On this slide we have shown again the map of the space covered by the houses of Greater London. The red indicates the area of the houses and streets. The green marks the pieces of tree-covered ground known as parks, which have been retained for the pleasure and health of the people of London. Note the River Thames, like a very broad street, winding through the midst of the town. Note also the docks branching from the river, and the bridges across it. Here, marked with their names, are the two lowest of the bridges--the Tower Bridge and London Bridge. You observe that there are no bridges lower than these, and that all the docks open below bridge. Do you see that London Bridge is still almost exactly in the centre of London? At first the river curved through forests and marshes; then there grew up a little town beside the bridge; that town went on growing larger and larger until it is now as large as a small country. But the head of the sea navigation is still at London Bridge, and the vast metropolis extends in all directions round its harbour. Each day there enter some 700 ships from all parts of the world, many of them from the coasts of England itself, but some from the most distant lands--from America, Africa, the East, and Australia. [Sidenote: 12. Greater London with Central London marked off.] [Sidenote: 13. Central London with the City boundaries.] You see this rectangular space marked off on the map of Greater London? I am next going to give you a map, on a larger scale, of the central and most important part of London; it is contained within the rectangle. Here it is, with the boundary of the City of London shown in red upon it. We see the chief streets, and we are able to mark out the route which we are going to take. We start from the Tower and the Tower Bridge; we pass beneath London Bridge, with the City, the chief business centre, on our right hand; we go under several more bridges and arrive at Westminster, where Parliament sits and the King-Emperor is crowned; then we land, drive past Buckingham Palace, where the King lives, and so to the chief parks. Turning eastward again we return through Trafalgar Square to St. Paul’s Cathedral, which is the Cathedral of London; finally we reach the Bank of England, in the centre of the City, and come back to London Bridge, from whose neighbourhood we started. The whole round measures about eight miles, and yet, as you will remember, the map upon which we have traced it is but the central and smaller part of London. [Sidenote: 14.
