Almost to a man, our publishers are in favor of an International Copyright. We have been able to hear of but one exception, and this is the publisher of but one book,--Webster's Dictionary,--the work of all others now in existence that would profit most from just protection in foreign countries. There is an impression in many circles that the Harpers are opposed to it. We are enabled to state, upon the authority of a member of that great house, that this is not now, and never has been, the case. Messrs. Harper comprehend, as well as we do, that they would gain more from the measure than any other house in the world; because it is the natural effect of law, while it protects the weak, to legitimate and establish the dominion of the strong. International Copyright would benefit every creature connected with publishing, but it would benefit most of all the great and wealthy houses. The Harpers have spent tens of thousands in enforcing the observance of the courtesy of the trade, but they cannot enforce it. It is a work never done and always beginning. It cost them four hundred of our ridiculous dollars for the advance sheets of each number of Mr. Dickens's last novel; and within forty-eight hours of the publication of the Magazine containing it, two other editions were for sale under their noses. The matter for "Harper's Magazine" often costs three or four thousand dollars a number; can any one suppose that the proprietors _like_ to see Blackwood and half a dozen other British magazines sold all over the country at a little more than the cost of paper and printing? They like it as little as the proprietors of Blackwood like it. This is a wrong which injures two nations and benefits one printer; and that printer would himself do better if he could obtain exclusive rights by fair purchase. No; Messrs. Harper, we are happy to state, are decidedly in favor of an International Copyright, and so is every other general publishing house in the country of which we have any knowledge.
