Mr. SERVEN. That is what I say, that we sell almost no copies except for public performances. There are very few people who ever buy these for private inspection. Almost every single copy of this sort is sold for the purpose of public performance, and that is why this very thing has damaged us so much and estimated to have cut down our sales on those particular productions from 75 to 80 per cent. The CHAIRMAN. Who makes that estimate? Mr. SERVEN. Primarily I make that estimate from the best information I can get from gentlemen in the publishing business, and secondly, it is made from those who make the sales, whose sales are reduced. The CHAIRMAN. It ought to be very easy for the musical people to furnish their books and give us a verification of that statement. If before Mr. Tams and the gentlemen engaged in that business entered the field they were making, for instance, $10,000 a year, and that business has shrunk, according to your statement yesterday, 85 per cent, it ought to be very easy for them to give the committee that information. Mr. SERVEN. It so happens, Mr. Chairman, that our music publishers have other things to depend on. If they had only this I venture to say that the probability is that there would not be a single extended music work published in the United States to-day unless it was done solely through philanthropy. As to this question of notice, while I consider that aside from the point, because the law does not say that there shall be notice, but it says that we have complied with certain other things in the law, and we have to subscribe to that before we can get our copyright from the Librarian of Congress, yet this is a copy of the circular which last January, I understand, was sent to every musical society that the publishers knew of in the United States, specifically calling attention to the fact that there was such a law. So, in addition to whatever the law might have required in the question of notice, it would not be our fault that they did not have such notice, and in addition to that we have unanimously recommended that in case of every right of that sort where the right was reserved it should carry notice of it somewhere in a conspicuous place on the front of the work itself, so that there can not be in the future any question as to whether the fellow that uses it knows he is violating the law. But to come to what I think is the real meat of this question. This is purely a business question and nothing else, a question of contract---- The CHAIRMAN. I beg your pardon, you are not relying on your contract at all; you are relying on your statutory rights.
