"But I've never seen them," he said.

"Nor has Miss Chase ever seen a dingo," said Bob calmly.—"It is the wild dog of the Bush, Miss Chase. They come prowling round the house at night, looking for food."

The howling grew worse and worse. Bob quietly sauntered out on to the veranda. There were a few shots, and the noise changed to yelps as the dingoes scurried in terror down the hill.

"Don't be worried if you hear them in the distance most of the night," said Mrs. Orban. "I am afraid it will take you some time to get used to our noisy hours of darkness."

When Miss Chase tried to settle down to sleep she remembered these words, and it seemed superfluous to her that she should have been wished "good-night" by every one. A good night was impossible. The dingoes howled persistently in the woods below, and quite close there was the incessant "croak-croak-croak-croak" of tree-frogs, together with many other inexplicable and weird noises.

Nesta slept placidly through it all; but not till there came a lull just an hour or so before dawn did the weary stranger drop into oblivion.

It did not seem to her she had been asleep five minutes, and there was only the faintest glimmer of light in her room, when she was awakened by something new. Just under her window there was a strident laugh.

"Ha-ha-ha!" Then another, "Ha-ha-ha!"

Miss Chase listened in bewilderment.

"What extraordinary people," she thought, glancing enviously at the undisturbed Nesta. "Who on earth can be out at this time?"
