DEMONS. 63 have often wondered myself what the noise is really caused by, which they ascribe to Mulgewanke. I have heard it dozens of times, and so have many other persons. It resembles the boom of a distant cannon, or the explosion of a blast. Sometimes, however, it is more like the sound made by the fall of a huge body into deep water. It cannot be the peculiar sound made by the Murray bittern, as I have often beard that too, and it is not at all like the noise in the Lake. At first I ascribed it to people blasting wood on the opposite side, hut since then I have been convinced that this cannot be the case.

Once I knew of a man catching his ngaitye in the person of a large female tiger snake, and, after pulling out the teeth, he put it in a basket, and hung it up in his wurley. The nest morning they found that she had brought forth sixteen young ones. This increase of family was too much for those blacks to whom she did not stand in the relation of
