    (a) A subpena may be served by a United States marshal or his 
deputy, by Commission personnel, or by any person who is not a party to 
the proceeding and is not less than 18 years of age.
    (b) Service of a subpena upon the person named therein shall be made 
by exhibiting the original subpena to him, by reading the original 
subpena to him if he is unable to read, by delivering the duplicate
