d undoubtedly the poor beast eventually must have died of
starvation, as there was no food whatever to be obtained in the forest on
the island.

The dogs were quite amusing to watch while in the canoe, their terror
when we shot rapids being quite manifest. They were an additional source
of danger to us, for once or twice while shooting rapids strewn with
rocks they would jump out of the canoe on to the rocks as we were shaving
past them, and we lost much time on several occasions in order to rescue
them. In going through the forest the poor animals had suffered much from
the attacks of ants and all kinds of insects, many parasites having got
inside their ears and where the skin was softer under their legs, causing
terrible sores.

They never got fond of anybody, no matter how well they were treated. In
fact, unlike all other dogs of any other country, they never seemed even
to recognize any of us. Alcides had become the owner of the abandoned dog
in a peculiar way at the beginning of our journey, when travelling with
my caravan of mules. The dog was going along with a man travelling in the
opposite direction to ours. Alcides, who at the time was eating some
bread, whistled to the dog, and from that moment the animal left his
master and came along with us.

Perhaps Brazilian dogs do not give affection because they never receive
any. They were so timid that when you lifted your hand to caress them
they would dash away yelling, with their tails between their legs, as if
you had been about to strike them. I tried time after time to make
friends with them--and I am generally quick at making friends with
animals--but I gave up in despair the hope of gaining the slightest
affection from those dogs.

When we came to the end of the island we found another great barrier of
foliated rock extending from east to west, 500 m. across. The basin
showed, moreover, three sets of giant rocks on the left side. In the
north-easterly part where the river narrowed again there stood a range of
hills 300 ft. high, extending from west to east, and parallel to the
rocky barrier across the basin. A streamlet 3 m. wide coming from the
south-west entered the Arinos from the left bank. The hill range which
stood along the right bank of the river showed a rocky formation of a
greyish colour right up to its summit, and was, in fact, a mere great
rocky barrier with only a few trees growing in interstices which had been
filled with earth and sand. Th
