"Sorry," grinned Arcot, "but most people know enough to stay out of the way of those things. Seriously, though, I didn't think the electrostatic curvature would be so slow to adjust. You see, when we build up our light-rate distortion field, other curvatures are affected. We get some gravity, some magnetic, and some electrostatic field distortion, too. You can see what happens when they don't leak their energy back into the coil.

"But we're busy with the instruments; leave the motorman alone!"

Morey was calling loudly for tests. Although the ship seemed to be behaving perfectly, he wanted check tests to make sure the relays were not being burned, which would keep them from responding properly. By rerouting the current around each relay, Arcot checked them one by one.

It was just as they had finished testing the last one that Fuller yelled.

"Hey! Look!" He pointed out the broad viewport in the side of the ship.

Far off to their left and far to their right, they saw two shining ships paralleling their course. They were shining, sleek ships, their long, longitudinal windows glowing with white light. They seemed to be moving at exactly the same speed, holding grimly to the course of the Ancient Mariner. They bracketed the ship like an official guard, despite the terrific velocity of the Earthmen's ship.

Arcot stared in amazement, his face suddenly clouded in wonder. Morey, who had come up from the power room, stared in equal wonder.

Quickly, Wade and Fuller slid into the ray control seats. Their long practice with the rays had made them dead shots, and they had been chosen long before as the ship's official ray operators.

"Lord," muttered Morey as he looked at the ships, "where can they have come from?"
