“Why did you have your toe-nails cut, your skin oiled, and your feet sand-papered?” asked Sally of an elephant in the Zoo.
“One question at a time please,” said the elephant. “I can’t answer all three at once, for then the answers would be all jumbled up. Besides, I don’t know how to say more than one word at a time.
“My nails were cut because they needed it. And, come to think of it, I can answer all your questions at once. My feet needed to be sand-papered and my body needed to be oiled. My skin required it, and so the keeper looked after me, as he did after my friends here.” This he said waving his trunk.
“But what do you do when you are not in the Zoo?” asked Sally. “They don’t have sandpaper and nail scissors in the jungles, do they?”
“Ah, that is where you do not understand, and where the keeper does. In the wilds I can cut my nails on the great rocks. They keep them short. Here I cannot do it myself, and so the keeper has to do it for me. And I get the oil for my skin in the swamps when I’m free, and my feet are kept hard by the ground and rocks. We do not need the keeper’s scissors and so forth when we are free, for old Mother Nature looks after those things for us.”
