The hounds were nearly across; the coyote was within fifty feet of the boulders, when the greyhound, lowering his long, flat head, lunged for the spine of his quarry. The coyote heard him coming, spun on his fore feet, offering his fangs to those of his foe, and threw himself backward just as the jaws of the wolfhound clashed at him and flecked his throat with foam. The two great dogs collided and bounded wide apart, startling a jack rabbit that dived between them into a hole among the rocks. The coyote, on his feet in an instant, caught the motion of the rabbit, and like his shadow, leaped into the air after him for the hole. He was as quick as thought, quicker than either of the hounds. He sprang high over them,--safely over them, we thought,--when, in mid-air, at the turn of the dive, he twisted, heeled half-over, and landed hard against the side of the hole; and the wolfhound pulled him down. It was over; but there was something strange, almost unfair, it seemed, about the finish. Before we got down to the cove both of the dogs had slunk back, cowering from the dead coyote. Then there came to us the buzz of a rattlesnake--a huge, angry reptile that lay coiled in the mouth of the hole. The rabbit had struck and roused the snake. The coyote in his leap had caught the warning whir, but caught it too late to clear both snake and hounds. His twist in the air to clear the snake had cost him his life. So close is the race in the desert world. CHAPTER V FROM T WHARF TO FRANKLIN FIELD Over and over I read the list of saints and martyrs on the wall across the street, thinking dully how men used to suffer for their religion, and how, nowadays, they suffer for their teeth. For I was reclining in a dentist’s chair, blinking through the window at the Boston Public Library, seeing nothing, however, nothing but the tiles on the roof, and the names of Luther, Wesley, Wycliffe, graven on the granite wall, while the dentist burred inside of my cranium and bored down to my toes for nerves. So, at least, it seemed. By and by my gaze wandered blankly off to the square patch of sky in sight above the roof. A black cloud was driving past in the wind away up there. Suddenly a white fleck swept into the cloud, careened, spread two wide wings against it, and rounded a circle. Then another and another, until eight herring gulls were soaring white against the sullen cloud in that little square of sky high over the roofs of Boston. Was this the heart of a vast city? Could I be in a dentist’s chair? There was no doubt about the chair; but how quickly the red-green roof of the Library became the top of some great cliff; the droning noise of traffic in the streets, the wash of waves against the rocks; and yonder on the storm-stained sky those wheeling wings, how like the winds of the ocean, and the raucous voices, how they seemed to fill all the city with the sweep and the sound of the sea!
