PICCADILLY, WITH THE GREEN PARK.
That part of Piccadilly which overlooks the Green Park is chiefly remarkable for its numerous Clubs and palatial private houses, notable among the latter being Devonshire House and Apsley house. Our view, looking west the beginning of the hill, embraces several Clubs, of which the best known are the New Travellers', situated at the further corner of the first turning (a short cut to Curzon Street), and the Junior Constitutional, the splendid, manv-storeyed building further west. Piccadilly does not rank so high in Clubland, of course, as Pall Mall, but the outlook over the Green Park - so verdant and well-timbered - and St James's Park towards Westminster is pleasant in the extreme. The Green Park is some sixty acres in extent.
