why I want to come out here
after every dance. You know, I ..."

Her voice broke off suddenly, with a queer, rasping catch, as she seized
his arm in a frantic clutch and as quickly went limp. He stared at her
sharply, and understood instantly the message written in her eyes--eyes
now enlarged, staring hard, brilliant, and full of soul-searing terror
as she slumped down, helpless but for his support. In the act of
exhaling as he was, lungs almost entirely empty, yet he held his breath
until he had seized the microscope from his belt and had snapped the
lever to "emergency."

"Control room!" he gasped then, and every speaker throughout the great
cruiser of the void blared out the warning as he forced his already
evacuated lungs to absolute emptiness. "Vee-Two Gas! Get tight!"

Writhing and twisting in his fierce struggle to keep his lungs from
gulping in a draft of that noxious atmosphere, and with the unconscious
form of the girl draped limply over his left arm, Costigan leaped toward
the portal of the nearest lifeboat. Orchestra instruments crashed to the
floor and dancing couples fell and sprawled inertly while the tortured
First Officer swung the door of the lifeboat open and dashed across the

the space-suits always kept there, and opened its valves wide in order
to flush out of his uniform any lingering trace of the lethal gas.

He then leaped back to his companion. Shutting off the air, he released
a stream of pure oxygen, held her face in it, and made shift to force
some of it into her lungs by compressing and releasing her chest against
his own body. Soon she drew a spasmodic breath, choking and coughing,
and he again changed the gaseous stream to one of pure air, speaking
urgently as she showed signs of returning consciousness. Now, it was
Clio Marsden's life.

"Stand up!" he snapped. "Hang onto this brace and keep your face in this
air-stream until I get a suit around you! Got me?"

She nodded weakly, and, assured that she could now hold herself at the
valve, it was the work of only a minute to encase her in one of the
protective coverings. Then, as she sat upon a bench, recovering her
strength, he flipped on the lifeboat's
