It has never been intended by the copyright law to use the word "performance," excepting of such works as are only useful when represented or "performed" in a dramatic sense. The word "dramatic" has not always seemed sufficiently broad, and the words "musical composition" have often been added to include operas, oratorios, and musical works that are not purely dramatic, and yet are partially so. It is submitted that it has never been the intention of the law to make the mere singing of a song from copyrighted notes that have been paid for, or the playing of music, infringements of copyright, and it is believed that this section will carry out the full intent of the law if the word "dramatic" be coupled with the word "musical," as above indicated. In view of the use of the word "performance" in other parts of this bill for the purpose of including the use of automatic mechanical devices, it should be made clear that the word "performance," in line 5, has nothing beyond its ordinary significance. I suggest that this can best be attained by striking out the word "performance," in line 5, and inserting the word "representation." Section 15 should be amended by striking out the words "if, by reason" and the rest of line 11 and lines 12 and 13. It is plain that these words in the bill leave an open door for free publication which brings a work within the public domain, and subsequent monopoly of the work upon a mere allegation of error. The Librarian has not the facilities or legal machinery to try such question of error, and it should be left to the courts to determine whether there has been an error or omission, and whether by reason thereof any condition precedent for a valid copyright has been left unperformed. Page 12, line 13, the words "bulk of the" should be stricken out. These words are uncertain and would allow the proprietor to omit the notice from 49 per cent of the edition. This would clearly amount to insufficient notice to the public and could be made the instrument of fraud. Line 14 and the remainder of the section are entirely sufficient for the purpose without the words "bulk of the." Section 17, line 22, the words "be extended to" should be canceled, and at the end of line 24 the words "such term beginning with the date of filing the request for the reservation of the copyright," should be inserted. There appears to be no reason for granting more than the specific term, which the law will provide, in the case which section 17 is intended to cover. Section 18 relates to the term of copyright.
