When the late Lord Tennyson wrote that he : "
Saw the heavens filled with commerce, argosies of magic sails, Pilots of the purple twilight, dropping down with costly bales."
he was perhaps a better prophet than poet. Even he would be surprised to hear that £70,000,000 is invested in the aircraft industry in the United States and that every country in the world (with ourselves in a very modest position in rear) is taking to flying with an enthusiasm which grows month by month. Capt. J. Laurence Pritchard's The Book of the Aeroplane (Longmans, Green, 7s. 6d.) is now issued in a new edition with much new matter. As Secretary_ to the Royal Aeronautical Society, the author is in an excellent position to keep in touch with all the latest developments in design and
he has produced a thoroughly practical and up-to-date book, well-illustrated and giving a complete conspectus of the history, principles, and progress of aviation.
