"I suppose so."
Daisy stood looking with a countenance of delighted intelligence at the great boulder, which was now to her a representative and witness of natural processes she had had no knowledge of before. The mosses, the brakes, the lichen, had all gained new beauty and interest in her eyes. The doctor watched her, and then scrambled up to his feet and came to her side.
"Look here, Daisy," said he, stooping down at the foot of the rock, and showing her where tufts of a delicate little green plant clustered, bearing little umbrella-like heads on tiny shafts of handles.
"What is that, Dr. Sandford?"
"Something wonderful."
"Is it? It is pretty. What is it, sir?"
"It is a plant somewhere between the mosses and the lichens in its character it is one of the liverworts, and they are some of the first plants to go in advance of superior vegetation. This is called Marchantia."
"And is it wonderful, Dr. Sandford?"
"If I could show it to you, you would think so. Look here, Daisy on the surface of this leaf do you see little raised spots here and there?"
"Yes, I see them."
