I believe I do not wish any of the pie

But if you start a swift-footed dog after him, you will enjoy it ever so much— especially if it is a dog that has a good opinion of himself, and has been brought up to think he knows something about speed. The cayote will go swinging gently off on that deceitful trot of his, and every little while he will smile a fraudful smile over his shoulder that will fill that dog entirely full of encouragement and worldly ambition, and make him lay his head still lower to the ground, and stretch his neck further to the front, and pant more fiercely, and stick his tail out straighter behind, and move his furious legs with a yet wilder frenzy, and leave a broader and broader, and higher and denser cloud of desert sand smoking behind, and marking his long wake across the level plain! And all this time the dog is only a short twenty feet behind the cayote, and to save the soul of him he cannot understand why it is that he cannot get perceptibly closer; and he begins to get aggravated, and it makes him madder and madder to see how gently the cayote glides along and never pants or sweats or ceases to smile; and he grows still more and more incensed to see how shamefully he has been taken in by an entire stranger, and what an ignoble swindle that long, calm, soft-footed trot is; and next he notices that he is getting fagged, and that the cayote actually has to slacken speed a little to keep from running away from him—and then that town-dog is mad in earnest, and he begins to strain and weep and swear, and paw the sand higher than ever, and reach for the cayote with concentrated and desperate energy. This “spurt” finds him six feet behind the gliding enemy, and two miles from his friends. And then, in the instant that a wild new hope is lighting up his face, the cayote turns and smiles blandly upon him once more, and with a something about it which seems to say: “Well, I shall have to tear myself away from you, bub—business is business, and it will not do for me to be fooling along this way all day”—and forthwith there is a rushing sound, and the sudden splitting of a long crack through the atmosphere, and behold that dog is solitary and alone in the midst of a vast solitude! 

It makes his head swim. He stops, and looks all around; climbs the nearest sand-mound, and gazes into the distance; shakes his head reflectively, and then, without a word, he turns and jogs along back to his train, and takes up a humble position under the hindmost wagon, and feels unspeakably mean, and looks ashamed, and hangs his tail at half-mast for a week. And for as much as a year after that, whenever there is a great hue and cry after a cayote, that dog will merely glance in that direction without emotion, and apparently observe to himself, “I believe I do not wish any of the pie.”
