We descended to 1,300 ft. (above the sea level) through thin forest, in a valley where bamboo was abundant as well as gamelleira trees with their winged roots of great size. The gamelleira was somewhat larger than the garappa or garabu. We found in that valley a beautiful grove of akurí palms, the palms being 10 to 15 ft. high. In going through—cutting our way with falcons—long heavy-bladed knives specially made for cutting through forests—we were much worried by spiders' webs of great size, from which we had trouble in extricating our heads and hands as we went along. There were thousands of those webs at the entrance of the forest, and we dragged them all along on our passage. With their viscous properties they clung to us, and we could only shake them off with difficulty.
Most interesting of all was the cepa d'agua—a powerful liana, four inches in diameter, festooned from the highest branches of trees, and which when cut ejected most delicious cool water. Then there was a tree called by the Brazilians "mulher pobre," or "poor woman's tree"—do you know why?—because from its juice it was possible to make soap, which saved the expense of buying it. There was a roundabout way of reasoning for you.
Eighteen kilometres from our last camp we came to a rapid streamlet of the most limpid water, the Rio Mazagan (elev. 1,300 ft. above the sea level), four metres wide and four inches deep. When we drank it it nearly made us ill, so foul was its taste of sulphur and lead. The treacherous stream flowed into the Cuyabá River.
There were many tamburi trees of great proportions, handsome trees with clean, healthy white bark and minute leaves—at the summit of the tree only. In the forest, although the taller trees were generally far apart, none of them had branches or leaves lower than 30 to 40 ft. from the ground. The angico or angicu (Piptadenia rigida Benth.), which was quite plentiful, was also a good-looking tree of appreciable height and circumference.
Upon emerging from the beautiful forest, quite clear underneath with only a few ferns, we crossed great campos—"campina grande," as my Brazilians called them. Skirting the forest in a northerly direction, we went over a low hill range with delightful clear campos and patches of forest. We crossed another streamlet of foul-tasting water—with a strong flavour apparently of lead.
In the great undulating valley we left behind—as we now altered our course slightly to the north-west—was prominent a double-humped hill which rose higher than any other except in the north-west portion of the landscape. There a high chain of hills could be seen.
When we crossed over the second ridge (elev. 1,400 ft.), strewn with yellow lava pellets, at the end of extensive campos we obtained an imposing view to the north. An elevated flat-topped table-land of great magnitude rose in front of us—a perfectly straight line against the sky, but terminating abruptly with three gigantic steps, with a subsidiary one upon the second step, at its western end. This plateau stood out, a brilliant mass of cobalt blue with great projecting spurs, like a half-section of a cone surmounted by a semi-cylindrical tower along the southern wall of the plateau. Then a strange hill mass of four distinct composite domed heights with minor peaks stood between the plateau and us—and extended, like most of the other ranges, from south-east to north-west.
