"What do you say to a long expedition, Daisy?"

"I don't feel like driving, Captain Drummond."

"No, but suppose I drive, and we will leave Loupe at home for to-day. I want to go as far as Schroeder's Hill, to look after trilobites; and I do not want anybody with me but you. Shall we go?"

"What are those things, Captain Drummond?"

"Trilobites?"

"Yes. What are they?"

"Curious things, Daisy! They are a kind of fish that are found on land."

"Fish on land! But then they can't be fish, Captain Drummond?"

"Suppose we go and see," said the captain; "and then, if we find any, we shall know more about them than we do now."

"But how do you catch them?"
