"Quite right."

Hayden regarded his calendar approvingly. The large red and gold letters stared at him proclaiming arrogantly: "Every day is the best day of the year." And was it not true? Yesterday had proved indeed a day of destiny. It had brought him the assurance of a hope, the confirmation of a hesitant belief that the owners of the lost Mariposa were within reach and, better still, were not entirely masters of the situation. And yesterday, too, he had met Ydo; and, perhaps, Hayden's thoughts had been as much occupied with her as with his discovered but not possessed Eldorado.

But Ydo herself was a sufficient excuse for that. And this was another day. A daring thought came to him. Why not assist Fate and make it the best day in the year—a day that should be Marcia's. At this brilliant idea he looked at his watch and then rushed to the telephone. Surely Marcia, even conscientious Marcia who worked painstakingly at her pretty Little water-colors every day, would not have left for her studio. He would throw dice with Destiny again to-day and push his luck. With this determination, he rang up the residence of Mrs. Oldham. There was a moment or two of delay, and then Marcia's voice answered. Hayden mentioned the beauty of the day—it was overcast—the charm of this soft and mild weather—an east wind blew piercingly—and diffidently assumed that after a day in her studio, she would as usual take the air by walking home through the Park.

Yes-s-s-s, she probably would.

Then since he had hoped to call upon her mother that afternoon, might he not join her and walk up with her, and would she not be leaving her brushes and canvases early, at half-after four, for instance.

Yes-s-s, he said four o'clock, did he not? Fate again honored him, she would be at the Plaza then calling on a friend.

Hayden had won in his dice-throwing and Fate took defeat handsomely, granting him his desires and throwing a favor or two for lagnappe. By four o'clock the wind had veered, the clouds no longer betokened rain, broken spars of sunshine dazzled over the gold of the Sherman statue, sparkled in the harness of prancing horses, and brightened the whiteness of the great hotel. It was early in March, which, by the way, had decided to enter like a meek little lamb this year instead of advancing with the mien of an angry and roaring lion. The air was cool and fresh and yet held all manner of soft, indescribable intimations of spring. The sky was a sheet of pale gold, the trees were a purple mist against it.

Hayden drew a long breath of happiness as Marcia's steps fell in with his; the sense of contentment and well-being which her mere presence always afforded him seemed the more soothing and potent this afternoon than ever before. Since yesterday, there had run high in his veins the fever of acquisition, and Ydo's personality had disturbed and stimulated until she had wrought in him a sort of mental confusion. But Marcia at his side, smiling in the shadow of her plumed hat, the familiar violets nestling in her dark furs, seemed the visible embodiment of all these soft, sweet intimations of spring. Not yet jocund, as spring come into her own crowned with flowers and laughing through her silver rain; but a wistful spring still held in the thraldom of winter.

"What have you been doing that makes you look a little pale?" asked Hayden tenderly.

"Am I pale?" She smiled at him. "I dare say. I have been painting the greater part of every day and going out a good deal in the evening."

"What an idler I must seem to you who are always so occupied," he said.

"Not at all. I, too, take vacations. But tell me how you have been idling lately."

"I idled, if you call it that," he said, "yesterday afternoon at the wonderful fortune-teller's."

"Oh, you have seen Ydo?" Marcia lifted her head involuntarily, and then meeting his surprised gaze, the color flooded her cheeks. It kept on rolling up in waves.

Seeing her embarrassment, he was at pains to suppress his astonishment.

"Yes," he said as naturally as he possibly could under the circumstances. "Yes, she gave me quite a long reading. Isn't that the professional word for it—reading?"

"I—I believe so." She had not entirely recovered herself. "And are you quite convinced of her powers?"

He gave a short laugh. "Oh, quite. More than convinced. I never should question them. Mine is the fate of the scoffer. The most rabid persecutor is merely the reverse side of the bigoted proselyter. Upon me rests not the curse that follows the tolerant. They get nowhere. 'Because thou art neither hot nor cold I spew thee from my mouth.'"

"Really!" It was plain she was a little puzzled, and took refuge in the conveniently inexpressive "really." "Did she tell you a good fortune?"

"How can I say? Fortune is always in the future."

"You are teasing me and telling me nothing," she declared, "and you are laughing, laughing, too, as if over some secret and mysterious joke."

"I am laughing," he said, suddenly serious, "but not over any of the revelations of Mademoiselle Mariposa, I can assure you; and to show you my faith in her prophecies, I am going to tell you something." He was grave enough now. "And yet, I wonder—perhaps—"

"Perhaps what?"

"Perhaps you will find no interest in what I want to say."

