"Because mind-talk more tiring to we," came the simple explanation. "It take much of we's forces. Us grow weak after much of them."

"That makes me hesitate to ask you to do any of it, then," the young SS man said. "I was hoping you could find out for me how many mines are operated on the planet, and if all of them are using you Guddus as slaves."

"Oh, yes, An-yon, me know that already," Geck's peculiar little face, which had become so friendly to Hanlon through long association, broke out into a smile that was quickly shadowed by sorrow at thought of the plight of his people. "There is nine mines. Human masters make Guddu work in all of they."

"Nine, eh?" Hanlon thought swiftly for a moment. "Do they all produce the same ores as this one?"

"Will have to find that for you, An-yon. You wait short space of time."

The Greenie grew silent and strained with concentration. Hanlon probed into the native's mind, wondering if he could follow it. And haltingly at first, but with growing ability as he learned the pattern, he found he could ride along on that telepathic beam.

The thoughts were far too swift for him to catch more than an occasional concept, but he was thrilled to realize he was actually telepathing, even though at second-hand.

One after another mind he could feel joining in that conference. There was much hostility and great fear when Geck first tried to explain about the human who was their friend, and had learned to talk with them. The Guddus on the other end of that "line" were tremendously skeptical, afraid, and very, very suspicious of the motives of any human being.

But Geck was eloquent and persuasive. Before long their fears began to lessen, and later they seemed to accept his assurance that "An-yon" was, indeed, both friendly and anxious to help them escape their slavery.

"The human An-yon is but one of the most of humans who are kind and just and ethical," he was surprised to hear Geck telepathing when he got so he could understand. "It is the few, such as those others who are here, who are not. These are bad men who come here just to get things for own selfish ends, and the good men, who are most, will stop them as soon as they can. An-yon come here just for that, to find out what those bad men do, and to stop them."
