Mercedes of Castile, published near the close of the same year, has none of the stronger characteristics of Cooper's genius; but in the Deerslayer, which appeared in 1841, another of his Leatherstocking tales, he gave us a work rivalling the Pathfinder. Leatherstocking is brought before us in his early youth, in the first exercise of that keen sagacity which is blended so harmoniously with a simple and ingenuous goodness. The two daughters of the retired freebooter dwelling on the Otsego lake, inspire scarcely less interest than the principal personage; Judith, in the pride of her beauty and intellect, her good impulses contending with a fatal love of admiration, holding us fascinated with a constant interest in her fate, which, with consummate skill, we are permitted rather to conjecture than to know; and Hetty, scarcely less beautiful in person, weak-minded, but wise in the midst, of that weakness beyond the wisdom of the loftiest intellect, through the power of conscience and religion. The character of Hetty would have been a hazardous experiment in feebler hands, but in his it was admirably successful. The Two Admirals and Wing-and-Wing were given to the public in 1842, both of them taking a high rank among Cooper's sea-tales. The first of these is a sort of naval epic in prose; the flight and chase of armed vessels hold us in breathless suspense, and the sea-fights are described with a terrible power. In the later sea-tales of Cooper, it seems to me that the mastery with which he makes his grand processions of events pass before the mind's eye is even greater than in his earlier. The next year he published the Wyandotte or Hutted Knoll, one of his beautiful romances of the woods, and in 1844 two more of his sea-stories, Afloat and Ashore and Miles Wallingfordits sequel. The long series of his nautical tales was closed by Jack Tier or the Florida Reef, published in 1848, when Cooper was in his sixtieth year, and it is as full of spirit, energy, invention, life-like presentation of objects and events-- The vision and the faculty divine-- as anything he has written. Let me pause here to say that Cooper, though not a manufacturer of verse, was in the highest sense of the word a poet; his imagination wrought nobly and grandly, and imposed its creations on the mind of the reader for realities. With him there was no withering, or decline, or disuse of the poetic faculty; as he stepped downwards from the zenith of life, no shadow or chill came over it; it was like the year of some genial climates, a perpetual season of verdure, bloom, and fruitfulness. As these works came out, I was rejoiced to see that he was unspoiled by the controversies in which he had allowed, himself to become engaged; that they had not given to these better expressions of his genius, any tinge of misanthropy, or appearance of contracting and closing sympathies any trace of an interest in his fellow-beings less large and free than in his earlier works.