She looked up at him quickly, surprise in her glance. "How absurd! I do not see why you say such things. Why should you fancy that I would not be interested in anything you have to tell me?"

They had turned down a narrow lane of trees, and the skies, a deeper and more luminous gold, were in a net of bare, black twigs. The wind bore the fragrance of Marcia's violets past Hayden's nostrils.

"But you may not feel so when I tell you that I love you, Marcia." His voice low and unsteady thrilled her heart. "I realize the rashness of the whole thing; but I do love you, Marcia."

There was a moment's silence, a silence when Hayden's heart-beats sounded louder than the patter of their feet on the concrete pavement or the distant and mighty roar of the city—and then Marcia lifted her eyes to his.

In a moment the miracle had happened. Above them stretched the same gold sky in its intricate and broken nets, the wind blew softly; but they two had stepped across the boundaries of commonplace days straight into Arcady. Flowers bloomed, birds sang, and the soul of the spring was in their hearts. But, curiously enough, though they were in Arcady, they were also in the Park. Hayden looked up the little lane; north and south marched an unending line of people. They were in Arcady, but deprived of its ancient privilege of sylvan and umbrageous solitude.

She was the first to speak. "Why is it absurd?" And her clear voice trembled a little.

"How can it be, as things stand, anything but absurd?" he answered bitterly. "I am simply an engineer on my vacation, who when that is over will return to the wilds. Oh, Marcia, how can I in common decency ask you to marry me? I can not yet, but I do ask you to let me love you, to forgive me for telling you of my feeling for you, and believe me when I tell you that I would not have had the courage to mention the subject if I did not feel almost sure of a change of fortune. I don't want to tell you just yet. I'm trying not to tell you; but dearest, loveliest Marcia, I believe I'm on the eve of success. I can almost close my fingers around it, and then you will let me tell you I love you, won't you, dearest? Yes, laugh at me, I don't mind."

"But suppose, just suppose this wonderful fortune never does materialize," she said half-teasingly but still tremulously, a smile on her lips and a tear in her eye. "What then?"

"Never suppose it. It can't help it," he cried confidently. "Why even now I can see particles of gold in the air. To-morrow, next day, the day afterward, we shall have our cake. Will you eat it with me, Marcia, if it's a nice, brown, plum-y cake?"

"You make too many conditions," she said demurely. "I don't care for very rich cake myself. Suppose the cake should not turn out particularly well in the baking? Wouldn't you offer me a piece anyway—Bobby?"

Again he looked up the path and down the path; people still hastening to and fro. Arcady was infested with toilers hurrying home to supper.

"I'd try not to," he said manfully, keeping his eyes resolutely away from hers. "Oh, Marcia, I can't be certain, I'd try not to. I couldn't bear to see you eating underdone cake. It would only mean misery to you. Your manner of life—"

"My manner of life!" she interrupted him scornfully. "Ah, what is my manner of life! Do you fancy that I am deaf as a post and blind as a bat? Do you think that I do not know some of the things that are spoken of me, by Mrs. Ames, for instance, or Horace Penfield, or even Edith Symmes? Do you fancy any word of that tittle-tattle escapes me? Sometimes it is repeated, or hinted in malice; sometimes as from Bea or Kitty in fright, as a warning, almost a prayer. I know that I lay myself open to gossip; but I can not help it, at least at present. It is impossible for me to alter things just now."

"I know," he murmured tenderly. "I am sure of it. I have realized something of this from the first moment that I met you. But always since that moment I could stake my life on this, that any—any mystery that might seem to exist was not of your making or choosing. And I want to assure you of something, to make you believe it if necessary; and that is, dear, dear Marcia, if you never choose to unravel the tangle I shall still be content."

She looked at him a moment in absolute, speechless wonder, and then tears, happy tears brimmed in her eyes. "Oh, how glad I shall be to unravel it!" She breathed deeply. "How glad! Wait a little—a week, a fortnight. Ah!" She caught herself up hastily. "Come, see how late! It is growing dark and the lights are beginning to twinkle out, and they tell me, even if you will not, that it is time I ran home and got dressed. I'm to dine at Bea Habersham's to-night. You must come in with me when we reach home and let mother give you a cup of tea. You are a tremendous favorite of hers; she says you are wonderfully witty. And then you can drive as far as Bea's with me, and I will have the chauffeur take you on home. Will you?"

"Will I? Will I? Thank you very much, Miss Oldham, for your amiability in Suggesting such a thing; but I could not possibly take advantage of your kindness." If the wit of this sally may be judged by the manner in which it was received Hayden had just uttered one of the great bon-mots of the ages.

