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,
