Thomson and J.Key, Js.P., in the Fremantle Police Court this morning on a charge of being a rogue and vagabond, by having been found sleeping in a boat shed at East Fremantle. Constable O'Shea said the man had been drinking about East Fremantle during the past two weeks, doing no work, and it was in consequence of a report that witness proceeded to the boat shed yesterday morning and found him. In answer to the Bench, White said he came from Sydney, and had been in a circus but got stranded at Fremantle. Sergeant Smythe said the youth was convicted in Perth last year for unlawful possession, and was a "ne'er do well."

The bench in sentencing White to 7 days imprisonment, advised him to get out of the country, when he was released.https://trove.nla.gov.au/newspaper/article/256701580The previous conviction in Perth...
