ACROSS UNKNOWN SOUTH AMERICA 
When we started in the afternoon we continued to 
travel in a direction of 330° bearings magnetic, and came 
to a large basin, easily identifiable by subsequent travellers 
by three extensive domes of granite on the right side, two 
of them actually on the bank of the stream at the entrance 
of the basin. Where an elongated island, 3,000 metres 
long, Oriana Island, beside which we had travelled, ended 
on our left, we saw another island that continued half-way 
down the basin, here some 2,000 metres wide. The second 
island, Diana Island, was fully 8,000 metres in length. 
In the centre of this great basin was a triangular island, 
Pomona Island, 4,000 metres long and with a base of 
1,500 metres. A tributary was visible on the right bank, 
just opposite a great dome of granite with an appendix 
of sand and gravel which stood in the middle of the 
channel. After we had travelled for 2,500 metres, a basin 
some 1,400 metres wide opened again, with a small island, 
400 metres long, in the centre, Maude Adams Island. 
This charming islet had a picturesque headland of rock 
on the south side, and a long spur, also of rock, 
to the north. We made our camp here. The river was 
really marvellously beautiful at this point, the vegeta¬ 
tion all round being vigorous and healthy, with a great 
wealth of rubber trees, while the huge volcanic rocks 
strewn about added much to the picturesqueness of the 
scene. 
It was warm during the night (minimum temperature 
63° Fahrenheit), and we were treated to a most torment¬ 
ing concert of mosquitoes. They swarmed positively in 
millions around us. With my bed and bedding which I 
had lost in the rapids I had unfortunately also lost my 
mosquito net, and I now was suffering greatly from the 
stings of all the troublesome insects. My bones were 
aching all over from sleeping on the uneven packing-cases 
placed in a row, which now formed my bed. It took two 
much time and trouble to unfasten the straps and buckles
