An unnamed man vacationing at his farm near Campo Grande, Brazil, reported an encounter on December 15, 1954, while fishing near a river. He said his dog began howling and an unusual object appeared a few hundred feet away. Fuller accounts describe a small sphere revolving around a larger one, which remained approximately two metres above the ground and had three ball-like supports.
The witness reportedly used a gun's telescopic sight to observe three small, agile, humanlike occupants. One carried a luminous basket; another used a tube with a cone-shaped end. Their activity was interpreted as collecting material from the riverbank, drawing it into the tube and transferring it to the basket. They then returned to the object, which departed rapidly. Square holes were subsequently reported at the site.
The case reached the literature through Brazilian investigators and the Lorenzens, with references to Colonel Adil de Oliveira and scientist Olavo Fontes. The inherited chemical abbreviations concern material associated with the story; they should not be read as a verified extraterrestrial composition. The accessible summaries do not provide a controlled chain of custody or an original laboratory report. The observer's anonymity and the retrospective publication trail limit independent checking of the sampling scene and ground marks.
Retells the anonymous fisherman’s account of occupants collecting material. The source trail does not supply an original laboratory report or controlled custody for alleged samples; chemical abbreviations are not verified extraterrestrial composition. Anonymous retrospective account. Illustrated narration supplies no recovered laboratory report or controlled material chain of custody; sampling and holes remain attributed claims, not established extraterrestrial evidence.
