Take care to charge the proper method of violation of the statute!
For
example, if the letter is mailed to the district of indictment from another
district, be sure to charge a taking from the mails, or delivery according
to the
direction thereon, rather than a placing in the mail. Conversely, charge a
placing in the mail in the district of indictment of a letter addressed to
someone outside that district. SeeHagner v. United States,
285
U.S. 427 (1932) (indictment loosely and inartfully drawn).
