THE SUNSETS IN BRAZIL

blended into a more indefinite mass. The radiations did 
not begin from the vanishing sun on the horizon, nor at 
the point diametrically opposite on the east, but began 
to appear only one tenth up the entire circle of the sky, 
both west and east. 
Almost globular cloudlets, with the lower section cut 
off in a horizontal plane — quite typical, as we have seen, 
of the cloud formation on that Central Brazil plateau — 
crowded the sky, quite low to the north, and also a great 
many small, ball-like clouds, which showed with some 
brilliancy against the blue sky. 
The sunsets in Central Brazil were to me always a 
source of intense joy, interest, and admiration. With 
certain characteristics which repeated themselves fre¬ 
quently, they always displayed wonderful effects of light 
and a most peculiar formation of clouds. 
Before reaching camp we passed another oval cuvette 
with a longitudinal row of trees, so green and tidy as to 
be just like a portion of a well-kept English park (eleva¬ 
tion 2,350 feet). Another bit of wonderful scenery, with 
immense, prismatic, rocky mountains — really more like 
dykes — appeared in the distance; and also a vertical, 
walled mountain in the foreground.
