twinkling dimly as it swept up cosmic dust.[1]

The oncoming ship had been a dot in the sky. Now it was a round ball.

"Try them on the radio," Hargraves said. "They probably won't understand us but at least they will know we're trying to communicate with them."

There was a swirl of action at the radio panel.

"No answer," the radio operator said.

"Keep trying."

"Look!" Nielson shouted. "They've changed course. They're coming straight toward us."

The ball had bobbled in its smooth flight. As though caught in the attraction of a magnet it was coming straight toward them.

For an instant, Hargraves stared. Should he run or should he wait? He didn't want to run and he didn't want to fight. On the other hand, he did not want to take chances with the safety of the men under his command.

His mission was peaceful. Entirely so. But the ball was driving straight toward them. How big it was he could not estimate. It wasn't very big. Oddly, it presented a completely blank surface. No ports. And, so far as he could tell, there was no discharge from driving engines. The latter meant nothing. Their own ship showed no discharge from the Kruchek drivers. But no ports—

It came so fast he couldn't see it come. The flash of light! It came from the ball. For the fractional part of a second, the defense screen twinkled where the flash of light hit it. But—the defense screen was not designed to turn light or any other form of radiation. The light came through. It wasn't light. It carried a component of visible radiation but it wasn't light. The beam struck the earth ship.

Clang!

From the stern came a sudden scream of tortured metal. The ship rocked, careened, tried to spin on its axis. On the control panels, a dozen red lights flashed, winked off, winked on again. Heavy thuds echoed through the vessel. Emergency compartments closing.

Hargraves hesitated no longer.

"Full speed ahead!" he shouted at Red Nielson.
