In others the dialects are so totally unlike one another, that natives, meeting upon opposite sides of a river, cannot speak to or understand a word of what each other say, except through the medium of a third language, namely that spoken by the natives of the river itself, and which is totally unlike either of the other two.
This is the case at Moorunde, where three different dialects meet, the Yakkumban, or dialect spoken by the Paritke tribe, or natives inhabiting the scrub to the west and north-west of the Murray.

The Boraipar or language of the Arkatko tribe, who inhabit the scrub to the east of the Murray, and the Aiawong or river dialect, extending, with slight variations, from the junction of the Murray and Lake Alexandrina to the Darling..
