the floor, the girl suddenly ran over and stood beside him. Her slim little body came only a little above his shoulder; instinctively he put his arm about her.

      A voice, calling from outside the room, made the girl look up into his face with new terror.

      "Others are coming," she whispered tensely and huddled up against him.

      The Very Young Man saw that the room had two doors—the one through which he had entered, and another in one of its other walls. There were no windows. He pulled the girl now towards the further door, but she held him back.

      "They come that way," she whispered.

      Another voice sounded behind him and the Very Young Man knew that a man was coming up along the passageway from the front entrance. Targo's men! He remembered now the skulking figure he had seen outside the house. There were more than two, for now he heard other voices, and some one calling Targo's name.

      He held the girl closer and stood motionless. Like rats in a trap, he thought. He felt the fingers of his right hand holding something heavy. It was a piece of stone—the stone he had looked at through the microscope—the stone with which he had struck Targo. He smiled to himself, and slipped it into his pocket.

      The girl had slowly pulled him over to the inner wall of the room. The footsteps came closer. They would be here in a moment. The Very Young Man wondered how he should fight them all; then he thought of the knife that was still in the murdered man's body. He thought he ought to get it now while there was still time. He heard a click and the wall against which he and the girl were leaning yielded with their weight. A door swung open—a door the Very Young Man had not seen before. The girl pulled him through the doorway, and swung the door softly closed behind them.

      The Very Young Man found himself now in a long, narrow room with a very high ceiling. It had, apparently, no other door, and no windows. It was evidently a storeroom—piled high with what looked like boxes, and with bales of silks and other fabrics.

      The Very Young Man looked around him hastily. Then he let go of the girl, and, since locks were unknown in this world, began piling as many heavy objects as possible against the door. The girl tried to help him, but he pushed her away. Once he put his ear to the door and listened. He heard voices outside in the strange Oroid tongue.

      The girl stood beside him. "They are lifting Targo up. He speaks; he is not dead," she whispered.

      For several minutes they stood there listening. The voices continued in a low murmur. "They'll know we are in here," said the Very Young Man finally, in an undertone. "Is there any other way out of this room?"

      The girl shook her head. The Very Young Man forgot the import of her answer, and suddenly found himself thinking she was the prettiest girl he had ever seen. She was hardly more than sixteen, with a slender, not yet matured, yet perfectly rounded little body. She wore, like Lylda, a short blue silk tunic, with a golden cord crossing her breast and encircling her waist. Her raven black hair hung in two twisted locks nearly to her knees. Her skin was very white and, even more than Lylda's, gleamed with iridescent color.

      "Only this one door," said the girl. The words brought the Very Young Man to himself with a start.

      No other way out of the room! He knew that Targo and his men would force their way in very soon. He could not prevent them. But it would take time. The Very Young Man remembered that now he had time to take the chemicals. He put his hand to his armpit and felt the pouch that held the drug. He wondered which to take. The ceiling was very high; but to fight in the narrow confines of such a room——

      He led the girl over to a pile of cushions and sat down beside her.

      "Listen," he said briefly. "We are going to take a medicine; it will make us very small. Then we will hide from Targo and his men till they are gone. This is not magic; it is science. Do you understand?"

      "I understand," the girl answered readily. "One of the strangers you are—my brother's friend."

      "You will not be afraid to take the drug?"

      "No." But though she spoke confidently, she drew closer to him and shivered a little.

      The Very Young Man handed her one of the tiny pellets. "Just touch it to the tip of your tongue as I do," he said warningly.

      They took the drug. When it had ceased to act, they found themselves standing on the rough uneven stone surface that was the floor of the room. Far overhead in the dim luminous blackness they could just make out the great arching ceiling, stretching away out of sight down the length of the room. Beside them stood a tremendous shaggy pile of coarsely woven objects that were the silk pillows on which they had been sitting a moment before—pillows that seemed forty or fifty feet square now and loomed high above their heads.

      The Very Young Man took the frightened girl by the hand and led her along the tremendous length of a pile of boxes, blocks long it seemed. These boxes, from their size, might have been rectangular, windowless houses, jammed closely together, and piled one upon the other up into the air almost out of sight.

      Finally they came to a broad passageway between the boxes—a mere crack it would have been before. They turned into it, and, a few feet beyond, came to a larger square space with a box making a roof over it some twenty feet above their heads.

      From this retreat they could see the lower part of the door leading into the other room and could hear from beyond it a muffled roar—the voices of Targo and his men. Hardly were they hidden when the door opened a little. It struck against the bales the Very Young Man had piled against it. For a moment it held, but with the united efforts of the men pushing from the other side, it slowly yielded and swung open.

      Targo stepped into the room. To the Very Young Man he seemed nearly a hundred feet high. Only his feet and ankles were visible at first, from where the Very Young Man was watching. Three other men came with him. They stamped back and forth for a time, moving some of the bales and boxes. Luckily they left undisturbed those nearest the fugitives; after a moment they left, leaving the door open.

      The Very Young Man breathed a long sigh of relief. "Gosh, I'm glad that's over." He spoke in a low tone, although the men in the other room seemed so far away they would hardly have heard him if he had shouted at the top of his voice.

      Alone with the girl now in this great silent room, the Very Young Man felt suddenly embarrassed. "I am one of your brother's friends," he said. "My name's Jack; is yours Aura?"

      "Lylda's sister I am," she answered quietly. "My father told me about you——" Then with a rush came the memory of her father's death, which the startling experiences of the past half-hour had made her forget. Her big, soft eyes filled with tears and her lips quivered. Involuntarily the Very Young Man put his arm about her again and held her close to him. She was so little and frail—so pathetic and so wholly adorable. For a long time they sat in silence; then the girl gently drew away.

      At the doorway they stood and listened; Targo and his followers were still in the adjoining room, talking earnestly. "Loto they have captured," Aura whispered suddenly. "Others of Targo's men have taken him—in a boat—to Orlog. To-morrow they send a messenger to my brother to demand he give up these drugs—or Loto they will kill."

      The Very Young Man waited, breathless. Suddenly he heard Targo laugh—a cruel, cynical laugh. Aura shuddered.

      "And when he has the drug, all of us will he kill. And all in the land too who will not do as he bids."

      The men were rising, evidently in preparation to leave. Aura continued: "They go—now—to Orlog—all but Targo. A little way from here, up the lake shore, a boat is waiting. It will take them there fast."

      With a last look around, Targo and his followers disappeared through the back door of the room. An outer door clanged noisily, and the Very Young Man and Aura were left alone in the house.

      Reoh murdered, Loto stolen! The Very Young Man thought of Lylda and wondered if anything could have happened to her. "Did they speak of your sister?" he asked.

      "Targo said—he—he would put her to death," Aura answered with a shudder.
