...

The steamer Karrakatta left the South Quay at 2 p.m. on August 17 for Singapore, via ports. She took away an unusually large complement of passengers, among whom were Bishop Gibney and the Rev. Father Martelli, who are going to Broome.

...

AB notes:

There is not mention of Daisy Bates being aboard, but that is reasonable. Her invitation to come to Beagle Bay came late.
