In this hook Mr. Strang looks ahead--and other books have already proved him a prophet of surprising skill--to a time when there is a great Mongolian Empire whose army sweeps down on the North-West Frontier of India. His two heroes luckily have an aeroplane, and with the help of a few Pathan miners they hold a pass in the Hindu Kush against a swarm of Mongols, long enough to prevent the cutting of the communications of the Indian army operating in Afghanistan. The qualities which marked Mr. Strang’s story, "The Air Scout," and won extraordinarily high commendation from Lord Roberts, Lord Curzon, and others, as well as from the _Spectator_ and other great journals, are again strikingly displayed; and the combination of thrilling adventure with an Imperial problem and excellent writing, adds one more to this author’s long list of successes. "An exceptionally good book, written moreover in excellent style."--_Times_. "’The Air Patrol’ is really a masterpiece."--_Morning Post_. The Air Scout A Story of National Defence. Illustrated in Colour by W. R. S. STOTT. The problems of National Defence are being discussed with more and more care and attention, not only in Great Britain, but also in all parts of the Empire. In this story Mr. Strang imagines a Chinese descent upon Australia, and carries his hero through a series of exciting adventures, in which the value of national spirit, organisation, and discipline is exemplified. The important part which the aeroplane will play in warfare is recognised, and the thousands of readers who have delighted in the author’s previous stories of aviation will find this new book after their own heart. LORD ROBERTS wrote:--"It is capital reading, and should interest more than boys. Your forecast is so good that I can only hope the future may not bring to Australia such a struggle as the one you so graphically describe." LORD CURZON writes:--"I have read with great pleasure your book, ’The Air Scout.’ It seems to me to be a capital story, full of life and movement: and further, it preaches the best of all secular gospels, patriotism and co-operation." "We congratulate Mr. Strang on this fine book--one of the best fighting stories we have read."--_Morning Post_. ROMANCES BY HERBERT STRANG Palm Tree Island Illustrated in Colour by ARCHIBALD WEBB.
