Gorillas & Chimpanzees

In Short

This observational chronicle documents an ambitious, late-nineteenth-century quest to study anthropoid apes in their native habitat. By living in a custom-built steel cage in the forests of Gabon, the author records the daily behaviors, vocalizations, and temperaments of chimpanzees and gorillas, debunking popular myths about their nesting habits and social structures. The book serves as both a field report and a heartfelt defense of primate intelligence, seeking to elevate the reader’s understanding of these animals through anecdotal evidence and direct, unadorned observation.

The Story

The journey begins with an unconventional premise: that the best way to understand the closest biological relatives of man is to sit among them. Frustrated by the restricted, miserable conditions of apes in captivity, the narrator designs a portable steel-wire cage, painted green to blend into the foliage, and transports it to the dense tropical forests along the equator. His goal is to document their language—a task he approaches with the conviction that higher physical types possess more complex speech—and to observe their natural, unconstrained behavior.

The narrative shifts between the harsh realities of jungle life—insects, torrential storms, and the distant, haunting screams of wild gorillas—and the intimate, often tragic stories of the individual apes the author encounters. He details his time with Moses, a young chimpanzee whose intelligence and emotional capacity left a deep impression. The author describes Moses’s problem-solving skills, such as using a leaning bush to cross a stream, and the profound, heart-wrenching bond they shared. When the author leaves the jungle, Moses falls into a state of visible, lonely decline, only to be reunited with his human companion in his final, fading days.

The story also contrasts the gentle, social nature of chimpanzees with the volatility of others, such as the "shrewish" and obstinate chimpanzee Elisheba. Through these relationships, the author explores the immense variation in temperament among members of the same species. He further details his interactions with "Consul," a chimpanzee who exhibits a comical, human-like social awareness, including a preference for beer and coffee and an ability to use utensils.

As the account progresses, the focus turns toward the elusive gorilla. The author provides meticulous geographic details of their restricted habitat and challenges long-standing rumors, such as the idea that apes build permanent shelters or nests, which he insists he never once observed. He grapples with the mystery of jungle sounds, eventually concluding that the "drumming" attributed to the gorilla is actually the work of the chimpanzee. The narrative concludes with a sober reflection on the fragility of these animals, particularly noting the fatal effect of tobacco smoke on gorillas, and a final, humble assessment of his research. He acknowledges that while he has been forced to contradict previous scientific assumptions, he offers his findings not as a definitive, closed theory, but as a foundation for future students of nature to build upon.

How It Unfolds

The cage is constructed The author designs a collapsible steel-wire cubicle to ensure his safety while maintaining proximity to wild apes. This structure, which he carries into the heart of the Gabonese jungle, allows him to observe the forest without being noticed by the inhabitants.

A life among the leaves The narrative captures the atmosphere of the forest, alternating between the mundane routine of cooking over a fire and the nocturnal terror of hearing wild beasts nearby. He describes the daily struggle of the "universal chase for food" that defines the life of every creature in the wild.

The tragedy of companions The central emotional arc follows the lives of individual apes like Moses and Elisheba, documenting their unique personalities and his own role as a caregiver. These accounts illustrate the depth of their affection, their bouts of illness, and the grief they express during times of separation.

Scientific debunking The author systematically dismantles common myths, arguing that apes do not build nests and that the behaviors attributed to them by earlier travelers are often misidentified. He uses his own records of sound and behavior to challenge the existing consensus on how gorillas and chimpanzees communicate.

Reflections on the end The book concludes with the author’s return to civilization, where he shares observations of captive apes in England and Germany. He reflects on the limits of his own research and encourages a more sympathetic, scientific approach to understanding the minds of his subjects.

The People

The narrator serves as the primary lens through which the reader experiences the jungle; he is a patient, sensitive, and deeply empathetic observer who sees himself as a student rather than a conqueror. His goal is to "dignify the apes," a mission that often brings him into conflict with the hardened, superstitious views of the local traders and native hunters.

Moses, a young chimpanzee, acts as the emotional heart of the book. He represents the capacity for reason and profound attachment; his intelligence in solving physical puzzles and his lingering, soulful eyes when he is reunited with the narrator suggest a level of consciousness that challenges the boundaries between species.

Elisheba stands in sharp contrast to Moses. Described as "treacherous" and "sullen," she represents the diversity of temperament within a species. Her stubbornness and refusal to participate in the social play that Aaron, her companion, enjoys serve as evidence for the author’s argument that apes, like humans, possess individual character traits that defy simple generalizations.

Finally, Consul appears as the sophisticated, "well-disposed" urbanite of the ape world. With his comical wisdom and ability to navigate human social customs—like drinking beer or using a knife and fork—he highlights the adaptability of the chimpanzee and serves as the most vivid example of the potential for learning that the author believes exists within the genus.

In Its Own Voice

"The aim in view is to convey to the casual reader a more correct idea than now prevails concerning the physical, mental, and social habits of these apes."

The author establishes his primary goal in the preface, emphasizing his desire to replace popular myths with observed facts.

"He looked up and down the branch to see if there was any way to avoid it. He sat down on the bank, and declined to wade it."

The author describes the moment Moses, the chimpanzee, faces the simple, concrete problem of a stream he does not wish to cross.

"He would roll his dark brown eyes up and look into my face, as if to be assured that I had been restored to him."

This line captures the poignant, silent communication between the author and the dying Moses during the final days of his illness.

What It's Really About

The book is a sustained argument against the reductionist view of animals as mere biological automatons. By meticulously detailing the varied temperaments, social behaviors, and problem-solving abilities of his subjects, the author suggests that the line between human and ape is less of a wall and more of a continuum. The central question is whether the "dignifying" of the ape necessarily degrades the human; the author argues the opposite, proposing that acknowledging the capacity for thought and feeling in other creatures actually exalts humanity. He challenges the reader to move beyond "rash deductions" and to engage with the natural world through a lens of patient observation, sympathy, and a recognition of individual agency in all living things.

Why Read It Today

Readers who appreciate the Victorian spirit of scientific exploration—marked by both rugged personal endurance and a sincere, almost romantic curiosity—will find this book captivating. It feels like an intimate, handwritten field diary; the prose is remarkably clear and devoid of the dense jargon that characterizes much of the scientific writing of the 1890s. The author’s willingness to admit his own mistakes and his emotional vulnerability regarding his animal companions provide a warmth that makes the research feel deeply human.

However, a modern reader must be prepared for the period-specific attitudes, particularly the frequent reliance on the anecdotes of local native populations and the sometimes stark, clinical descriptions of the animals' illnesses and deaths. The narrative occasionally pauses for long, technical explanations of phonetic systems used to track animal sounds, which may test the patience of those interested only in the travelogue aspect. Despite these hurdles, the book remains a fascinating time capsule. It preserves a moment when the "great apes" were still largely mysterious, and the author’s plea for a more "sympathetic" relationship with nature remains as relevant now as it was at the turn of the century. It stays with you not because of its scientific accuracy, which has been surpassed, but because of the genuine, quiet bond it portrays between a man and his subjects.
