Messrs. Backhouse and Walker, of the Society of Friends, travelled these colonies (1831 to 1836), chiefly engaged in religious labors, and principally to admonish the prisoners. The volume, of which Backhouse was the author, attests their industry and accurate observation, while performing a mission, which the moral weight of their connections rendered of great moment. To understand this record of their labors, some acquaintance with science is requisite, and not less a knowledge of quaker modes of thought. The adventurous and buoyant spirit of the writer, which carried him into odd situations, is sometimes irresistibly droll, in contrast with formal phrases. He was a gentleman of prudence and sagacity: "he lifted up his heart to God; took his pocket compass," and thus escaped some perils, both by sea and land; and carried to England a reputation, from which detraction has taken nothing, and which friendship would scarcely desire to improve. The capture of the _Cyprus_ in Recherche Bay, on the voyage to Macquarie Habour, was a stirring episode in the history of transportation. It excited vast interest in Great Britain, and was dramatised at a London theatre. The prisoners, who wage war with society, regarded the event with exultation; and long after, a song, composed by a sympathising poet, was propagated by oral tradition, and sung in chorus around the fires in the interior. This version of the story made the capture a triumph of the oppressed over their oppressors. The stanzas set forth the sufferings of the prisoners by the cruelty of their masters, who they vainly attempted to please. It related their flight from torture to the woods, and drew but a dreary picture of the life of an outlaw. It passed through the details of conviction and embarkation, and then described the dashing seamanship of the pirates in managing the bark, once destined to carry them to that place of suffering; but which bore "bold Captain Swallow" to the wide ocean and liberty. Such was the song; but the facts were different. In August, 1829, thirty-one prisoners embarked on board the _Cyprus_; among them was Swallow, a seaman, who eighteen years before had cut out a schooner at Port Jackson, and was afterwards transported to Van Diemen's Land in the _Deveron_, Captain Wilson.
