Arlington Street is hardly less interesting. There is the home of the Cecils, where one great Prime Minister, Lord Salisbury, could once look across the street at the windows of the house that had sheltered another--Sir Robert Walpole. As the son of the latter once wrote to Montagu: “Nothing can be more dignified than this position.” In the past, as in the present, its houses have been the homes of the illustrious. The street was formed in 1689, and was the property of that Arlington who was one of the “A’s” of the famous (or, shall we say, infamous?) “Cabal.” The Duchess of Cleveland withdrew hither, after the death of Charles had made Cleveland House too costly an abode; the Duchess of Buckingham, wife of that Duke, castigated in Dryden’s best-known lines, and daughter of Fairfax, Cromwell’s henchman; Lady Mary Wortley Montagu, who resided here with her father, the Duke of Kingston; Pulteney, Earl of Bath--as if he could never get away from his enemy, Sir Robert; and Henry Pelham, who lived at No. 17, in the house built by Kent and now Lord Yarborough’s. At No. 21 Lord Sefton gave his famous dinners with Ude as _chef_ in command; and Lord Wimborne’s house, which is already dwarfed by the neighbouring “Ritz,” once belonged to Lord Camden, then to the Duke of Beaufort, and was subsequently sold to the Duke of Hamilton for £60,000; while John Lothrop Motley was renting Lord Yarborough’s house, from 1869-70, during his term of office as United States Minister. If we turn back into St. James’s Street and look down that famous thoroughfare two things cannot fail to strike us--one, the effective screen at the bottom formed by the picturesque clock-tower of the Palace which dates from Henry VIII.’s time; the other, the marked declivity in the ground, which is only comparable with Ludgate Hill, in the East, and is considerably steeper than any part of Piccadilly or Knightsbridge, in the West.
