The Story

Buck reigned like a king over Judge Miller's sprawling estate in the sun-warmed Santa Clara Valley. He was no mere kennel dog but a pampered aristocrat, roaming the vineyards, certain the whole comfortable world belonged to him.

But far to the north, men had struck gold in the Klondike, and they hungered for strong dogs to haul their sleds. Therefore Manuel, a gardener drowning in gambling debts, slipped a rope around Buck's neck one night and quietly sold him away.

Buck went trusting, but the stranger tightened the rope until he could not breathe. Enraged, Buck fought, yet the more he struggled the more he was choked. Therefore he was flung into a crate and shipped north by rail, bewildered and betrayed.

When the crate finally opened, a thick-set man in a red sweater waited with a club. Buck charged him in fury, but blow after blow beat him down. Therefore Buck learned his first hard lesson: a man with a club was a master to be obeyed.

Buck was then sold to François and Perrault, two Canadian couriers carrying government mail. They led him aboard a ship bound for the icy Yukon, and when at last he stepped ashore, Buck stared in wonder, for here the ground was white, cold, and strange.

That first night, a friendly dog named Curly approached a huskie too boldly. In an instant the pack fell upon her and tore her down. Buck watched, horrified, and understood: in this North there was no fair play, only the law of fang.

Then François buckled Buck into the sled harness beside the other dogs. It shamed him at first, but Buck was clever, and he watched and copied his teammates. Therefore he swiftly learned to haul, to turn, and to answer the drivers' every call.

But one dog hated him: Spitz, the fierce lead dog who ruled the team by tooth and terror. Spitz sensed in Buck a rival for command. Therefore a slow, simmering war began between them, each waiting for the other to falter.

Night after night the team ran across frozen rivers and silent forests, half-starved and bone-tired. Buck grew lean and savage, and old instincts he had never known began to wake inside him, the ghost-memories of wild ancestors stirring in his blood.

One night the team gave chase to a snowshoe rabbit, and Spitz cut ahead to steal Buck's kill. That treachery was the final spark. Therefore Buck turned on Spitz at last, and the two great dogs faced each other in the moonlight for a fight to the death.

They slashed and circled, fangs flashing, but Spitz was the cleverer fighter and Buck bled. Then Buck seized on a cunning stroke and broke Spitz's legs one by one. Therefore Spitz went down, and the waiting pack closed in and finished him.

With Spitz gone, Buck demanded the leader's place, and François, impressed, harnessed him at the front. Under Buck the ragged team ran faster and truer than ever before. Therefore he proved himself not merely strong, but a true master of dogs.

But the couriers were ordered elsewhere, and Buck's team was sold to a Scotch mail-driver hauling heavy loads. The runs grew longer and crueler, mile upon endless mile, until the dogs were worn thin and one by one began to fail.

Then the exhausted team fell into the hands of three green newcomers from the States: Hal and Charles, and Charles's young wife. They knew nothing of the trail, piled the sled absurdly high, and packed foolish comforts they would never need.

The woman, Mercedes, wept and rode on the sled instead of walking, adding still more weight. Therefore the food ran out long before it should have, and the starving, beaten dogs staggered and dropped dead in their traces one after another.

At last the ragged outfit limped into the camp of John Thornton, a quiet, weathered man mending his moccasins by the fire. He warned them the spring ice was rotten and would not hold. But Hal only cursed and ordered the dogs onward.

Buck, sensing doom, refused to rise no matter how Hal beat him. Something in John Thornton snapped at the cruelty. Therefore he leapt up, drove Hal back, and cut the half-dead dog free from the harness, keeping Buck beside his fire.

Hal cursed and whipped the others out onto the frozen river. But a quarter mile on, the rotten ice gave way beneath them. Therefore the sled, the dogs, and all three foolish newcomers vanished into the freezing water and were gone.

So Buck came to belong to John Thornton, and for the first time in his hard life he was truly loved. Thornton nursed him strong again, and a fierce, adoring devotion woke in Buck's heart, a love he had never felt for any master.

That love was soon tested. When Thornton was swept into wild rapids, Buck plunged after him through the killing current. Battered against the rocks, he dragged his master to shore. Therefore each had now saved the other, and their bond was sealed in blood.

Later, in a rough frontier hall, Thornton boasted that Buck could break out a sled loaded with a thousand pounds and haul it. Men laughed and wagered heavily against him. Therefore the great test was set, a fortune riding on one dog's back.

Buck threw his whole heart into the frozen harness, muscles cracking, as Thornton whispered his love into his ear. Inch by grinding inch, the impossible sled broke free and moved. Therefore Buck won his master a fortune, and the watching men fell silent in awe.

With that gold, Thornton and his partners struck east into untouched wilderness to hunt a lost mine. There, in the vast silence, an old wildness pulled ever harder at Buck. Night after night a far-off howl seemed to call him away into the trees.

But one evening Buck loped back toward camp and felt a terrible stillness in the air. He found the sled-dogs slaughtered and John Thornton lying dead, killed by a band of Yeehat hunters who had fallen upon the camp.

Grief turned to blazing fury. Buck hurled himself upon the Yeehats, tearing through them like a storm of the wild until the survivors fled in terror. Therefore the last tie binding him to man was cut, for the one being he loved was gone.

With Thornton dead, nothing in the world of men could hold Buck any longer. When a wolf pack swept through the valley, he answered their song and joined them. Therefore the pampered dog of the sunlit valley became at last a creature wholly of the wild.

In the years after, the Yeehats told of a great ghostly wolf that ran at the head of the pack, cleverer and more terrible than the rest. And each summer Buck returned once, alone, to mourn beside the place where his master had died.

What it means

Buck began slipping into the forest for days, befriending a wild timber wolf and running at his side. Then he hunted alone, pulling down a great bull moose. As Jack London wrote, 'There is an ecstasy that marks the summit of life,' and Buck, at the kill, had found it.

London's tale is far more than a dog's adventure. It asks how thin the skin of civilization truly is, and how near the surface the ancient instincts still sleep. Strip away comfort, and the wild ancestor within, beast or human, wakes and answers the call.
