The magnetometer-needle flicked over. Its findings were recorded. As the plane went on it returned to a normal reading for fifty fathoms of seawater.
Half an hour later the seemingly private plane landed at the capital airport. Another half-hour, and its record and pictures were back at the air base, being examined and computed by hungry-eyed men.
Just as the pretty Morgan girl had said, there was a shack on the very tip of the cape. It was occupied by two men. They loafed. And only an electron camera could have used enough magnification to show one man laughing, as if at something the other had said. The camera proved—from five miles away—that there was no sadness afflicting them. One man laughed uproariously. But the rest of the planet was in no mood for laughter.
The magnetometer recording showed that a very large mass of magnetic material lay on the ocean bottom, fifty fathoms down. Minute modifications of the magnetic-intensity curve showed that there was electronic machinery in operation down below.
Bors made no report to the palace. King Humphrey was a conscientious and doggedly resolute monarch, but he was not an imaginative one. He would want to hold a cabinet meeting before he issued orders for the destruction of a space-ship that was only technically and not actually an enemy. Kandar had received an ultimatum from Mekin. An answer was required when a Mekinese fleet arrived off Kandar. Until that moment there was, in theory, no war. But, in fact, Kandar was already conquered in every respect except the landing of Mekinese on its surface. King Humphrey, however, would want to observe all the rules. And there might not be time.
The air force agreed with Bors. So squadron after squadron took off from the airfield, on courses which had certain things in common. None of them would pass over a fisherman's shack on Cape Farnell. None could pass over a spot five miles north-north-east magnetic from that cape's tip, where the bottom was fifty fathoms down and a suspicious magnetic condition obtained. One more thing unified the flying squadrons: At a given instant, all of them could turn and dive toward that fifty-fathom depth at sea, and they would arrive in swift and orderly succession. This last arrangement was a brilliant piece of staff-work. Men had worked with impassioned dedication to bring it about.
But only these men knew. There was no sign anywhere of anything more remarkable than winged squadrons sweeping in a seemingly routine exercise about the heavens. Even so they were not visible from the cape. The horizon hid them.
For a long time there was only blueness overhead, and the salt smell of the sea, and now and again flights of small birds which had no memory of the flight of their ancestors from ancient Earth. The planet Kandar rolled grandly in space, awaiting its destiny. The sun shone, the sun set; in another place it was midnight and at still another it was early dawn.
But from the high blue sky near the planet's capital, there came a stuttering as of a motor going bad. If anyone looked, a most minute angular dot could be seen to be fighting to get back over the land from where it had first appeared, far out at sea. There were moments when the stuttering ceased, and the engine ran with a smooth hum. Then another stutter.
The plane lost altitude. It was clear that its pilot fought to make solid ground before it crashed. Twice it seemed definitely lost. But each time, at the last instant, the motor purred—and popped—and the plane rose valiantly.
