A DOUBLE-TOWERED MOUNTAIN 
death by the piurn or lambe-olhos (eye-lickers), as the 
Brazilians call them, which followed us all day in swarms 
around our heads and hands, entering our mouths, noses, 
eyes, and ears. Only for a few moments, when there blew 
a gust of wind, were we freed from this pest, but they 
soon returned to their attack with renewed vigour. 
We rose again to an altitude of 2,380 feet on another 
great dome of red lava, which had flowed northwards, as 
could be plainly seen as we ascended on its rounded back. 
Upon it were quantities of crystals and yellow lava pellets 
and pebbles and carbonated rock, resting on whitish and 
grey ashes. On the summit, where, fully exposed, numer¬ 
ous perforations, cracks, and striations were visible in the 
flow, we were able to observe plainly how the lava in a 
liquid state had flowed and quickly cooled, while other 
strata of liquid lava flowed over it, one overlapping 
another like the scales of a fish, and forming so many oval 
or ovoid bosses with channels between. 
From that high point we had a perfectly level sky¬ 
line all around us, except for the Paredao Grande and 
the Paredaozinho, then to the east-northeast of us. 
At an elevation of 2,520 feet we perceived that day 
to the east-southeast a double-towered, massive, rocky 
mountain of a brilliant red colour, reminding one of 
the shape of an Egyptian temple, and a lower hill 
range in undulations behind it to the south, projecting 
at its sides. 
We were marching on the northern edge of deep and 
extensive depressions to the south and southeast of us. 
Domed undulations in progressive steps from north to 
south were noticeable in the southern portion of the land¬ 
scape, and from south to north in the northern and 
much-wooded zone. 
When we were at an elevation of 2,550 feet we had 
still red and yellow sand and ashes with stunted and sparse 
vegetation. Upon descending, we skirted the southern
