purposes. The Obligation, which is not an oath but a solemn expression of intention, is subscribed to at the ceremony. The Obligation essentially states the duties and responsibilities of the engineer. Following the Obligation, the Iron Ring is placed on the little finger of the working hand, and is worn by the engineer as a symbol and a reminder. As originally conceived, the engineer's iron ring rubs against the drawings and paper upon which the Engineer writes and even in modern times, serves as a reminder when working on a computer. Previously, a biblical passage was quoted: 2 Esdras, Chapter 4, Verses 5-10. More generally today Kipling's poem, the Hymn of Breaking Strain is recited. The Obligation is private, though not necessarily secret. However, it is customary for those who have gone through it to not discuss the details of the Calling with others, even engineers from other countries. The ceremony is open only to candidates, those who have already undergone the ritual and at some sites, guests invited by candidates. As part of the preparation for the ritual, candidates are instructed not to discuss the details of the ritual with the media. A reminder of this is provided at the end of the ceremony in the form of a written instruction that states: "The Rule of Governance provides that there shall be no publicity in connection with the Ritual." Commemorating the 75th anniversary, the Ritual of the Calling of an Engineer domestic-rate stamp was issued on 25 April 2000. Designer Darrell Freeman's "head-to-foot" layout incorporates the symbolic iron ring that is presented as part of the ceremony. The ring also visually links the four engineering achievements featured on this stamp. The Ritual of the Calling of an Engineer has a very simple purpose: To direct the newly qualified engineer toward a consciousness of the profession and its social significance and indicating to the more experienced engineer their responsibilities in welcoming and supporting the newer engineers when they are ready to enter the profession. The ring symbolizes the pride which engineers have in their profession, while simultaneously reminding them of their humility. The ring serves as a reminder to the engineer and others of the engineer's obligation to live by a high standard of professional conduct.
