Our genetic debt to him is both indirect and direct. The indirect debt lies in the fact that migration is a sorting device, a forced Darwinian selection, under which superior stock goes to the stars while culls stay home and die. This is true even for those forcibly transported (as in the twenty-fourth and twenty-fifth centuries), save that the sorting then takes place on the new planet. In a raw frontier weaklings and misfits die; strong stock survives. Even those who migrate voluntarily still go through this second drastic special selection. The Howard Families have been culled in this fashion at least three times.

Our genetic "debt" to the Senior is even easier to prove. Part of it needs only simple arithmetic. If you live anywhere but on Old Home Terra-and you almost certainly do if you read this, in view of the present miserable state of "The Fair Green Hills of Earth"-and can claim even one member of the Howard Families among your ancestors-and most of you can-then you are most probably descended from the Senior.

By the official Families' genealogies this probability is 87.3 percent. You are descended from many other twentieth century members of the Howard Families, too, if you are descended from any of them, but I speak here only of Woodrow Wilson Smith, the Senior. By the Crisis Year 2136 nearly one-tenth of the youngest generation of the Howard Families were descended from the Senior "legitimately"-by which I mean that each linking birth was so recorded in the Families' records and ancestry confirmed by such tests as were available at the time. (Even blood typing was not known when the breeding experiment started, but the culling process made it strongly to a female's advantage not to stray, at least not outside the Families.)

By now the cumulative probability is, as I have said, 87.3 percent if you have any Howard ancestor-but if you have a Howard ancestor from a recent generation, your probability climbs toward an effective 100 percent.

But, as a statistician, I have reason to believe (backed by computer analyses of blood types, hair types, eye color, tooth count, enzyme types, and other characteristics responsive to genetic analysis)-strong reason to believe that the Senior has many descendants not recorded in genealogies, both inside and outside the Howard Families.

To put it mildly, he is a shameless old goat whose seed is scattered all through this part of our Galaxy.

Take the years of the Exodus, after he stole the New Frontiers. He was not married even once during those years, and ship's records and legends based on memoirs of that time suggest that he was, in an early idiom, a "woman hater," a misogynist.

Perhaps. Biostatistical records (rather than genealogies), when analyzed, suggest that he was not that unapproachable. The computer that analyzed it offered to bet me even money on more than one hundred offspring fathered by him during those years. (I refused the bet; that computer beats me at chess even though I insist on a one-rook advantage.)

I do not find this surprising, in view of the almost pathological emphasis placed on longevity among the Families at that time. The oldest male, if still virile-and he certainty was-would have been subjected to endless temptation, endless opportunity, by females anxious to have offspring of his demonstrated superiority-"superiority" by the only criterion the Howard Families respected. We can assume that marital status would not matter much; all Howard Families marriages were marriages of convenience-Ira Howard's will insured that-and they were rarely for life. The only surprising aspect is that so few fertile females managed to trip him when unquestionably so many thousands were willing. But he was always fast on his feet.

As may be-If today I see a man with sandy red hair, a big nose, an easy disarming grin, and a slightly feral look in his gray-green eyes, I always wonder how recently the Senior has passed through that part of the Galaxy. If such a stranger comes close to me, I put my hand on my purse: If he speaks to me, I resolve not to make wagers or promises.

But how did the Senior, himself only a third-generation member of Ira Howard's breeding experiment, manage to live and stay young his first three hundred years without artificial rejuvenation?

A mutation, of course-which simply says that we don't know. But in the course of his several rejuvenations we have learned a little about his physical makeup. He has an unusually large heart that beats very slowly. He has only twenty-eight teeth, no caries, and seems to be immune to infection. He has never had surgery other than for wounds or for rejuvenation procedures. His reflexes are extremely fast-but appear always to be reasoned, so one may question the correctness of the term "reflex." His eyes have never needed correction either for distance or close work; his hearing range is abnormally high, abnormally low, and is unusually acute throughout his range. His color vision includes indigo. He was born without prepuce, without vermiform appendix-and apparently without a conscience.

I am pleased that he is my ancestor.

PREFACE TO REVISED EDITION

In this abridged popular edition the technical appendix has been published separately in order to make room for an account of the Senior's actions after he left Secundus until his disappearance. An apocryphal and obviously impossible tale of the last events in his life has been included at the insistence of the editor of the original memoir, but it cannot be taken seriously.

Note: My lovely and learned successor in office does not know what she is talking about. With the Senior, the most fantastic is always the most probable.

PRELUDE-I

As the door of the suite dilated, the man seated staring glumly out the window looked around. "Who the hell are you?"

"I am Ira Weatheral of the Johnson Family, Ancestor, Chairman Pro Tem of the Families."

"Took you long enough. Don't call me 'Ancestor.' And why just the Chairman Pro Tem?" the man in the chair growled. "Is the Chairman too damn busy to see me? Don't I rate even that?" He made no move to stand, nor did he invite his visitor to sit down.

"Your pardon, Sire. I am chief executive for the Families. But it has been customary for some time now-several centuries-for the chief executive to hold the title. 'Chairman Pro Tem'-against the possibility that you might show up and take the gavel."

"Eh? Ridiculous. I haven't presided at a meeting of the Trustees for a thousand years. And 'Sire' is as bad as 'Ancestor'-call me by name. It's been two days since I sent for you. Did you come by the scenic route? Or has the rule that entitles me to the ear of the Chairman been revoked?"

"I am not aware of that rule, Senior; it was probably long before my time-but it is my honor and duty-and pleasure-to wait on you at any time. I will be pleased and honored to call you by name if you will tell me what your name is now. As for the delay-thirty-seven hours since I received your summons-I have spent it studying Ancient English, as I was told that you were not answering to any other language."

The Senior looked slightly sheepish. "It's true I'm not handy with the jabber they speak here-my memory has been playing tricks on me lately. I guess I've been sulky about answering even when I understood. Names-I forget what name I checked in by when I grounded here. Mmm, 'Woodrow Wilson Smith' was my boyhood name. Never used it much. I suppose 'Lazarus Long' is the name I've used oftenest-call me 'Lazarus.'"
