From the result of my observations, it appears that the insects are only found in such multitudes on these insulated and peculiar masses of granite; for about the other solitary granite rocks, so profusely scattered over the range, I did not observe a single moth, or even the remains of one. Why they should be confined only to these particular places, or for what purpose they thus collect together, is not a less curious than interesting subject of inquiry. Whether it be for the purpose of emigrating, or any other cause, our present knowledge cannot satisfactorily answer.[102] The view from this second group was open to the southward, and was a continued series of densely-wooded ranges, differing in their degrees of elevation. When standing on these enormous masses of granite, I thought some of the most distant mountains, in a south-west direction, appeared, some covered and others streaked with snow: I was correct; for the beautiful clearness of the weather had afforded me a view of the “Snow Mountains,” the existence of which has been doubted by many. Whilst looking at them, one of the blacks came near me, and pointing in their direction, informed me, in English, it was snow.[103] The Bugong moths, as I have before observed, collect on the surfaces and also in the crevices of the masses of granite in incredible quantities: to procure them with greater facility, the natives make smothered fires underneath those rocks about which they are collected, and suffocate them with smoke, at the same time sweeping them off frequently in bushels-full at a time. After they have collected a large quantity, they proceed to prepare them, which is done in the following manner.
