On the third morning of his south-chasm leg, he trekked along a ridge, his only feasible route westward. He had cut himself a new staff, after several tries; the first saplings he went for magicked him off by using aversion spells of assorted types. He had no doubt there were many suitable trees he never saw at all, because of their passive "do not notice me" spells. One used a physical repulsion charm directed at cutting objects; every time he slashed at it, his knife veered away.

  About an hour on the way with his new staff, he was still pondering the natural selectivity of magic. The plants with the most effective spells survived best, so became more common, but how many times did stray travelers come by here with knives? Then he realized that he might make good use of that repulsion spell. If he succeeded in cutting a staff from such a tree, would it repel all attacks against him? Obviously this magic was for defense against the depredations of dragons, beavers, and such, not actual knives, and he would certainly feel safer with an anti-dragon staff. No; cutting the tree would kill it, and its magic would abate. But maybe a seed from it--

  No sense consuming time going back; he should be able to locate another such tree. All he had to do was attempt to cut a new staff and note which tree repulsed his knife. He might be able to dig up a small one and take it entire, keeping it alive and effective.

  He moved down the side of the ridge, testing trees. This proved to be more hazardous than anticipated; the knife's approach toward their tender bark brought out the worst in them. One dropped hard fruit on him, barely missing his head; another exhaled sleep perfume that almost stopped his journey right there. But no cutting-aversion spells, now.

  One large tree had a dryad, an inhabiting wood nymph, who looked very fetching, about like Iris at fourteen, but who cursed Bink roundly in most unladylike language. "If you want to carve defenseless things, go carve your own kind!" she screamed. "Go carve the wounded soldier in the ditch, you son of a--" Fortunately she balked at completing the rhyme. Dryads were not supposed to know such language.

  Wounded soldier? Bink located the ditch and explored it carefully. Sure enough, there lay a man in military apparel, blood crusted on his back, groaning piteously.

  "Peace," Bink said. "I will help you, if you permit." Xanth had once needed a real army, but now the soldiers were mostly messengers for the King. Still, their costumes and pride remained.

  "Help me!" the man exclaimed weakly. "I will reward you--somehow."

  Now Bink felt it safe to approach. The soldier was severely wounded and had lost much blood. He was burning with the fever of infection. "I can't do anything for you myself; I'm no doctor, and if I even move you, you may expire. I will return with medication," Bink said. "I must borrow your sword." If the soldier gave up his sword, he was really sick.

  "Return soon--or not at all," the man gasped, raising the hilt.

  Bink took the heavy weapon and climbed out of the ditch. He approached the tree of the dryad. "I need magic," he told her, "Blood restoration, wound healing, fever abatement--that sort of thing. Tell me where I can get them, quickly, or I will chop your tree down."

  "You wouldn't!" she cried, horrified.

  Bink hefted the sword menacingly. At this moment he reminded himself of Jama, the village sword conjurer; the image disgusted him.

  "I'll tell! I'll tell!" she screamed.

  "Okay. Tell." He was relieved; he doubted that he could actually have made himself chop down her tree. That would have killed her, and to no real purpose. Dryads were harmless creatures, pretty to look at; there was no point in molesting them or their cherished tree homes.

  "Three miles to the west. The Spring of Life. Its water will cure anything."

  Bink hesitated. "There is something you're not telling me," he said, hefting the sword again. "What's the catch?"

  "I may not reveal it," she cried. "Anyone who tells--the curse--"

  Bink made as if to chop at the trunk of the tree. The dryad screamed with such utter misery that he abated the effort. He had fought to protect Justin Tree back at home; he could not ravage this one. "All right. I'll risk the curse," he said. He set off westward.

  He found a path leading his way. It was not an inviting one, merely an animal run, so he felt justified in using it with caution. It seemed others knew the route to the Spring. Yet as he approached, he became increasingly nervous. What was the catch, and what was the curse? He really ought to know before he either risked himself or gave the water to the ailing soldier.

