LnR 093 TO BUILD A FIRE 2 by Jack London

As he turned to go on, he spat speculatively.  There was a sharp, explosive crackle that startled him.  He spat again.  And again, in the air, before it could fall to the snow, the spittle crackled.  He knew that at fifty below spittle crackled on the snow, but this spittle had crackled in the air.  Undoubtedly it was colder than fifty below—how much colder he did not know.  But the temperature did not matter.  He was bound for the old claim on the left fork of Henderson Creek, where the boys were already.  They had come over across the divide from the Indian Creek country, while he had come the roundabout way to take a look at the possibilities of getting out logs in the spring from the islands in the Yukon.  He would be in to camp by six o’clock; a bit after dark, it was true, but the boys would be there, a fire would be going, and a hot supper would be ready.  As for lunch, he pressed his hand against the protruding bundle under his jacket.  It was also under his shirt, wrapped up in a handkerchief and lying against the naked skin.  It was the only way to keep the biscuits from freezing.  He smiled agreeably to himself as he thought of those biscuits, each cut open and sopped in bacon grease, and each enclosing a generous slice of fried bacon.

He plunged in among the big spruce trees.  The trail was faint.  A foot of snow had fallen since the last sled had passed over, and he was glad he was without a sled, travelling light.  In fact, he carried nothing but the lunch wrapped in the handkerchief.  He was surprised, however, at the cold.  It certainly was cold, he concluded, as he rubbed his numbed nose and cheek-bones with his mittened hand.  He was a warm-whiskered man, but the hair on his face did not protect the high cheek-bones and the eager nose that thrust itself aggressively into the frosty air.

At the man’s heels trotted a dog, a big native husky, the proper wolf-dog, grey-coated and without any visible or temperamental difference from its brother, the wild wolf.  The animal was depressed by the tremendous cold.  It knew that it was no time for travelling.  Its instinct told it a truer tale than was told to the man by the man’s judgment.  In reality, it was not merely colder than fifty below zero; it was colder than sixty below, than seventy below.  It was seventy-five below zero.  Since the freezing-point is thirty-two above zero, it meant that one hundred and seven degrees of frost obtained.  The dog did not know anything about thermometers.  Possibly in its brain there was no sharp consciousness of a condition of very cold such as was in the man’s brain.  But the brute had its instinct.  It experienced a vague but menacing apprehension that subdued it and made it slink along at the man’s heels, and that made it question eagerly every unwonted movement of the man as if expecting him to go into camp or to seek shelter somewhere and build a fire.  The dog had learned fire, and it wanted fire, or else to burrow under the snow and cuddle its warmth away from the air.
