Court attached significance to .the absence of special venue provisions. In United States v. Johnson, 323 U.S. 273, 65 S.Ct. 249, 89 L.Ed. 236 (1944), the Court held that the Federal Denture Act (which prohibited use of the mails for sending dentures made by unlicensed persons) did not create a continuing offense. The Court said : It is significant that when Congress desires to give a choice of trial, it does so by specific venue provisions giving jurisdiction to prosecute in any criminal court of the United States through which a process of wrongdoing moves. . . . The absence of such a provision would in itself be significant. Id. at 276, 65 S.Ct. at 251. 7 . Supra, note 4. See Mahaffey v.
