It will occasionally happen that an author is produced in a country who is charged with a special message for another country. There will be something in the cast of his mind, or in the nature of his subject, which renders his writings more immediately or more generally suitable to the people of a land other than his own. We might cite as an example Washington Irving, who, though a sound American patriot, was essentially an English author, and whose earlier works are so English that many English people read them to this day, we are told, who do not suspect that the author was not their countryman. Washington Irving owed his literary career to this fact! His seventeen years' residence abroad enabled him to enjoy part of the advantage which all great authors would derive from an International Copyright, that is to say, he derived revenue from _both_ countries. During the first half of his literary career, he drew the chief part of his income from England; during the second half, when his Sketch-Book vein was exhausted, and he was again an American resident, he derived his main support from America. If he had never resided abroad, we never should have had a Washington Irving; if he had not returned home, he would have been sadly pinched in his old age. Alone among the American authors of his day or of any day, he had the market of the world for his works; and he only, of excellent American authors, has received anything like a compensation for his labor. The entire proceeds of his works during his lifetime were $205,383, of which about one third came to him from England. His average income, during the fifty years of his authorship, was about four thousand dollars a year. Less than any other of our famous authors he injured his powers by over-production, and it was only the unsteadiness of his income, the occasional failure of his resources, or the dread of a failure, that ever induced him to take up his pen when exhausted nature cried, Forbear! Cooper, on the contrary, who was read and robbed in every country, wrote himself all out, and still wrote on, until his powers were destroyed and his name was a by-word.
