The city of London was, as we have seen, known in earliest times as the king's "Chamber," and the Chamberlain was the king's officer. The City in fact served as the purse of the nation, until such time as the establishment of the Bank of England did away with the necessity of direct applications to the Corporation for loans, to enable the government of the kingdom to be carried on. Like the nation itself, the City has had its times of pecuniary distress, and nothing but the most careful nursing of its estate has enabled it to tide over its difficulties. More especially was this the case at the close of the civil war, and again, for some years after the Great Fire, as well as at the commencement of the reign of Queen Anne. [Sidenote: The City's public spirit.] The City has not wasted its substance. Large sums have been expended upon local improvements, upon the erection of markets, upon bridges, not forgetting that latest marvel of engineering skill, the Tower Bridge, upon the City's schools, upon the erection of the Guildhall library with its adjacent Museum and Art Gallery, as well as upon the establishment and maintenance of one of the most successful Schools of Music ever known in this country. At the close of the year 1882, the Corporation had, within a comparatively recent period, expended nearly six and a half millions, out of its own funds, upon improvements within the city and liberties--improvements which benefited the inhabitants of the metropolis generally no less than the citizens themselves.[838] Nor has the Corporation stayed its hand at the city's boundaries. During the short period of ten years preceding 1882, a sum of more than £300,000 was expended out of the city's cash for providing open spaces for the people, including Epping Forest, Wanstead Park, West Ham Park, and Burnham Beeches, but irrespective of the later acquisitions of Coulsdon and other adjacent commons in the county of Surrey, since dedicated to the public.[839] An area exceeding 6,000 acres in all, has thus been preserved for posterity and placed beyond risk of purprestures and encroachments. [Sidenote: The City and the Metropolitan Board of Works.] From the time when the Metropolitan Board of Works was first established in 1855, down to its disestablishment in 1889, the Corporation contributed large sums of money to assist that body in carrying out the stupendous work of the Thames Embankment, a work of which Londoners may well be proud, and were engaged jointly with the Board in freeing from toll the bridges of Staines, Walton, Hampton Court, Kingston and Kew, on the Thames, as well as Tottenham Mills and Chingford bridges on the Lea.
