In the valleys, near water, burity palms were numerous.
Overhead the sky was always interesting. The days nearly invariably began with a clear, speckless sky, but, mind you, never of quite so deep a blue as the sky of Italy or Egypt. The sky of Central Brazil was always of a whitish cobalt blue. That morning—an exception to prove the rule—we had awakened to a thick mist around us, which enveloped and damped everything. No sooner did the sun rise than the mist was quickly dispelled. In the late morning, about 10 o'clock, clouds began to form high in the sky—not along the horizon, as is generally the case in most countries—and grew in intensity and size during the afternoon. Nearly every day at about sunset a peculiar flimsy, almost transparent, streak of mist stretched right across the sky from east to west, either in the shape of a curved line, or, as we had observed as recently as the day before, resembling with its side filaments a gigantic feather or the skeleton of a fish.
In the State of Goyaz, it may be remembered, we had a more beautiful and complete effect at sunset of many radiating lines, starting from the east and joining again to the west, but here we merely had one single streak dividing the sky in two. When the sun had long disappeared under the horizon, that streak high up in the sky was still lighted by its rays—becoming first golden, then red. The effect was quite weird.
My men went during the night on another fishing expedition, but with no luck—partly due to the infamy of our dogs. They used as bait for their large hooks toucinho, or pork fat, of which they had started out provided with a huge piece. They walked off a good distance from camp to find a suitable spot. Unfortunately, while they were there the dogs ate up all the toucinho and the result was that the men had to return disappointed. There was plenty of game, especially wild pig and veado (deer).
Alcides had a smattering of botany, which was a great danger to the company. He knew, he thought, the uses, medicinal or otherwise, of all plants, herbs and fruit, wild or not wild. This, in addition to the greediness of the men—who, although actually gorged with food, were always willing to devour anything else they found—led once or twice, as we shall see, to the poisoning of himself and his companions so dangerously as not only to cause terrible internal pains, but to bring them all actually to death's door.
I never got poisoned myself, as I generally took good care to watch the effects of those experiments upon my men first. Then also in my many years of exploration I had learnt only too well to beware of even the most seductive tropical plants and fruit. Notwithstanding all this, Alcides was really wonderful at turning out pleasant-tasting beverages from the stewed bark or leaves of various trees, and of these decoctions—in which additional quantities of sugar played an important part—my men and myself drank gallons upon gallons. Many of those drinks had powerful astringent qualities and had severe effects upon the bladder, but some were indeed quite good and innocuous.
During the night I observed a most perfect lunar halo, the circle, close to the moon, displaying a curious yellowish red outer fringe.
Since leaving the Araguaya we had been bothered a good deal nightly by the heavy dew, which absolutely soaked everything, made all our rifles and axes and iron implements rusty, and the tents and saddles and baggage considerably heavier for the animals to carry, owing to the moisture they had absorbed. In the early morning we began to get thick cold mist, and it was about that time that the minimum temperature was usually registered—58° Fahr. that particular night, May 19th. We were at quite a low elevation, merely 1,100 ft. When we started in the morning we found more sand and volcanic débris over ridges some 100 ft. or so above the level of the river. A torrent, 15 metres wide, flowing swiftly W.S.W. on a red lava bed, was crossed, the mules slipping terribly on the polished rock. More ashes and sand were found as we ascended to an elevation of 1,200 ft., from which height we discerned a much-terraced headland to the east and two streams meeting and flowing south where we eventually crossed them. One of those watercourses descended in cascades over laminated successive flows of lava, between which thin layers of white crystallization could be seen.
Slightly higher, at 1,250 ft., we sank again in yellow and grey ashes.
Across campos we reached another foaming torrent, flowing as usual over a lava bed, but this time in a north-westerly instead of in a southerly direction. That day we met with many watercourses. Having risen to 1,450 ft., we soon after found another streamlet (elev. 1,230 ft.). Again a red lava-flow was exposed in its bed and showed heavy upper deposits of grey ashes, with above them a thick layer of yellow-ochre sand (1,300 ft.).
