"Sami doesn't need to see a stranger."

"Well, that's primitive enough, surely! Let's call him in."

"I'd like to, but Sami won't come for calling."

"Oh, won't he? Leave the door open and watch him."

As absorbed now as the girl herself, the professor put his finger to his lips and whistled—a low, clear whistle, rather like the calling of a meditative bird. Several times he whistled so, on different notes; and then, to her surprise, the watching girl saw the little wild thing outside stir in answer to the call. Sami came out from behind the post and stood listening, for all the world like an inquiring squirrel. The whistle sounded again, a plaintive, seeking sound, infinitely alluring. It seemed to draw the heart like a living thing. Slowly at first and then with the swift, gliding motion of the woods, the wide-eyed youngster approached the open door and stood there waiting, poised and ready for advance or flight. Again the whistle came, and to it came Sami, straight as a bird to its calling mate.

"Tamed!" said the professor softly. "See, he is not a bit afraid."

"How on earth did you do it?" asked Miss Farr when the shy, brown baby had been duly welcomed. The whistler was visibly vain.

"Oh, it's quite simple. I merely talked to him in his own language."

"I see that. But where did you learn the language?"

"Well, a fellow taught me that—man I met at Ypres. He could have whistled back the dodo, I think. He knew all kinds of calls—said all the wild things answered to them."

"Was he a great naturalist?"

The cheerful vanity faded from Spence's face, leaving it sombre.

"He—would have been," he said briefly.

Miss Farr asked no more questions. It was a restful way she had. And perhaps because she did not ask, the professor felt an unaccustomed impulse. "He was a wonderful chap," he volunteered. "There are few like him in a generation. It seemed—rather a waste."

The girl nodded. "Used or wasted—it's as it happens," she said. "There is no plan."

"That's a heathen sentiment!" The professor recovered his cheerfulness. "A sentiment not at all suited for the contemplation of extreme youth."

"I am not extremely young."

"You? I was referring to our brown brother. He is becoming uneasy again. What's the matter with him?"

Whatever was the matter, it reached, at that moment, an acute stage and Sami disappeared through the door into the kitchen. Perhaps his ears were sharper than theirs and his eyes keener. He may have seen a large umbrella coming across the clearing.

Miss Farr frowned. "Sami is afraid of father," she explained briefly. The door opened as she added, "I wonder why?"

"A caprice of childhood, my daughter," said the old doctor mildly. "Who indeed can account for the vagaries of the young?"

"They are usually quite easy to account for," replied his daughter coldly. "You must have frightened the child some time."

"Tut, tut, my dear. How could an old fogey like myself frighten anyone?"

"I don't know. But I should like to."

Father and daughter looked at each other for a moment. And again the captive on the sofa found himself disliking intensely the glance of the old man's pale blue eyes. He was glad to see that they fell before the grey eyes of the girl.

"Well, well!" murmured Dr. Farr vaguely, looking away. "It doesn't matter. It doesn't matter. Tut, tut, a trifle!"

"I don't think so," said she. And abruptly she went out after the child.

"Fanciful, very fanciful," murmured the old man, looking after her. "And stubborn, very stubborn. A bad fault in one so young. But," beaming benevolently upon his guest, "we must not trouble you with our small domestic discords. You are much better, I see, much better. That is good."

"Getting along very nicely, thanks," said Spence. "I was able to change position this morning without assistance."

"Only that?" The doctor's disappointment was patent. "Come, we should progress better than that. If you will allow me to prescribe—"

"Thank you—no. I feel quite satisfied with the treatment prescribed by old Bones—I mean by my friend, Dr. Rogers. He understands the case thoroughly. One must be patient."

"Quite so, quite so." The curiously blurred face of the doctor seemed for a moment to take on sharper lines. Spence had observed it do this before under stress of feeling. But as the exact feeling which caused the change was usually obscure, it seemed safest to ignore it altogether. He was growing quite expert at ignoring things. For, quite contrary to the usual trend of his character, he was reacting to the urge of a growing desire to stay where he wasn't wanted. He didn't reason about it. He did not even admit it. But it moved in his mind.

"I'm not fretting at all about being tied up here," he went on cheerfully. "I find the air quite stimulating. I believe I could work here. In fact, I have some notes with me which I may elaborate. I fancy that, as you said in your letters, Miss Farr will prove a most capable secretary. I am going to ask her to help me."

"Are you indeed?" The doctor's tone was polite but absent.

"You do not object, I hope?"

"Object—why should I object? But Desire is busy, very busy. I doubt if her duties will spare her. I doubt it very much."

"Naturally, I should wish to offer her ample remuneration."

Again the loose lines of the strange old face seemed to sharpen. There was a growing eagerness in the pale eyes ... but it died.

"Even in that case," said Dr. Farr regretfully, "I fear it will be impossible."

Spence pressed this particular point no further. He had found out what he wanted to know, namely, that his host's desire to see the last of him was stronger even than his desire for money. His own desire to see more of his host strengthened in proportion.

"Supposing we leave it to Miss Farr herself," he suggested smoothly. "Since you have personally no objection. If she is unwilling to oblige me, of course—"

"I will speak to her," promised the doctor.

Spence smiled.

"What surprises me, doctor," he went on, pushing a little further, "is how you have managed to keep so very intelligent a secretary in so restricted an environment. The stronger one's wings, the stronger the temptation to use them."

He had expected to strike fire with this, but the pale eyes looked placidly past him.

"Desire has left me, at times, but—she has always come back." The old man's voice was very gentle, almost caressing, and should certainly have provided no reason for the chill that crept up his hearer's spine.

"She has never found work suited to her, perhaps," suggested Spence. "If you will allow me,—"

"You are very kind," the velvet was off the doctor's voice now. He rose with a certain travesty of dignity. "But I may say that I desire—that I will tolerate—no interference. My daughter's future shall be her father's care."

Spence laughed. It was an insulting laugh, and he knew it. But the contrast between the grandiloquent words and the ridiculous figure which uttered them was too much for him. Besides, though the most courteous of men, he deliberately wished to be insulting. He couldn't help it. There rose up in him, suddenly, a wild and unreasoning anger that mere paternity could place anyone (and especially a young girl with cool, grey eyes) in the power of such a caricature of manhood.

"Really?" said Spence. There was everything in the word that tone could utter of challenge and derision. He raised himself upon his elbow. The doctor, who had been closely contemplating his umbrella, looked up slowly. The eyes of the two men met.... Spence had never seen eyes like that ... they dazzled him like sudden sunlight on a blade of steel ... they clung to his mind and bewildered it ... he forgot the question at issue ... he forgot—

Just then Li Ho opened the kitchen door.

"Get 'um lunch now," said Li Ho, in his toneless drawl. "Like 'um egg flied?
