Summary

The chapter opens with Seth cooking trout over a wood-burning stove in the butte dwelling he shares with the Professor. A gust of dry desert air announces the Professor's return from his lab. The Professor looks exhausted, his white hair disheveled and his button-down shirt flecked with dried blood. He collapses onto the couch, tosses a sheaf of papers onto the coffee table, and swallows a handful of tablets from a pill bottle. When Seth asks if he's hungry, the Professor grumbles and then asks whether Seth plans to check the pit that day. Seth says he was thinking tomorrow, but the Professor insists it must be today, adding that he needs another subject, preferably a female. Seth asks why, but the Professor dismisses him with a look, simply saying, “Just bring me a female.” Seth notes that he has no control over what gets trapped, and the Professor reminds him to keep his guard up.

Seth eats half the fish at the kitchen counter and brings the other half to the Professor, but the Professor has already fallen asleep on the couch, snoring loudly. Seth observes that the Professor has been rationing his supplements—nicotinamide riboside, a precursor to NAD+—and that he still sleeps fifteen or sixteen hours a day. Seth leaves the plate on the coffee table, knowing it will likely remain untouched.

In his room, Seth retrieves his “stink box,” a sealed cube containing unwashed green cargo pants, a tan T-shirt, his dead father's belt, and bundles of sage. He explains that he has never washed these clothes in a decade of desert travel, allowing his body odor to saturate the fabric and blend in with the Andes' musk. The Professor is repelled by the smell, hence the box and sage. Seth pulls on the clothes, noting they are tight and are hand-me-downs from the Professor. He then applies a thick layer of mica-dominated clay to his face, neck, and forearms to protect from the sun and to make himself look more like the creatures he hunts. He rubs clay into his hair as well.

After strapping on his boots, sheathing his knife, and grabbing his pack and short bow, Seth heads outside. It's only half past ten and already blistering. He reflects on the Professor's claim that global warming became a thing of the past once Andes became the torchbearers for human DNA, but Seth disagrees—it's the hottest June he can remember. He walks to the edge of the butte, where a winch system lowers a steel platform. He looks out over the gray and red maze of canyons, washes, and mesas. He begins box breathing to clear his mind, but his thoughts keep drifting to the Professor's secret experiments, which have sent him on twice as many hunting expeditions in the past year. He wishes he could return to simpler times when the desert was his playground, but now he feels stifled by its vast emptiness and longs for the world beyond.

After saying “Screw it,” Seth places his bow and backpack on the platform and cranks it down sixty feet. He then begins descending the vertical cliff face.

Three miles from the butte, Seth cautiously approaches the edge of a small canyon, about thirty feet deep and seventy across, with sheer walls that prevent escape. He listens and hears nothing but the breeze, then tosses a rock over the edge. It plunks into a creek below, followed by the signature grunts of Andes—short, guttural barks that sound like a rudimentary language. Seth whispers “Jackpot.”

He kneels, unshoulders his bow, and places it with his nine arrows. He then pulls out his trumpet, which he calls the most valuable weapon in his arsenal. He flattens onto his stomach and crawls forward, repeating a mantra from his early years: “Their bodies are human, but their brains are not. One wrong step, and you'll be the one caught.”

Peeking over the edge, he sees four Andes—two adult females and two younglings—sitting around the fifteen-foot-deep pit he dug when he was fourteen. One of the younglings tosses chunks of raw rabbit meat into the pit, where a trapped Ande wails. Seth notes that the Andes seem advanced: they have hollowed-out gourds as canteens, which is a first. He reflects on his theory that they are evolving, though the Professor dismisses such assumptions without proof. The Professor claims that since Advitalon ravaged their minds, some groups may be latching onto ancient instinctive knowledge. Seth isn't sure what to believe, but he notes they still can't recognize a trap.

The trapped creature is likely an alpha male, as most bands have one and they are usually the first to investigate something curious. The piles of small bones suggest the band has been there for days. Seth knows the Professor wants a female, but he'll have to make do with the alpha.

As the adult females hover around the pit, one tosses her dreadlocked hair over her shoulder—a strangely human gesture. Seth momentarily imagines her in a dress, seeing a woman, but then she scratches her mangy hair and reveals broken brown teeth, reminding him they are not human.

After checking for other Andes, Seth takes a deep breath and blows into the trumpet, hammering all three valves and extending the tuning slide to create an unbearable noise. The four Andes scatter, running in confusion as the sound bounces off the canyon walls. The boy shits himself as they flee. Seth follows them along the ridgeline, occasionally blasting the trumpet to ensure they don't turn back. He shadows them for half a mile until they reach open desert and become specks on the horizon. Then he climbs down to retrieve the trapped alpha, heading back toward the Professor's prize.

