The riding-saddles, too, were almost as absurd as the pack-saddles, constructed as they were of innumerable and useless pieces of wood, iron and leather. The stirrups were gaudy, and consisted of a regular shoe of silver or other metal, into which you inserted the greater part of your foot, or else of a much ornamented circular ring. The head-piece and bit were also extremely heavy, clumsy, and highly decorated, for everything must be made for show if it had to be used in Brazil.

It was not possible to associate in any way or be friendly with my men. They were unpleasant beyond all conception. One could not say a word—no matter how kind—without the prospect of a long argument or a row. It was quite beyond them to be civil, and, like all ignorant people, they always imagined that they could teach others everything—including good manners! They were ridiculously courteous to one another—a muleteer talking to another always addressing him as "Sir," and referring to his comrades as his "colleagues."

We travelled that day nearly altogether over finely powdered reddish earth of volcanic origin. I had so far not met with a single fossil, not a shell, not a petrified bone of any animal, nor, indeed, impressions on rock of leaves, twigs or other parts of plants. The farther one went on, the more one had proof that that portion at least of the American continent had never been submerged in its entirety.

Some rocks displayed on the surface peculiar perforations such as would be produced by incessant water dripping over them, but these were caused, I think, merely by water falling over them while they were in a molten state; other rocks were thoroughly polished on the surface, as if sand or other gritty substance had flowed with great force over them, mixed with water—perhaps during a period of volcanic activity and torrential rains.

Geological research was somewhat difficult for a passing traveller in that region, for everything was smothered in vegetation. Only here and there in the cuts of rivers was I able to judge a little better of the actual formation of the land.

We camped on the stream Agua Limpa, which duly deserved its name of "clear water" (elev. 1,470 ft.). It flowed south. On May 4th, going through forest again over a hill (elev. 1,650 ft.), we obtained a glorious view of the immense expanse to the west and to the south-west—a great stretch of greenish, long sweeping lines with a plateau in the background. A somewhat taller hill rose at one end of it. We then descended to another deliciously clear river, which deserved as well as the previous one the name of Agua Limpa (elev. 1,450 ft.), but this one flowed north into the Rio Claro. The land was fine, sparsely wooded all the time, absolutely flat, but getting slightly undulating beyond that stream. It seemed wonderful land for agricultural purposes.

After passing the Indain River, the Bom Successo, and another stream, all three flowing south, we swerved more to the north-west, rising up on an elevated spot, from which we obtained another glorious panorama, a high Serra to the west, another in the distance to the east, the two extending almost parallel towards the south, where the gap in the horizon line between these ranges was filled by a very distant range showing a conical peak, and to the west of this another in the shape of a dome. It was the grandeur of these panoramas that impressed one most, rather than their monotonous beauty.

All the outlines of the scenery of Central Brazil had, so to speak, been worn smooth by the erosive action of water and wind, so that no fantastically shaped mountains had yet been encountered, no landscape which some great commotion had rendered strangely picturesque. There, only the steady work of uncountable ages showed itself in a most impressive way to those who understood. From a striking pictorial point of view very little remained in one's mind of those wonderful scenes after one had turned one's head away, except, perhaps, their immensity and the deep green tones—the two salient points of the scenery.

When we had descended from the pass (elev. 1,650 ft.) we came to the Rio Tres de Majo, where a hamlet of three sheds was found. Twenty-eight kilometres from our last camp we arrived at the Rio Rancheria, where stood a miserable farm. Both those streams, at an elevation of 1,300 ft., flowed into the Rio Claro to the north.

We had the misfortune of halting near the farmhouse, and suffered tortures from the millions of mosquitoes, gnats, carrapatos and carrapatinhos which made that night almost unbearable. I invariably found that carrapatos and carrapatinhos were more plentiful where living people or animals were to be found. Near those dirty farmhouses we were simply swarming all over with them. My poor animals, owing to the long marches we had been making, and the terrible pack-saddles, had sore backs and loins, sore chests. Yet we could not stop, and the poor things must stand the pain and strain.
