"The quagga is not a native of Australia, Gerald," replied Mr. Mayburn; "nor does the country, happily, produce any of the large and fierce quadrupeds. We must not dare to think of any vehicle for travelling; yet many hundred miles separate us from the useful animals of our dear friends the Deverells; and my heart fails me when I reflect on the improbability of our ever reaching them."

Margaret sighed as she said, "And I too, dear papa, cannot help many idle wishes that we were come to open plains, and more direct paths. These lovely wilds of Nature, forests and mountains, are very charming; but they seem too romantic and unreal to be satisfactory. If we were to keep a journal, and publish it hereafter, we should, I fear, be ridiculed for inventing fairy tales."

"In truth, Margaret," answered her father, "fairy tales were not originally mere inventions of the imagination. They were the offspring of the experience of observing travellers over lovely untrodden wilds like these. And what are the miraculous transformations they describe but such as might really happen—the ingenious contrivances of man when destitute of all the resources of civilized life? Has not Jack transformed a flint-stone into an axe? and have we not cups and plates which were once the abodes of the shell-fish? Difficulties originate miraculous efforts, and man is indebted to the good fairies, Necessity and Ingenuity, for many of his comforts."

"Very true, dear papa," said Arthur; "and the fairy Necessity now calls on us peremptorily to escape from these forests, where I have twice during this day heard the coo-ee of the natives, though at a considerable distance before us. I have been for some time anxiously examining the south side of the gorge for any outlet which may enable us to turn away from their haunts."

They had been making their way for some hours along the southern extremity of the forest, still hemmed in by the high rocks, when Gerald, creeping into a narrow cleft, declared that he had found a tunnel, and called on Hugh to assist him in exploring it. Fearful that they should bewilder themselves in the recesses of the mountains, Arthur proposed that all the party should enter the opening, which was a cavern of great height and space, where they might remain till he and his brothers penetrated further into the rocks. They lighted some dry branches for torches, and set out, satisfied that the rest would be in safety in this secure retreat.

The boys found this tunnel descend gradually: sometimes it was narrow and low, sometimes wide and encumbered with fallen fragments of rock; still, it was airy, and they were able to pass on, till they concluded they must have walked half a mile. They were then so desponding that they thought of turning back, but at length a glimmering of light satisfied them that there must be another outlet, and they took courage to proceed, till they reached a matted thicket of brushwood through which they forced their way, and then had the pleasure of seeing the sky above their heads, though they were still in a very narrow gully. It seemed to be the dry bed of a rivulet, choked up with stones and torn-up bushes. Before them rose another line of bush-covered mountains, but not so lofty or precipitous as those they had left behind.

"Is it worth while," said Hugh, "to drag the whole party through that gloomy subterranean passage, to bring them into this glen, which seems perfectly barren and lifeless? I am of opinion that we were better in our old forest."

"Wait for my decision," said Gerald, springing up the side of the opposite mountains, regardless of the rending of his light blouse, and his scratched hands; and before long he stood on the summit.

"This will do for us capitally," he cried out. "Wide plains below, but an awkward step down to them. Jack will have to cut a staircase again."

This account of the country satisfied Arthur, and they hastened back at once to relieve the anxiety of their friends, whom they found in a state of great alarm. The cries of the savages had gradually approached so near to them, that Margaret induced Wilkins and Jack to close the opening by which they had entered with a large piece of rock. Then they had heard voices close to the rocks, and Baldabella, who was now able to speak many English words, said—"Many bad black fellows! much bad! see white man foot-walk.—Black fellow come—slow, slow—catch all—eat master—eat miss—eat old Jin—eat Nakinna—all! all!"
