held, and would have modified or destroyed any prejudices entertained towards him by others, if any such existed. Up to this period in his public career, Cooper had certainly not done anything to undermine his popularity. He now entered upon a line of conduct which it is charity to call blundering. He began, or at any rate pursued, a controversy, in which nothing was to be gained and everything to be risked, if not actually lost. He not only set himself to defend a course that needed no defense, he replied to attacks, real or imaginary, which could only be raised into importance by receiving from him notice. These attacks were a criticism on "The Bravo" which had appeared in the "New York American;" a criticism on his later writings which was found in the columns of the "New York Commercial Advertiser;" and an (p. 129) editorial article in the "New York Courier and Enquirer." He could not have done a more foolish thing. He knew perfectly well that no writer could be written down save by himself. He has quoted the very remark. But a hundred similar sayings, condensing in a line the wisdom of ages, could never have kept him quiet when an attack was made upon himself. A popular writer has always immense odds in his favor in any controversy he may have with inferior men. He is ordinarily sure of the verdict of posterity, for his is likely to be the only side that will reach its ears. Even during his own time there will always be a large body of admirers who will defend him with more fervor, and advocate his cause with more effect than he has it in his own power to do. But it can and will be done only in the case that he does little or nothing himself. If Cooper had lost any ground in the estimation of the public, all he had to do, in order to regain it, was to remain quiet. The one thing that Cooper could not do was to remain quiet. He determined to set himself right before his countrymen. He speedily had full opportunity to ascertain the results that are pretty sure to follow experiments of this kind.
