FORGIVENESS and garters lose their snap when they are stretched too often. Once before Forbes had apologized to Persis for an excess of enthusiasm, and her forgiveness had brought back her cordiality with perfect elasticity. The second time there had been a slight sag.

The boundary between the impertinence of a cad and the privilege of a suitor is vague and wavering. The act that is accepted as a manifestation of devotion, a pretty caress, from the accepted lover becomes a liberty from the libertine. In his ardor Forbes had overstepped the dead-line.

There was no especial reason why the pressure of foot upon foot should be a less poetic tribute than a lingering clasp of the hands. But thinking makes it so, and when Forbes put his best foot forward, Persis resented it as a familiarity, an affront. It meant in her eyes that he held her cheap and easy. It was like her to be less angry with him than with herself. She reasoned that if a man she had just met could so speedily rate her so low, there must be some appalling fault in her manner. Her self-confidence was shaken.

But just as she had set Forbes in the category of men with whom a woman must be on her guard, he spoke of being jealous of her, and his very eyes and the flush on his cheeks shouted that he meant it.

There is, perhaps, no other tribute a woman prizes so highly as jealousy. Other tokens of esteem may be silver, gilt, or plated ware, but jealousy is the hallmark of sincerity; jealousy is at least eighteen karats fine.

The moment Forbes said he had been jealous, and by his eager questions, by their very insistent impertinence, indeed, proved that he was now jealous, he became important to Persis. The fervor of his previous actions was almost justified. Even the intrusion upon her foot was a different act.

Women usually think that love excuses almost everything, and sanctifies what were else ridiculous or disgusting. They absolve the sinner who can plead, "I was in love," more easily than the self-righteous abstainer.

Besides, there was something uncanny to Persis in Forbes' statement that he had followed her up the Avenue, and had felt a jealousy of her haste; because that had been a momentous day altogether.

She had begun it by a shopping raid. She had run across a flock of new hats, curious oddities from Paris, perched like strange birds alighted in a window. They pulled down so far on one side that they blinded one eye of the wearer, and they thrust out so far to the rear and the side that they blinded the passer-by.

As she was trying one of them on, she turned her head to speak to the rhapsodical manager. She swept the face of the saleswoman till she sneezed; and when Persis turned to apologize to the saleswoman, the manager found himself inhaling exotic goura. It was fascinating. She simply must have some of these hats.

But there had been a very polite note with her last bill, a timid plea that she pay a trifle on the venerable debt. She hardly dared increase the sum instead of diminishing it. She decided to ask her father's help. The price was beyond her own private bank-account, which was usually chaotically overdrawn, and which the bank carried along with an amused patience, because her father was one of its oldest customers.

Determined to have those hats that day or die, Persis had ridden all the way to her father's office in Broad Street to ask him to buy them. She had found him in great distress. Before she could explain her errand, he had said, with a smile that was pitifully brave:

"I needn't ask what evil motive brings you down here. It was just to tell your old father how much you love him."

"Yes, of course; you know how I worship you." She sat on the arm of his chair with a smile as alluring as a mining-stock prospectus. "Also, I thought you'd like to know that I've struck the most wonderful hats ever imported. They're marked down to almost nothing, and they're really an amazing bargain—especially when you deduct the cost of an ocean voyage, for I couldn't equal them this side of Paris."

He shook his head with a helpless finality that gave her pause. This terrified her. He had refused her something! She knew that the only things that would prevent him from giving her money were absence of funds and inability to borrow them. He explained, tenderly:

"I'm in a lot of trouble, honey. I've got to shift some of my loans to other banks, and I've got to borrow a lot more somewhere. And I don't know where. I'm sorry to tell you, but you'd better know."

She soothed him with loving terror. She told him how little she really cared for the hats; she wanted them only because everybody else had them. The hat she had on would do for a while. It had been so far in advance when she bought it that it was quite good style now—not the very latest, of course, but still good enough since he was feeling poor.

He told her that she need not worry; everything would come out all right. He was just a little pinched for the moment. But he kissed her very devoutly, and sighed and told her how beautiful she was and how dear to him.

She returned to her car, and ordered the driver home. It was a long journey up the caÑon of Broadway, a plank road for miles, since a subway was burrowing underneath. She had ample time to figure out just what it meant to her to be poor. They had been pinched before. Her father was the fourth generation of wealth, and the inheritance of financial genius was wearing out in the family.

