camp. He was most repulsive, with his enlarged features, 
especially the nose, of a ghastly, shiny, unwholesome, 
greenish white, and pitifully swollen feet and hands. 
The heat was not unbearable in that region — 89° 
Fahrenheit in the shade, 105° in the sun. There was a 
breeze blowing that day from the northeast, with a velocity 
of 200 metres a minute by anemometer. 
A good portion of the following day was wasted trying 
to recover fotir animals that had escaped. In order that 
they might graze properly it was necessary to let them 
loose. They sometimes strayed away long distances. 
Occasionally they hid in the shade of the motto (forest 
and shrub), and it was easy to miss them while looking 
for them. Luckily, two of my men, Alcides and a man

the animals, which was not at all difficult, as one had 
only to follow the marks of their hoofs to find where they 
had gone. 
We departed late in the afternoon through thick shrub, 
over marked undulations, in some spots quite steep. 
From the highest point that day (elevation 1,900 feet) 
we obtained an extensive view of flat tablelands in the 
distance to the east, with a low hill-range standing in 
front of them. It was scenery quite typical of Central 
Brazil, with no irregular, striking mountains; but every¬ 
where we had plenty to study in the effects of erosion on 
that great continent. 
I tried to make up for time lost by marching at night,

stray in all directions. I unfortunately had to hand over 
to my followers a few cartridges each, or else they would 
not come on. Every now and then that night they fired 
recklessly in the dark — much to the danger of beasts and 
men alike—thinking they had seen an Indian, or a
