Note

"Un-dum-gar" for a station near Mt Lindesay is more nearly
correct than the usual "Unumgar" though it always seemed
to me more like "Un-tum-gar, or a sound between d and
t if such a sound is possible to anybody but a
blackfellow. The late J.C. Edwards of Roseberry
gave me the name for Kyogle as "Curroka", not
"Cha-wy-bin". It is possible there may have been two
names, one for the mountain (Fairymount) and
one for Fawcett's Plain. Kyogle ( a bustard,
or plain turkey) was originally the name of
Runnymede Plain until Mr Alex Mackellar shifted it.
I prefer "T'chal-gum-buin" for Mt Lindesay. I have heard
it very often from the Richmond River blacks.
