Between the drivers was the control panel. Ninety-nine percent automatic, those controls. They needed little human attention, and got little. There were never more than three men on duty here. This engine room almost operated itself.

It had ceased to operate itself, Jed Hargraves saw, as he forced open the last stubborn air-tight door separating the engine room from the rest of the ship. Ceased because—Involuntarily he cried out.

He could see the sky.

A great V-shaped notch straddled the back of the ship. Something, striking high on the curve of the hull, had driven through inches of magna steel, biting a gigantic chunk out of the ship. The beam from the sphere! That flashing streak of light that had driven through the defense screen. It had struck here.

"Jed! They're dead!"

That was Ron Val's voice, choking over the radio. One of the men in this engine room had been Hal Sarkoff, a black-browed giant from somewhere in Montana. Engines had behaved for Sarkoff. Intuitively he had seemed to know mechanics.

He and Ron Val had been particular friends.

"The air went," Hargraves said. "When that hole was knocked in the hull, the air went. The automatic doors blocked off the rest of the ship. The poor devils—"

The air had gone and the cold had come. He could see Sarkoff's body lying beside one of the drivers. The two other men were across the room. A door to the stern compartment was there. They were crumpled against it.

Hargraves winced with pain. He should have ordered everyone into space suits. The instant Nielson reported the approach of the sphere, Hargraves should have shouted, "Space suits" into the mike. He hadn't.
