Then she told him how to hold his racket for certain plays, and instructed him in the theory of the angles of incidence and refraction upon which both tennis and billiards are founded.

“Yes!” he would say, and “Really, now!”; or “Why, we learned all that in physics, but I never saw any use for it!” But his main interest was in watching the bright, eager face, the frank, brown eyes which looked straight into him steadily and explored him; and without the slightest gleam of—well, there is no word for it—the sort of mature awareness that is rarely absent when a woman looks steadily into the eyes of a man. There was health in her face and a dominant egoism like a man’s. The last time he had talked with her she had been timid, and clinging, and feminine; a thing that had frightened him off. He remembered that he had likened her to a young aunt—visited rarely—who used to throw her arms about him without notice and kiss him back of the ear. After much practice he had learned finally to sense the beginning of the aunt’s attack and so, in a measure, defend himself. A pathetic lookup of the eyes, dog-like and reverent, was the unfailing sign; just so, at their last meeting, this Levering lady had regarded him as they walked together. Unconsciously he had kept one arm ready to ward off a possible pounce.

Miss Levering had not the shadow of a pounce about her now. She was talking tennis like a sporting editor. Somehow, the professor felt sorry. His strongest wish at that moment was to be attacked.

And he wasn’t listening at all to her harangue.

“You must watch the other fellow’s swing. If he ‘cuts’ up you mustn’t ‘cut’ down. The ball is turning round and round, this way,” she illustrated by swinging circles. “If you spin it the way it’s going it will drop dead.”

The professor was watching her animated face with the most open delight; and he followed her minute instructions absolutely not at all. Simple admiration beamed from him.

“My dear young lady! My dear young lady!” he was saying over and over to himself. “I will never call you ‘Keyser.’ It is the name of an emperor and a dog, but not of a bit of humanity like your delightful self. Wonder of wonders! Cosmos and chaos! Who can understand, O Lord, thy marvelous doings.... Male and female created He them.... Eyes, smiles, voice, gestures inimitable; soul, being, essence—what are they?... I don’t know anything.... Saw her for hours at a time and never noticed her till now.... Could we live on $600 salary and the rent of six small dwellings, not always rented, and the income of the D. & W. R. R., if it ever pays dividends? Glory be to Peter, what are eyes made of? And flesh and blood? Marvelous!... The Lord have mercy upon us and incline our hearts to keep Thy law!... Talk on!... I’m not listening! It’s great! Oh, what a wonderful—”

Then he spoke aloud, ejaculating as if he had been stung by a green fly.

“Great Jupiter!” he shouted, and “Bless my soul!”

She had stood to show him how to swing his racket for a “Lawford,” in those days a rare stroke among amateurs.
