 28 —on account of the way it waves its tail, swimming, I imagine. That's what I went on this last voyage for, to get that. You see I'm very busy just now trying to learn the language of the shellfish. They have languages, of that I feel sure. I can talk a little shark language and porpoise dialect myself. But what I particularly want to learn now is shellfish."

"Why?" I asked.

"Well, you see, some of the shellfish are the oldest kind of animals in the world that we know of. We find their shells in the rocks—turned to stone—thousands of years old. So I feel quite sure that if I could only get to talk their language, I should be able to learn a whole lot about what the world was like ages and ages and ages ago. You see?"

"But couldn't some of the other animals tell you as well?"

"I don't think so," said the Doctor, prodding the sausages with a fork. "To be sure, the monkeys I knew in Africa some time ago were very helpful in telling me about bygone days; but they only went back a thousand years or so. No, I am certain that the oldest history in the world is to be had from the shellfish and from them only. You see most of the other animals that were alive in those very ancient times have now become extinct."

"Have you learned any shellfish language yet?" I asked.
