The most attractive little creatures in the American forests are the
capucins, the best-known of which is the Sai capucinus. Their tails,
though covered with hair, are prehensile. They are active and lively in
the extreme, leaping about from bough to bough, and eagerly watching all
that goes forward in the world below. There are several species of
similar habits, their quaint ways and general intelligence making them
all great favourites when tamed. They live chiefly on vegetable food,
but they devour insects and eggs, and do not object to a bird when they
can manage to catch one.
