Morgan grabbed for his guns and the cabin of the small craft was filled with the _crack-crack_ of swift gun fire. Morgan fired once; Jeffries twice. Black Morgan missed, but Jeffries' first shot shattered the pirate's right wrist. The other gun dropped out of his hand from shock, and Jeffries strode up and covered the beaten pirate. Jeffries did not return to his ship, but he took over the pirate's small craft and drove it to Terra. He handed the pirate over to Captain Edwards with a smile. "This is he," he grunted. "And now what?" "You've won," smiled Edwards. His pleasure was honest. "If he's Black Morgan, you've won, and we can easily hush up any trouble. But can you prove it?" "Sure," grinned Jeffries. "Cell him, and then come up to training school on the roof. This takes demonstration." "O.K.," smiled Edwards. "It's your show." * * * * * Jeffries faced the group of experts, scientists, and police officials. At one side of him was the mock-up of the celestial globe used in training rookie spacemen. On the table beside him was a pile of equipment. "This," he said, holding up the equipment, "is familiar. It is a small detector-pulse receiver. It is coupled with an attenuator and a variable delay line, and a minute re-transmitter. The celestial globe will show a target approaching the ship at a velocity exceeding the speed of light, and will match the ship's acceleration, velocity, and course in microseconds." He started his equipment, and across the celestial globe in three distant flashes came a flitting target, to stop short of the ship's spotter in the center of the globe. From the other detecting equipment came indications and presentations as to type of drive, size of ship, and wave bands of the other ship's radiation. Jeffries laughed, turning off his equipment. "When equipment is very sensitive, in order to collect information from great distances, a rather minute transmitter can produce a heavy target," he said. "Now, above the dome of the building--watch!" He turned a square box at the sky and set it going. Black Morgan's ship came swooping down, to stand above the observation dome of the building, its rifles trained on the men inside. Jeffries turned dials and the turret turned slowly. He manipulated another dial and the big ship turned to face away. Then it receded and was gone in a twinkling of an eye. "Three-dimensional projector," he growled. "Just what they were using for moving pictures for a hundred years. And there's your answer!" Captain Edwards stood up and nodded. "But look," he said. "How did the contact come?"
