Joseph McKenna, United States v. Gay — Opinion of the Court
“ On January 11, 1916, he was notified by letter from the Navy Department that he had been selected for duty in connection with the Naval Intelligence Office in time of war and requested, in case of return to the United States and to Washington, to call at that office, but 'should you remain abroad indefinitely, and opportunity offer, it is requested that you confer with the naval attache at Paris.' The letter was transmitted to him through the naval attache at Paris, with request to acknowledge receipt, which he did on January 28, 1916. ”