Cold flashes of fright ran through Persis as the car rumbled and swerved. Then she remembered that Willie Enslee was to call upon her that afternoon. He had said that he had something very important to say, and she had laughed inly, knowing just what he meant. He was so ridiculous in his love. But now she thought of him as a salvation. She resolved to be sensible and cut the silly romance out of her hopes. She could save her father, and have all the hats in the world. She must not keep Willie waiting. He might not wait. It was in this mood that Forbes had first seen her and her old hat from the bus.

At home she had found Willie. As she walked into the drawing-room he was pacing up and down rehearsing his proposal in whispers. He went into a blue funk at the sight of her, and she had the greatest difficulty in coaxing him to propose. Then she accepted him with proper surprise.

Willie had brought the ring—a wonderful composition by RenÉ Lalique. Fashion had changed enough to permit an engagement ring to be something besides a solitaire diamond. This poem in gold had cost him more than Forbes' salary for two years. Persis had worn it when she met Forbes that same night at the theater. She had worn it when she taught him to turkey-trot. It was the edge of that ring that had cut her finger till it bled under the fierce grip of Forbes' hand at the performance of "Tristan and Isolde."

Thoughts like this danced through Persis' mind now, while her body danced in Forbes' arms. And Forbes was talking of his jealousy!

Forbes was different from Willie in so many ways. He could be loved. She did not love him now. But he was of the type that women love. She wondered, rather helplessly, if she were going to love him. She certainly could never love Willie, and no woman wants to die without loving somebody.

She would not be indiscreet, of course, or disloyal in any important way. But—After all, she might not marry Willie. She might marry Mr. Forbes. All things were possible. Why not this? He would be a husband worth having—a soldier, a gentleman, a lover, distinguished—nobody would laugh if she went up the aisle with him.

Luckily Forbes had money. He was surely not so rich as Willie. But then Persis was not mercenary. She wanted only a reasonable amount—just enough to keep up with the procession, have a fresh hat now and then, and some gowns and a contemporary car, and a place in town and a place out of town, and enough to go abroad on every summer, and South every winter, and a few things like that. Surely Mr. Forbes must have enough money for such a simple household.

Of course, she would not marry him, and it might be dangerous to play with fire; but it would be pitiful never to go near the fire. Worse, it would be pusillanimous. Now that she had accepted Willie, it was certain that she was not to have love in her life unless she took it outside.

Not all of this Cubist chaos of meditation went on during the brief remainder of the dance. But it began there, and it was small wonder if the logic had a little rag-time in it; as for instance:

Since Persis and Willie had agreed not to announce their engagement just yet, this justified lying to a lot of people; for one surely had a right to evade a question that nobody had a right to ask. Of course, if Forbes were really in love with Persis he had a right to ask. But if she told him, then he would stop loving her; at least he would stop seeing her. She knew the man. And she didn't want him to stop seeing her. He was really very nice!

He was a box of matches. She would not strike a light. Or perhaps she might strike one; but she would let it burn only a moment, and then blow it out and not light another. Besides, she was not an official fiancee till it was announced. And Mr. Forbes danced so wonderfully—oh, Lord, it was a sad world. Yet it was very comfortable, dancing in this man's arms.

Meanwhile he was pounding at the door of her heart again:

"Are you going to ride in Central Park to-morrow—this morning?" he said.

"Yes."

"Rain or shine?"

"Yes."

"May I ride there, too?"

"It's not my park."

"That's not very encouraging."

"Isn't it? Well, haven't you been a trifle discouraging yourself?"

"I'm terribly sorry," he pleaded; and she surprised him by sighing:

"I'm rather glad."

"Glad? Why?"

"Because I had come dangerously near to feeling that you were—different."

"I am," he cried, stung by the deep significance of her light regret. "Please let me prove it. Please let me ride with you in the park?"

"I'll be with my father, you know," she answered, with a trace of relentment. "It's my only chance to visit with the poor old boy. You'd better not."

"But some day you will ride with me?"

"Maybe."

"To-morrow may I stand on the bridge and watch you go by?"

"The park is open to the public at all hours."

"Would you mind if I got a horse and rode by and said 'Good morning!'"

"Fine. Come along. I'll introduce you to my father."

"I'll be there!"
