m I was accompanied by Captain Vicente
Montes, of the Argentine Navy, an accomplished officer of scientific
attainments. He had at one time been engaged on a survey of the
boundary between the Argentine and Parana and Brazil. They had a
quantity of dried beef in camp. On several occasions a jaguar came
into camp after this dried beef. Finally they succeeded in protecting
it so that he could not reach it. The result, however, was disastrous.
On the next occasion that he visited camp, at midnight, he seized a
man. Everybody was asleep at the time, and the jaguar came in so
noiselessly as to elude the vigilance of the dogs. As he seized the
man, the latter gave one yell, but the next moment was killed, the
jaguar driving his fangs through the man's skull into the brain. There
was a scene of uproar and confusion, and the jaguar was forced to drop
his prey and flee into the woods. Next morning they followed him with
the dogs, and finally killed him. He was a large male, in first-class
condition. The only features of note about these two incidents was
that in each case the man-eater was a powerful animal in the prime of
life; whereas it frequently happens that the jaguars that turn man-
eaters are old animals, and have become too inactive or too feeble to
catch their ordinary prey.

During the two months before starting from Asuncion, in Paraguay, for
our journey into the interior, I was kept so busy that I had scant
time to think of natural history. But in a strange land a man who
cares for wild birds and wild beasts always sees and hears something
that is new to him and interests him. In the dense tropical woods near
Rio Janeiro I heard in late October--springtime, near the southern
tropic--the songs of many birds that I could not identify. But the
most beautiful music was from a shy woodland thrush, sombre-colored,
which lived near the ground in the thick timber, but sang high among
the branches. At a great distance we could hear the ringing, musical,
bell-like note, long-drawn and of piercing sweetness, which occurs at
intervals in the song; at first I thought this was the song, but when
it was possible to approach the singer I found that these far-sounding
notes were scattered through a continuous song of great melody. I
never listened to one that impressed me more. In different places in
Argentina I heard and saw the Argentine mocking-bird, which is not
very unlike our own, and is also a delightful and remarkable singer
