Heroes of the Air

Illustrated in Colour by CYRUS CUNEO; also from photographs.

This book deals with the labours and exploits of those who have played an Important part in bringing about the conquest of the air. It not only contains personal memoirs of the men themselves, but traces the progress of aerial flight from the early gliders to the aeroplanes of to-day. The story of the experiments of those who first essayed to fly--the problems that long baffled them and the difficulties they overcame--together with the accounts of the daring feats of modern aviators, make a stirring narrative, and carry the history of heroism and endurance a stage further forward.

"This will prove a great attraction to a multitude of readers who wish to read of deeds of great daring and very narrow escapes."--Nation.

With the Airmen

Illustrated in Colour by CYRUS CUNEO, and with numerous black-and-white illustrations and diagrams.

Mr. Grahame-White has not only repeatedly proved his skill and daring as a pilot, but the well-known type of biplane bearing his name shows that he is in the forefront of designers and constructors. With his practical and technical knowledge is combined the somewhat rare ability to impart his knowledge in a form acceptable to boys, as he has already shown in his "Heroes of the Air." This time he has written a vade mecum for the young aeroplanist, who is conducted to the aerodrome and initiated into all the mysteries of flying. The structure of the aeroplane, the uses of the different parts, the propulsive mechanism, the steering apparatus, the work at a flying school, the causes of accidents, and the future of the aeroplane are all dealt with.

"It is surely one of the most entertaining books on a technical subject that have ever appeared, as well as one of the most instructive and comprehensive."--Nation.
