"It's weak," observed Burleigh. "We'll try answering it."
Moran stirred, and he knew that every one of the others was conscious of the movement. But they didn't watch him suspiciously. They were alert by long habit. Burleigh said they'd been Underground people, fighting the government of their native world, and they'd gotten away to make it seem the revolt had collapsed. They'd go back later when they weren't expected, and start it up again. Moran considered the story probable. Only people accustomed to desperate actions would have remained so calm when Moran had used desperate measures against them.
Burleigh picked up the transmitter-microphone.
"Calling ground," he said briskly. "Calling ground! We pick up your signal. Please reply."
He repeated the call, over and over and over. There was no answer. Cracklings and hissings came out of the speaker as before, and the thin and reedy wabbling whine continued. The Nadine went on toward the enlarging cloudy mass ahead.
Burleigh said;
"Well?"
"I think," said Carol, "that we should land. People have been here. If they left a beacon, they may have left an identification of the planet. Then we'd know where we are and how to get to Loris."
Burleigh nodded. The Nadine had cleared for Loris. That was where it should make its next landing. The little yacht went on. All five of its proper company watched as the planet's surface enlarged. The ice-cap went out of sight around the bulge of the globe, but no markings appeared. There were cloud-banks everywhere, probably low down in the atmosphere. The darker vague areas previously seen might have been highlands.
"I think," said Carol, to Moran, "that if it's too tropical where this signal's coming from, we'll take you somewhere near enough to the ice-cap to have an endurable climate. I've been figuring on food, too. That will depend on where we are from Loris because we have to keep enough for ourselves. But we can spare some. We'll give you the emergency-kit, anyhow."
