"Are you sure?"

"As certain as that I live."

"Sure—certain! Of what are we sure but the present moment? Into it we ought to crowd all the joys of existence."

Her feminine instinct discovered the return of his thoughts into the old dangerous channel, and her quick wit diverted them.

"Tell me more about your home, and how you felt when you used to sit like this and think."

He determined to yield himself for a little while longer to her will, and said: "In those days Nature possessed for me an irresistible fascination; but the spell is broken now. I then thought that I was face to face with the eternal spirit of the universe. How far I have drifted away from the world in which I then existed! I could never return to it. I am like a bird which has broken its shell and which can never be put back again. I have found another face into which I now look with still deeper wonder than into that of Nature, and which exerts a still deeper fascination. It is the face of a woman, in whom all the beauties of nature seem to be mirrored. She is everything to me; she is the entire universe embodied in a gentle heart."

He gazed at her with a look that made her pulses beat; but she was determined not to permit him to drift back into that dangerous mood from which she had drawn him with such difficulty.

"One time you told me," she said, "that the birds and squirrels were such good friends to you, that if you called them they would come to you like your dog. I should love to see that. Look! There is a squirrel sitting on the limb of this very tree! How saucy he looks! How shy! Bring him to me! I command you! You have said that I am your mistress; go, slave!"

Rising to her feet she pointed to the squirrel. Her lithe form was outlined against the green background of the forest in a pose of exquisite grace and beauty, her eyes glowed with animation, and her lips smiled with the consciousness of power. It was impossible to resist her.

He rose, looked in the direction toward which she pointed, and saw the squirrel cheeping among the branches. Imitating its cries, he began to move slowly toward it. The little creature pricked up its ears, cocked its head on one side, flirted its bushy tail and watched the approaching figure suspiciously. As it drew nearer and nearer, he began to creep down the branches. Stopping now and then to reconnoiter, he started forward again; paused; retreated; returned, and still continued to advance, until he was within a foot or two of David's hand, which he examined first with one eye and then the other and made a motion as if to spring upon it. Suddenly the spell was broken. With a wild flirt of his tail and a loud outcry, he sprang up the tree and disappeared in the foliage.
