Chapter XLI: Section 15: contains a provision as to what shall happen if the

copyrighter does not deposit his copies in the office of the Librarian of Congress on time; and there is a proviso in lines 19, 20, and 21 which reads:

That in such case no action shall be brought for infringement of
the copyright until such requirements have been fully complied
with.

That ought to be amended by adding the words "or be based on any infringement begun before the time of that compliance," because otherwise the public would have no protection at all. A man could go on and innocently infringe during that year, and the only protection this section gives him is that he would not be sued until after the end of the year, but when sued the action would be retroactive; and that amendment ought to go in to perfect the section.
