Administrations which utilize air-mail communications for the transportation of their own ordinary mails shall so inform the other Administrations of the Union through the intermediary of the Inter- national Bureau, advising them at the same time of the effective date when use of such communications is inaugurated, the connections thus made available, as well as all changes made therein. 3409 Ante, p. 3407.
