Alfred William Howitt,
Native Tribes of South-East Australia
(1904)
“ With the Gringai a messenger can pass in safety from one tribe to another. The red-coloured net which is worn round the forehead is usually an emblem for calling the tribe together. When a messenger is within sound of the camp to which he is sent, he gives a particular "coo-ee," when all hearing it assemble to hear what he has to say, but not a word is spoken to him till he thinks it proper to unburden his message, and sometimes he sits quite silent for a long time. When, however, he unburdens his mind, his eloquence is wonderful, and he is listened to with the greatest attention. ”
