Black Cargo

THE SLAVE SHIP-- Mary Johnston-- Little, Brown ($2.00). One of those slow-moving but inevitable groundswells of approval-- the usual reward of sound, unspectacular workmanship-- has gathered behind Mary Johnston's sombre study of the 18th Century slave trade. The tale is David Scott's, told in his own burred words. A young Scotch Jacobite, he fell in with the dark traffic upon escaping from penal indenture in Virginia. The evils of that traffic, the crime of the hideous Middle Passage, bore heavy on his Scotch conscience.
