The Scientist spoke into an intercom microphone, and within a few minutes, a large lump of iron--a broken casting--was brought in. Arcot suspended it on the molecular beam while Wade melted it with the heat beam. It melted and collapsed into a ball that glowed brilliantly and flamed as its surface burned in the oxygen of the air. Wade cut off his heat ray, and the ball quickly cooled under the influence of the molecular beam until Arcot lowered it to the floor, a perfect sphere crusted with ice and frost. Arcot continued for the better part of an hour to explain to the Council exactly what he had, how they could be used, and what materials and processes were needed to make them. When he was finished, the Supreme Three conferred for several minutes. Then the Scientist asked, through Torlos: "How can we repay you for these things you have given us?" "First, we need lead to fuel our ship." Arcot gave them the exact specifications for the lead wire they needed. He received his answer from the man of Business and Manufacturing. "We can give you that easily, for lead is cheap. Indeed, it seems hardly enough to repay you." "The second thing we need," Arcot continued, "is information. We became lost in space and are unable to find our way home. I would like to explain the case to the Astronomer." The Astronomer proved to be a man of powerful intelligence as well as powerful physique, and was a better transmitter than receiver. It took every bit of Arcot's powerful mind to project his thoughts to the man. He explained the dilemma that he and his friends were in, and told him how he could recognize the Galaxy on his plates. The Astronomer said he thought he knew of such a nebula, but he would like to compare his own photographs with Arcot's to make sure. "In return," Arcot told him, "we will give you another weapon--a weapon, this time, to defeat the astronomer's greatest enemy, distance. It is an electrical telescope which will permit you to see life on every planet of this system. With it, you can see a man at a distance ten times as great as the distance from Nansal to your sun!" Eagerly, the Astronomer questioned Arcot concerning the telectroscope, but others were clamoring for Arcot's attention. The Biologist was foremost among the contenders; he seemed worried about the possibility of the alien Earthmen carrying pathogenic bacteria. "Torlos has told us that you have an entirely different internal organization. What is it that is different? I can't believe that he has correctly understood you." Arcot explained the differences as carefully as possible. By the time he was finished, the Biologist felt sure that any such creature was sufficiently far removed from them to be harmless biologically, but he wanted to study the Man of Earth further.
