"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 pa.s.sing 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 were unintelligible to her--with which he accompanied them.

After a time they reached the Mercutian vehicle. It was a cubical box, with a pyramid-shaped top, some thirty feet square at the base, and evidently constructed of metal, a gleaming white nearer like silver than anything else Alan could think of. He saw that it had a door on the side facing him, and several little slitlike windows, covered by a thick, transparent substance which might have been gla.s.s.

As they got up close to it Alan expected the girl's companions to come out. His heart beat faster. Suddenly he raised his voice and shouted: "h.e.l.lo, inside!"

The girl looked startled. Then she smiled and made the negative gesture with her hand.

Alan understood then that she was alone. They went inside the vehicle. It was dark in there. Alan could make out little, but after a moment his eyes grew accustomed to the darkness.

He noticed first that the thing was very solidly constructed. He expected to see some complicated mechanism, but there was little or nothing of the kind so far as he could make out in the darkness in this first hurried inspection.

Fastened to one wall was an apparatus which he judged was for the making of oxygen. He looked around for batteries, and for electric lights, but could see nothing of the kind.

All this time Alan's mind had been busily trying to puzzle out the mystery of the girl's presence here alone. Evidently she came in the most friendly spirit; and thus, quite evidently, her mission, whatever it was, must be very different from that of the invaders who had landed almost simultaneously in Wyoming.

Whatever it was that had brought her--whatever her purpose--he realized it must be important. The girl, even now, seemed making no effort to show or explain anything to him, but continued plying him with questions that gave her the English words of everything about them that she could readily indicate.

Alan knew then that she must have something important to communicate--something that she wanted to say as quickly as possible. And he knew that she realized the only way was for her to learn his language, which she was doing with the least possible loss of time, and with an utter disregard of everything else that might have obtruded.

Alan decided then to take the girl back home with him--indeed, it had never been in his mind to do anything else--and let Beth care for her.

Meanwhile he would do everything he could to help her get the knowledge necessary to make known what it was that had brought her from Mercury.

That she had some direct connection with the Wyoming invaders he did not doubt.

Alan had just reached this decision when the girl made him realize that she had the same thought in mind. She pointed around the room and then to herself, and he knew that she was insisting upon a general word to include all her surroundings.

Finally Alan answered: "House."

After pointing to him, she waved her hand vaguely toward the country outside the open doorway, and he understood she was asking where his house was.

Alan's decision was given promptly. "We'll go there," he said.

He put his arm about her and started out. By the way she immediately responded he knew she understood, and that it was what she wished to do.

They got back to Alan's launch in a few moments. He seated her in the stern of the boat, where she half reclined with her wings spread out a little behind her. So a.s.siduous was she--and so facile--in her task of learning English, that before she would let him start the motor she had learned the names of many of the new objects in sight, and several verbs connected with his actions of the moment.

There was a large tarpaulin in the launch, and this Alan wrapped about the girl's shoulders. He did not want her vivid red wings to be seen by any one as they pa.s.sed down the bayou.

Finally they started off.

Professor Newland's home was some three miles from the village of Bay Head, on the sh.o.r.e of a large bay which opened into the Gulf of Mexico.

The bayou down which they were heading flowed into this bay near where the house stood. Their home was quite isolated, Alan thought with satisfaction. There was no other habitation nearer than Bay Head except a few negro shacks. With the girl's wings covered he could take her home and keep her there, in absolute seclusion, without causing any comment that might complicate things.

On the way down the bayou the girl showed extreme interest in everything about her. She seemed to have no fear, trusting Alan implicitly in his guidance and protection of her in this strange world. She continued her questions; she laughed frequently, with almost a childlike freedom from care. Only once or twice, he noticed, as some thought occurred to her, the laughter died away, her face suddenly sobered, and a far-away, misty look came into her beautiful eyes.

Alan sat close beside her in the stern, steering the launch and occasionally pulling the tarpaulin back onto her shoulders when it threatened to slip off because of her impetuous gestures.

They saw only a few negroes as they pa.s.sed down the bayou, and these paid no particular attention to them. Within an hour Alan had the girl safely inside the bungalow, and was introducing her, with excited explanations, to his astonished father and sister, who were just at that moment sitting down to breakfast.

CHAPTER VII.

THE MERCUTIAN CAMP.

As I saw Mercer fall to the floor of the porch a sudden rage swept over me. I struggled violently with the three men pinning me down. They appeared very much weaker than I, but even though I could break their holds the three of them were more than a match for me.

The man who was standing inactive, and who I realized had struck down Mercer in some unknown, deadly way, appeared to be the leader. Once, as one of my a.s.sailants made some move, the import of which the leader evidently understood, but which I did not, I heard him give a sharp command. It occurred to me then that if I offered too much resistance--if it seemed I was likely to get away from them--I might possibly be struck as swiftly as Mercer had been. So I gave up abruptly and lay still.

They must have understood my motive--or perhaps they felt that I was not worth the trouble of taking alive--for immediately I stopped struggling they unhanded me and rose to their feet.

I stood up also, deciding to appear quite docile, for the time being at any rate, until I could comprehend better with what I had to contend.
