had built up a system of thought designed to immure the swathed form of material philosophy from all rays and all sounds of a world not material, as the walls of some blind mausoleum shut out, from the mummy within, the whisper of winds and the gleaming of stars. And did not those very theorems, when carried out to their strict and completing results by the close reasonings of Hume, resolve my own living identity, the one conscious indivisible me, into a bundle of memories derived from the senses which had bubbled and duped my experience, and reduce into a phantom, as spectral as that of the Luminous Shadow, the whole solid frame of creation? While pondering these questions, the storm whose forewarnings I had neglected to heed burst forth with all the suddenness peculiar to the Australian climes. The rains descended like the rushing of floods. In the beds of watercourses, which, at noon, seemed dried up and exhausted, the torrents began to swell and to rave; the gray crags around them were animated into living waterfalls. I looked round, and the landscape was as changed as a scene that replaces a scene on the player's stage. I was aware that I had wandered far from my home, and I knew not what direction I should take to regain it. Close at hand, and raised above the torrents that now rushed in many a gully and tributary creek, around and before me, the mouth of a deep cave, overgrown with bushes and creeping flowers tossed wildly to and fro between the rain from above and the spray of cascades below, offered a shelter from the storm. I entered,--scaring innumerable flocks of bats striking against me, blinded by the glare of the lightning that followed me into the cavern, and hastening to resettle themselves on the pendants of stalactites, or the jagged buttresses of primaeval wall. From time to time the lightning darted into the gloom and lingered amongst its shadows; and I saw, by the flash, that the floors on which I stood were strewed with strange bones, some amongst them the fossilized relics of races destroyed by the Deluge. The rain continued for more than two hours with unabated violence; then it ceased almost as suddenly as it had come on, and the lustrous moon of Australia burst from the clouds shining bright as an English dawn, into the hollows of the cave. And then simultaneously arose all the choral songs of the wilderness,--creatures whose voices are heard at night,--the loud whir of the locusts, the musical boom of the bullfrog, the cuckoo note of the morepork, and, mournful amidst all those merrier sounds, the hoot of the owl, through the wizard she-oaks and the pale green of the gum-trees.
