Section 36, line 11, the word "common" should be inserted before the word "law." This section should be compared with section 2, and they should be consolidated, or preferably they should both be omitted as unnecessary and as being outside of the purview of this act. Section 38, line 23, there should be inserted after the word "musical" the word "-dramatic." Line 25, the word "make" should be canceled and there should be inserted the words "produce by." It is evident that the right to make belongs to the patentee of the device. Page 30, line 1, the words "ninety days" should be changed to "three months" as more convenient and as excluding any contention whether or not Sundays and holidays are included in the ninety days. The similar provision of the patent law reads "three months." Section 44 should be amended by inserting after "assignment", in line 12, the words: "and index the same under the name of the person by whom the original entry of copyright was made." Section 45 should be amended so that lines 21 to 23 shall read as follows: "signee shall in all cases give in the statutory notice of copyright prescribed by this act the name of the person by whom the original entry of the copyright was made." Without this provision the public will be put to great inconvenience in finding the original entry on which the copyright depends. The copyright notice should be of a clear and specific character so as to cause the public as little inconvenience and uncertainty as possible. Paragraph 52 should be amended by striking out "provided" and all thereafter to the end of the paragraph in lines 2 and 3 of page 33. This provision is altogether too broad and the courts should be left free to determine what are conditions precedent to a valid copyright and whether there has been any breach of them. Section 54 should be amended by striking out the words "the date of the" and inserting "that the affidavit states the dates of;" and in line 20 cancel the words "as stated in the said affidavit," and insert the words "which dates shall be given in the certificate." Section 55 provides for the destruction of card catalogues. The wisdom of this provision is very doubtful. A single card catalogue for each class of copyright work would save an immense amount of time and error to the public, and to the Librarian in making searches. Instead of periodically destroying card catalogues, they should be added to and preserved. As soon as they are destroyed, instead of being able to make one examination of one part of the card catalogue, the public will be compelled to examine a great number of periodically made printed indexes. I therefore suggest that the words "and thereupon", to and including the word "intervals," lines 9 to 12 of page 34, be canceled.
