Avoid the unhappy ending, the harsh, the brutal, the tragic, the horrible -- if you care to see in print things you write. (In this connection don't do as I do, but do as I say.
But especially he loved to run in the dim twilight of the summer midnights, listening to the subdued and sleepy murmurs of the forest, reading signs and sounds as a man may read a book, and seeking for the mysterious something that called -- called, waking or sleeping, at all times, for him to come.
Thus it was that in obedience to the law laid down by his mother, and in obedience to the law of that unknown and nameless thing, fear, he kept away from the mouth of the cave.
There is an ecstasy that marks the summit of life, and beyond which life cannot rise. And such is the paradox of living, this ecstasy comes when one is most alive, and it comes as a complete forgetfulness that one is alive. This ecstasy, this forgetfulness of living, comes to the artist, caught up and out of himself in a sheet of flame; it comes to the soldier, war-mad in a stricken field and refusing quarter; and it came to Buck, leading the pack, sounding the old wolf-cry, straining after the food that was alive and that fled swiftly before him through the moonlight.
Deep in the forest a call was sounding, and as often as he heard this call, mysteriously thrilling and luring, he felt compelled to turn his back upon the fire and the beaten earth around it, and to plunge into the forest, and on and on, he knew not where or why; nor did he wonder where or why, the call sounding imperiously, deep in the forest.
But it did not all happen in a day, this giving over of himself, body and soul, to the man-animals. He could not immediately forego his wild heritage and his memories of the Wild. There were days when he crept to the edge of the forest and stood and listened to something calling him far and away.

It did not lead him to meditate upon his frailty as a creature of temperature, and upon man's frailty in general, able only to live within certain narrow limits of heat and cold; and from there on it did not lead him to the conjectural field of immortality and man's place in the universe.
A vast silence reigned over the land. The land itself was a desolation, lifeless, without movement, so lone and cold that the spirit of it was not even that of sadness. There was a hint in it of laughter, but of laughter more terrible than any sadness-a laughter that was mirthless as the smile of the Sphinx, a laughter cold as the frost and partaking of the grimness of infallibility. It was the masterful and incommunicable wisdom of eternity laughing at the futility of life and the effort of life. It was the Wild, the savage, frozen-hearted Northland Wild.
You look back and see how hard you worked and how poor you were, and how desperately anxious you were to succeed, and all you can remember is how happy you were.
He was always striving to attain it. The life that was so swiftly expanding within him, urged him continually toward the wall of light. The life that was within him knew that it was the one way out, the way he was predestined to tread.
Men do not knowingly drink for the effect alcohol produces on the body. What they drink for is the brain-effect; and if it must come through the body, so much the worse for the body.
