Harder to understand was the island’s complete desolation. I never saw such a stripped-down ecology. The air of the place carried no flies, no butterflies, no bees, no insects of any kind. The trees sheltered no birds. The plains hid no rodents, no grubs, no worms, no snakes, no scorpions; they gave rise to no other trees, no shrubs, no grasses, no flowers. The ponds harboured no freshwater fish. The seashore teemed with no weeds, no crabs, no crayfish, no coral, no pebbles, no rocks. With the single, notable exception of the meerkats, there was not the least foreign matter on the island, organic or inorganic. It was nothing but shining green algae and shining green trees.

The trees were not parasites. I discovered this one day when I ate so much algae at the base of a small tree that I exposed its roots. I saw that the roots did not go their own independent way into the algae, but rather joined it, became it. Which meant that these trees either lived in a symbiotic relationship with the algae, in a giving-and-taking that was to their mutual advantage, or, simpler still, were an integral part of the algae. I would guess that the latter was the case because the trees did not seem to bear flowers or fruit. I doubt that an independent organism, however intimate the symbiosis it has entered upon, would give up on so essential a part of life as reproduction. The leaves’ appetite for the sun, as testified by their abundance, their breadth and their super-chlorophyll greenness, made me suspect that the trees had primarily an energy-gathering function. But this is conjecture.

There is one last observation I would like to make. It is based on intuition rather than hard evidence. It is this: that the island was not an island in the conventional sense of the term—that is, a small landmass rooted to the floor of the ocean—but was rather a free-floating organism, a ball of algae of leviathan proportions. And it is my hunch that the ponds reached down to the sides of this huge, buoyant mass and opened onto the ocean, which explained the otherwise inexplicable presence in them of dorados and other fish of the open seas.

It would all bear much further study, but unfortunately I lost the algae that I took away.

Just as I returned to life, so did Richard Parker. By dint of stuffing himself with meerkats, his weight went up, his fur began to glisten again, and he returned to his healthy look of old. He kept up his habit of returning to the lifeboat at the end of every day. I always made sure I was there before him, copiously marking my territory with urine so that he didn’t forget who was who and what was whose. But he left at first light and roamed further afield than I did; the island being the same all over, I generally stayed within one area. I saw very little of him during the day. And I grew nervous. I saw how he raked the trees with his forepaws—great deep gouges in the trunks, they were. And I began to hear his hoarse roaring, that aaonh cry as rich as gold or honey and as spine-chilling as the depths of an unsafe mine or a thousand angry bees. That he was searching for a female was not in itself what troubled me; it was that it meant he was comfortable enough on the island to be thinking about producing young. I worried that in this new condition he might not tolerate another male in his territory, his night territory in particular, especially if his insistent cries went unanswered, as surely they would.

One day I was on a walk in the forest. I was walking vigorously, caught up in my own thoughts. I passed a tree—and practically ran into Richard Parker. Both of us were startled. He hissed and reared up on his hind legs, towering over me, his great paws ready to swat me down. I stood frozen to the spot, paralyzed with fear and shock. He dropped back on all fours and moved away. When he had gone three, four paces, he turned and reared up again, growling this time. I continued to stand like a statue. He went another few paces and repeated the threat a third time. Satisfied that I was not a menace, he ambled off. As soon as I had caught my breath and stopped trembling, I brought the whistle to my mouth and started running after him. He had already gone a good distance, but he was still within sight. My running was powerful. He turned, saw me, crouched—and then bolted. I blew into the whistle as hard as I could, wishing that its sound would travel as far and wide as the cry of a lonely tiger.

That night, as he was resting two feet beneath me, I came to the conclusion that I had to step into the circus ring again.

The major difficulty in training animals is that they operate either by instinct or by rote. The shortcut of intelligence to make new associations that are not instinctive is minimally available. Therefore, imprinting in an animal’s mind the artificial connection that if it does a certain action, say, roll over, it will get a treat can be achieved only by mind-numbing repetition. It is a slow process that depends as much on luck as on hard work, all the more so when the animal is an adult. I blew into the whistle till my lungs hurt. I pounded my chest till it was covered with bruises. I shouted “Hep! Hep! Hep!”—my tiger-language command to say “Do!”—thousands of times. I tossed hundreds of meerkat morsels at him that I would gladly have eaten myself. The training of tigers is no easy feat. They are considerably less flexible in their mental make-up than other animals that are commonly trained in circuses and zoos—sea lions and chimpanzees, for example. But I don’t want to take too much credit for what I managed to do with Richard Parker. My good fortune, the fortune that saved my life, was that he was not only a young adult but a pliable young adult, an omega animal. I was afraid that conditions on the island might play against me, that with such an abundance of food and water and so much space he might become relaxed and confident, less open to my influence. But he remained tense. I knew him well enough to sense it. At night in the lifeboat he was unsettled and noisy. I assigned this tension to the new environment of the island; any change, even positive, will make an animal tense. Whatever the cause, the strain he was under meant that he continued to show a readiness to oblige; more, that he felt a need to oblige.

I trained him to jump through a hoop I made with thin branches. It was a simple routine of four jumps. Each one earned him part of a meerkat. As he lumbered towards me, I first held the hoop at the end of my left arm, some three feet off the ground. When he had leapt through it, and as he finished his run, I took hold of the hoop with my right hand and, my back to him, commanded him to return and leap through it again. For the third jump I knelt on the ground and held the hoop over my head. It was a nerve-racking experience to see him come my way. I never lost the fear that he would not jump but attack me. Thankfully, he jumped every time. After which I got up and tossed the hoop so that it rolled like a wheel. Richard Parker was supposed to follow it and go through it one last time before it fell over. He was never very good at this last part of the act, either because I failed to throw the hoop properly or because he clumsily ran into it. But at least he followed it, which meant he got away from me. He was always filled with amazement when the hoop fell over. He would look at it intently, as if it were some great fellow animal he had been running with that had collapsed unexpectedly. He would stay next to it, sniffing it. I would throw him his last treat and move away.

Eventually I quit the boat. It seemed absurd to spend my nights in such cramped quarters with an animal who was becoming roomy in his needs, when I could have an entire island. I decided the safe thing to do would be to sleep in a tree. Richard Parker’s nocturnal practice of sleeping in the lifeboat was never a law in my mind. It would not be a good idea for me to be outside my territory, sleeping and defenceless on the ground, the one time he decided to go for a midnight stroll.
