 whenever within the period of such ad interim pro tection an authorized edition of such book shall be published within the United States, in accordance with the manufacturing provisions specified in section fifteen of this Act, and whenever the provisions of this Act as to deposit of copies, registration, filing of affidavit, and the printing of the copyright notice shall have been duly complied with, the copyright shall be extended to endure in such book for the full term elsewhere provided in this Act."

The ad interim provision requires the same formalities and fee as in the case of domestic works, except that only one copy of the foreign work in English need be deposited, and that this deposit copy need not contain the statutory notice of American copyright. The claimant is given thirty days after publication abroad in which to request reservation and a second thirty days after deposit of the foreign copy within which to publish or cause to be published an edition manufactured in America and thus to complete his copyright. This gives a period of ad interim protection, ranging from thirty days to sixty days, within which to obtain permanent copyright, the exact period depending upon the number of days elapsing after publication before deposit of the foreign copy in the Copyright Office. Thus a copy deposited on the day of publication will have thirty days in all within which to secure permanent copyright by the publication of the American-made edition, while a copy deposited on the thirtieth day after publication will have sixty days in alf ; but the failure to deposit the foreign copy within thirty days after publication, or the failure to publish an Americanmade edition within thirty days after such deposit, will forfeit the right to obtain copyright protection and throw the foreign work into the public domain,
