"These are only vegetables," said the philosopher. "They are
alive, but not at all interesting."

"I don't know about that," said the stranger. "They seem to have
very good manners. Do they never speak?"

"They lack the gift," said the philosopher.

"Yet I think I hear them sing," said the other.

"That is only the wind among the leaves," said the philosopher. "I
will explain to you the theory of winds: it is very interesting."

"Well," said the stranger, "I wish I knew what they are thinking."

"They cannot think," said the philosopher.

"I don't know about that," returned the stranger: and then, laying
his hand upon a trunk: "I like these people," said he.

"They are not people at all," said the philosopher. "Come along."

Next they came through a meadow where there were cows.

"These are very dirty people," said the stranger.

"They are not people at all," said the philosopher; and he
explained what a cow is in scientific words which I have forgotten.