"I hope," said Marcia presently, a touch of apprehension in her tone, "that some one has been to see mother this afternoon. Poor dear! She always feels a little aggrieved if no one comes."

"Let us appease any possible disappointment she may have suffered by taking her a present," suggested Hayden, fired by inspiration. "Women, children, every one likes presents, do they not? Come, let us find shops."

"What an adventurer you are!" laughed Marcia, letting him lead her across the street, a confusion crowded with swiftly moving vehicles and cars, for they had now left the twilight shadows and comparative seclusion of the Park and were walking down the noisy thoroughfare.

"You will have to make a quick decision," she added as they came upon a region of many brilliant shops and sidewalks crowded with people. "What will you take her, fruit or flowers?"

But Hayden was too happy to consider any topic with gravity. "We will take her a swanboat, or one of the Hesperidian apples, or the Golden Fleece."

And although Marcia spent herself in urging him to stick to the conservative fruit and flowers, he insisted on following his own vagrant fancy, and at last decided upon an elaborate French basket of pale-blue satin covered with shirrings of fine tulle. The lid was a mass of artificial flowers, violets and delicate pink roses, and within the satin-lined depths was a bunch of Hamburg grapes.

This, when finally and carefully wrapped, made a huge package; but Hayden insisted on carrying it, assuring Marcia that every one they met would be sure that he was carrying home the turkey for their Sunday dinner. He bore it ostentatiously, and took particular glee in any passing attention they excited.

"You act as if you were twenty, instead of well—let me guess your age," looking at him with keen scrutiny. "About thirty-five," said Marcia cruelly.

He stopped short to gaze at her with pained reproach. "I am Youth! Incarnate Youth, just eighteen. No doubt to your dulled materialistic vision I appear to wear a coat and hat. Is that true?" with polite, tolerant patience.

"It certainly appears that way to me," she replied. "What do you imagine yourself to be wearing?"

"And I dare say," he continued still patiently, "that you also fancy you and I are strolling about in one of the shopping districts of New York?"

"Yes," nodding affirmatively. "Where else?"

"Wretched, purblind girl! Thirty-five indeed! Why, I am eighteen, and clad in the hide of a leopard with a wreath of roses on my brow, and you, sweet Œnone, are wandering with me on the slopes of Ida—and we are taking your mother, not one, but a peck of golden apples."

"All things considered," said Marcia significantly, "I am glad we have reached our own door."

They found Mrs. Oldham in good spirits in consequence of having seen a number of people who had sufficient tact duly to admire her new costume worn for the first time that afternoon. She had given much consideration to all the effects of the picture she wished to create, and now sat in an especial chair in an especial part of the room, a vision in pale gray and orchid tints most skilfully mingled. Her feet, in orchid silk stockings, and slippers adorned with great choux of gray chiffon, looked on their footstool as if they were a part of the decorations of the room and had never served the utilitarian purpose of conveyance.

"Oh, I am glad to see you!" she cried, peering past Marcia to Hayden who followed, almost obscured by his great package. She stretched out a hand for him to take, not disarranging her pose by rising and thus spoiling the composition. "Marcia, you're dreadfully late, as usual," a touch of fretfulness in her voice.

"I know," replied her daughter; "and now, I'm going to leave Mr. Hayden to you. Give him some tea, won't you? I'm dining at the Habershams, you know, and he will drive down with me after a while."

"Of course I'll give Mr. Hayden some tea. Send in some hot water, Marcia." She leaned forward, still careful not to move her feet and fussed with the tea things on the table by her side. "I am very glad to see you," she murmured again. "Ah, Mr. Hayden, if it were not for my friends I should be a very lonely woman. You understand, of course, that I do not complain. Marcia is the dearest girl that ever was, so lovely and attractive. Oh, dear, yes. But," with an upward glance of resignation, "quite young people are apt to be thoughtless, you know, and Marcia's social life is so much to her, and indeed, I am selfish enough to be truly glad that it is so; it really is a great bond between dear Wilfred and herself; but of course it leaves me much alone; and it is not good for me to be thrown back on myself and my own sad thoughts so much. Mr. Oldham always recognized that fact. 'Change, constant diversion is an Absolute necessity to one of your sensitive, high-strung nature,' he would so often say, but," with a long-drawn sigh, "no one thinks enough about me to feel that way now."

"Don't say that," said Hayden cheerfully. "I may not be any one, but I've been thinking about you. Look! I carried this enormous bundle through the streets just for you. Be careful. It's heavy."

