"I'd rather you sang something cheerful," said the Kangaroo to herself, but out loud she said, "I find it really too beautiful, it is more than I can bear. Please go a little further off."

"Mo-poke! mo-poke!!" croaked the Nightjar, further and further in the distance, as it flew away.

"What a pity!" said the Kangaroo, as she returned to the cave, "the Possum made that unlucky joke of telling the Nightjar it has a touching voice, and can sing: everyone has to suffer for that joke of the Possum's. It doesn't matter to him, for he is awake all night, but it is too bad for his neighbours who want to sleep."

Just then there arose from the bush a shrill walling and shrieking that made Dot's heart stop with fear. It sounded terrible, as if something was wailing in great pain and suffering.

"Oh Kangaroo!" she cried, "what is the matter?" "That," said the Kangaroo, as she laid herself down to rest, "is the sound of the Curlew enjoying itself. They are sociable birds, and entertain a great deal. There is a party to-night, I suppose, and that is the expression of their enjoyment. I believe," she continued, with a suppressed yawn, "it's not so painful as it sounds. Willy Wagtail, who goes a great deal amongst Humans, says they do that sort of thing also; he has often heard them when he lived near the town."

Dot had never been in the town, but she was certain she had never heard anything like the Curlew's wailing in her home; and she wondered what Willy Wagtail meant, but she was too sleepy to ask: so she nestled a little closer to the Kangaroo, and with the shrieking of the Curlews, and the mournful note of the distant Mo-poke in her ears, she fell asleep again.

CHAPTER III.

When Dot awoke, she did so with a start of fear. Something in her sleep had seemed to tell her that she was in danger. At a first glance she saw that the Kangaroo had left her, and coiled upon her body was a young black Snake. Before Dot could move, she heard a voice from a tree, outside the cave, say, very softly, "Don't be afraid! Keep quite still, and you will not get hurt. Presently I'll kill that Snake. If I tried to do so now it might bite you; so let it sleep on."

She looked up in the direction of the tree, and saw a big Kookooburra perched on a bough, with all the creamy feathers of its breast fluffed out, and its crest very high. The Kookooburra is one of the jolliest birds in the bush, and is always cracking jokes, and laughing, but this one was keeping as quiet as he could. Still he could not be quite serious, and a smile played all round his huge beak. Dot could see that he was nearly bursting with suppressed laughter. He kept on saying, under his breath, "what a joke this is! What a capital joke! How they'll all laugh when I tell them." Just as if it was the funniest thing in the world to have a Snake coiled up on one's body—when the horrid thing might bite one with its poisonous fangs, at any moment!
