A. HENTY.# "Surely Mr. Henty should understand boys' tastes better than any man living."--_The Times._ _THE YOUNG CARTHAGINIAN:_ A Story of the Times of Hannibal. By G. A. HENTY. With 12 full-page Illustrations by C. J. STANILAND, R.I. Crown 8vo, cloth elegant, olivine edges, 6_s._ When boys at school read of the history of the Punic Wars their appreciation of the merits of the struggle between the Romans and Carthaginians is usually slight. That it was at first a struggle for empire, and afterwards one for existence on the part of Carthage, that Hannibal was a great and skilful general, that he defeated the Romans at Trebia, Lake Trasimenus, and Cannae, and all but took Rome, and that the Romans behaved with bad faith and great cruelty at the capture of Carthage, represents pretty nearly the sum total of their knowledge. To let them know more about this momentous struggle for the empire of the world Mr. Henty has written this story, which not only gives in graphic style a brilliant description of a most interesting period of history, but is a tale of exciting adventure sure to secure the interest of the reader. _THE LION OF THE NORTH._ A Tale of Gustavus Adolphus and the Wars of Religion. By G. A. HENTY. With 12 full-page Illustrations by JOHN SCHOENBERG, in black and tint. Crown 8vo, cloth elegant, olivine edges, 6_s._ In this story Mr. Henty gives the history of the first part of the Thirty Years' War, a struggle unprecedented in length, in the fury with which it was carried on, and in the terrible destruction and ruin which it caused. The issue had its importance, which has extended to the present day, as it established religious freedom in Germany. The army of the chivalrous King of Sweden, the prop and maintenance of the Protestant cause, was largely composed of Scotchmen, and among these was the hero of the story. The chief interest of the tale turns on the great struggle between Gustavus and his chief opponents Wallenstein, Tilly, and Pappenheim.
