A BRIGHTLY COLOURED CLIFF 
hills some 300 feet high then appeared before us, extend¬ 
ing from north-northwest to south-southeast. 
We went over a stony place which obstructed almost 
the entire river, except a narrow channel close to the 
banks. That was followed by rapids. Some 2 kilometres 
300 metres farther, a hill range to the north switched 
the stream sharply from north to northwest, which 
direction it kept with a mere deviation of 20° for 6,500 
metres. 
The stream was then 100 metres wide nearly all along, 
and of amazing beauty. Yet another stony place dis¬ 
turbed the placidity of the transparent crystal-like water. 
At the end of that wonderful stretch of river came another 
great vertical wall, on the left side — of most brilliant 
colouring, a stratum of vivid red 60 feet deep with thin 
bright horizontal yellow streaks, and an upper stratum 
18 feet thick of a similar dazzling yellow. The northern 
portion of the cliff differed in colouring, and had a brown 
lower stratum 30 feet thick, followed upwards by a yellow 
stratum 2 feet thick, and a red stratum, a most brilliant 
vermilion, 15 feet thick. Above was a pink layer 15 feet 
thick and a summit deposit of brown earth 45 feet deep. 
There again the river was shifted by that obstacle from 
bearings magnetic 290° to due north. A charming island 
— which I baptized Bridget Island —700 metres long 
and 100 metres wide, absolutely smothered in vegetation, 
was found there. It had an extensive spur of yellow sand 
and gravel. The right bank was sparsely wooded with 
open country behind. Two channels were found, one 
flowing northwest, 40 metres wide, the other northeast, 30 
metres broad. We followed the latter, where the rapids 
seemed less fearsome than in the broader channel. 
At the end of Bridget Island another island, 500 
metres long, was found, which we called Lucky Island. 
This second island was 200 metres down stream from the 
first, and was situated at the junction of the river dos
