The old smuggling days! What visions are called up by the name--of stratagems, and caves, and secret passages, and ding-dong fights between sturdy seamen and dashing King's officers! It is in these brave days of old that Mr. Herbert Strang has laid the scenes of his story "Jack Hardy." Jack is a bold young middy who, in the course of his duty to the King, falls into all manner of difficulties and dangers: has unpleasant experiences in a French prison, escapes by sheer daring and ingenuity, and turns the tables on his captors in a way that will make every British boy's heart glow. "Herbert Strang is second to none in graphic power and vivacity ... Here is the best of characterization in bold outline."--_Athenæum_. King of the Air: or, To Morocco on an Airship Illustrated in Colour by W. E. WEBSTER. Crown 8vo, cloth extra, 2/6 Lord of the Seas: A Story of a Submarine. Illustrated in Colour by C. FLEMING WILLIAMS. Crown 8vo, cloth extra, 2/6. The present day is witnessing a simultaneous attack by scientific investigation on the problems of aerial and submarine locomotion. In "King of the Air" Mr. Strang gives us a romance of modern aeronautics. In "Lord of the Seas" we have a companion volume dealing with the marvels of submarine navigation. "Without doubt Mr. Strang is at the top of his profession. 'The King of the Air' is one of the best boys' books in print, and Mr. Strang has given us an excellent companion in 'Lord of the Seas.'"--_Dundee Advertiser_. Swift and Sure: The Story of a Hydroplane. Crown 8vo, cloth extra 2/6. What the aeroplane is to the air the hydroplane promises to be to the sea. This story, a pendant to the two preceding books, is a forecast of what may be expected from the progress of mechanical invention. HERBERT STRANG'S HISTORICAL SERIES Crown 8vo.
