At once the boys joined gleesomely in the chase, outdistancing the officer, just as the latter fired a second shot.

Lad felt a white-hot ridge of pain cut along his left flank like a whip-lash. He wheeled to face his invisible foe, and he found himself looking at a half-dozen boys who charged whoopingly down on him. Behind the boys clumped a man in blue flourishing something bright.

Lad had no taste for this sort of attention. Always he had loathed strangers, and these new strangers seemed bent on catching him—on barring his homeward way.

He wheeled around again and continued his westward journey at a faster pace. The hue-and-cry broke into louder yells and three or four new recruits joined the pursuers. The yap of "Mad dog! Mad dog!" filled the air.

Not one of these people—not even the policeman himself—had any evidence that the collie was mad. There are not two really rabid dogs seen at large in New York or in any other city in the course of a year. Yet, at the back of the human throat ever lurks that fool-cry of "Mad dog!"—ever ready to leap forth into shouted words at the faintest provocation.

One wonders, disgustedly, how many thousand luckless and totally harmless pet dogs in the course of a year are thus hunted down and shot or kicked or stoned to death in the sacred name of Humanity, just because some idiot mistakes a hanging tongue or an uncertainty of direction for signs of that semi-phantom malady known as "rabies."

A dog is lost. He wanders to and fro in bewilderment. Boys pelt or chase him. His tongue lolls and his eyes glaze with fear. Then, ever, rises the yell of "Mad Dog!" And a friendly, lovable pet is joyfully done to death.

Lad crossed Broadway, threading his way through the trolley-and-taxi procession, and galloped down the hill toward Riverside Park. Close always at his heels followed the shouting crowd. Twice, by sprinting, the patrolman gained the front rank of the hunt, and twice he fired—both bullets going wide. Across West End Avenue and across Riverside Drive went Lad, hard-pressed and fleeing at top speed. The cross-street ran directly down to a pier that jutted a hundred feet out into the Hudson River.

Along this pier flew Lad, not in panic terror, but none the less resolved that these howling New Yorkers should not catch him and prevent his going home.

Onto the pier the clattering hue-and-cry followed. A dock watchman, as Lad flashed by, hurled a heavy joist of wood at the dog. It whizzed past the flying hind legs, scoring the barest of misses.