  Xanth was the land of magic--but magic had its rules, and its qualifications. It was dangerous to play with magic unless the precise nature of the spell was understood. If this water really could heal the soldier, it was a most strongly enchanted Spring. For that sort of aid, there had to be a price.

  He found the Spring. It was in a depression, under a giant spreading acorn tree. The tree's health augured well for the water; it could hardly be poisoned. But there could be some other menace associated with it. Suppose a river monster were hiding in it, using the water as a lure for the unwary? Injured or dying creatures would be easy prey. A false reputation for healing would attract them from many miles around.

  Bink didn't have time to wait and watch. He had to help the soldier now or it would be too late. So this was a risk he simply had to take.

  He moved cautiously to the Spring. It looked cool and clear. He dipped his canteen into it, keeping his other hand on the sword. But nothing happened; no grim tentacle rose from the depths to challenge him.

  Viewing the filled canteen, he had another thought. Even if the water were not poisoned, it was not necessarily curative. What use to take it to the soldier, if it wouldn't do the job?

  There was one way to find out. He was thirsty anyway. Bink put the canteen to his mouth and sipped.

  The water was chill and good. He drank more deeply, and found it supremely refreshing. It certainly wasn't poisoned.

  He dipped the canteen again and watched the bubbles rise. They distorted the view of his left hand under the water, making it seem as if he had all his fingers. He did not think much about the digit he had lost in childhood, but such a view of a supposedly complete hand teased him unpleasantly.

  He lifted out the canteen--and almost dropped it. His finger was whole! It really was! The childhood injury had been eliminated.

  He flexed it and touched it, amazed. He pinched it and it hurt. No question: his finger was real.

  The Spring really was magic. If it could heal a fifteen-year-old amputation so cleanly and painlessly and instantly, it could heal anything! How about a cold? Bink sniffed--and discovered that his nose was clear. It had cured his sniffles, too.

  No question about it: he could recommend this Spring of Life. A true description for a potent magic. If this Spring were a person, it would be a full Magician.

  Again Bink's natural caution came into play. He still did not know the nature of the catch--or of the curse. Why could no one tell the secret of this Spring? What was the secret? Obviously not the fact of its healing properties; the dryad had told him that, and he could tell it to others. The curse could not be a river monster, for none had struck. Now that Bink was whole and well, he would be much better able to defend himself. Scratch one theory.

  But this did not mean there was no danger. It merely meant the threat was more subtle than he had thought. A subtle danger was the worst of all. The man who fled from the obvious menace of a flaming dragon could succumb to the hidden menace of the peace spell of the pines.

  The soldier was dying. Moments were precious, yet Bink delayed. He had to ferret this out, lest he put both the soldier and himself in greater peril than before. It was said that a person should not look a gift unicorn in the mouth, lest it prove to be enchanted, but Bink always looked.

  He kneeled before the Spring and stared deep into it. Looking it in the mouth, as it were. "O Spring of Life," he murmured. "I come on a mission of mercy, seeking no profit for myself, though I have indeed benefited. I conjure you to reveal your ration
ale, lest I inadvertently trespass." He had little confidence in this formal invocation, since he had no magic with which to enforce it, but it was all he could think of. He just couldn't accept such a wonderful gift without trying to ascertain the payment to be exacted. There was always a price.

  Something swirled deep in the Spring. Bink felt the potent magic of it. It was as if he peered through a hole into another world. Oh, yes this Spring had its own consciousness and pride! The field of its animus rose up to encompass him, and his consciousness plunged through the depths, bringing comprehension. Who imbibes of me may not act against my interest, on pain of forfeiture of all that I bring him.

  Uh-oh. This was a self-preservation spell, plain and simple. But enormously complicated in its execution. Who defined what was or was not contrary to the interests of the Spring? Who but the Spring itself? There would obviously be no lumbering in this region, for cutting trees could damage the environment and change the climate, affecting rainfall. No mining, for that could lower the water table and pollute the Spring. Even the prohibition against revealing the rationale made sense, for people with minor injuries and complaints might not use the magic water if they knew the price in advance. The loggers and miners certainly wouldn't. But any action had extending if diminishing consequences, like the ripples of a stone dropped in a pool. In time such ripples could cover the whole ocean. Or the whole of Xanth, in this case.

