Five minutes later； the gorillas attacked。
The rain masked their approach； they seemed to burst out of nowhere； striking the fence from three directions simultaneously。 From that first moment； Elliot realized the attack would be unlike the others。 The gorillas had learned from the earlier assaults； and now were intent on finishing the job。
Primate attack animals； trained for cunning and viciousness： even though that was Elliot's own assessment； he was astonished to see the proof in front of him。 The gorillas charged in waves； like disciplined shock troops。 Yet he found it more horrifying than an attack by human troops。 lb them we are just animals； he thought。 An alien species； for which they have no feeling。 We are just pests to be eliminated。
These gorillas did not care why human beings were there； or what reasons had brought them to the Congo。 They were not killing for food； or defense； or protection of their young。
They were killing because they were trained to kill。
The attack proceeded with stunning swiftness。 Within seconds； the gorillas had breached the perimeter and trampled the mesh fence into the mud。 Unchecked； they rushed into the pound； grunting and roaring。 The driving rain matted their hair； giving them a sleek； menacing appearance in the red night lights。 Elliot saw ten or fifteen animals inside the pound； trampling the tents and attacking the people。 Azizi was killed immediately； his skull crushed between paddles。
Munro； Kahega； and Ross all fired laser bursts； but in the confusion and poor visibility their effectiveness was limited。 The laser beams fragmented in the slashing rain； the tracer bullets hissed and sputtered。 One of the RFSDs went haywire； the barrel swinging in wide arcs； bullets spitting out in all directions； while everyone dived into the mud。 Several gorillas were killed by the RFSD bursts； clutching their chests in a bizarre mimicry of human death。
Elliot turned back to the recording equipment and Amy flung herself on him； panicked； grunting in fear。 He pushed her away and switched on the tape replay。
By now the gorillas had overwhelmed everyone in the camp。 Munro lay on his back； a gorilla on top of him。… Ross was nowhere to be seen。 Kahega had a gorilla clinging to his chest as he rolled in the mud。 Elliot was hardly aware of the hideous scratching sounds now emanating from the loudspeaker； and the gorillas themselves paid no attention。
Another porter； Muzezi； screamed as he stepped in front of a firing RFSD； his frame shook with the impact。 of the bullets and he fell backward to the ground； his body smoking from the tracers。 At least a dozen gorillas were dead or lying。 wounded in the mud； groaning。 The haywire RFSD had run out of ammunition； the barrel swung back and forth； the empty chamber clicking。 A。 gorilla kicked it over； and it lay writhing on its side in the mud like a living thing as the barrel continued to swing。
Elliot saw one gorilla crouched over； methodically tearing a tent apart； shredding the silver MyLar into strips。 Across the camp； another arrival banged aluminum cook pans together； as if they were metal paddles。 More gorillas poured into the pound； ignoring the rasping broadcast sounds。
He saw a gorilla pass beneath the loudspeaker； very close； and pay no attention at all。 Elliot had the sickening realization that their plan had failed。
They were finished； it was only a matter of time。 A gorilla charged him； bellowing in rage； swinging stone paddles wide。 Terrified； Amy threw her hands over Elliot's eyes。 〃Amy！〃 he shouted； pulling her fingers away； expecting to feel at any moment the impact of the paddles and the instant of blinding pain。
He saw the gorilla hearing down on him。 He tensed his body。 Six feet away； the charging gorilla stopped so abruptly that he literally skidded in the mud and fell backward。 He sat there surprised； cocking his head； listening。
Then Elliot realized that the rain had nearly stopped； that there was now only a light drizzle sifting down over the campsite。 Looking across the pound； Elliot saw another gorilla stop to listen…then another…and another…and another。 The pound took on the quality of a frozen tableau； as the gorillas stood silent in the mist。
They were listening to the broadcast sounds。
He held his breath； not daring to hope。 The gorillas seemed uncertain； confused by the sounds they heard。 Yet Elliot sensed that at any moment they could arrive at some group decision and resume their attack with the same intensity as before。
That did not happen。 The gorillas stepped away from the people； listening。 Munro scrambled to his feet； raising his gun from the mud。 but he did not shoot； the gorilla standing over him seemed to be in a trance； to have forgotten all about the attack。
In the gentle rain； with the flickering night lights； the gorillas moved away； one by one。 They seemed perplexed； off balance。 The rasping continued over the loudspeaker。
The gorillas left； moving back across the trampled perimeter fence； disappearing once more into the jungle。 And then the expedition members were alone； staring at each other； shivering in the misty rain。 The gorillas were gone。
Twenty minutes later； as they were trying to rebuild their shattered campsite； the rain poured down again with unabated fury。
DAY 13： MUKENKO
June 25； 1979
1。 Diamonds
IN THE MORNING A FINE LAYER OF BLACK ASH covered the campsite； and in the distance Mukenko was belching great quantities of black smoke。 Amy tugged at Elliot's sleeve。
Leave now； she signed insistently。
〃No； Amy；〃 he said。
Nobody in the expedition was in a mood to leave； including Elliot。 Upon arising； he found himself thinking of additional data he needed before leaving Zinj。 Elliot was no
longer satisfied with a skeleton of one of these creatures； like men； their uniqueness went beyond the details of physical structure to their behavior。 Elliot wanted videotapes of the gray apes； and more recordings of verbalizations。 And Ross was more determined than ever to find the diamonds； with Munro no less interested。
Leave now。
〃Why leave now？〃 he asked her。
Earth bad。 Leave now。
Elliot had no experience with volcanic activity； but what he saw did not impress him。 Mukenko was more active than it had been in previous days； but the volcano had ejected smoke and gas since their first arrival in Virunga。
He asked Munro； 〃Is there any danger？〃
Munro shrugged。 〃Kahega thinks so； but he probably just wants an excuse to go home。〃
Amy came running over to Munro raising her arms； slapping them down on the earth in front of him。 Munro recognized this as her desire to play； he laughed and began to tickle Amy。 She signed to him。
〃What's she saying？〃 Munro asked。 〃What are you saying； you little devil？〃
Amy grunted with pleasure； and continued to sign。
〃She says leave now；〃 Elliot translated。
Munro stopped tickling her。 〃Does she？〃 he asked sharply。 What exactly does she say？〃
Elliot was surprised at Munro's seriousness…although Amy accepted his interest in her munication as perfectly proper。 She signed again； more slowly； for Munro's benefit； her eyes on his face。
〃She says the earth is bad。〃
〃Hmm；〃 Munro said。 〃Interesting。〃 He glanced at Amy and then at his watch。
Amy signed； Nosehair man listen Amy go home now。
〃She says you listen to her and go home now；〃 Elliot said。
Munro shrugged。 〃Tell her I understand。〃
Elliot translated。 Amy looked unhappy； and did not sign again。
〃Where is Ross？〃 Munro asked。
〃Here；〃 Ross said。
〃Let's get moving；〃 Munro said； and they headed for the lost city。 Now they had another surprise…Amy signed she was ing with them； and she hurried to catch up with them。
This was their final day in the city； and all the participants in the Congo expedition described a similar reaction： the city； which had been so mysterious before； was somehow stripped of its mystery。 On this morning； they saw the city for what it was： a cluster of crumbling old buildings in a hot stinking unfortable jungle。
They all found it tedious； except for Munro。 Munro was worried。
Elliot was bored； talking about verbalizations and why he wanted tape recordings； an
