The World in 2030 A.D.

It is the purpose of the Essays which follow to attempt a series of speculative predictions dealing with the possible development of the world during the next hundred years. If one looks back a hundred years and so looking compares the world of that day with the world of to-day, one becomes almost equally conscious of the equal risk of under-estimating and of over-estimating the developments which lie in front of us. Remembering these and a thousand other changes, mechanical, ethical, social, political and constitutional, we shall, it may be repeated, be wise to declare little impossible in the hundred years in which our sons and grandsons will live. The effort to predict an unknowable future must always possess a fascination of its own. In the slight essays which are collected in this volume I follow - *longum post intervallum* - in the footsteps of Jules Verne, Bellamy, Wells and Haldane. For these reasons I put these Essays forward without undue assurance. That many of the changes herein predicted will be realised is certain. Others, no doubt, will hardly escape the smile which is given to phantasy.
