enticing you." "That's not very complimentary to either of us," said Ackerman. Joan smiled honestly. "No, it isn't. But it is true, Lester. You see, I'm a gatherer of facts; I know how people have been trying to use you. I promise—we will not." Tod smiled at her and then asked: "Why the general call, Barry?" Barry grinned. He gave them a brief resume of the talk and discussion, and Ackerman's questions of why it couldn't be done by copying the models used to bring them through. Then, with a flourish and a beautifully executed counterfeit of Lester Ackerman's voice, tone, and diction, said: "Why didn't anybody think to ship through a physicist?" Laughter rang through the ship. Barry himself broke down and leaned weakly against the desk. Tod Laplane fell inert into a chair and shook with gales of silent laughter. Louis Ford merely gulped inanely, and Joan added her mirth in a gurgling contralto. "Okay," snapped Ackerman, "so soon as I find the face I dropped here somewhere, I'll leave." That stopped the laughter. "Look, Ackerman, you're the great physicist; why should we have another?" Ackerman snorted. "The next character who calls me a 'great physicist' either with or without capital letters is going to get a mouthful of fist," he snarled; "I'm tired of being the main point in a joke." Barry sobered quickly. "It is not used in a sense of ridicule or insult." "I don't give a damn how it is used. I don't like a lot of people calling me a veritable messiah. I'd not like it even if their tongues weren't shoved eight miles out in their cheeks. So stop it, unless you'd like to go a few swift ones with me." Barry nodded. "Sorry, Ackerman. But—you understand—we know you brought us here. Within your own mind and your own ability, you have the secret to the big question." "About all I know about the physics of this business is that it started with a few grams of temperon." "We'll get you some temperon," said Barry. "And a cyclotron. And most anything else you're likely to need." "Good," snorted Ackerman. "Get me a lie detector; eight gallons of scopolamine and a psychiatrist—and have 'em comb my
