ng at the groups of
visitors that were gazing upon him from without the paling; while the
third was amusing himself by galloping about the yard, with a sort of
rolling motion that it was most astonishing to see.

Rollo and Carlos advanced among these scenes, drawn from one to the
other by the new objects which every where presented themselves to
view, and uttering to each other continual exclamations of astonishment.
In fact, they talked incessantly to one another as they walked on,
pointing out, each to the other, whatever attracted their attention, and
making all sorts of comments upon what they saw.

Presently a low, bellowing sound was heard among the trees at a little
distance.

"Hark!" said Rollo, in English, putting his hand upon Carlos's shoulder.

to and fro restlessly in their narrow prisons; others were lying down;
and others still were crouched in a corner of their cage, where they
remained motionless, gazing with a sullen air upon the visitors who

Rollo and Carlos walked back and forth in front of these cages several
times, looking at the animals. They admired the beauty and grace of the
tigers and leopards, and the majestic dignity of the lions. There were a
lion and a lioness together in one cage. The lioness was walking
restlessly to and fro; while the lion sat crouche
