and infinitely cleaner, the signal was hurled out on a tight beam from a gigantic parabolic reflector.Across sixty-seven million miles of space went the signal. Across the orbit of Venus it went in a vast chord. It arrived at the Venus Equilateral Station with less trouble than the original transmission through the Heaviside Layer. The signal was amplified and demodulated. It went into a decoupler machine where the messages were sorted mechanically and sent, each to the proper channel, into other coupler machines. Beams from Venus Equilateral were directed at Mars and at Terra. The Terra beam ended at Luna. Here it again was placed in the two-component beam and from Luna it punched down at Terra's Layer. It emerged into the atmosphere of Terra, as weak and as tired as it had been when it had come out of the Venusian Heaviside Layer. It entered a station in the Bahamas, was stripped of the interference, and put upon the land beams. It entered decoupling machines that sorted the messages as to destination. These various beams spread out across the face of Terra; the one carrying Korvus' message finally coming into a station at Ten Mile Road and Woodward. From this station at the outskirts of Detroit, it went upon land wires downtown to the International Hotel. The teletype machine in the office of the hotel began to click rapidly. The message to Wilneda was arriving.
And fifty-five minutes after the operator told Korvus that less than an hour would ensue, Wilneda was saying, humorously, "So, Korvus was drunk again last night--" 
Completion of Korvus' message to Wilneda completes also one phase of the tale at hand. It is not important. There were a hundred and fifty other messages that might have been accompanied in the same manner, each as interesting to the person who likes the explanation of the interplanetary communication service. But this is not a technical journal. A more complete explanation of the various phases that a message goes through in leaving a city on Venus to go to Terra may be found in the Communications Technical Review, Volume XXVII, number 8, pages 411 to 716. Readers more interested in the technical aspects are referred to the article.
But it so happens that Korvus' message was picked out of a hundred-odd messages because of one thing only. At the time that Korvus' message was in transit through the decoupler machines at The Venus Equilateral Relay Station, something of a material nature was entering the air lock of the station.
It was an unexpected visit.
Don Channing looked up at the indicator panel in his office and frowned in puzzlement. He punched a buzzer and spoke into the communicator on his desk.
"Find out who that is, will you, Arden?"
"He isn't expected," came back the voice of Arden Westland.
"I know that.
