"There is a species of tree here, not too common, with a thickened trunk. It stores water during the rainy season to live on in the hot months. Since we are in the transition period between rains, we could tap it--if we locate one of the trees. How about that, Tau? Dare we drink that without a purifier?" "Probably a choice of two evils, sir. But we have had our preventive shots. Personally, I'd rather battle disease than take a chance on a mind-twisting drug. You can go without water just so long...." "I'd like to have a little talk with Lumbrilo," remarked Jellico, the mildness in his voice very deceptive. "I'm _going_ to have a little talk with Lumbrilo, if and when we see him again!" promised Tau. "What are our chances, sir?" Dane asked. He screwed the cap back on his canteen, his mouth feeling twice as dry since he knew he dared not drink. "Well, we've faced gambles before." Tau sealed the medical kit. "I'd like to see one of those trees before sundown. And I don't want to face another pointed rock today!" "Why the leopard?" asked Jellico reflectively. "Another case of using flame to fight fire? But Lumbrilo wasn't among those present to be impressed." Tau rubbed his hand across his forehead. "I don't really know, sir. Maybe I could have made the ape vanish without a counter projection, but I don't think so. With these hallucinations it is better to battle one vision against another for the benefit of those involved. And I can't even tell you why I selected a leopard--it just flashed into mind as about the fastest and most deadly animal fighter I could recall at that moment." "You'd better work out a good list of such fighters." Jellico's grim humor showed again. "I can supply a few if you need them. Not that I don't share your hope we won't see any more trigger rocks. Here comes Asaki with his wandering boy." The Chief Ranger was half-leading, half-supporting his hunter, and Nymani seemed only half-conscious. Tau got to his feet and hurried to meet them. It would appear that their search for the water tree would be delayed. VI They withdrew to a spot hacked from the edge of the jungle, leaving a screen of green between them and the traitorous up-slope. But within the few hours of daylight left them, it was proven that Asaki had been overly optimistic in his hopes of discovering a water tree. They were now in a narrow tongue of land between the range and the swamps, and this territory was limited. Nymani, still shaken, was of little help, and the spacemen did not dare to strike out into unexplored land alone.
