"Take over, Mr. Marsden," he said. "Lay a course for Parth."

"Aye, sir," I replied, slipping into the chair and fastening the web. I slipped the helmet on my head and instantly I was a part of the ship. It's a strange feeling, this synthesis of man and metal that makes a fighting ship the metallic extension of the Commander's will. I was conscious of every man on duty. What they saw I saw, what they heard I heard, through the magic of modern electronics. The only thing missing was that I couldn't feel what they felt, which perhaps was a mercy considering the condition of the crew. Using the sensor circuits in the command helmet, I let my perception roam through the ship, checking the engines, the gun crews, the navigation board, the galley—all the manifold stations of a fighting ship. Everything was secure, the ship was clean and trimmed, the generators were producing their megawatts of power without a hitch, and the converters were humming contentedly, keeping us in the blue as our speed built to fantastic levels.

I checked the course, noted it was true, set the controls on standby and relaxed, half dozing in the chair as Lume after Lume dropped astern with monotonous regularity.

An hour passed and Halloran came up to relieve me. With a sigh of relief I surrendered the chair and headset. The unconscious strain of being in rapport with ship and crew didn't hit me until I was out of the chair. But when it did, I felt like something was crushing me flat. Not that I didn't expect it, but the "Lachesis" was worse than the "Clotho" had ever been.

I had barely hit my couch when General Quarters sounded. I smothered a curse as I pounded up the companionway to my station at the bridge. Chase was there, stopwatch in hand, counting the seconds.

"Set!" Halloran barked.

"Fourteen seconds," Chase said. "Not bad. Tell the crew well done." He put the watch in his pocket and walked away.

I picked up the annunciator mike and pushed the button. "Skipper says well done," I said.

"He got ten seconds out of us once last trip," Halloran said. "And he's been trying to repeat that fluke ever since. Bet you a munit to an 'F' ration that he'll be down with the section chief trying to shave off another second or two. Hey!—what's that—oh ..." He looked at me. "Disturbance in Cth yellow, straight down—shall we go?"

"Stop ship," I ordered. "Sound general quarters." There was no deceleration. We merely swapped ends as the alarm sounded, applied full power and stopped. That was the advantage of Cth—no inertia. We backtracked for three seconds and held in middle blue.
