29 U.S. Code § 9a. Credit of receipts
This section and sections 9 and 9b of this title comprised sections 1 to 3 of act Apr. 13, 1934, which were to terminate one year after Apr. 13, 1934, pursuant to section 4 of act Apr. 13, 1934, set out as a Codification note under section 9 of this title. Such sections were temporarily extended by acts Apr. 11, 1935, and June 15, 1937, and were made permanent by act Apr. 15, 1939.
 So in original. Probably should be “hereafter”.
