omptly began making demands。
She was unhappy to learn that they had not acquired milk or cookies in her absence； but when Munro produced the bottle of warm Dom Perignon； she agreed to accept champagne instead。
They all sat around her； drinking champagne from tin cups。 Elliot was glad for the mitigating presence of the others； for now that Amy was sitting there； safely restored to him； calmly sipping her champagne and signing Tickle drink Amy like； he found himself overe with anger toward her。
Munro grinned at Elliot as he gave him his champagne。 〃Calmly； Professor； calmly。 She's just a child。〃
〃The hell she is；〃 Elliot said。 He conducted the subsequent conversation entirely in sign language； not speaking。
Amy； he signed。 Why Amy leave？
She buried her nose in her cup； singing Tickle drink good drink。
Amy； he signed。 Amy tell Peter why leave。
Peter not like Amy。
Peter like Amy。
Peter hurt Amy Peter fly ouch pin Amy no like Peter no like Amy Amy sad sad。
In a detached corner of his mind； he thought he would have to remember that 〃ouch pin〃 had now been extended to the Thoralen dart。 Her generalization pleased him； but he signed sternly； Peter like Amy。 Amy know Peter like Amy。 Amy tell Peter why… Peter no tickle Amy Peter not nice Amy Peter not nice human person Peter like woman no like Amy Peter not like Amy Amy sad Amy sad。
This increasingly rapid signing was itself an indication that she was upset。 Where Amy go？
Amy go gorillas good gorillas。 Amy like。
Curiosity overcame his anger。 Had she joined a troop of wild gorillas for several days？ If so； it was an event of major importance； a crucial moment in modern primate history… a language…skilled primate had joined a wild troop and had e back again。 He wanted to know more。
Gorillas nice to Amy？
With a smug look： Yes。
Amy tell Peter。
She stared off into the distance； not answering。
To catch her attention Elliot snapped his fingers。 She turned to him slowly； her expression bored。
Amy tell Peter； Amy stay gorillas？
Yes。
In her indifference was the clear recognition that Elliot was desperate to learn what she knew。 Amy was always very astute at recognizing when she had the upper hand…and she had it now。
Amy tell Peter； he signed as calmly as he could。
Good gorillas like Amy Amy good gorilla。
That told him nothing at all。 She was posing phrases by rote： another way of ignoring him。
Amy。
She glanced at him。
Amy tell Peter。 Amy e see gorillas？
Yes。
Gorillas do what？
Gorillas sniff Amy。
All gorillas？
Big gorillas white back gorillas sniff Amy baby sniff Amy all gorillas sniff gorillas like Amy。
So silverback males had sniffed her； then infants； then all the members of the troop。 That much was clear…remarkably clear； he thought； making a mental note of her extended syntax。 Afterward had she been accepted in the troop？ He signed； What happen Amy then？
Gorillas give food。
What food？
No name Amy food give food。
Apparently they had shown her food。 Or had they actually fed her？ Such a thing had never been reported in the wild； but then no one had ever witnessed the introduction of a new animal into a troop。 She was a female； and nearly of productive age。
What gorillas give food？
All give food Amy take food Amy like。
Apparently it was not males； or males exclusively。 But what had caused her acceptance？ Granted that gorilla troops were not as closed to outsiders as monkey troops…what actually had happened？
Amy stay with gorillas？
Gorillas like Amy。
Yes。 What Amy do？
Amy sleep Amy eat Amy live gorillas gorillas good gorillas Amy like。
So she had joined in the life of the troop； living the daily existence。 Had she been totally accepted？
Amy like gorillas？
Gorillas dumb。
Why dumb？
Gorillas no talk。
No talk sign talk？
Gorillas no talk。
Evidently she had experienced frustration with the gorillas because they did not know her sign language。 （Language using primates were monly frustrated and annoyed when thrown among animals who did not understand the signs。）
Gorillas nice to Amy？
