In 1811, Cooper, having resigned his post as midshipman, began the year by marrying Miss Delaney, sister of the present bishop; of the diocese of Western New York, and entered upon a domestic life happily passed to its close. He went to live at Mamaroneck, in the county of Westchester, and while here he wrote and published the first of his novels, entitled Precaution. Concerning the occasion of writing this work, it is related, that once, as he was reading an English novel to Mrs. Cooper, who has, within a short time past, been laid in the grave beside her illustrious husband, and of whom we may now say, that her goodness was no less eminent than his genius, he suddenly laid down the book, and said, "I believe I could write a better myself." Almost immediately he composed a chapter of a projected work of fiction, and read it to the same friendly judge, who encouraged him to finish it, and when it was completed, suggested its publication. Of this he had at the time no intention, but he was at length induced to submit the manuscript to the examination of the late Charles Wilkes, of this city, in whose literary opinions he had great confidence. Mr. Wilkes advised that it should be published, and to these circumstances we owe it that Cooper became an author. I confess I have merely dipped into this work. The experiment was made with the first edition, deformed by a strange punctuation--a profusion of commas, and other pauses, which puzzled and repelled me. Its author, many years afterwards, revised and republished it, correcting this fault, and some faults of style also, so that to a casual inspection it appeared almost another work. It was a professed delineation of English manners, though the author had then seen nothing of English society. It had, however, the honor of being adopted by the country whose manners it described, and, being early republished in Great Britain, passed from the first for an English novel. I am not unwilling to believe what is said of it, that it contained a promise of the powers which its author afterwards put forth.
