely to command, and as to the nature of the impression he was likely to make. The class of persons who listen to him is one of great intelligence and respectability, but it is a class to which the Irish are not in the habit of listening, and which has already formed as unfavorable opinions about the political character of the Irish as Mr. Froude could wish. He will be surrounded during his whole tour by a public to whose utterances the Irish pay no more attention than to the preachings of Mr. Newdegate or Mr. Whalley, and who have long ago reached, from their observation of the influence of the Irish immigration on American politics, the very conclusions for which Mr. Froude proposes to furnish historical justification. In short, he is addressing people who have either already made up their minds, or whose minds have no value for the purpose of his mission. On the other hand, he will not reach at all the political class which panders to Irish hatred of England, and, if he does reach it, he will produce no effect on it. Not one speech the less will be uttered, or article the less written, in encouragement of Fenianism in consequence of anything he may say. Indeed, the idea that the Bankses will be more careful in their Congressional reports, or the Coxes or Mortons in their political harangues, either after or before election, in consequence of Mr. Froude's demonstration of the groundlessness of Fenian complaints, is one which to "the men inside politics" must be very amusing.
