The _dramatic_ romance of Scott and Cooper is now preferred to all others, and has caused Brown's novels to be cast aside. Cooper's rise to fame was as rapid as it was deserved. He had been for some years an officer in the American Navy, where he acquired a knowledge of all the minutiæ of nautical life, which was of great service to him in the composition of some of his tales. These are justly considered as his best. They display a perfect intimacy with sea life, and his characters, incidents and sentiments are such as belong to the "mountain wave," and are always in admirable keeping. His dialogues, though sometimes tedious and unnecessarily prolonged are on the whole dramatic, and serve not only to develope character but to excite the interest of the reader. His descriptions, though at times graphic and striking, are rather too minute for effect. The unities of time and action are well preserved, and his plots, though very simple in their construction, are usually wrought up with great power, and often produce the most intense and thrilling interest. Of his female characters, generally two in number, but little can be said; they are Siamese twins, but with different dispositions and styles of beauty, and play the respective parts assigned to them in the drama with proper decency and effect. His sketches of American scenery and his delineations of savage life and character are admirable. There is in the former perhaps too much detail, and in the latter too high coloring for nature; but they are unequalled, and display the vigor of Cooper's genius and the strength of his conceptions. His style is easy, perspicuous and fluent. In short, he is a writer of whom any country might justly feel proud. Were I to attempt a parallel between the American Novelist and the "Northern Magician," I should say that Scott has more varied powers and a finer poetical mind, but in the management of their plots, intensity of interest, and the description of natural scenery, they are not very unequal. The Scotch romancer has greater acquirements and a more minute and intimate acquaintance with the history, manners and customs of past ages, but in all that appertains to sea life Cooper is superior, and does not fall short of his model in the ability with which he works up his incidents and developes his plots. This, you will think, is saying a great deal for a Scotchman, but such is my unbiassed opinion and the impression left upon my mind, after a careful perusal of the productions of both of these eminent writers of fictitious history.
