Read the excerpt from Through the Looking-Glass by Lewis Carroll. “You see,” he went on after a pause, “it’s as well to be provided for EVERYTHING. That’s the reason the horse has all those anklets round his feet.”
“But what are they for?” Alice asked in a tone of great curiosity.
“To guard against the bites of sharks,” the Knight replied. “It’s an invention of my own. And now help me on. I’ll go with you to the end of the wood—What’s the dish for?”
“It’s meant for plum-cake,” said Alice.
“We’d better take it with us,” the Knight said. “It’ll come in handy if we find any plum-cake. Help me to get it into this bag.”

This took a very long time to manage, though Alice held the bag open very carefully, because the Knight was so VERY awkward in putting in the dish: the first two or three times that he tried he fell in himself instead. “It’s rather a tight fit, you see,” he said, as they got it in a last; “There are so many candlesticks in the bag.” And he hung it to the saddle, which was already loaded with bunches of carrots, and fire-irons, and many other things.
