So quick and so emphatic is the transition from one region to the other--from the region of lonely car drives to the snug neighbourhood of gas and steam. But let me define or describe the limits. If instead of going out by road you take either the train from Harcourt Street, which skirts the base of the hills, or the Westland Row line, which follows the sea all the way through Kingstown and Killiney till both lines meet in Bray, you will, of course, have suburbs about you, merging into villadom: and the suburbs continue on the sealine almost unbroken to Killiney. Then comes a gap, and at Bray you have a considerable town, from which villadom--a very pleasant and cultivated villadom--extends towards the hills. Beyond Bray, the line rounds the face of Bray Head in a series of little tunnels, with intervening glimpses of sea dashing below, in the best Riviera manner; and then you come to Greystones, another even more suburban settlement. I set Greystones--some fifteen miles south of Dublin--as the suburban limit: beyond that you have honest country--Wicklow proper. Only, let it be clearly understood that this is no disparagement. The most beautiful things in Wicklow are outside what I call Wicklow proper, and inside Dublin's "sphere of influence". These I now proceed to describe. First of all, there runs up from Bray the famous Dargle, a steep wooded glen with the river dividing two demesnes--Lord Monk's and Lord Powerscourt's. For miles you can drive or walk through a scene of constantly varying beauty, with glimpses of mountain behind the wooded slopes, until at last you come to the Powerscourt Waterfall with its plunge of a hundred feet out of an upper ravine. Climb round, get above the waterfall, and at last, on the slopes of Douse Mountain, you reach wild nature--and you forget Dublin. Till then the spirit of Dublin is with you--the spirit of a prosperous Dublin, inhabited by rich men who liked to adorn the countryside with some of the graces of the town, to set elaborate plantations of foreign shrubs against a backing of rock and heather. Very pretty it is, and nowhere done more prettily. [Illustration: PORTMARNOCK GOLF LINKS]
