The houses were cleaned and whitewashed, the streets were cleansed, and large fires were lit to burn up any rubbish that might still hold infection. St. Paul's Cathedral was cleaned out, and the beds that the patients had used were burned, and all seemed better.
Then happened another terrifying thing, even more alarming than the plague to the unfortunate people who lived in London at that time. One night, when everyone had gone to bed, the church bells in the city began tolling, and soon feet were heard hurrying on the streets; cries of alarm woke even the laziest, and everyone hurried out to see what was the matter. Against the darkened evening sky they saw a lurid colour like a crimson flag, and this changed and waved as columns of smoke passed in front of it; there was no doubt that a big fire had been lighted somewhere.
At first some may have thought this was only one of the bonfires that the police had lighted to burn up the rubbish, but they soon found it was much worse than that. Whole streets were on fire and burning, and, worse than all, a strong wind was blowing the flames right over London.
The houses then were nearly all of wood, and, being old, were very dry. They burned splendidly; no man could have made a better bonfire. The flames seemed alive; they leaped from one to the other, they licked up the woodwork on the gable fronts, they danced into the windows and in at the doors--no one could stop them or save the houses once they had been touched. The great red demon Fire licked up house after house as if he swallowed them with his great red mouth, and the more he ate the more he wanted; his appetite grew larger instead of less. There were only old fire-engines, not like those we have to-day, and water was very scarce, and at first the people stood terrified, staring stupidly, and then began to run away. It was not for some time that the authorities thought of pulling down some houses so as to make a gap over which the great red flames could not leap. But it is not easy work to pull down houses, and before it could be done the flames leaped on again and again and drove them back. At first the poor people whose houses had caught fire threw their furniture and goods into the streets to save them. But they very soon saw this was no use; the flames got them just the same, for there was no time to carry the goods away, and what the flames did not get thieves in the crowd seized and ran away with.
