again, shrinking back against the wall.
"They—they—it's—" Mercer's whispered words died away. We were both terrified beyond the power of reasoning. The dragging footsteps came closer—a sound that had in it nothing of human tread. Then we heard soft voices—words that were unintelligible.
"It's the Mercutians," I found voice to whisper. "They—"
A figure appeared in the porch doorway, outlined against the light behind—the figure of a short, squat man. He seemed to have on some sort of white, furry garment. He was bareheaded, with hair falling to his shoulders.
At the sight of him my terror suddenly left me. Here was an enemy I could cope with. The dread fear of supernatural beings that had possessed me evaporated.
With a shout to Mercer I dashed forward directly at the doorway. I think the Mercutian had not yet seen us; he stood quite still, his body blocking the full width of the doorway.
I let fly with my fist as I came up and hit him full in the face. At the same instant my body struck his. He toppled backward and I went through the doorway. I tripped over him on the porch outside and fell sprawling. Before I could rise three other Mercutians fell upon me and pinned me down.
Mercer was right behind me in the doorway. I saw him pause an instant to see what was happening. There seemed to be five Mercutians altogether. The one I had hit lay quite still. Three others were holding me.
The fifth stood to one side, watching Mercer, but apparently inactive.
I saw Mercer hesitate. An expression of surprise came over his face. His body swayed; he took a single step forward, half turned, and then fell in a crumpled heap.
CHAPTER VI.
MIELA.
The girl stood quiet beside the tree, watching Alan as he tied up his boat. She continued smiling. Alan stood up and faced her. He wondered what he should say—whether she could understand him any better than he could her.
"You speak English?" he began hesitantly.
The girl did not answer at once; she seemed to be trying to divine his meaning. Then she waved her hand—a curious movement, which he took to be a gesture of negation—her broadening smile disclosing teeth that were small, even, and very white.
At this closer view Alan could see she was apparently about twenty years old, as time is reckoned on earth. Her body was very slender, gracefully rounded, yet with an appearance of extreme fragility. Her slenderness, and the long, sleek wings behind, made her appear taller than she really was; actually she was about the height of a normal woman of our own race.
Her legs were covered by a pair of trousers of some silky fabric, grayish blue in color. Her bare feet were incased in sandals, the golden cords of which crossed her insteps and wound about her ankles, fastening down the lower hems of the trousers. A silken, gray‑blue scarf was wound about her waist; crossing in front, it passed up over her breast and shoulders, crossing again between the wings behind and descending to the waist.
Her hair was a smooth, glossy black. It was parted in the middle, covered her ears, and came forward over each shoulder. The plaits were bound tightly around with silken cords; each was fastened to her body in two places, at the waist and, where the plait ended, the outside of the trouser leg just above the knee.
Her skin was cream colored, smooth in texture, and with a delicate flush of red beneath the surface. Her eyes were black, her face small and oval, with a delicately pointed chin. There was nothing remarkable about her features except that they were extraordinarily beautiful. But—and this point Alan noticed at once—there was in her expression, in the delicacy of her face, a spiritual look that he had never seen in a woman before. It made him trust her; and—even then, I think—love her, too.
Such was the strange girl as Alan saw her that morning standing beside the tree on the bank of the little Florida bayou.
"I can't talk your language," said Alan. He realized it was a silly thing to say. But his smile answered hers, and he went forward until he was standing close beside her. She did not appear so tall now, for he towered over her, the strength and bigness of his frame making hers seem all the frailer by contrast.
He held out his hand. The girl looked at it, puzzled.
"Won't you shake hands?" he said; and then he realized that, too, was a silly remark.
She wrinkled up her forehead in thought; then, with a sudden comprehension, she laughed—a soft little ripple of laughter—and placed her hand awkwardly in his.
As he released her hand she reached hers forward and brushed it lightly against his cheek. Alan understood that was her form of greeting. Then she spread her wings and curtsied low—making as charming a picture, he thought, as he had ever seen in his life.
As she straightened up her eyes laughed into his, and again she spoke a few soft words—wholly unintelligible. Then she pointed toward the sun, which was still low over the horizon, and then to the silver object lying back near the center of the island.
"I know," said Alan. "Mercury."
The girl repeated his last word immediately, enunciating it almost perfectly. Then she laid her hand upon her breast, saying: "Miela."
"Alan," he answered, indicating himself.
The girl laughed delightedly, repeating the word several times. Then she took him by the hand and made him understand that she wished to lead him back into the island.
They started off, and then Alan noticed a curious thing. She walked as though weighted to the ground by some invisible load. She did not raise her feet normally, but dragged them, like a diver who walks on land in his heavily weighted iron shoes. After a few steps she spread her wings, and, flapping them slowly, was able to get along better, although it was obvious that she could not lift her body off the ground to fly.
For a moment Alan was puzzled, then he understood. The force of gravity on earth was too great for the power of her muscles, which were developed only to meet the pull of Mercury—a very much smaller planet.
The girl was so exceedingly frail Alan judged she did not weigh, here on earth, much over a hundred pounds. But even that he could see was too much for her. She could not fly, and it was only by the aid of her wings that she was able to walk with anything like his own freedom of movement.
He made her understand, somehow, that he comprehended her plight. Then, after a time, he put his left arm about her waist. She spread the great red wings out behind him, the right one passing over his shoulder; and in this fashion they went forward more easily.
The girl kept constantly talking and gesturing. She seemed remarkably intelligent; and even then, at the very beginning of their acquaintanceship, she made Alan understand that she intended to learn his language. Indeed, she seemed concerned about little else; and she went about her task systematically and with an ability that amazed him.
As they walked forward she kept continually stooping to touch objects on the ground—a stick, a handful of sand, a woodland flower, or a palmetto leaf. Or, again, she would indicate articles of his clothing, or his features. In each case Alan gave her the English word; and in each case she repeated it after him.
Once she stopped stock still, and with astonishing rapidity and accuracy rattled off the whole list—some fifteen or twenty words altogether—pointing out each object as she enunciated the word.
Alan understood then—and he found out afterward it was the case—that the girl's memory was extraordinarily retentive, far more retentive than is the case with any normal earth person. He discovered also, a little later, that her intuitive sense was highly developed. She seemed, in many instances, to divine his meaning, quite apart from his words or the gestures—which often
