Historical and Revision Notes

Based on title 18, U.S.C., 1940 ed., § 279 (Mar. 4, 1909, ch. 321, § 165, 35 Stat. 1119). Mandatory punishment provision was rephrased in the alternative. Reference to persons causing or procuring was omitted as unnecessary in view of definition of “principal” in section 2 of this title. Changes were also made in phraseology.
