What Mr. Jell would do, for example, would be to put a loaf of bread into the Box, and press a button, and presto, there would be _two_ loaves of bread, each perfectly alike, atom for atom. It would be absolutely impossible for anyone to tell them apart. This was the way Mr. Jell made most of his food, and all of his money. Once he had gotten one original dollar bill, the Box went on duplicating it--and bread, meat, potatoes, anything else Mr. Jell desired was instantly available at the touch of a button. * * * * * Once the Box duplicated a thing, anything, it was no longer necessary to have the original. The Box filed a record in its electronic memory, describing, say, bread, and Mr. Jell had only to dial a number any time he wanted bread. And the Box needed no fuel except dirt, leaves, old pieces of wood, just anything made out of atoms--most of which it would arrange into bread or meat or whatever Mr. Jell wanted, and the rest of which it would use as a source of power. So the Box made Mr. Jell entirely independent, but it did even more than that; it had one other remarkable feature. It could be used also as a transmitter and receiver. Of matter. It was, in effect, the Sears Roebuck catalogue of Mr. Jell's people, with its own built-in delivery service. If there was an item Mr. Jell needed, any item at all, and that item was available on any of the planets ruled by Mr. Jell's people, Mr. Jell could dial for it, and it would appear in the Box in a matter of seconds. The makers of the Box prided themselves on the speed of their delivery, the ease with which they could transmit matter instantaneously across light-years of space. Mr. Jell admired this property, too, but he could make no use of it. For once he had dialed, he would also be billed. And of course his Box would be traced to Earth. That Mr. Jell could not allow. No, he would make do with whatever was available on Earth. He had to get along without the catalogue. And he really never needed the catalogue, not at least for the first year, which was perhaps the finest year of his life. He lived in perfect freedom, ever-continuing joy, on the riverbank, and made some special friends: one Charlie, aged five, one Linda, aged four, one Sam, aged six. He spent a great deal of his time with these friends, and their parents approved of him happily as a free baby-sitter, and he was well into his second year on Earth when the first temptation arose. Bugs. Try as he might, Mr. Jell could not learn to get along with bugs. His air-conditioned, antiseptic, neat and odorless existence back home had been an irritation, yes, but he had never in his life learned to live with bugs of any kind, and he was too old to start now. But he had picked an unfortunate spot. The state of Florida was a heaven for Mr. Jell, but it was also a heaven for bugs.
