he night hauling quantities to the bank. The excitement each time a
fish 80 or 100 lb. in weight was hauled out of the water was
considerable. The wild yells and exquisite language whenever one of my
men was dragged into the water kept me awake the entire night.

We left that camp at 7.30 on July 17th, the minimum temperature having
been 66 deg. F. during the night. Heavy globular clouds covered the entire
sky. We were then in a region extraordinarily rich in rubber; quantities
of _Siphonia elastica_ trees were to be seen. It made one's heart bleed
to think that nobody was there to collect the riches of that wonderful
land.

The river flowed in short sections from north-west to north-north-east,
barring a long stretch of 4,000 m., when we came to a great basin 600 m.
wide, with two large islands in it; the eastern island--Orlando
Island--being 100 m. wide, the western--Elizabeth Chimay Island--220 m.
broad and not less than 500 m. long. South of both these islands were
islets of gravel 50 m. each in diameter.

Nine thousand five hundred metres below these islands an important
tributary, 8 m. wide, flowed into the Arinos from the right bank. It came
from the south-east. Close to the left bank, from which it had been
separated by the current, leaving a channel only 5 m. wide, another
island--Isabel Island--300 m. long was found.

Shortly afterwards we came to a big equilateral-triangular island--Armida
Island--fully 1 kil. 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 m. in a
direct line to 310 deg. b.m. Four large rocks in a cluster stood in the
centre of the stream at the north-north-westerly end of the island. Then
we had another stretch of 4,300 m., during which the river was squeezed
through a narrow neck, 100 m. wide, between low rocks. Immediately
afterwards we emerged into a bay 800 m. 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 m. wide. A deposit of gravel some 300 m.
long was exposed on the right side beyond the last island of the group.

Three kilometres farther 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 deg. F. in the sun,
