I am glad you have all had the opportunity to come here today for the opening of this modern medical center. This new hospital has been designed to provide for all the health needs of the local population in this area. Not only does it have a fully equipped emergency room, this new hospital also has a dental clinic, a maternity ward for newborn children, and an operating room that should be able to handle most of the anticipated medical cases in the region. The hospital will establish a transfer system to copy with the few difficult cases that might be encountered. Whenever special types of surgery are required and this hospital is not considered adequate to provide for the needs, specialty surgeons can easily be flown in from other hospitals. Any case that cannot be handled here at this hospital will be sent to the state hospital by helicopter.
    When the hospital is operating, it will have a full-time staff of three doctors as well as fourteen nurses and other employees. Since the hospital will be employing employees from many different skill levels, the local economy will also benefit from this hospital.
    In addition to the section of the medical center that we are opening today, there will be another section that will be completed by the beginning of summer. At the time that the entire project is completed, this medical center should serve the needs of this community well into the next century.
