Travels in the Interior of Brazil: Principally through the northern provinces, and the gold and diamond districts, during the years 1836-1841

In Short

Travels in the Interior of Brazil is George Gardner’s detailed personal account of his five-year scientific expedition across the Brazilian provinces from 1836 to 1841. Sent to collect botanical specimens for British institutions, Gardner journeys from the coastal hubs of Rio de Janeiro and Pernambuco into the remote interior, traversing arid scrublands, river basins, and mountain ranges to reach the famous gold and diamond districts. Along the way, he collects thousands of uncataloged plants while carefully recording the physical geography, agricultural practices, social structure, and institution of slavery. The book remains a valuable historical document for its blend of rigorous empirical observation and vivid first-hand reportage on nineteenth-century South America.

The Story

George Gardner arrives in Rio de Janeiro in 1836 as a young natural scientist seeking to explore lands largely unmapped by British botanists. He begins his work by using the coastal metropolis as a base, making shorter excursions into the surrounding countryside. He climbs into the Organ Mountains, staying at the estate of a local English merchant to collect high-altitude flora. These early trips introduce him to the dense tropical forests, where he employs local guides to cut paths through massive bamboo thickets and ascending mountain ridges.

Seeking broader horizons, Gardner sails north along the coast to Pernambuco and Ceará. He uses coastal ports like Olinda and Aracaty as staging grounds, organizing pack trains of horses to carry equipment, food, and plant presses into the interior. Moving west from the coast, he enters the dry backlands known as the Sertão. The landscape turns harsh and arid, dominated by thorny scrub, fleshy cacti, and stands of drought-resistant palms. Heat and scarcity of water make travel difficult, forcing his small party to move during early morning hours and rest in roadside sheds or under shade trees during the hottest parts of the day.

Despite these hardships, Gardner continues deeper into the province of Piauhy, reaching its capital, Oeiras. His plans to press further north are disrupted by a local armed insurrection, forcing him to alter his route. Adapting to the danger, he turns south toward the central highlands, riding through the provinces of Goyaz and Minas Geräes. This long overland journey takes him across vast tablelands called Chapadas, over flooded rivers where baggage must be ferried on the heads of local workers, and through isolated cattle ranches.

As Gardner enters Minas Geräes, the geography shifts from scrubby plains to mineral-rich mountains. Here he explores the gold and diamond mining districts that made the region famous. He visits active operations, such as the Morro Velho gold mine, where he dons flannel and canvas clothes to descend nearly four hundred feet into subterranean galleries to observe how the ore is extracted. Throughout these travels, Gardner maintains a disciplined routine: pressing plants, drying paper, keeping a log of atmospheric conditions, and noting geological formations, including chalk and sandstone deposits that parallel European strata.

His return journey leads him back down toward the Atlantic coast, navigating dense forests, rivers, and coffee plantations. He experiences unpredictable tropical storms that flood overnight shelters and damage carefully preserved specimens, but he successfully transports his collection back to Rio de Janeiro. By the end of his five-year journey in 1841, Gardner has gathered thousands of plant specimens—many new to European science—and compiled a comprehensive picture of Brazil’s interior before embarking for home.

How It Unfolds

The arrival at Rio Gardner lands in Brazil in 1836 and establishes a base in Rio de Janeiro, making initial botanical excursions into the surrounding bay, islands, and coastal forests to study local flora and marine life.

Into the Organ Mountains Accompanying an English merchant, Gardner climbs into the high peaks of the Organ Mountains, establishing a camp to collect high-altitude plants and exploring paths through massive bamboo thickets guided by an elderly Creole hunter named Pai Felipe.

Northward to the Sertão Sailing up the coast to Pernambuco and Ceará, Gardner equips a horse troop in Aracaty and rides inland, entering the hot, arid backlands where he gathers native fruits like the Mangába and documents the uses of the Carnahuba palm.

Crossing Piauhy and turning south Upon reaching Oeiras, the provincial capital, Gardner encounters political instability and a regional revolt; he adapts by redirecting his trek south through Goyaz, crossing hazardous rivers and vast cattle farms.

The diamond and gold country Entering Minas Geräes, Gardner inspects the mountain ranges and mining networks of the region, descending deeply into the Morro Velho gold mine to study its geological structures and operational layout.

Return to the coast Navigating dense virgin forests, mountain descents, and sudden tropical tempests that threaten his botanical collections, Gardner makes his way back toward the eastern ports to prepare his massive herbarium for shipment to Great Britain.

