we must discover and speedily, sir. Or else we shall be lost among the unreal and the real.”
“You also have the power. You can save us!” Asaki protested.
Tau drew his arm across his face. Very little of the normal color had returned to his thin, mobile features. He still leaned against Dane’s supporting arm.
“A man can do only so much, sir. To battle Lumbrilo on his own ground is exhausting and I can not fight so very often.”
“But will he not also be exhausted?”
“I wonder....” Tau gazed beyond the Khatkan to the barren ground where leopard and rock ape had ceased to be. “This magic is a tricky thing, sir. It builds and feeds upon a man’s own imagination and inner fears. Lumbrilo, having triggered ours, need not strive at all, but let us ourselves raise that which will attack us.”
“Drugs?” demanded Jellico.
Tau gave a start sufficient to take him out of Dane’s loose hold. His hand went to the packet of aid supplies which was his own care, his eyes round with wonder and then shrewdly alert.
“Captain, we disinfected those thorn punctures of yours. Thorson, your foot salve.... But, no, I didn’t use anything—”
“You forget, Craig, we all had scratches after that fight with the apes.”
Tau sat down on the ground. With feverish haste he unsealed his medical supplies, laid out some containers. Then delicately he opened each, examined its contents closely by eye, by smell, and two by taste. When he was done he shook his head.
“If these have been in any way meddled with, I would need laboratory analysis to detect it. And I don’t believe that Lumbrilo could hide traces of his work so cleverly. Or has he been off-planet? Had much to do with off-worlders?” he asked the Chief Ranger.
“By the nature of his position he is forbidden to space voyage, to have any close relationship with any off-worlder. I do not think, medic, he would choose your healing substances for his mischief. There would only be chance to aid him then in producing the effects he wants. Though there is often call for first aid in travel, he could not be certain you would use any of your drugs on this trip to the preserve.”
“And Lumbrilo was certain. He threatened something such as this,” Jellico reminded them.
“So it would be something which we would all use, which we had to depend upon....”
“The water!” Dane had been holding his own canteen ready to drink. But as that possible explanation dawned in his mind, he smelled instead of tasted the liquid sloshing inside. There was no odor he could detect. But he remembered Tau commenting on the powdered purifier pills at their first camp.
“That’s it!” Tau dug further into his kit, brought out the vial of white powder with its grainy lumps. Pouring a little into the palm of his hand he smelled it, touched it with the tip of his tongue. “Purifier and something else,” he reported. “It could be one of half a dozen drugs, or some native stuff from here which we’ve never classified.”
“True. There are drugs we have found here.” Asaki scowled down at the green mat of jungle. “So our water is poisoned?”
“Do you always purify it?” Tau asked the Chief Ranger. “Surely during the centuries since your ancestors landed on Khatka you must have adapted to native water. You couldn’t have lived otherwise. We must use the purifier, but must you?”
“There is water and water.” Asaki shook his own canteen, his scowl growing fiercer as the gurgle from its depths was heard. “From springs on the other side of the mountains we drink—yes. But over here, this close to the Mygra swamps, we have not done so. We may have to chance it.”
“Do you think we are literally poisoned?” Jellico bored directly to the heart of their private fears.
“None of us have been drinking too heavily,” Tau observed thoughtfully. “And I don’t believe Lumbrilo had outright killing in mind. How long the effect will last I have no way of telling.”
“If we saw one rock ape,” Dane wondered, “why didn’t we see others? And why here and now?”
“That!” Tau pointed ahead on the trail Asaki had picked for their ascent. For a long moment Dane could see nothing of any interest there and then he located it—a finger of rock. It did not point directly skyward this time, in fact it slanted so that its tip indicated their back trail. Yet in outline the spire was very similar to that outcrop from which the real rock ape had charged them the day before.
Asaki exclaimed in his own tongue and slapped his hand hard against the stock of the needler.
“We saw that and so again we saw an ape also! Had earlier we been charged by graz or jumped by a lion in such a place, then again we would have been faced by graz or lion here!”
Captain Jellico gave a bark of laughter colored only by the most sardonic humor. “Clever enough. He merely leaves it to us to select our own ghost and then repeat the performance in the next proper setting. I wonder how many rocks shaped like that one there are in these mountains? And how long will a rock ape continue to pop out from behind each one we do find?”
“Who knows? But as long as we drink this water we’re going to continue to have trouble; I feel safe in promising that,” Tau replied. He put the vial of doctored purifier into a separate pocket of his medical kit. “It may be a problem of how long we can go without water.”
“Perhaps,” Asaki said softly. “Only not all the water on Khatka comes running in streams.”
“Fruit?” Tau asked.
“No, trees. Lumbrilo is not a hunter, nor could he be certain when and where his magic would go to work. Unless the flitter was deliberately sabotaged, he was planning for us to use our canteens in the preserve. That is lion country and there are long distances between springs. This is jungle below us and there is a source there I think we can safely tap. But first I must find Nymani and prove to him that this is truly deviltry of a sort, but not demon inspired.”
He was gone, running lightly down-slope in the direction his hunter had taken, and Dane spoke to Captain Jellico.
“What’s this about water in trees, sir?”
“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,
