thick. In time, there stretches behind you more of this space-time event, reaching to, perhaps, 1905, of which we see a cross section here at right angles to the time axis, and as thick as the present. At the far end is a baby, smelling of sour milk and drooling its breakfast on its bib. At the other end lies, perhaps, an old man some place in the 1980s. Imagine this space-time event, which we call Rogers, as a long pink worm, continuous through the years. It stretches past us here in 1939, and the cross section we see appears as a single, discrete body. But that is illusion. There is physical continuity to this pink worm, enduring through the years. As a matter of fact, there is physical continuity in this concept to the entire race, for these pink worms branch off from other pink worms. In this fashion the race is like a vine whose branches intertwine and send out shoots. Only by taking a cross section of the vine would we fall into the error of believing that the shootlets were discrete individuals."
    He paused and looked around at their faces. One of them, a dour, hard-bitten chap, put in a word.
    "That's all very pretty, Pinero, if true, but where does that get you?"
    Pinero favored him with an unresentful smile. "Patience, my friend. I asked you to think of life as electrical. Now think of our long, pink worm as a conductor of electricity. You have heard, perhaps, of the fact that electrical engineers can, by certain measurements, predict the exact location of a break in a transatlantic cable without ever leaving the shore. I do the same with our pink worms. By applying my instruments to the cross section here in this room I can tell where the break occurs; that is to say, where death takes place. Or, if you like, I can reverse the connections and tell you the date of your birth. But that is uninteresting; you already know it."
    The dour individual sneered. "I've caught you, doc. If what you say about the race being like a vine of pink worms is true, you can't tell birthdays, because the connection with the race is continuous at birth. Your electrical conductor reaches on back through the mother into a man's remotest ancestors."
    Pinero beamed. "True, and clever, my friend. But you have pushed the analogy too far. It is not done in the precise manner in which one measures the length of an electrical conductor. In some ways it is more like measuring the length of a long corridor by bouncing an echo off the far end. At birth there is a sort of twist in the corridor, and, by proper calibration, I can detect the echo from that twist."
    "Let's see you prove it!"
    "Certainly, my dear friend. Will you be a subject?"
    One of the others spoke up. "He's called your bluff, Luke. Put up or shut up."
    "I'm game. What do I do?"
    "First write the date of your birth on a sheet of paper, and hand it to one of your colleagues."
    Luke complied. "Now what?"
    "Remove your outer clothing and step upon these scales. Now tell me, were you ever very much thinner, or very much fatter, than you are now? No? What did you weigh at birth? Ten pounds? A fine bouncing baby boy. They don't come so big anymore."
    "What is all this flubdubbery?"
    "I am trying to approximate the average cross section of our long pink conductor, my dear Luke. Now will you seat yourself here? Then place this electrode in your mouth. No, it will not hurt you; the voltage is quite low, less than one microvolt, but I must have a good connection." The doctor left him and went behind his apparatus, where he lowered a hood over his head before touching his controls. Some of the exposed dials came to life and a low humming came from the machine. It stopped and the doctor popped out of his little hideaway.
    "I get sometime in February, 1902. Who has the piece of paper with the date?"
    It was produced and unfolded. The custodian read, "February 22, 1902."
    The stillness that followed was broken by a voice from the edge of the little group. "Doc, can I have another drink?"
    The