  Suppose the Spring decided that its interest was threatened indirectly by some action of the distant King of Xanth, such as levying a tax on lumber that caused the lumbermen to cut more wood in order to pay it. Would the Spring force all its users to oppose the King, perhaps assassinating him? A person who owed his life to the Spring might very well do it.

  It was theoretically possible for this magic Spring to change the whole society of Xanth--even to become its de facto ruler. But the interests of one isolated Spring were not necessarily the interests of the human society. Probably the magic of the Spring could not extend to such extremes, for it would have to be as strong as the massed powers of all the other entities of Xanth. But slowly, given time, it would have its effect. Which made this an ethical question.

  "I cannot accept your covenant," Bink said into the deep swirl. "I hold no animosity toward you, but I cannot pledge to act only in your interest. The interest of the whole of Xanth is paramount. Take back your benefits; I go my own way."

  Now there was anger in the Spring. The unfathomable depths of it roiled. The field of magic rose up again, enveloping him. He would suffer the consequence of his temerity.

  But it faded like a dissipating storm, leaving him...whole. His finger remained healed, and his cold was still cured. He had called the Spring's bluff and won.

  Or had he? Maybe his benefits would not be revoked until he acted specifically against the interest of the Spring. Well, his benefits were minor; he could afford the penalty. He certainly would not be deterred from doing what he felt was right by fear of that consequence.

  Bink stood, keeping the sword in his hand as he slung the strap of the canteen over his shoulder. He turned. A chimera was crawling toward him.

  Bink whipped his sword around, though he was hardly expert in its use. Chimeras were dangerous!

  But in a moment he saw that the creature was in dire straits. The tongue was bonging out of its lion's head, its goat's head was unconscious, and the snake's head at the end of the tail was dragging on the ground. The creature was scraping along on its stomach toward the Spring, trailing blood.

  Bink stood aside and let it pass. He held no malice even for a chimera in this state. He had never before seen a living creature suffering like this. Except the soldier.

  The chimera reached the water and plunged its lion head in, drinking desperately.

  The change was immediate. The goat's head snapped erect and awake, swiveling from its neck in the middle of the back to glare at Bink. The snake head hissed.

  No doubt about it: the chimera was healthy again. But now it was dangerous, for this class of monster hated all things human. It took a step toward Bink, who held his sword tightly before him with both hands, knowing that flight would be futile. If he wounded it, he might escape before it dragged itself back to the Spring for a second restoration.

  But abruptly the thing turned away, without attacking. Bink sighed with relief; he had put up a front, but the last thing he wanted to do was to engage in combat with such a monster, in the presence of an unfriendly Spring.

  There must be a general truce in this vicinity, Bink realized. It was contrary to the interest of the Spring to have predators lurk here, so no hunting or fighting was permitted. Lucky for him!

  He scrambled up the slope and headed east. He hoped the soldier had survived.

  The soldier had. He was tough, as soldiers tended to be; he refused to gasp out his last until nature ripped it from him. Bink dribbled some magic water into his mouth, then poured some over the wound. Suddenly the man was well.

  "What did you do?" he cried. "It is as if I never got stabbed in the back."

  They walked up the hill together. "I fetched water from a magic Spring," Bink explained. He paused at the dryad's tree. "This accommodating nymph very kindly directed me to it."

  "Why, thank you, nymph," the soldier said. "Any favor I can do in return--"

  "Just move on," she said tightly, eyeing the sword in Bink's hands.

  They moved on. "You can't act contrary to the interest of that Spring," Bink said. "Or tell anyone about the price you paid for its help. If you do, you'll be right back where you started. I figured the price was worth it, for you."

