He had not done it by accident. For his hand had been outflung directly at the pup, just as once had been the arm of the kennelman, back at Lad’s birthplace, in beating a disobedient mongrel. It was the only beating Lad had ever seen. And it had stuck, shudderingly, in his uncannily sensitive memory. Yet now, he himself had just had a like experience. In an instant, the pup’s trustful friendliness was gone. The man had come on the Place, at dead of night, and had struck him. That must be paid for! Never would the pup forget his agonising lesson that night intruders are not to be trusted or even to be tolerated. Within a single second, he had graduated from a little friend of all the world, into a vigilant watchdog. With a snarl, he dropped the bag and whizzed forward at his assailant. Needle-sharp milkteeth bared, head low, ruff abristle, friendly soft eyes as ferocious as a wolf’s, he charged. There had been scarce a breathing-space between the second report of the pistol and the collie’s counter-attack. But there had been time enough for the onward-plunging thief to step into the narrow lip of the water-pipe ditch. The momentum of his own rush hurled the upper part of his body forward. But his left leg, caught between the ditch-sides, did not keep pace with the rest of him. There was a hideous snapping sound, a screech of mortal anguish; and the man crashed to earth, in a dead faint of pain and shock,—his broken left leg still thrust at an impossible angle in the ditch. Lad checked himself midway in his own fierce charge. Teeth bare, throat agrowl, he hesitated. It had seemed to him right and natural to assail the man who had struck him so painfully. But now this same man was lying still and helpless under him. And the sporting instincts of a hundred generations of thoroughbreds cried out to him not to mangle the defenceless. Wherefore, he stood, irresolute; alert for sign of movement on the part of his foe. But there was no such sign. And the light bullet-graze on his hip was hurting like the very mischief. Moreover, every window in the house beyond was blossoming forth into lights. There were sounds,—reassuring human sounds. And doors were opening. His deities were coming forth. All at once, Laddie stopped being a vengeful beast of prey; and remembered that he was a very small and very much hurt and very lonely and worried puppy. He craved the Mistress’s dear touch on his wound, and a word of crooning comfort from her soft voice. This yearning was mingled with a doubt less perhaps he had been transgressing the Place’s Law, in some new way; and lest he might have let himself in for a scolding. The Law was still so queer and so illogical! Lad started toward the house. Then, pausing, he picked up the bag which had been so exhilarating a plaything for him this past few minutes and which he had forgotten in his pain.
