The Naturalist on the River Amazons — A Reader’s Guide

The Masonry of Stingless Bees

Bates devotes sustained attention to the Meliponæ, the stingless bees of the Amazon, and his account of their nest-building is a model of patient description. He notes that most species are 'masons as well as workers in wax,' using clay to seal crevices in trees. One tiny species, 'not more than two lines long,' constructs a tubular gallery with a trumpet-shaped mouth, outside which 'a number of pigmy bees are always stationed, apparently acting as the sentinels.' The observation is precise enough to be useful to an entomologist, yet it also carries a hint of wonder at the social organization of these minute creatures.

When a hive of Melipona fasciculata is opened, Bates records that it contained 'about two quarts of pleasant-tasting liquid honey.' The Indian who plundered it was 'completely covered' by the bees, which 'took a particular fancy to the hair of his head, and fastened on it by hundreds.' The detail is characteristic: Bates does not flinch from the discomfort of fieldwork, but he reports it without self-dramatization. He also notes that he found forty-five species of these bees across the region, ranging from half an inch in length to the tiniest forms. The variety itself becomes a kind of argument for the richness of the Amazonian environment.

The Limits of Exploration

Despite his evident curiosity, Bates repeatedly acknowledges the boundaries of his travels. In the Santarem region, his rambles 'never extended further than the banks of the Irurá,' a stream that rises among hills and flows through a broad valley before joining the Tapajos. Beyond that point, he writes, 'all beyond, as before remarked, is terra incognita to the inhabitants of Santarem.' The Brazilian settlers, he observes, 'seem to have no taste for explorations by land,' and he could find no one willing to accompany him further inland. A journey would be 'exceedingly difficult,' and there were reports of 'a settlement of fierce runaway negroes on the Serra de Mururarú,' making it unsafe to go far without a large armed party.

These passages are valuable precisely because they do not pretend to omniscience. Bates is candid about the practical and social obstacles that shaped his fieldwork. He did not reach the summit of the Pico do Irura, a conical hill rising 500 or 600 feet, because the ascent was 'excessively fatiguing' and the hillside was clothed in 'a dense growth of coarse grasses.' The narrative thus preserves the texture of a real expedition, with its frustrations and compromises, rather than offering a heroic tale of conquest.

Contrasts of Landscape and Light

Bates's descriptive eye is drawn to sharp juxtapositions. The forest brooks he visited—the Irurá, the Panéma, the Urumarí—are praised for their 'clear, cold waters brawling over their sandy or pebbly beds through wild tropical glens.' He finds 'great charm' in these 'moist, cool, and luxuriant glades,' and he heightens their appeal by contrasting them with the 'sterile country around them.' The surrounding hills are 'bare or scantily wooded,' parched by the vertical sun, and the walk from Santarem to the Pico do Irura crosses 'campos' that offer no shade.

This technique of contrast is not merely rhetorical; it reflects the actual patchwork of Amazonian ecosystems. Bates notes that the beauty of the glades 'was heightened by the contrast they afforded,' and the reader is made to feel the relief of entering a shaded watercourse after crossing an open, sun-beaten plain. The same attentiveness to physical experience appears in his description of the bees that 'settle on one’s face and hands, and, in crawling about, get into the eyes and mouth, or up the nostrils.' The discomfort is specific, tactile, and unglamorous—a reminder that the naturalist's work is conducted in a body that sweats, itches, and tires.

Readers approaching The Naturalist on the River Amazons will find a work that rewards slow, attentive reading. Bates's prose is dense with particularities—the dimensions of a bee's gallery, the taste of honey, the feel of a forest path—and these details accumulate into a portrait of a place that is both scientifically informed and personally felt. The narrative does not offer a single dramatic arc; instead, it proceeds by accretion, moving from one observation to the next with the patient rhythm of a man who spent eleven years looking closely. To read it is to accompany Bates on his rambles, sharing in his discoveries and his frustrations alike.

That rainy afternoon, Bates’s meticulous ants and bees stayed with me long after the Amazon grew dim, their determined industry echoing strangely through the quiet. It made me wonder about other solitary travellers, charting their own vast, indifferent landscapes. I found myself reaching for Voyages in Search of the North-West Passage — Reading Notes, and the frozen silence there felt like a natural, colder companion to that humid, buzzing world.
