"At first," repeated the doctor. "Well, Daisy, I suppose it was no more. But there is something else growing there, which you have not spoken of."
"Is there?" said Daisy. "I do not see anything else."
"Pardon me you do see it."
"Then I do not know what it is," said Daisy, laughing. Absolutely, the sober, sober little face had forgotten its care, and the eyes were alight with intelligence and curiosity, and the lips were unbent in good honest laughter. The doctor raised himself up to a sitting posture.
"What do you call those grey and brown patches of colour that hide your rock all over?"
"Grey and brown?" said Daisy, wistfully "those are just the colours of the rock, aren't they?"
"No. Look close.
"Why, Dr. Sandford, what is it? It is not the rock some of it is not but here is a spot of yellow that is nothing else, I think."
"You must learn not to trust your eyes, Daisy. That is something that grows; it is not rock; it is a vegetable. If I had my pocket lens here I would show you; but I am afraid yes, I have left it at home."
"Why, it is!" cried Daisy. "I can see now it is not rock.
What is it, Dr. Sandford?"
