A BEAUTIFUL REGION 
in the day we reluctantly went on in a northwesterly 
direction, first for four kilometres, then northeast for five 
kilometres, passing through a large basin 300 metres wide, 
containing two islets, then passing charming sand beaches, 
and farther on another tributary, eight metres wide, on 
the left of us, also with deliciously clear water. When 
we proceeded on our journey after lunch we found big 
rocks more frequent in the stream, and went over a field 
of great boulders just under the surface of the water that 
stretched half-way across the shallow river. 
Eight kilometres from our halting-place we came to 
an extensive stony place with a strong rapid. One kilo¬ 
metre beyond, a small tributary flowed into the Arinos 
from the left side. On the left side we had a red and 
brilliant yellow bank seventy feet high, part of a small 
range of hills which turned the river from north-northwest 
to north-northeast. Another small tributary two metres 
wide was seen on the left side. Then, four kilometres 
farther on, another tributary, also two metres wide, and 
also on the left side, came from the southwest. Three 
thousand six hundred metres beyond this, we entered a 
basin 320 metres wide with an island 150 metres long, 
including its gravel spit. Three more islands were seen 
a little way beyond, Meraud, Tanis, and Loel Islands, 
Meraud being the largest. Another island was on the 
left of the river, leaving a passage fifty metres wide on its 
west side. The group of islands was of alluvial formation 
with deposits of gravel below. 
The river in that region was too beautiful for words. 
The foliage of the thick heavy forest on both sides was 
densely green, the banks most tidy, and running in an 
almost straight line for 10,000 metres. During all that 
distance the stream was 300 metres wide, and its speckless 
water reflected with marvellous definition each leaf and 
branch against the background of deep green. Neat 
gravel banks occurred frequently in the shallow water.