She flushed with pleasure through her delicately applied rouge, and stretching out her hands for her gift began eagerly to unwind the various tissue-papers which concealed it. The last of these discarded, she placed the basket in the middle of the table and spent herself in ecstatic phrases, melting from pose to pose of graceful admiration.

"Ah, Mr. Hayden," with one of her archest glances, "you remind me so much of Mr. Oldham." Hayden had a swift, mental picture of that grim old pirate of finance, as represented by his portraits and photographs, his shrewd, rugged old face surrounded by Horace Greeley whiskers. "He never came home without bringing me something. Sometimes it was just a flower, or some fruit, and again it was a jewel. You can't fancy, Mr. Hayden, no words of mine can express to you his constant thought and care for me. You take lemon in your tea, do you not? I thought so. I always remember those little things about my friends. And he had such faith in my business judgment, too. He would often discuss business with me and ask my opinion on this or that matter; and he always, without exception, acted on my advice. He used to say—so foolish of him—that he could not understand why he should have been so favored as to have found a combination of beauty and brains in one woman."

"It is rare, but as I understand now, not impossible." Hayden took his cue nobly.

"Oh, Mr. Hayden!" A reproving finger was shaken at him with the archest coquetry. "If you talk that way I shan't give you another cup of tea, no matter how hard you beg. But where was I? Oh, yes, I was telling you that Mr. Oldham so often discussed business matters with me."

"And did they interest you?" asked Hayden vaguely, wondering how soon he could possibly expect Marcia to return.

"Oh, yes, I found it more thrilling than the printed page."

"Most men do," he replied dryly. "I didn't know that women felt that way."

"I did." Mrs. Oldham nodded her head in modest acceptation of the fact that she was the exceptional woman. "I found it not only thrilling, but often so romantic. I do not see why people will speak of 'the dry details of business.' I think it is full of romance."

Hayden stared at her with the amazement her mental processes always aroused in him.

"It never seemed exactly within the range of romantic subjects to me," he said dubiously; "but perhaps that's the way I've been looking at it."

"Certainly it is," she affirmed triumphantly. "Now I'll prove it to you. As I often say to young people, Mr. Hayden: 'Never make an assertion unless you can prove it.' Now, I distinctly remember Mr. Oldham telling me of a most romantic business matter. A lost mine of almost unthinkable value which was on an old estate somewhere in Brazil, or no, Peru. Why, what is the matter, Mr. Hayden? Your eyes are almost popping out of your head. You look as if you had seen a ghost."

Hayden caught himself together. "It is only that it is so interesting. Do go on and let me hear the rest of it."

Mrs. Oldham smiled, well pleased at the tribute to her powers as a raconteuse. "Well, there isn't much to tell. I've forgotten the details, and they were so romantic, too; but Mr. Oldham seriously considered buying it."

"And did he buy it?" Hayden's hands were trembling in spite of himself. "This is so intensely interesting, one would like to hear the conclusion of the story."

But Mrs. Oldham only shook her head. "I don't know," she said vaguely. "I think he did; but I can't be sure."

She began another long story, but Hayden, after listening to enough of it to assure himself that it had no bearing on The Veiled Mariposa, gave himself up to the confused conjectures, the hopes, the dreams that thronged his brain.

Was it a possibility that Marcia, Marcia, might be the heiress of the great Mariposa estate? The owner, or one of the owners of it? He felt overcome by the bare mental suggestion. But was it a possibility, even a dim and remote one? Accepting this as a temporary hypothesis, was it not borne out by certain facts? The butterflies, for instance. Did not those jeweled ornaments symbolize in some delicate, fanciful way, Marcia's way, her ownership of The Veiled Mariposa? And would not that ownership also account for the much-questioned source of her wealth? He stopped with a jerk up against a dead wall. The Mariposa mine had not been worked for years; the ranches were cultivated only by the Spaniard in possession. These facts were like a dash of cold water, extinguishing the flame of his hopes. And yet, and yet, the butterflies! But that, he was forced to admit, might be the merest coincidence.

On that chain of evidence he would find it necessary to regard his cousin, Kitty Hampton, Mrs. Habersham, the London actress, a score of women, as possible owners of his Golconda. Nevertheless, in spite of reason, he could not escape the conviction, unfounded but persistent, that those butterflies were in some way connected with the ownership of that distant lost mine. And this purely intuitive belief was suddenly strengthened by the remembrance of Marcia's embarrassment in the Park, an hour or two before, when she had involuntarily and inadvertently spoken of Mademoiselle Mariposa familiarly as Ydo.

"Yes, Mrs. Oldham, I quite agree with you. As you say: 'One can not be too careful.' Oh, no, I never was more interested in my life."