Key Events

The Professor returns from his lab, blood-flecked and exhausted, and demands that Seth check the pit that day and bring back a female Ande.
Seth prepares for the hunt by donning unwashed clothes, applying clay to his skin and hair, and gathering his bow, knife, and trumpet.
He descends from the butte via a winch platform and climbs down the cliff face.
At a canyon three miles away, he discovers four Andes gathered around a pit he dug earlier, with one Ande trapped inside.
He uses a trumpet to create a loud, disorienting noise, scaring the group away.
He follows the fleeing Andes along the ridgeline until they are far off, then climbs down to retrieve the trapped alpha male—not the female the Professor requested.

Character Development

Seth is the narrator and protagonist. This chapter deepens his internal conflict. He is skilled and resourceful, but he feels trapped by his isolated life on the butte. He longs for the world beyond, yet he knows he is marooned there. His resentment toward the Professor's experiments grows, and he questions the Professor's authority. He also shows a nuanced view of the Andes: he recognizes their human-like gestures and potential evolution, but he ultimately sees them as non-human and dangerous. His decision to bring back the alpha instead of the female—despite the Professor's explicit request—shows a quiet defiance and a practical acceptance of what the trap yields.

The Professor is physically declining, as evidenced by his blood-flecked shirt, his reliance on supplements, and his excessive sleep. He is secretive about his experiments, refusing to explain why he needs a female subject. His dismissive attitude toward Seth's questions reinforces the power imbalance between them. Despite his frailty, he still commands Seth's obedience, though Seth's compliance is reluctant.

Themes, Symbols, or Motifs

Human vs. non-human boundary: Seth constantly reminds himself that Andes are not human, even when they display human-like behaviors. The chapter blurs this line, especially when Seth imagines the female Ande in a dress, only to be snapped back by her vacant eyes and broken teeth.
Isolation and confinement: Seth is physically isolated on the butte and emotionally confined by his duty to the Professor. The desert is both his playground and his prison.
Camouflage and deception: Seth's stink box, clay disguise, and trumpet are tools of deception. He uses them to blend in with the environment and to manipulate the Andes' behavior.
Professor's declining health: The Professor's reliance on supplements and his long sleeps symbolize his fading vitality and the unsustainable nature of his experiments.
Longing for the world beyond: Seth's thoughts repeatedly drift to the mysteries of the outside world, contrasting with his current life of trapping and survival.
Evolution and instinct: The Andes' use of gourds as canteens suggests a possible evolution or reawakening of instinctive knowledge, a theme that will likely develop further.

Why This Chapter Matters

This chapter establishes the core dynamic between Seth and the Professor, revealing the Professor's secretive experiments and Seth's growing dissatisfaction. It introduces the practical mechanics of trapping Andes, showing Seth's expertise and the dangers involved. The chapter also plants seeds for future conflict: Seth's defiance in bringing back an alpha instead of a female, his curiosity about the Andes' evolution, and his longing for escape. The Professor's declining health hints at a ticking clock, while the Andes' apparent advancement raises questions about the nature of humanity and the consequences of the Professor's work.

Study Questions and Answers

Why does Seth decide to bring back the alpha male instead of the female the Professor requested?

Seth has no control over what gets trapped. The alpha male was the one who fell into the pit, and the band had already been there for days. Seth knows the Professor will have to make do with what he gets. His decision is practical, but it also reflects a quiet defiance—he doesn't go out of his way to fulfill the Professor's specific demand.

How does Seth's preparation for the hunt reveal his relationship with the Professor?

Seth uses a “stink box” with unwashed clothes and sage to mask his scent, and he applies clay to his skin and hair. These preparations show his deep knowledge of the desert and his commitment to survival. However, the fact that he must hide these clothes from the Professor because the Professor is repelled by the smell highlights the tension between them. Seth's routine is built around the Professor's needs, yet he also maintains his own independence.

What evidence in this chapter suggests that the Andes might be evolving?

Seth observes that the Andes have hollowed-out gourds as canteens, which is a first. He also notes their use of clubs and their ability to work together to try to free their trapped packmate. The Professor dismisses these observations as assumptions without proof, but Seth's theory is based on direct evidence. The chapter leaves this question open, inviting the reader to wonder about the Andes' potential development.
