Orphanage to the right and the Warehousemen's and Clerks' School on Russell Hill to the left. Guide-books remind us how here Horne Tooke wrote his _Diversions of Purley_; but contemporary Radicals seem not much disposed to seek either amusement or instruction from the works of that philosophic grammarian and agitator. What will interest the present generation more is an effort to preserve Purley Beeches, a fine woodland on the Downs, as pleasure-ground for this fast-growing suburb. On the east, beyond the railway, beside a face of quarried chalk, opens the Caterham valley, its hollow and its south side much choked up with streets and mansions, strung together by two railway lines; but the north slope opens in the steeps of Riddlesdown, where a thousand acres are preserved as a London park, with tea-gardens and other attractions much in favour with school-treat parties; and in the background, by a path to Warlingham, may perhaps be found a strong encampment of gypsies. The last time I passed that way, on a fine Sunday evening, I came upon a band of "burly chiels and clever hizzies" from the North, actually dancing about a piper--"to give them music was his charge," as more rigid Scots might quote grimly. The waters by which these cheerful exiles thus forgot the Sabbath songs of their Zion show, in the reservoirs of Kenley and Purley, a strikingly blue tint one guesses to be due to some process for softening their chalky impregnation; and this valley also has a subterranean bourne, to which fond tradition gives a periodicity of seven years. Again a word to the unshackled wanderer: let him pass up by the curving face of Riddlesdown and through the lower part of Caterham, past the Congregational College, then by a track up the Harestone valley, leading to a high brow of the Downs at the War Coppice. The Caterham valley itself is some hundreds of feet above the sea, so no wonder that so many well-to-do Londoners make their nests about what a local guide styles "its cluster of ambrosial hills." At Purley begins the long tram line that takes us through Croydon, and on to Norbury by still open spaces, shrinking like Balzac's _Peau de chagrin_, where the footpaths that run off to the heights of Norwood may any year be found hedged by houses. Croydon ought to be well equipped with trams, for one of the first in the country was made hence to Wandsworth, the very first, in 1800, belonging to Derbyshire, the contrivance of Benjamin Outram, from whose name _Outramways_ is said to have been playfully derived; but the word tram is of course an old one. There is now only one hiatus, at Streatham, in the electric tram route from the Chalk Downs to the Thames bridges; and that seems like to be bridged over, for Croydon is running into London as fast as its own satellites, Purley, Sanderstead, Thornton Heath, and Beddington are drawn into the growing mass of Croydon.