Ydo! Ydo! He took up the thread of his absorbing reflections again as Mrs. Oldham's voice purled on reciting with infinite detail all the data of one of her Helen-like conquests. Ydo! What bond could exist between the reserved, even haughty Marcia in spite of all her gentleness, and the capricious, wayward, challenging Ydo? A bond sufficiently strong to permit the affectionate familiarity of first names? He had from the beginning believed that Ydo had some interest in the property, although he had never been able satisfactorily to guess the nature of it. But Marcia! The mere possibility of her being interested in what Ydo merrily called his Eldorado had never struck him before, and his brain was bewildered by the thousand new trains of conjecture it started.

At this point his reflections were broken in upon by the entrance of Marcia herself. She was all in white with the big, ruby-eyed butterfly on her bosom, and the chain of butterflies about her throat. She looked more radiant than he had ever seen her as she stood before them drawing on her long gloves. Her eyes, no longer sad with all regret, were like deep blue stars, and her smile was full of a soft and girlish happiness.

"You look very well, Marcia," said her mother critically. "A new gown, of course. How differently they are cutting the skirts!"

"It's a lovely gown," affirmed Hayden, smiling down into Marcia's eyes. "After all, a simple white frock is the prettiest thing a woman can wear."

"Simple!" Mrs. Oldham's mirth was high and satiric. "Isn't that like a man? Simple is the last word to be applied to Marcia's frocks, Mr. Hayden. It's a good thing, as I often tell her, that her father left us so well provided for."

The lovely happiness vanished from Marcia's eyes. She looked quickly at her mother with an almost frightened expression, and then, with eyelashes lowered on her cheek, went silently on drawing on her gloves, two or three tense little lines showing about her mouth.

"I think Miss Oldham is very unkind," said Hayden, with some idea of bridging the situation gracefully, "never to have shown me any of her pictures. She paints, paints all day long, and yet will not give one a glimpse of the results. Kitty Hampton has been promising to show me some of the water-colors she has, but she has not yet done so."

"Have you been talking much to Mr. Hayden of your pictures, Marcia?" asked her mother suavely.

The tone was pleasant, even casual, and yet, Hayden, sensitive, intuitive, had a quick, shocked sense of having blundered egregiously; and worse, he had a further sense of Mrs. Oldham's words being fraught with some ugly and hidden meaning. In her voice there had been manifest an unsuspected quality which had revealed her for the moment as not all frivolous fool or spoiled and empty-headed doll; but a tyrant and oppressor, crueller and more menacing because infinitely weak and unstable.

Marcia did not reply at all to her mother's question, but with her lashes still downcast, continued to button her gloves; and Hayden stood, miserably uncomfortable for a moment, and then was forced to doubt the correctness of his swift, unpleasant impression; for Mrs. Oldham observed in her usual petulant, inconsequent tones:

"I don't know that I like that necklace with that frock, Marcia. Your turquoises would look better. I do get so tired of always seeing you with some kind of a butterfly ornament. You never showed the slightest interest in butterflies before your father died, and you don't, in the least, suggest a butterfly. I can not understand it."

"Don't try, mother dear," said Marcia. "Good-by." She kissed the orchid and gray lady lightly on the top of the head. "Have a good time with your Hamburg grapes and your last new novel."

She slipped her arms through the long white coat Hayden held for her and, followed by him, left the room.

"Marcia, dear, sweet Marcia," he coaxed, as they whirled through the streets in her electric brougham. "I'm sure, almost dead sure, it's going to be a nice, well-baked, plum-y cake. If it is won't you promise to eat it with me? You know you didn't definitely promise this afternoon, and I never could stand uncertainty."

"No," she said positively, drawing her hand away from his, "I will not. I will never give you a definite answer until you offer me a share in the cake, no matter how it turns out in the baking."

"How can I?" he groaned. "You do not know what sort of a life it would be, the hardships, the deprivations, the necessarily long separations when I would have to be in some place utterly impossible for you, for months at a time. It's the very abomination of desolation. And fancy your trying to adapt yourself to it! You, used to this!" rapping the electric. "And this, and this!" touching lightly the ermine on her cloak and the jewels at her throat. "No." He shook his head doggedly. "I won't. I know what it means and you do not. Lovely butterfly"—the tenderness of his voice stirred her heart-strings—"do you think that I could bear to see you beaten to earth, your bright wings torn and faded by the cruel storms? Never. But," with one of his quick, mercurial changes of mood, "it's an alternative that we do not have to face. For it's coming out all right in the baking—that cake. The most beautiful cake you ever saw, Marcia, with a rich, brown crust, and more plums than you ever dreamed of in a cake before."
