This is a change in human conditions that has been a very distinctive event in the history of the past century, and it is still in progress. But I think there is excellent reason for supposing that for practical purposes this change, made by the railway and the motor, this development of local locomotion, will reach a definite limit in the next hundred years. We are witnessing the completion of a great development that has altered the average possible suburban journey in an hour from one of four or five miles to one of thirty miles, and I doubt very much whether, when every tendency of expansion has been reckoned with, this average hour journey will ever get much beyond sixty or seventy miles an hour. A radius of four or five miles marked the maximum size of the old community. A radius of a hundred miles will certainly mark the maximum of the new community. And so it is no effectual answer to my general argument to say that a revision of administrative areas always has been and always will be a public necessity. To a certain extent that always has been and always will be true, but on a scale in no way comparable to the scale on which it is true to-day, because of these particular inventions. This need in its greatness is a peculiar feature of the present time, and a peculiar problem of the present time. The municipal areas that were convenient in the Babylonian, ancient Egyptian, or Roman empires were no larger and no smaller than those that served the purpose of seventeenth-century Europe, and I believe it is highly probable--I think the odds are in favour of the belief--that the most convenient administrative areas of the year 2000 will be no larger and no smaller than those for many subsequent centuries. We are, in this respect, in the full flow of a great and permanent transition. And the social and political aspect of the change, is this steadily increasing proportion of people--more especially in our suburban areas--who are, so far as our old divisions go, delocalized. They represent, in fact, a community of a new sort, the new great modern community, which is seeking to establish itself in the room of the dwindling, little, highly localized communities of the past.
