Within the last year, the number of books written by American authors, which have been successful in Britain, is greater than that of foreign works which have been successful in this country. Robertson’s work on Palestine, Stephens’s Travels in Central America, Catlin’s book on North American Indians, Cooper’s Deerslayer, the last volume of Bancroft’s American history, several works prepared by Anthon for the schools--here is a list of American works republished in England within the year for which we should be puzzled to find an equivalent in works written in England within the same time, and republished here. Our eminent authors are still engaged in their literary labors. Cooper within a fortnight past has published a work stamped with all the vigor of his faculties, Prescott is occupied in writing the History of Peru, Bancroft is engaged in continuing the annals of his native country, Sparks is still employed in his valuable historical labors, and Stephens is pushing his researches in Central America, with a view of giving their results to the world. We were told, the other day, of a work prepared for the press by Washington Irving, which would have appeared ere this but for the difficulties in the way of securing a copyright for it in England, as well as here. He drew an inspiring picture of the effect of the success of these authors in raising up aspirants for literary fame. Irving had just told him, he wrote, “that if American literature continued to make the same progress as it had done for twenty years past, the day was not very far distant when the greater number of books designed for readers of the English language would be produced in America.”
