where. Its summit, with an undulating sky-line, lay to 
the west of it, no doubt formed by erupted matter. Other 
great vertical furrows were noticeable not far from the 
crater and to the west of it. 
The scenery was getting stranger and stranger every 
day. We began to notice solitary domes and cones in the 
landscape. That day, in fact, beyond the great campos, 
we had before us a curious, little, well-rounded dome, 
standing up by itself upon an absolutely flat surface, at a 
considerable distance from the flat tableland which stood 
on one side, and of which formerly it evidently made part. 
Higher mountains, somewhat nearer to us, were on 
the southwest. 
We had reached the River Corgo Fundo (elevation 
1,250 feet), along the banks of which the laminse of red- 
baked rock could be observed with thin white layers 
between. Above was a lovely green pasture with a tuft of 
deep green trees, which looked exactly like a bit of a 
well-kept English park. We mounted up again to 1,430 
feet, then went down another descent into a large plain 
with campos, upon which grew merely a few stunted 
trees. We were still travelling over deep deposits of 
sand. 
The range to the north of us extended, to be accurate, 
from northeast to southwest, and at its southwesterly 
end possessed a dome not dissimilar to the one already 
described on our previous day’s march. This one was 
perhaps more rounded and not quite so tall. It rose above 
the plateau in two well-defined terraces, especially on the 
northeast side, but was slightly worn and smoothed to 
the southwest. On the terminal mound, clearly separated 
from the range by erosion, seven distinct terraces could 
be counted, with some less defined, intermediate ones. 
In the bed of another stream flowing south — it was 
impossible to ascertain the names of these streamlets, for 
there was no one to tell, and none were marked on existing
