After our return from exploring the great cavern, we entered the smaller one; [B in the diagram;] its extent is limited, but the stalactites within were of great beauty and variety of forms; my attention was here attracted by the multitude of small bones mingled with dust, which lay near and about the entrance of this cavern; how they came in this situation merits enquiry, for here alone did I observe them; they appeared belonging to some animals of the _Rodentia_ family, consisting of skulls and other portions of the skeleton, some, indeed nearly the whole, were in a perfect condition: near the spot I picked up a small mass of stalactite, which appeared to have been broken off from some portion of the cavern, but its exact position I could not discover, in which small bones, similar to those scattered about, were imbedded. The specimen I preserved and sent to England.[85] The atmosphere of the inner chamber of the large cavern is at times so close and confined as to produce sickness and violent head-ache, and cause many to faint who visit it, but we experienced no inconvenience, for although a hot wind blew outside from the north-east in strong and oppressive gusts, the inside of the cavern was cool and agreeable. The length of the cavern may, at a guess, be one hundred and twenty yards, or even more; and the large entrance is about sixty yards distant from the Murrumbidgee river. The view, from the front of the cavern, of the exterior country was beautiful: swallows’ nests, as well as the restless birds themselves, were numerous; and the “Currijong-tree” was also seen growing about the limestone ranges. The swamp oaks, or “Plow’y,” of the aborigines grew here in abundance, indicating by their presence the course of the river. The aborigines will not venture into the dark recesses of the cavern for fear of the “dibbil-dibbil,” as they express it. In a small cave attached to this cavern a number of human bones had recently been found, which it was afterwards ascertained were those of a native female, and had been deposited here, (in accordance with a custom among the aborigines of placing the bodies of deceased friends and relations in caverns, hollow trunks of trees, &c.) about twenty years before.