The People

George Gardner The author and narrator, a dedicated Scottish botanist and physician. Driven by a desire to explore regions unvisited by previous naturalists, he endures harsh weather, physical exhaustion, and treacherous terrain to collect, catalogue, and preserve thousands of rare plant specimens.

Sir William Jackson Hooker The Director of the Royal Gardens at Kew, to whom the book is dedicated. As Gardner’s mentor and patron, his encouragement and institutional backing make the entire five-year South American expedition possible.

Mr. March An English merchant living near Rio de Janeiro who owns an estate in the Organ Mountains. He provides Gardner with a base of operations, hospitality, and local knowledge during his initial mountain collecting trips.

Pai Felipe A Creole hunter over sixty years old who acts as Gardner's guide in the Organ Mountains. Raised in the forest, his agility and deep knowledge of the woods allow the expedition to clear paths through dense bamboo and reach unexplored peaks.

Dr. Serpa An agreeable sixty-year-old physician and professor who oversees the Botanic Garden in Olinda. He provides Gardner with living specimens of native medicinal plants, including a local species of Ipecacuanha, to send back to Scottish botanical gardens.

Barão de Parnahiba The powerful President of the Province of Piauhy, residing in the capital city of Oeiras. His dominance over the region and the political upheaval surrounding his rule shape the security conditions of Gardner's travel through the northern interior.

Virgil Von Helmreichen A civil engineer working in the mining district of Minas Geräes. Recognizing the financial difficulties of remote travel, he generously offers to lend Gardner funds without security to ensure he can complete his journey back to the coast.

In Its Own Voice

“I have frequently tasted it, but always found it so nauseous that the most urgent thirst alone would compel me to drink it.”

Gardner describes the liquid found inside the internodes of giant bamboos in the Organ Mountains, contradicting previous travelers who praised it as a delicious beverage.

“It was impossible not to conclude that the actions of this little creature, which holds so low a station in the chain of beings, were the result of reason, rather than of blind instinct...”

While resting on a beach, Gardner observes a small burrowing crab methodically clearing away the small shells he tossed into its hole, marveling at its apparent problem-solving ability.

“In Brazil, when iron was put into the water it always sank.”

A provincial president responds with polite skepticism when Gardner explains that modern English steamships are constructed entirely of iron rather than wood.

What It's Really About

At its core, Travels in the Interior of Brazil is an investigation into the natural systems and human structures of a rapidly changing country. While structured around botanical exploration, the narrative constantly examines the relationship between land, economy, and society. Gardner documents how climate and geography dictate human settlement, contrasting the fertile, moisture-rich mountain zones with the scorched, desert-like interior where survival depends on drought-resistant flora and cattle driver skill.

The book also presents a candid assessment of Brazilian institutions in the post-independence era. Gardner pays special attention to the system of slavery, noting its demographic ratios, economic necessity to plantation owners, and the ongoing illegal slave trade despite statutory bans. Rather than relying on secondhand hearsay, he records direct observations regarding labor conditions in mines, fields, and urban centers. Beneath its scientific cataloging of species and geological strata, the work functions as an empirical portrait of a nation’s natural wealth alongside its social vulnerabilities.

Why Read It Today

Travels in the Interior of Brazil appeals to readers who appreciate classic travel literature, environmental history, and direct, unvarnished field reportage. Gardner writes with the steady clarity of a trained scientific observer, avoiding dramatic sensationalism in favor of precise detail. His prose captures the daily reality of nineteenth-century exploration: the quiet satisfaction of discovering a new orchid species, the practical logistics of keeping horses alive in a drought, and the social interactions enjoyed under the shade of a village tree.

The book does present specific reading challenges typical of its era. Its length is substantial, and the text includes frequent botanical nomenclature, detailed lists of plant families, and technical geological classifications. Readers must also navigate nineteenth-century colonial attitudes and terminology when Gardner discusses race, social class, and slavery, though his observations are generally more measured and evidence-based than those of many contemporary visitors.

What stays with the reader is the sheer scope of Gardner's journey and his quiet resilience. Whether sleeping on raw hides during a mountain gale, wading through flooded rivers, or describing the delicate white flowers of an Eriocaulon high on a rocky ridge, Gardner conveys the authentic texture of a world on the cusp of modern development. It remains a deeply grounded, informative account for anyone curious about the natural history and early political landscape of South America.
