There was something languorous and velvety about the heat. A stifling fragrance came from the inflorescences of Vallieria mirifica, mother-of-pearl in color and resembling clusters of soap bubbles, that arched across the narrow, dry streambed along which we proceeded. The branches of porphyroferous trees intertwined with those of the black-leafed limia to form a tunnel, penetrated here and there by a ray of hazy light. Above, in the thick mass of vegetation, among brilliant pendulous racemes and strange dark tangles of some kind, hoary monkeys snapped and chattered, while a cometlike bird flashed like Bengal light, crying out in its small, shrill voice. I kept telling myself that my head was heavy from the long march, the heat, the medley of colors, and the forest din, but secretly I knew that I was ill. I surmised it to be the local fever. I had resolved, however, to conceal my condition from Gregson, and had assumed a cheerful, even merry air, when disaster struck.

‘It’s my fault,’ said Gregson. ‘I should never have got involved with him.’

We were now alone. Cook and all eight of the natives, with tent, folding boat, supplies, and collections, had deserted us and vanished noiselessly while we busied ourselves in the thick bush, chasing fascinating insects. I think we tried to catch up with the fugitives – I do not recall clearly, but, in any case, we failed. We had to decide whether to return to Zonraki or continue our projected itinerary, across as yet unknown country, toward the Gurano Hills. The unknown won out. We moved on. I was already shivering all over and deafened by quinine, but still went on collecting nameless plants, while Gregson, though fully realizing the danger of our situation, continued catching butterflies and diptera as avidly as ever.

We had scarcely walked half a mile when suddenly Cook overtook us. His shirt was torn – apparently by himself, deliberately – and he was panting and gasping. Without a word Gregson drew his revolver and prepared to shoot the scoundrel, but he threw himself at Gregson’s feet and, shielding his head with both arms, began to swear that the natives had led him away by force and had wanted to eat him (which was a lie, for the Badonians are not cannibals). I suspect that he had easily incited them, stupid and timorous as they were, to abandon the dubious journey, but had not taken into account that he could not keep up with their powerful stride and, having fallen hopelessly behind, had returned to us. Because of him invaluable collections were lost. He had to die. But Gregson put away the revolver and we moved on, with Cook wheezing and stumbling behind.