Gorillas like Amy Amy like gorillas like Amy like gorillas。
Why Amy e back？
Want milk cookies。
〃Amy；〃 he said； 〃you know we don't have any damn milk or cookies。〃 His sudden verbalization startled the others。 They looked questioningly at Amy。
For a long time she did not answer。 Amy like Peter。 Amy sad want Peter。
He felt like crying。
Peter good human person。
Blinking his eyes he signed； Peter tickle Amy。 She jumped into his arms。
Later； he questioned her in more detail。 But it was a painstakingly slow process； chiefly because of Amy's difficulty in handling concepts of time。
Amy distinguished past； present； and future…she remembered previous events； and anticipated future promises…but the Project Amy staff had never succeeded in teaching her exact differentiations。 She did not； for example； distinguish yesterday from the day before。 Whether this reflected a failing in teaching methods or an innate feature of Amy's conceptual world was an open question。 （There was evidence for a conceptual difference。 Amy was particularly perplexed by spatial metaphors for time； such as 〃that's behind us〃 or 〃that's ing up。〃 Her trainers conceived of the past as behind them and the future ahead。 But Amy's behavior seemed to indicate that she conceived of the past as in front of her…because she could see it…and the future behind her… because it was still invisible。 Whenever she was impatient for the promised arrival of a friend； she repeatedly looked over her shoulder； even if she was facing the door。）
In any case； the time problem was a difficulty in talking to her now； and Elliot phrased his questions carefully。 He asked； 〃Amy； what happened at night？ With the gorillas？〃
She gave him the look she always gave him when she thought a question was obvious。 Amy sleep night。
〃And the other gorillas？〃 Gorillas sleep night。
〃All the gorillas？〃 She disdained to answer。
〃Amy；〃 he said； 〃gorillas e to our camp at night。〃 e this place？
〃Yes； this place。 Gorillas e at night。〃
She thought that over。 No。 Munro said； 〃What did she say？〃
Elliot said； 〃She said 'No。' Yes； Amy； they e。〃
She was silent a moment； and then she signed； Things e。
Munro again asked what she had said。
〃She said； 'Things e。' 〃 Elliot translated the rest of her responses for them。
Ross asked； 〃What things； Amy？〃
Bad things。
Munro said； 〃Were they gorillas； Amy？〃
Not gorillas。 Bad things。 Many bad things e forest e。 Breath talk。 e night e。
Munro said； 〃Where are they now； Amy？〃
Amy looked around at the jungle。 Here。 This bad old place things e。
Ross said； 〃What things； Amy？ Are they animals？〃 Elliot told them that Amy could not abstract the category 〃animals。〃 〃She thinks people are animals；〃 he explained。 〃Are the bad things people； Amy？ Are they human persons？〃
No。
Munro said； 〃Monkeys？〃
No。 Bad things。 not sleep night。
Munro said； 〃Is she reliable？〃
What means？
〃Yes；〃 Elliot said。 〃Perfectly。〃
〃She knows what gorillas are？〃
Amy good gorilla； she signed。
〃Yes； you are；〃 Elliot said。 〃She's saying she's a good gorilla。〃
Munro frowned。 〃So she knows what gorillas are； but she says these things are not gorillas？〃
〃That's what she says。〃
2。Missing Elements
ELLIOT GOT ROSS TO SET UP THE VIDEO CAMERA AT the outskirts of the city； facing the campsite。 With the videotape running he led Amy to the edge of the camp to look at the ruined buildings。 Elliot wanted to confront Amy with the lost city； the reality behind her dreams…and he wanted a record of her responses to that moment。 What happened was totally unexpected。
Amy had no reaction at all。
Her face remained impassive； her body relaxed。 She did not sign。 If anything she gave the impression of boredom； of suffering through another of Elliot's enthusiasms that she did not share。 Elliot watched her carefully。 She wasn't displacing； she wasn't repressing； she wasn't doing anything。 She stared at the city with equanimity。
〃Amy know this place？〃
Yes。
〃Amy tell Peter what place。〃 Bad place old place。
〃Sleep pictures？〃 This bad place。
〃Why is it
