He tried to sleep, but couldn't. The shuttle trip from the Port of Philadelphia to Hospital Seattle was
almost two hours long because of passenger stops at Hospital Cleveland, Eisenhower City, New
Chicago, and Hospital Billings. In spite of the help of the pneumatic seats and a sleep-cap, Dal could not
even doze. It was one of the perfect clear nights that often occurred in midsummer now that weather
control could modify Earth's air currents so well; the stars glittered against the black velvet backdrop
above, and the North American continent was free of clouds. Dal stared down at the patchwork of lights
that flickered up at him from the ground below.
Passing below him were some of the great cities, the hospitals, the research and training centers, the
residential zones and supply centers of Hospital Earth, medical center to the powerful Galactic
Confederation, physician in charge of the health of a thousand intelligent races on a thousand planets of a
thousand distant star systems. Here, he knew, was the ivory tower of galactic medicine, the hub from
which the medical care of the confederation arose. From the huge hospitals, research centers, and
medical schools here, the physicians of Hospital Earth went out to all corners of the galaxy. In the
permanent outpost clinics, in the gigantic hospital ships that served great sectors of the galaxy, and in the
General Practice Patrol ships that roved from star system to star system, they answered the calls for
medical assistance from a multitude of planets and races, wherever and whenever they were needed.
Dal Timgar had been on Hospital Earth for eight years, and still he was a stranger here. To him this was
an alien planet, different in a thousand ways from the world where he was born and grew to manhood.
For a moment now he thought of his native home, the second planet of a hot yellow star which Earthmen
called "Garv" because they couldn't pronounce its full name in the Garvian tongue. Unthinkably distant,
yet only days away with the power of the star-drive motors that its people had developed thousands of
years before, Garv II was a warm planet, teeming with activity, the trading center of the galaxy and the
governmental headquarters of the powerful Galactic Confederation of Worlds. Dal could remember the
days before he had come to Hospital Earth, and the many times he had longed desperately to be home
again.
He drew his fuzzy pink friend out of his pocket and rested him on his shoulder, felt the tiny silent creature
rub happily against his neck. It had been his own decision to come here, Dal knew; there was no one else
to blame. His people were not physicians. Their instincts and interests lay in trading and politics, not in the
life sciences, and plague after plague had swept across his home planet in the centuries before Hospital
Earth had been admitted as a probationary member of the Galactic Confederation.
But as long as Dal could remember, he had wanted to be a doctor. From the first time he had seen a
General Practice Patrol ship landing in his home city to fight the plague that was killing his people by the
thousands, he had known that this was what he wanted more than anything else: to be a physician of
Hospital Earth, to join the ranks of the doctors who were serving the galaxy.
Many on Earth had tried to stop him from the first. He was a Garvian, alien to Earth's climate and Earth's
people. The physical differences between Earthmen and Garvians were small, but just enough to set him
apart and make him easily identifiable as an alien. He had one too few digits on his hands; his body was
small and spindly, weighing a bare ninety pounds, and the coating of fine gray fur that covered all but his
face and palms annoyingly grew longer and thicker as soon as he came to the comparatively cold climate
