IV., where we read the following:

"SANDALS.
"Arunta Tribe.

"KURDAITCHA SHOES.--When a native for some reason desired to kill a
member of another camp or tribe, he consulted the medicine man of his
camp, and arrangements were made for a 'Kurdaitcha Luma.' . . . Both
medicine man and Kurdaitcha wore remarkable shoes. These had the form of
a long pad made of human hair, with numberless emu feathers intertwined,
and with a certain amount of human blood to act as a cementing substance.

" . . . Both ends of the shoes were rounded off, and were exactly similar
to one another, which has given rise to the erroneous idea that their
object was to prevent the wearer being tracked . . ."

But no other explanation is offered.

Breaden says tracks of a man wearing these emu-feather shoes are very
indistinct, but has no certain knowledge of their use. Warri, looking at
the bark sandals, said, "Black-fella wear 'em 'long a hot sand."
Questioned about the emu-feather shoes, he gave the usual answer, "I
dunno," and then added, probably to please me, as I had suggested the
explanation, "Black-fella no more see 'em track, I think."

It was clear that no good results were likely to follow further search in
this locality, for the tracks were so numerous, and crossed and recrossed
so often, that nothing could be made out of them. The country to the
North being so uninviting, I altered our course to North-East, and again
to North, when we sighted a smoke, and, following tracks, camped on them.
