THE GREAT FIRE OF LONDON
London in the middle of the seventeenth centure was a city of narrow dirty streets. Indeed the streets were so narrow that it was often possible for a person at the window at one side of the street to shake hands with a neighbor in the house across the street. There was little light and air in London's streets. So that it is not strange that the great epidemic of the plague began in 1665. It was a sad time for London. There were no people in the streets, shops were closed and there were few boats on the Thames. Every house in which there were sick people was shut up and nobody was allowea to go in or out. The doors of such houses were marked with red marks. The following year the Great Fire took place. It began late on Saturday noght in a street not far from London Bridge. The summer of that year was dry, a hot wind was blowing and the fire spread very quickly. The Fire was going on for 5 days and destroyed the greater part of the city.
