GEORGE REX ISLAND 
halting-place on a natural terrace of volcanic rock some 
20 feet above the river, with a dome of rock in the centre. 
I met signs of Indians close to the river. Evidently a 
tribe had once halted there, but apparently many years 
before our arrival. I discovered their fireplaces, several 
carved pieces of wood, and some fragments of rudi¬ 
mentary pottery in the neighbourhood of this picturesque 
spot. In exploring round the place I also found some 
almost entirely obliterated indications of several ancient 
trails, which had been made by the Indians in the forest. 
Looking toward bearings magnetic 340°, and also in 
the opposite direction to the south, most gorgeous river 
scenes were before us. This was by far the most 
beautiful spot I had come across on the river so far. I 
therefore named the huge island on which I stood George 
Rex Island. I gave Alcides orders to carve the name 
on a tree, but as he was an anarchist he refused to do 
it, excusing himself by saying that he had injured his 
hand. 
At that camp we caught over 400 pounds of fish in 
less than half an hour, three jahus among the number, 
each weighing over forty pounds. Then we also captured 
two cachorra , or dog fish, which possessed vicious-looking 
molars of great length, not unlike those of a big dog. 
Each of these fish weighed over thirty pounds. Then we 
got eight trahiras, some twenty pounds each in weight. 
With the little salt which remained we preserved some of 
the fish, as we were now getting very short of food. How¬ 
ever, we had excellent meals most of the time on the river, 
frying the fish with fat which we extracted from the fish 
itself. 
During the night of July twenty-sixth we had a mini¬ 
mum temperature of 55° Fahrenheit, but as we had had 
plenty to eat the previous evening, in fact, too much, we 
did not feel the cold quite so severely. 
Ariranhas in large families were plentiful near that
