"Mr. Manville Fenn has here hit upon a capital idea.... This is among the best of the boys' books of the season."--_The Times._ "This sort of book encourages independence of character, develops resource, and teaches a boy to keep his eyes open."--_Saturday Review._ "We can conceive of no more attractive present for a young naturalist."--_Land and Water._ "The late Lord Palmerston used to say that one use of war was to teach geography; such books as this teach it in a more harmless and cheaper way."--_Athenaeum._ #BY HARRY COLLINGWOOD.# "Mr. G. A. Henty has found a formidable rival in Mr. Collingwood."--_Academy._ _THE LOG OF THE "FLYING FISH:"_ A Story of Aerial and Submarine Peril and Adventure. By HARRY COLLINGWOOD. With 12 full-page Illustrations by GORDON BROWNE. Crown 8vo, cloth elegant, olivine edges, 6_s._ In this story the aim of the author has been, not only to interest and amuse, but also to stimulate a taste for scientific study. He has utilized natural science as a peg whereon to hang the web of a narrative of absorbing interest, interweaving therewith sundry very striking scientific facts in such a manner as to provoke a desire for further information. Professor Von Schalckenberg constructs a gigantic and wonderful ship, appropriately named the _Flying Fish_, which is capable of navigating not only the higher reaches of the atmosphere, but also the extremest depths of ocean; and in her the four adventurers make a voyage to the North Pole, and to a hitherto unexplored portion of Central Africa. In common with all this author's stories, "The Log of the Flying Fish" is thoroughly healthy and unexceptionable in tone, and may be unhesitatingly placed in the hands of "our boys," who will enjoy in its perusal a literary treat entirely after their own hearts. _THE CONGO ROVERS:_ A Tale of the Slave Squadron. By HARRY COLLINGWOOD. With 8 full-page Illustrations by J. SCHOENBERG, in black and tint. Crown 8vo, cloth extra, 5_s._ The scene of this tale is laid on the west coast of Africa, and in the lower reaches of the Congo; the characteristic scenery of the great river being delineated with wonderful accuracy and completeness of detail. The hero of the story--a midshipman on board one of the ships of the slave squadron--after being effectually laughed out of his boyish vanity, develops into a lad possessed of a large share of sound common sense, the exercise of which enables him to render much valuable service to his superior officers in unmasking a most daring and successful ruse on the part of the slavers. "Mr. Collingwood carries us off for another cruise at sea, in 'The Congo Rovers,' and boys will need no pressing to join the daring crew, which seeks adventures and meets with any number of them in the forests and pestilential fogs of the Congo."--_The Times._
