It made no sense. Jason tried to reconcile the modern machine with the barbarian and couldn't. Who was he calling? The existence of one communicator meant there was at least another. Was Rhes a person or a thing? With a mental effort he grabbed hold of his thoughts and braked them to a stop. There was something new here, factors he hadn't counted on. He kept reassuring himself there was an explanation for everything, once you had your facts straight. Jason closed his eyes, shutting out the glaring rays of the sun where it cut through the tree tops, and reconsidered his facts. They separated evenly into two classes; those he had observed for himself, and those he had learned from the city dwellers. This last class of "facts" he would hold, to see if they fitted with what he learned. There was a good chance that most, or all, of them would prove false. "Get up," the voice jarred into his thoughts. "We're leaving." His legs were still numb and hardly usable. The bearded man snorted in disgust and hauled him to his feet, propping him against the outer wall. Jason clutched the knobby bark of the logs when he was left alone. He looked around, soaking up impressions. It was the first time he had been on a farm since he had run away from home. A different world with a different ecology, but the similarity was apparent enough to him. A new-sown field stretched down the hill in front of the shack. Ploughed by a good farmer. Even, well cast furrows that followed the contour of the slope. Another, larger log building was next to this one, probably a barn. There was a snuffling sound behind him and Jason turned quickly--and froze. His hand called for the missing gun and his finger tightened down on a trigger that wasn't there. It had come out of the jungle and padded up quietly behind him. It had six thick legs with clawed feet that dug into the ground. The two-meter long body was covered with matted yellow and black fur, all except the skull and shoulders. These were covered with overlapping horny plates. Jason could see all this because the beast was that close. He waited to die. The mouth opened, a froglike division of the hairless skull, revealing double rows of jagged teeth. "Here, Fido," the bearded man said, coming up behind Jason and snapping his fingers at the same time. The thing bounded forward, brushing past the dazed Jason, and rubbed his head against the man's leg. "Nice doggy," the man said, his fingers scratching under the edge of the carapace where it joined the flesh. The bearded man had brought two of the riding animals out of the barn, saddled and bridled. Jason barely noticed the details of smooth skin and long legs as he swung up on one. His feet were quickly lashed to the stirrups. When they started the skull-headed beast followed them. "Nice doggy!" Jason said, and for no reason started to laugh. The bearded man turned and scowled at him until he was quiet. * * * * * By the time they entered the jungle it was dark. It was impossible to see under the thick foliage, and they used no lights. The animals seemed to know the way. There were scraping noises and shrill calls from the jungle around them, but it didn't bother Jason too much. Perhaps the automatic manner in which the other man undertook the journey reassured him. Or the presence of the "dog" that he felt rather than saw. The trip was a long one, but not too uncomfortable. The regular motion of the animal and his fatigue overcame Jason and he dozed into a fitful sleep, waking with a start each time he slumped forward. In the end he slept sitting up in the saddle. Hours passed this way, until he opened his eyes and saw a square of light before them. The trip was over. His legs were stiff and galled with saddle sores. After his feet were untied getting down was an effort, and he almost fell. A door opened and Jason went in. It took his eyes some moments to get used to the light, until he could make out the form of a man on the bed before him. "Come over here and sit down." The voice was full and strong, accustomed to command. The body was that of an invalid. A blanket covered him to the waist, above that the flesh was sickly white, spotted with red nodules, and hung loosely over the bones. There seemed to be nothing left of the man except skin and skeleton. "Not very nice," the man on the bed said, "but I've grown used to it." His tone changed abruptly. "Naxa said you were from off-world. Is that true?" Jason nodded yes, and his answer stirred the living skeleton to life. The head lifted from the pillow and the red-rimmed eyes sought his with a desperate intensity. "My name is Rhes and I'm a ... grubber. Will you help me?" Jason wondered at the intensity of Rhes' question, all out of proportion to the simple content of its meaning. Yet he could see no reason to give anything other than the first and obvious answer that sprang to his lips. "Of course I'll help you, in whatever way I can. As long as it involves no injury to anyone else. What do you want?" The sick man's head had fallen back limply, exhausted, as Jason talked. But the fire still burned in the eyes. "Feel assured ... I want to injure no others," Rhes said. "Quite the opposite. As you see I am suffering from a disease that our remedies will not stop. Within a few more days I will be dead. Now I have seen ... the city people ... using a device, they press it over a wound or an animal bite. Do you have one of these machines?" "That sounds like a description of the medikit." Jason touched the button at his waist that dropped the medikit into his hand. "I have mine here. It analyzes and treats most ..." "Would you use it on me?" Rhes broke in, his voice suddenly urgent. "I'm sorry," Jason said. "I should have realized." He stepped forward and pressed the machine over one of the inflamed areas on Rhes' chest. The operation light came on and the thin shaft of the analyzer probe slid down. When it withdrew the device hummed, then clicked three times as three separate hypodermic needles lanced into the skin. Then the light went out. "Is that all?" Rhes asked, as he watched Jason stow the medikit back in his belt. Jason nodded, then looked up and noticed the wet marks of tears on the sick man's face. Rhes became aware at the same time and brushed at them angrily. "When a man is sick,&quo............
