To extinguish (熄滅) different kinds of fires, several types of fire extinguishers have been invented. They must be ready for immediate use when fire breaks out. Most portable (手提式的) kinds operate for less than a minute, so they are useful only on small fires. The law requires ships, trains, buses and planes to carry extinguishers.

Since fuel, oxygen (氧氣) and heat must be present in order for fire to exist, one or more of these things must be removed or reduced to extinguish a fire. If the heat is reduced by cooling the material below a certain temperature, the fire goes out. The cooling method is the most common way to put out a fire. Water is the best cooling material because it is low in cost and easy to get.

Another method of extinguishing fire is by cutting off the oxygen. This is usually done by covering the fire with sand, steam or some other things. A blanket may be used do cover a small fire.

A third method is called separation, which includes removing the fuel, or material easy to burn, from a fire, so that it can find no fuel.

The method that is used to put out a fire depends upon the type of fire. Fires have been grouped in three classes. Fires in wood, paper, cloth and the like are called Class A fires. These materials usually help keep the fire on. Such fires can be stopped most readily by cooling with water.

Childhood was an illusion (錯覺) and the illusion was this: everything was bigger. No, I mean everything, not just houses and shops and grown-ups, but colors and flowers and journeys, especially journeys which seemed endless. “Are we there yet, Daddy?”

Funfairs (游樂場) were huge things that spread for miles around you with noise and lights and exciting danger. Rainy days at home when you were ill seemed to last for ever. Being a grown-up yourself was an unthinkable distant possibility. Every sound was louder, every game was grander, every pain unbearable.

As I’ve grown old, life has become smaller. Tastes have bulled. Surprises have turned into shocks. Days go by unnoticed. How can I regain childhood when it was an illusion?

I have only one repeatable and wonderful way and even in this way I can regain only part of that larger world. I can play upon the stage like a child and make the crowd laugh and laugh with them, sometimes helplessly like a child, and then, even though I’m a sixty-one-year-old man, I can almost catch the colors and sounds and stillness of those bigger years when I was little.
