〃In the male parent the intervention presents no theoretical problem but would be difficult because the cells are very small…but I would not hesitate to attempt it given time to construct the necessary fine extensionals。
〃The logical place to start； both parents； would be with gonia placed in vitro； and cherished。 When a spermatogonium was observed to change to a primary spermatocyte…still diploid…it would be segregated and at the instant it divided into two secondary spermatocytes…haploids； one with an X chromosome and one with a Y chromosome…they would be again segregated and each would be encouraged to develop into spermatozoa。
〃It would not be sufficient to intervene at the spermatozoa stage； confusion of gamete pairs could not be avoided； and resulting zygotes could be plementary only by wildest chance。
〃Intervention with the female parent is mechanically simpler because of larger cells…but involves a different problem； the primary oocyte must be encouraged； at point of meiosis； to produce two haploid and plementary secondary oocytes； rather than one oocyte and one polar body。 Lazarus； this might require many attempts before a reliable technique could be worked out。 It would be similar to the process of identical twinning but must take place two stages earlier in the gametogeic sequence。 However； it might turn out to be no more difficult than it is to produce fatherless female rabbits。 I do not venture an opinion as I lack former art to draw dn…save that I feel certain that it can be done； given time to。 develop technique。
〃At this point we have plementary groups of spermatozoa； one group with Y and one with X； and a plementary pair of ova； each with an X chromosome。 Fertilization would be in vitro； with a possibility of choosing either of two potential pairs of female…male plements… but with no basis for choice unless the geic charts of haploids are determined precisely； which is difficult and likely to cause geic damage； I do… not think it would be attempted。 Instead one sperm would be inserted into one ovum； its plement into the other； on a blind basis。
〃One last requirement must be met to justify all of this slave factor's allegations： The two fertilized ova must be removed from vitro and planted in the womb of the donor of the oogonium； and there allowed to develop as twins through natural gestation and birth。
〃Am I right； Lazarus？〃
〃Exactly right！ Go to the head of the class； dear； you get a gold star on your report card。 Minerva； I don't know that it happened that way。 But that's what the factor claimed； and that's what his exhibits…lab reports； holo…movies； and so forth…seemed to show。 But that thief may have faked those 〃proofs〃 and offered a random pair not likely to fetch a price above average…save for his fancy sales talk。 The so…called proofs looked good； and lab reports and such carried a bishop's chop and seal。 The stills and movies looked good； too…but how can a layman judge？ Even if those exhibits weren't phony； all they could prove was that such a process had once taken place； they did not prove that these kids were the result。 Shucks； they might have been used to sell many slave pairs； with a bishop in on the racket。
I looked over the stuff； including a scrapbook of the kids growing up； said； 〃Very interesting；〃 and started to leave。
This pimple teleported himself between me and the tent flap。 〃Master；〃 he said urgently。 〃Kind and generous sir… twelve thousand？〃
Minerva； my trader instincts took over。 〃One thousand！〃 I snapped。 I don't know why。 Yes； I do know。 The girl's body was scarred from that damned Torquemada girdle； I wanted to insult this flesh peddler。
He flinched and looked as if he were giving birth to broken beer bottles。 〃You jest with me。 Eleven thousand blessings； and they are yours…though I won't make expenses！〃
〃Fifteen hundred；〃 I answered。 I bad money I couldn't spend elsewhere and told myself I could afford to manumit them rather than let that girl be bound into that damned atrocity again。
He moaned。 〃If they were mine； I would give them to you。 I love these cute darlings like my own children and could ask for them nothing better tha？ a kind and gentle master learned in science who appreciates the wonders that have gone into
their making。 But the Bishop would hang me and have me cut down alive to be dragged to death by my tool。 Ten thousand and take all proofs and exhibits。 I'~ll suffer a loss for their sakes…and because I admire you so much。〃
I got up to forty…five hundred and he got down to seven thousand and there we stuck； as I had to hold out cash for last…minute squeeze； whereas it felt to me that he was close to ：the point where he really could not sell without risking the Bishop's wrath。 If there was a bishop。 。 。
He turned away in a fashion that says that a dicker is over and he is through flattering you； and told the girl sharply to step back inth her steel harness。
I got out my purse。 Minerva； you understand money； you handle the government's finances。 But possibly you don't know that cash money affects some people the way catnip does Diablo~ I counted out forty…five hundred blessings in big red…and…gold bills under that scoundrel's nose…and stopped。 He was sweating and swallowing his Adam's apple but managed to shake his head a tenth of an inch。
So I counted more bills； very slowly； and reached five thousand…then started briskly to pick them up。
He stopped … me…and I found that I had bought the only slaves I have ever owned。
He relaxed then； in a resigned way； but wanted ***lagniappe*** for the exhibits。 I didn't care one way or another but offered two hundred and fifty for the pix and tapes； take it or leave it。 He took it and again started to put the girl back into her harness。
I stopped him and said； 〃Show me how that works。〃
I knew how a cylinder…type ten…letter bination lock you could set to a new bination each time you used it。 Set the bination； slide the ends of the steel strap that went around her waist through the ends of the barrel； spin the alphabet disks of the cylinder； then it stays locked until you reset whatever ten…letter bo you picked。 An expensive lock… and good steel in the girdle…alloy a hacksaw couldn't touch。 This was another thing that made his story convincing； as； while there was a market for virgins on that weird globe； a trained odalisque fetched about the same； and this girl wasn't being reserved for harem stock either way。 So an expensive custom…made chastity belt had to have some other reason。
With our backs to the slaves he showed me the bination： E；S；T；R；E；L；L；I；T；A…and was smug about how clever he was to pick a bination he couldn't forget。
So I fumbled on purpose； then pretended to catch on； and opened it。 He was about to put it on the kid again and send us on our way。 I said； 〃Wait a moment。 I want to be sure I can work it in place。 You step into it and let me get you out of it。〃
He didn't want to。 So I got snotty and said he was trying to cheat me…put me in a position where I would have to send for him and pay through the nose to get my property unlocked。 I demanded my money back and started to tear up the bill of sale。 He gave in and stepped into the contrivance。
He could squeeze into it although the ends of the steel belt barely met； he was bigger around the waist than the girl was。 I said； 〃Now spell that bination for me〃…and leaned over the lock。 As he spelled 〃ESTRELLITA；〃 what I set was 〃HORSETHIEF'；〃 then iammed the ends together as hard as possible and spun the disks。
〃Good；〃 I said。 〃It works。 Now spell it again。〃
He did so and I carefully spelled 〃ESTRELLITA。〃 It stayed locked。 I suggested that he bad had me spell it with one 1 and two t's the first time。 That didn't work either。
He dug up a mirror and tried it himself。 No go。 I said it might be jammed； so suck up your gut and we'll shake it。 By now he was sweating。
Finally I said； 〃Tell you what； goodman…I'll give you this belt。 I'd rather trust a p
