Wooden posts and rails stood round the Fields till 1735, when an Act was passed to enable the inhabitants to make improvements, to put an iron gate at each corner, and to erect dwarf walls and iron palisades.[709] Before this time grooms used to break in horses on this spot. One day while looking at these centaurs, Sir Joseph Jekyll, who had brought a very obnoxious bill into Parliament in 1736 in order to raise the price of gin, was mobbed, thrown down, and dangerously trampled on. His initials, “J. J.,” figure under a gibbet chalked on a wall in one of Hogarth’s prints.[710] Macaulay’s _History_ contains a very highly coloured picture of these Fields. A comparison of the passage with the facts from which it is drawn would be a useful lesson to all historical students who love truth in its severity.[711] Newcastle House stands at the north-west angle of the Fields, at the south-eastern corner of Great Queen Street. It derived its name from John Holles, Duke of Newcastle, a relative of the noble families of Vere, Cavendish, and Holles. This duke bought the house before 1708, but died in 1711 without issue, and was succeeded in the house by his nephew, the leader of the Pelham administration under George II. The house had been bought by Lord Powis about 1686. It was built for him by Captain William Winde, a scholar of Webbe’s, the pupil and executor of Inigo Jones.[712] William Herbert, first Marquis of Powis, was outlawed and fled to St. Germain’s to James II., who made him Duke of Powis. Government had thought of buying the house when it was inhabited by the Lord Keeper, Sir Nathan Wright,[713] and to have settled it officially on the Great Seal. It was once the residence of Sir John Somers, the Lord Chancellor. In 1739 Lady Henrietta Herbert, widow of Lord William Herbert, second son of the Marquis of Powis, and daughter of James, first Earl of Waldegrave, was married to Mr. John Beard,[714] who seems to have been a fine singer and a most charitable, estimable man. Lady Henrietta’s grandmother was the daughter of James II. by the sister of the great Duke of Marlborough. Dr. Burner speaks of Beard’s great knowledge of music and of his intelligence as an actor.[715] In an epitaph on him, still extant, the writer says-- “Whence had that voice such magic to control? ’Twas but the echo of a well-tuned soul; Through life his morals and his music ran In symphony, and spoke the virtuous man. ... Go, gentle harmonist! our hopes approve, To meet and hear thy sacred songs above; When taught by thee, the stage of life well trod, We rise to raptures round the throne of God.” Beard, excellent both in oratorios and serious and comic operas, became part proprietor of Covent Garden Theatre, and died in 1791.
