ACROSS UNKNOWN SOUTH AMERICA 
two large islands in it; the eastern island, Orlando Island, 
being 100 metres wide, the western, Elizabeth Chimay 
Island, 220 metres broad and not less than 500 metres 
long. South of both these islands were islets of gravel 
50 metres each in diameter. 
Nine thousand five hundred metres below these islands 
an important tributary, eight metres wide, flowed into the 
Arinos from the right bank. It came from the southeast. 
Close to the left bank, from which it had been separated 
by the current, leaving a channel only five metres wide, 
another island, Isabel Island, 300 metres long, was found. 
Shortly afterward we came to a big equilateral- 
triangular island, Armida Island, fully one kilometre a 
side. Albert Island, next to it, was of a narrow elongated 
shape. 
From the beginning of Armida Island the river flowed 
for 4,000 metres in a direct line to 310° bearings magnetic. 
Four large rocks in a cluster stood in the centre of the 
stream at the north-northwesterly end of the island. Then 
we had another stretch of 4,300 metres, during which the 
river was squeezed through a narrow neck, 100 metres 
wide, between low rocks. Immediately afterwards we 
emerged into a bay 800 metres broad, with three islets 
on one side of it. They were rather dry and somewhat 
mean-looking. I called them Faith, Hope, and Charity 
Islands. 
After that the river was 800 metres wide. A deposit 
of gravel some 300 metres long was exposed on the right 
side beyond the last island of the group. 
Three kilometres further we halted for an hour or so, 
just time enough for me to take the latitude and longitude 
and for our lunch to be cooked. The usual torture had 
to be endured from the innumerable insects. The heat 
was also terrible —107° Fahrenheit in the sun, 93° in 
the shade. Latitude 11° 23'.9 south; longitude 57° 39' 
west.
