The next publications of Mr. Cooper were his _Gleanings in Europe_. _Sketches in Switzerland_, first and second series, each in two volumes, appeared in 1836, and none of his works contain more striking and vivid descriptions of nature, or more agreeable views of character and manners. It was followed by similar works on France, Italy, and England. All of these were well received, notwithstanding an independence of tone which is rarely popular, and some absurdities, as, for example, the imputations upon the American Federalists, in the Sketches of Switzerland. The book on England excited most attention, and was reviewed in that country with as much asperity as if its own travellers were not proverbially the most shameless libellers that ever abused the hospitality of nations. Altogether the ten volumes which compose this series may be set down as the most intelligent and philosophical books of travels which have been written by our countrymen. _The American Democrat, or Hints on the Social and Civil Relations of the United States of America_, was published in 1835. The design is stated to be, "to make a commencement toward a more just discrimination between truth and prejudice." It is essentially a good book on the virtues and vices of American character. For a considerable time Mr. Cooper had entertained an intention of writing _The History of the Navy of the United Stated_, and his early experience, his studies, his associations, and above all the peculiar felicity of his style when treating of nautical affairs, warranted the expectation that his work would be a solid and brilliant contribution to our historical literature. It appeared in two octavo volumes in 1839, and reached a second edition in 1840, and a third in 1846.[A] The public had no reason to be disappointed; great diligence had been used in the collection of materials; every subject connected with the origin and growth of our national marine had been carefully investigated, and the result was presented in the most authentic and attractive form. Yet a warm controversy soon arose respecting Mr. Cooper's account of the battle of Lake Erie, and in pamphlets, reviews, and newspapers, attempts were made to show that he had done injustice to the American commander in that action. The multitude rarely undertake particular investigations; and the attacks upon Mr. Cooper, conducted with a virulence for which it would be difficult to find any cause in the History, assuming the form of vindications of a brave and popular deceased officer, produced an impression so deep and so general that he was compelled to defend the obnoxious passages, which he did triumphantly in a small volume entitled _The Battle of Lake Erie, or Answers to Messrs. Burgess, Duer, and Mackenzie_, published in 1843, and in the notes to the last edition of his Naval History. Those who read the whole controversy will perceive that Mr. Cooper was guided by the
