South of the ravine, in the plain that stretches to the lake shore, another less hot and less gassy sulphurous spring gushes out. The thermometer reached only 42°C. The water collects in a basin surrounded by large trees. The unhappy slaves throw themselves in this pool at sunset, covered in dust after working in the indigo and sugar-cane fields. Despite the water being 52°C to 14°C warmer than the air the negroes call it refreshing. In the torrid zone this word is used for anything that restores your strength, calms nerves or produces a feeling of well-being. We also experienced the salutary effects of this bath. We had our hammocks slung in the trees shading this pond and spent a whole day in this place so rich in plants. Near this bãno de Mariara we found the volador or gyrocarpus. The winged fruits of this tree seem like flying beings when they separate from the stem. On shaking the branches of the volador, we saw the air filled with its fruits, all falling together. We sent some fruit to Europe, and they germinated in Berlin, Paris and Malmaison. The numerous plants of the volador, now seen in hothouses, owe their origin to the only tree of its kind found near Mariara.
