of time, twice, to realize that I was about to be sent or led between the disrupting plates of your atomic duplicator." "The man with the brass buttons," Burgess said slowly. "Do you think it's Mawson?" "Either him or a robot he's made to keep his machine fed." When Burgess scowled, Jerry shrugged and appended, "It is his machine, for all practical purposes. He's the boss of that hungry electronic monster, Doctor, however the hospital feels about it." "This Carol. Is she a real woman, or a figment of your imagination, wishful thinking?" "She's real enough," Jerry sighed. "She's the personal secretary of the entire Space zoology program. I take her out sometimes. There's nothing special between us."

We'll try someone else, if your outfit will send someone, and see what happens. If he fails, or if they won't supply us with any
