What the general knowledge of the French language has done for French literature, all of that, and more than that, an International Copyright law would do for the literature of Great Britain and the United States. Here are four great and growing empires, Great Britain, the United States, the Dominion of Canada, and the states of Australia, in which the same language is spoken and similar tastes prevail. In all these nations there is a spirit abroad which will never rest content until the whole population are readers, and those readers will be counted by hundreds of millions. Already they are so numerous, that one first-rate literary success, one book excellent enough to be of universal interest, would give the author leisure for life, if his rights were completely protected by international law. What a field for honorable exertion is this! And how can these empires fail to grow into unity when the cultivated intelligence of them all shall be nourished from the same sources, and bow in homage to the same commanding minds? Wanting this protection, the literature of both countries languishes. The blight of over-production falls upon immature genius, masterpieces are followed by labored and spiritless repetitions, and men that have it in them to inform and move mankind grind out task-work for daily bread. One man, one masterpiece, that is the general law. Not one eminent literary artist of either country can be named who has not injured his powers and jeoparded his fame by over-production. We do not address a polite note to Elias Howe, and ask him how much he would charge for a "series" of inventions equal in importance to the sewing-machine. We merely enable him to demand a dollar every time that _one_ conception is used. Imagine Job applied to for a "series" of Books of Job. Not less absurd is it to compel an author to try and write two Sketch-Books, two David Copperfields, two Uncle Toms, two Jane Eyres, or two books like "The Newcomes." When once a great writer has given such complete expression of his experience as was given in each of those works, a long time must elapse before his mind fills again to a natural overflow. But, alas! only a very short time elapses before his purse empties.
