resolved on a daring move. This creature in front of him,—dog or bear or goat, or whatever it was,—was uncatchable. But by sending a bullet through it, he could bring the animal to a sudden and permanent stop.

Then, snatching up his bag and running at top speed, he himself could easily win clear of the Place before anyone of the household should appear. And his car would be a mile away before the neighborhood could be aroused. Fury at the weird beast and the wrenching strain on his own nerves lent eagerness to his acceptance of the idea.

He reached back again for his pistol, whipped it out, and, coming to a standstill, aimed at the pup. Lad, waiting only to bound over an obstruction in his path, came to a corresponding pause, not ten feet ahead of his playmate.

It was an easy shot. Yet the bullet went several inches above the obligingly waiting dog's back. Nine men out of ten, shooting by moonlight or by flashlight, aim too high. The thief had heard this old marksman-maxim fifty times. But, like most hearers of maxims, he had forgotten it at the one time in his speckled career when it might have been of any use to him.

He had fired. He had missed. In another second, every sleeper in the house and in the gate-lodge would be out of bed. His night's work was a blank, unless—

With a bull rush he hurled himself forward at the interestedly waiting Lad. And, as he sprang, he fired again. Then several things happened.

Everyone, except movie actors and newly-appointed policemen, knows that a man on foot cannot shoot straight, unless he is standing stock still. Yet, as luck would have it, this second shot found a mark where the first and better aimed bullet had gone wild.

Lad had leaped the narrow and deep ditch left along the lawn-edge by workers who were putting in a new water-main for the Place. On the far side of this obstacle he had stopped, and had waited for his friend to follow. But the friend had not followed. Instead, he had been somehow responsible for a spurt of red flame and for a most thrilling racket. Lad was more impressed than ever by the man's wondrous possibilities as a midnight entertainer. He waited, gayly expectant, for more. He got it.

There was a second rackety explosion and a second puff of lightning from the man's out-flung hand. But, this time, something like a red-hot whip-lash smote Lad with horribly agonizing force athwart the right hip.

The man had done this,—the man whom Laddie had thought so friendly and playful!

He had not done it by accident. For his hand had been out-flung 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 agonizing 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 milk-teeth 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 counterattack. 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 defenseless.

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 lest 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.

It was Lad's collie way to pick up offerings (ranging from slippers to very dead fish) and to carry them to the Mistress. Sometimes he was petted for this. Sometimes the offering was lifted gingerly between aloof fingers and tossed back into the lake. But, nobody could well refuse so jingly and pretty a gift as this satchel.

The Master, sketchily attired, came running down the lawn, flashlight in hand. Past him, unnoticed, as he sped toward the ditch, a collie pup limped;—a very unhappy and comfort-seeking puppy who carried in his mouth a blood-spattered brown bag.

"It doesn't make sense to me!" complained the Master, next day, as he told the story for the dozenth time, to a new group of callers. "I heard the shots and I went out to investigate. There he was lying, half in and half out of the ditch. The fellow was unconscious. He didn't get his senses back till after the police came. Then he told some babbling yarn about a creature that had stolen his bag of loot and that had lured him to the ditch. He was all unnerved and upset, and almost out of his head with pain. So the police had little enough trouble in 'sweating' him. He told everything he knew. And there's a wholesale round-up of the motor-robbery bunch going on this afternoon as a result of it. But what I can't understand—"

"It's as clear as day," insisted the Mistress, stroking a silken head that pressed lovingly against her knee. "As clear as day. I was standing in the doorway here when Laddie came pattering up to me and laid a little satchel at my feet. I opened it, and well, it had everything of value in it that had been in the safe over there. That and the thief's story make it perfectly plain. Laddie caught the man as he was climbing out of that window. He got the bag away from him; and the man chased him, firing as he went. And he stumbled into the ditch and—"

"Nonsense!" laughed the Master. "I'll grant all you say about Lad's being the most marvelous puppy on earth. And I'll even believe all the miracles of his cleverness. But when it comes to taking a bag of jewelry from a burglar and then enticing him to a ditch and then coming back here to you with the bag—"

"Then how do you account—?"

"I don't. None of it makes sense to me. As I just said. But, whatever happened, it's turned Laddie into a real watchdog. Did you notice how he went for the police when they started down the drive, last night? We've got a watchdog at last."

"We've got more than a watchdog," amended the Mistress. "An ordinary watchdog would just scare away thieves or bite them. Lad captured the thief and then brought the stolen jewelry back to us. No other
