Martin yelped the last words from the step at the back of the ambulance as it went bumping and rocking through the factory yard, through the bitter smoke, toward the shrinking crowd. He owned and commanded the city, he and the driver. They ignored traffic regulations, they disdained the people, returning from theaters and movies, who dotted the streets which unrolled before the flying gray hood. Let ’em get out of the way! The traffic officer at Chickasaw and Twentieth heard them coming, speeding like the Midnight Express—urrrrrr—blang-blang-blang-blang—and cleared the noisy corner. People were jammed against the curb, threatened by rearing horses and backing motors, and past them hurled the ambulance, blang-blang-blang-blang, with The Doctor holding a strap and swinging easily on his perilous seat.

At the hospital the hall-man cried, “Shooting case in the Arbor, Doc.”

“All right. Wait’ll I sneak in a drink,” said Martin placidly.

On the way to his room he passed the open door of the hospital laboratory, with its hacked bench, its lifeless rows of flasks and test-tubes.

“Huh! That stuff! Poking ’round labs! This is real sure-enough life,” he exulted, and he did not permit himself to see the vision of Max Gottlieb waiting there, so gaunt, so tired, so patient.

The six interns in Zenith General, including Martin and Angus Duer, lived in a long dark room with six camp beds, and six bureaus fantastic with photographs and ties and undarned socks. They spent hours sitting on their beds, arguing surgery versus internal medicine, planning the dinners which they hoped to enjoy on their nights off, and explaining to Martin, as the only married man, the virtues of the various nurses with whom, one by one, they fell in love.

Martin found the hospital routine slightly dull. Though he developed the Intern’s Walk, that quick corridor step with the stethoscope conspicuous in the pocket, he did not, he could not, develop the bedside manner. He was sorry for the bruised, yellowed, suffering patients, always changing as to individuals and never changing as a mass of drab pain, but when he had thrice dressed a wound, he had had enough; he wanted to go on to new experiences. Yet the ambulance work outside the hospital was endlessly stimulating to his pride.

The Doctor, and The Doctor alone, was safe by night in the slum called “the Arbor.” His black bag was a pass. Policemen saluted him, prostitutes bowed to him without mockery, saloon-keepers called out, “Evenin’, Doc,” and hold-up men stood back in doorways to let him pass. Martin had power, the first obvious power in his life. And he was led into incessant adventure.

He took a bank-president out of a dive; he helped the family conceal the disgrace; he irritably refused their bribe; and afterward, when he thought of how he might have dined with Leora, he was sorry he had refused it. He broke into hotel-rooms reeking with gas and revived would-be suicides. He drank Trinidad rum with a Congressman who advocated prohibition. He attended a policeman assaulted by strikers, and a striker assaulted by policemen. He assisted at an emergency abdominal operation at three o’clock in the morning. The operating-room—white tile walls and white tile floor and glittering frosted-glass skylight—seemed lined with fire-lit ice, and the large incandescents glared on the glass instrument cases, the cruel little knives. The surgeon, in long white gown, white turban, and pale orange rubber gloves, made his swift incision in the square of yellowish flesh exposed between towels, cutting deep into layers of fat, and Martin looked on unmoved as the first blood menacingly followed the cut. And a month after, during the Chaloosa River flood, he worked for seventy-six hours, with half-hours of sleep in the ambulance or on a police-station table.
