Aeolus, or the Future of the Flying Machine. By Oliver Stewart.

“Both his wit and his expertness save him from the nonsensical-fantastic. There is nothing vague or sloppy in these imaginative forecasts.”—Daily News. “He is to be congratulated. His book is small, but it is so delightfully funny that it is well worth the price, and there really are sensible ideas behind the jesting.”—Aeroplane.

Stentor, or the Press of To-Day and To-Morrow. By David Ockham.

“A valuable and exceedingly interesting commentary on a vital phase of modern development.”—Daily Herald. “Vigorous and well-written, eminently readable.”—Yorkshire Post. “He has said what one expects any sensible person to say about the ‘trustification’ of the Press.”—Spectator.

Rusticus, or the Future of the Countryside. By Martin S. Briggs, F.R.I.B.A.

“Few of the 50 volumes, provocative and brilliant as most of them have been, capture our imagination as does this one.”—Daily Telegraph. “The historical part is as brilliant a piece of packed writing as could be desired.”—Daily Herald. “Serves a national end. The book is in essence a pamphlet, though it has the form and charm of a book.”—Spectator.

Janus, or the Conquest of War. By William McDougall, M.B., F.R.S.

“Among all the booklets of this brilliant series, none, I think is so weighty and impressive as this. It contains thrice as much matter as the other volumes and is profoundly serious.”—Dean Inge, in Evening Standard. “A deeply interesting and fair-minded study of the causes of war and the possibilities of their prevention. Every word is sound.”—Spectator.
