PALL MALL, LOOKING EAST.
Pall Mall is the heart of Club land, and is unique in character and associations. On the south side, at the corner of Waterloo Place, is the Athenaeum Club; and beyond this are the Travellers', the Reform, and the Carlton Clubs, the War Office, Marlborough House, and St. James's Palace while, on the opposite side, are more clubs- notably the Junior Carlton and the Army and Navy. The name is a corruption of "pail mail," a game not unlike croquet, introduced into this country by Charles I. For hundreds of years the district has been a fashionable promenade; and its sweet shady side has been sung by the poet. Our view shows it on Levée day, when a crowd always assembles opposite St. James's Palace, and a special force of constables is required to regulate the traffic.
