The new British measure as prepared in 1910 included as incident to copyright the sole right "in the case of a literary, dramatic or musical work, to make any record, perforated roll, cinematograph film, or other contrivance by means of which the work may be mechanically performed or delivered," thus in the simplest fashion completely covering the control of mechanical reproduction in conformity with the convention of Berlin. But in the Parliament of 1911 the bill emerged from committee stage with an elaborate proviso, based on the American precedent, excepting from the definition of infringement contrivances for the mechanical reproduction of sounds on (1) proof that the copyright owner has previously acquiesced in mechanical reproduction, (2) prescribed notice of intention, and (3) payment of royalty of 2-1/2 or 5 per cent with a minimum of a halfpenny for each record, or in the case of different works on the same record, to each copyright proprietor. {Sidenote: The Berne situation, 1886} When the international representatives met at Berne in 1886, the mechanical reproduction of music was confined chiefly if not wholly to Swiss music-boxes and orchestrions and to hand-organs, of comparatively little commercial importance; and, possibly with some thought of the recognition of the hospitality of Switzerland, little emphasis was placed on the protection of musical composers against mechanical reproduction of their works. In fact, the final protocol of the Berne Convention of 1886 contained, as clause 3, the following paragraph: "It is understood that the manufacture and sale of instruments for the mechanical reproduction of musical airs which are copyright, shall not be considered as constituting an infringement of musical copyright." {Sidenote: Lack of action at Paris, 1896} Despite strong representations at the congresses of the International Association for the protection of literary property, held at London in 1890, Neufchatel in 1891, and Milan in 1892, and a vigorous endeavor in connection with the Paris convention of 1896 to replace this clause, it was not modified until the convention of Berlin in 1908, in preparation for which a strong resolution was passed at the congress of the International Association at Vevey in 1901. {Sidenote: The Berlin provision, 1908} With the increasing development of the phonograph and of the mechanical player, mechanical reproductions became so important a matter to musical composers and publishers, that much of the discussion in respect to the amendatory convention of Berlin of 1908 was upon this subject. In the amended convention, the subject was fully covered by article 13: "Authors of musical works have the exclusive right to authorize: (1) the adaptation of these works to instruments serving to reproduce them mechanically; (2) the public performance of the same works by means of these instruments.
