This zone is the home of the gigantic elephant and giraffe; of the lion
and the tiger, the most powerful of all the beasts of prey; and of the
gorilla, chimpanzee, and ourang-outang, of all animals most resembling
men.
Here, also, are the ostrich, the largest and most powerful of birds; the
condor, surpassing in size all other birds of flight; and the
humming-birds of South America, the smallest of the feathered tribes,
unsurpassed in brilliancy of coloring, rapidity of motion, and grace of
form.
In the same zone are those enormous reptiles, the crocodile and the
boa-constrictor, with the hooded snakes and other serpents of most
deadly venom; and insects of all sizes in indescribable profusion.
