From this he was released prematurely through the good offices of a gentleman who pitied him, only to be reimprisoned, but in Newgate, not the hulks, for fresh robberies at the Opera House, Pantheon, and other places of public resort. Once more released, he betook himself to his old evil courses, and having narrowly escaped capture in London, wandered through the northern counties in various disguises, till he was at length taken at Newcastle-on-Tyne. Another narrow escape followed, through the absence of a material witness; but he was finally arrested for picking a pocket on Epsom Downs, and sentenced to seven years' transportation. He made an affecting speech at his trial, urging, in extenuation of his offence, that he had never had a fair chance of earning an honest livelihood. He may have been sincere, and he certainly took the first opportunity offered to prove it. On the voyage out to New South Wales there was a mutiny on board the convict ship, which would have been successful but for Barrington's aid on the side of authority. He held the passage to the quarter-deck single-handed, and kept the mob of convicts at bay with a marline-spike, till the captain and crew were able to get arms and finally suppress the revolt. As a reward for his conduct, Barrington was appointed to a position of trust, in charge of other prisoners at Paramatta. Within a year or two he was advanced to the more onerous and responsible post of chief constable, and was complimented by the governor of the colony for his faithful performance of the duty. He fell away in health, however, and retiring eventually upon a small pension, died before he was fifty years of age.
