Below him the bright lights of the landing fields and terminal buildings of the port of Philadelphia spread out in panorama, and he thought with a sudden pang of the great space-port in his native city, so very different from this one and so unthinkably far away. The field below was teeming with activity, alive with men and vehicles. Moments before, one of Earth's great hospital ships had landed, returning from a cruise deep into the heart of the galaxy, bringing in the gravely ill from a dozen star systems for care in one of Earth's hospitals. Dal watched as the long line of stretchers poured from the ship's hold with white-clad orderlies in nervous attendance. Some of the stretchers were encased in special atmosphere tanks; a siren wailed across the field as an emergency truck raced up with fresh gas bottles for a chlorine-breather from the Betelgeuse system, and a derrick crew spent fifteen minutes lifting down the special liquid ammonia tank housing a native of Aldebaran's massive sixteenth planet. All about the field were physicians supervising the process of disembarcation, resplendent in the colors that signified their medical specialties. At the foot of the landing crane a Three-star Internist in the green cape of the Medical Service--obviously the commander of the ship--was talking with the welcoming dignitaries of Hospital Earth. Half a dozen doctors in the Blue Service of Diagnosis were checking new lab supplies ready to be loaded aboard. Three young Star Surgeons swung by just below Dal with their bright scarlet capes fluttering in the breeze, headed for customs and their first Earthside liberty in months. Dal watched them go by, and felt the sick, bitter feeling in the pit of his stomach that he had felt so often in recent months. He had dreamed, once, of wearing the scarlet cape of the Red Service of Surgery too, with the silver star of the Star Surgeon on his collar. That had been a long time ago, over eight Earth years ago; the dream had faded slowly, but now the last vestige of hope was almost gone. He thought of the long years of intensive training he had just completed in the medical school of Hospital Philadelphia, the long nights of studying for exams, the long days spent in the laboratories and clinics in order to become a physician of Hospital Earth, and a wave of bitterness swept through his mind.
