Some sixteen years ago I endeavoured to interest the inhabitants of the district where I live in the possibilities of the then newly-passed Town-Planning Act. The more enlightened among them readily responded, but there were some who said that this was a rural area and that they had no wish to see it turned into a town. Since then it _has_ turned itself into something resembling a town, but its growth has been spasmodic and irregular. A few years later came a proposal to acquire two fields in the centre of the district for a public park. Again the objectors appeared; what does a semi-village need with a public park, at a high price too? Fortunately the fields were acquired, and already they are nearly encircled by building plots. Meanwhile a great Arterial Road has been driven right across the new park, cutting it in half and reducing its attractions. Under a proper town-planning scheme such things would be impossible. Roads and parks would be laid out on paper years before they were required; and, though modifications of the first plan would become necessary from time to time, the ultimate gain would be enormous. Groups of adjoining authorities are already preparing regional town-planning schemes in concert, so that trunk roads may be provided in such a way as to pass through each area to its benefit and not to its detriment. If “Rusticus” stands too long while the river flows by, as the quotation on my title-page suggests, he will find the countryside engulfed. In my last chapter something was said of the possibilities that the new science of Town-planning has to offer us, as a result of many years’ experience and experiment. We have seen the appearance of innumerable municipal housing-schemes, of “Satellite Towns” like Letchworth and the new Welwyn, of model industrial communities like Bournville and Port Sunlight, of communal efforts like the Hampstead Garden Suburb, of many admirable achievements in the developments of private enterprise. Originating at the time (1876 _et seq._) when Bedford Park was laid out, the idea developed slowly before the War and has made great strides since. It is one of the brightest spots in the history of English progress, but it has not been sufficient to stem the rush of _ersatz_ building that followed the War.
