d in the back part of
the cage, with an expression upon his countenance in which the lofty
pride and majesty of his character, and the patience and submissiveness
which pertained to his situation, were combined.

"Poor fellow!" said Rollo; "if I had you and your cage in Africa, where
you belong, I would open the door and let you go."

Just at this moment the attention of both Rollo and Carlos was suddenly
arrested by a most unearthly sound at a little distance from them, which
seemed to be intermediate between a scream and a roar. It was so loud,
too, as to be truly terrific.

"What's that?" said Rollo, suddenly, in English.

"Ah, what a dreadful bray that is!" said Carlos, in Spanish.

"Would you go out there and see what it is?" said Rollo.

"Hark! Let's go there and see what it is," said Carlos.

So the boys started together to go in the direction of the sound.

It is impossible, however, for a stranger in the Garden of Plants to be

of them, which was the residence of a pair of beautiful lamas, and told
Carlos that he meant to ask his uncle George to take particular notice
how it was made, and so make one for him for a play-house when he got
home.

"And I wonder," said he, "where my uncle George and Jennie are. I don't
see how we are ever to find them. I did not know that this garden was so
large and so full of trees and bushes."

"Look there!" said Carlos, pointing through an opening in the shrubbery
along the winding walk. "What are they doing there?"

Rollo, understanding the gesture, though not the words, turned in the
