DEAR SIR:--Your favor, inviting me to a meeting of the friends of Fenimore Cooper, did not reach me till this morning, owing probably to irregularity of the post-office. Otherwise I should have tried to attend the proposed meeting, not only as a friend of Mr. Cooper, but as one among those of his countrymen who consider his memory a national trust for honored preservation. In my opinion of Fenimore Cooper as a novelist he is entitled to one merit to which few if any one of his cotemporary European romance writers can lay claim, to wit, originality. Leatherstocking is an original character, and entirely American, which is probably one of the reasons why Cooper was more appreciated in Continental Europe than even Scott, whose magnificent fancy embellished every thing, but whose genius, I think, originated nothing. And then, in my estimate of Mr. Cooper's superior merits, was manly independence--a rare American virtue. For the less free Englishman or Frenchman, politically, there was a freeness in the expression as well as adoption of his own views of men and things. And a third kindred merit of Cooper was high-minded and gentlemanly abstinence from self-applause. No distinguished or applauded man ever was less apt to talk of himself and his performances. Unlike too many modern poets, novelists, and other writers, apt to become debauchees, drunkards, blackguards and the like (as if, as some think, genius and vice go together), Mr. Cooper was a gentleman remarkable for good plain sense, correct deportment, striking probity and propriety, and withal unostentatiously devout. Not meaning to disparage any one in order by odious comparisons to extol him, I deem his Naval History a more valuable and enduring historical work than many others, both English and American, of contemporaneous publication and much wider dissemination. In short, if the gentlemen whose names I have seen in the public journals with yours, proposing some concentrated eulogium, should determine to appoint a suitable person, with time to prepare it, I believe that Fenimore Cooper may be made the subject of illustration in very many and most striking lights, justly reflecting him, and with excellent influence on his country. I do not recollect, from what I read lately in the newspapers, precisely what you and the other gentlemen associated with you in this proceeding propose to do, or whether any thing is to take place. But if so, whatever and wherever it may be, I beg you to use this answer to your invitation, and any services I can render, as cordial contributions, which I shall be proud and happy to make. I am very respectfully your humble servant, C. J. INGERSOLL.