  "I'll say! I was doing patrol duty, guarding a patch of the King's eyeball ferns, when somebody--hey, one drink of this elixir and the King's eyes would be perfect without those ferns, wouldn't they? I should take--" He broke off.

  "I can show you where the Spring is," Bink offered. "Anybody can use it, as far as I know."

  "No, it's not that. I just suddenly got the feeling--I don't think the King ought to have this water."

  This simple comment had a profound impact on Bink. Did it confirm his reasoning, that the Spring's influence extended widely and selfishly? Revived health of the King might not be in the interest of the Spring, so--

  But, on the other hand, if the King were cured by Spring water, then the King himself would serve the Spring's interest. Why should the Spring object to that?

  Also, why had Bink himself not suffered the loss of his finger and restoration of his cold when he told the secret to the soldier? He had defied the Spring, yet paid no penalty. Was the curse a mere bluff?

  The soldier extended his hand. "I'm Crombie. Corporal Crombie. You saved my life. How can I repay you?"

  "Oh, I just did what was right," Bink said. "I couldn't just let you die. I'm on my way to the Magician Humfrey, to see if I have any magic talent."

  Crombie put his hand to his beard, pondering. He was rather handsome in that pose. "I can tell you the direction." He closed his eyes, put out his right hand, and slowly rotated. When his pointing finger stabilized, he opened his eyes. "Magician's that way. That's my talent--direction. I can tell you where anything is."

  "I already know the direction," Bink said. "West. My main problem is getting through all this jungle. There's so much hostile magic--"

  "You said it," Crombie agreed heartily. "Almost as much hostile magic as there is in civilized regions. The raiders must have magicked me here, figuring I'd never get out alive and my body would never be found. My shade couldn't avenge me in the deep jungle."

  "Oh, I don't know about that," Bink said, thinking of the shade Donald in the chasm.

  "But now I've recovered, thanks to you. Tell you what: I'll be your bodyguard until you reach the Magician. Is that a fair return?"

  "You really don't need to--"

  "Oh, but I do! Soldier's honor. You did me a good turn, I'll do you a good turn. I insist. I can help a lot. I'll show you." He closed his eyes again, extended his hand, a
nd rotated. When he stopped, he continued: "That's the direction of the greatest threat to your welfare. Want to verify it?"

  "No," Bink said.

  "Well, I do. Danger never went away by being ignored. You have to go out and conquer it. Give me back my sword."

  Bink gave it back, and Crombie proceeded in the direction he had pointed: north.

  Bink followed, disgruntled. He did not want to seek out danger, but he knew it was not right to let the soldier walk into it in his stead. Maybe it was something obvious, like the Gap dragon. But that was no immediate threat, so long as Bink stayed out of the chasm. He fully intended to stay out.

  When Crombie found himself balked by thick brush, he simply slashed it away with his sword. Bink noticed that some of the vegetation gave way before the blade actually struck; if providing a path was the best route to survival, these plants took it. But suppose the soldier hacked into a tangle tree? That could be the danger he had pointed out.

  No--a tangler was deadly to the unwary, but it did not move from the place it had rooted. Since Bink had been going west, not north, no stationary thing was much of a threat to him unless it was west.

  There was a scream. Bink jumped, and Crombie held his sword at the ready. But it was only a woman, cringing and frightened.

  "Speak, girl!" Crombie roared, flourishing his wicked blade. "What mischief do you intend?"

  "Don't hurt me!" she cried. "I am only Dee, lost and alone. I thought you came to rescue me."

  "You lie!" Crombie exclaimed. "You mean harm to this man, my friend who saved my life. Confess!" And he lifted his sword again.

  "For God's sake--let her be!" Bink yelled. "You made a mistake. She's obviously harmless."

  "My talent's never been wrong before," Crombie said. "This is where it pointed your greatest threat."

  "Maybe the threat is behind her, beyond," Bink said. "She was merely in the line of sight."

  Crombie paused. "Could be. I never thought of that." He was evidently a reasonable man, under the violence. "Wait, I'll verify."
