HOW WILD ANIMALS ARE CAUGHT 97 
enormous swamps, hundreds of square miles in extent, and 
my travellers were laid low with very severe attacks of fever. 
Moreover, that region is infested by bloodthirsty savages who 
repeatedly attacked the expedition and hindered its advance. 
Notwithstanding this failure, I have not relinquished the hope 
of being able to present science with indisputable evidence of 
the existence of the monster. And perhaps if I succeed in 
this enterprise naturalists all the world over will be roused to 
hunt vigorously for other unknown animals; for if this pro- 
digious dinosaur, which is supposed to have been extinct for 
hundreds of thousands of years, be still in existence, what 
other wonders may not be brought to light?
