world,—except Lad,—in sleeping all night. Even the lake that was so friendly by day was a chilly and forbidding playfellow on the cool North Jersey nights.

There was nothing for a poor lonely pup to do but stretch out on his rug and stare in unhappy silence up the driveway, in the impossible hope that someone might happen along through the darkness to play with him.

At such an hour and in such lonesomeness, Lad would gladly have tossed aside all prejudices of caste,—and all his natural dislikes, and would have frolicked in mad joy with the veriest stranger. Anything was better than this drear solitude throughout the million hours before the first of the maids should be stirring or the first of the farmhands report for work. Yes, night was a disgusting time; and it had not one single redeeming trait for the puppy.

Lad was not even consoled by the knowledge that he was guarding the slumbrous house. He was not guarding it. He had not the very remotest idea what it meant to be a watchdog. In all his five months he had never learned that there is unfriendliness in the world; or that there is anything to guard a house against.

True, it was instinctive with him to bark when People came down the drive, or appeared at the gates without warning. But more than once the Master had bidden him be silent when a rackety Puppy salvo of barking had broken in on the arrival of some guest. And Lad was still in perplexed doubt as to whether barking was something forbidden or merely limited.

One night,—a solemn, black, breathless August night, when half-visible heat lightning turned the murk of the western horizon to pulses of dirty sulphur, Lad awoke from a fitful dream of chasing squirrels which had never learned to climb.

He sat up on his rug, blinking around through the gloom in the half hope that some of those non-climbing squirrels might still be in sight. As they were not, he sighed unhappily and prepared to lay his classic young head back again on the rug for another spell of night-shortening sleep.

But, before his head could touch the rug, he reared it and half of his small body from the floor and focused his nearsighted eyes on the driveway. At the same time, his tail began to wag a thumping welcome.

Now, by day, a dog cannot see so far nor so clearly as can a human. But by night,—for comparatively short distances,—he can see much better than can his master. By day or by darkness, his keen hearing and keener scent make up for all defects of eyesight.

And now three of Lad's senses told him he was no longer alone in his tedious vigil. Down the drive, moving with amusing slowness and silence, a man was coming. He was on foot. And he was fairly well dressed. Dogs, the foremost snobs in creation,—are quick to note the difference between a well-clad and a disreputable stranger.

Here unquestionably was a visitor:—some such man as so often came to the Place and paid such flattering attention to the puppy. No longer need Lad be bored by the solitude of this particular night. Someone was coming towards the house;—and carrying a small bag under his arm. Someone to make friends with. Lad was very happy.

Deep in his throat a welcoming bark was born. But he stilled it. Once, when he had barked at the approach of a stranger, the stranger had gone away. If this stranger were to go away, all the night's fun would go with him. Also, no later than yesterday, the Master had scolded Lad for barking at a man who had called. Wherefore the dog held his peace.

Getting to his feet and stretching himself, fore and aft, in true collie fashion, the pup gamboled up the drive to meet the visitor.

The man was feeling his way through the pitch darkness, groping cautiously; halting once or twice for a smolder of lightning to silhouette the house he was nearing. In a wooded lane, a quarter mile away, his lightless motor car waited.

Lad trotted up to him, the tiny white feet noiseless in the soft dust of the drive. The man did not see him, but passed so close to the dog's hospitably upthrust nose that he all but touched it.

Only slightly rebuffed at such chill lack of cordiality, Lad fell in behind him, tail awag, and followed him to the porch. When the guest should ring the bell, the Master or one of the maids would come to the door. There would be lights and talk; and perhaps Laddie himself might be allowed to slip in to his beloved cave.

But the man did not ring. He did not stop at the door at all. On tiptoe he skirted the veranda to the old-fashioned bay windows at the south side of the living room; windows with catches as old-fashioned and as simple to open as themselves.

Lad padded along, a pace or so to the rear;—still hopeful of being petted or perhaps even romped with. The man gave a faint but promising sign of intent to romp, by swinging his small and very shiny brown bag to and fro as he walked. Thus ever did the Master swing Lad's precious canton flannel doll before throwing it for him to retrieve. Lad made a tentative snap at the bag, his tail wagging harder than ever. But he missed it. And, in another moment the man stopped swinging the bag and tucked it under his arm again as he began to mumble with a bit of steel.

There was the very faintest of clicks. Then, noiselessly the window slid upward. A second fumbling sent the wooden inside shutters ajar. The man worked with no uncertainty. Ever since his visit to the Place, a week earlier, behind the aegis of a big and bright and newly forged telephone-inspector badge, he had carried in his trained memory the location of windows and of obstructing furniture and of the primitive small safe in the living room wall, with its pitifully pickable lock;—the safe wherein the Place's few bits of valuable jewelry and other compact treasures reposed at night.

Lad was tempted to follow the creeping body and the fascinatingly swinging bag indoors. But his one effort to enter the house,—with muddy paws,—by way of an open window, had been rebuked by the Lawgivers. He had been led to understand that really well-bred little dogs come in by way of the door; and then only on permission.

So he waited, doubtfully, at the veranda edge; in the hope that his new friend might reappear or that the Master might perhaps want to show off his pup to the caller, as so often the Master was wont to do.

Head cocked to one side, tulip ears alert, Laddie stood listening. To the keenest human ears the thief's soft progress across the wide living room to the wall-safe would have been all but inaudible. But Lad could follow every phase of it; the cautious skirting of each chair; the hesitant pause as a bit of ancient furniture creaked; the halt in front of the safe; the queer grinding noise, muffled but persevering, at the lock; then the faint creak of the swinging iron door, and the deft groping of fingers.

Soon, the man started back toward the pale oblong of gloom which marked the window's outlines from the surrounding black. Lad's tail began to wag again. Apparently, this eccentric person was coming out, after all, to keep him company. Now, the man was kneeling on the window-seat. Now, in gingerly fashion, he reached forward and set the small bag down on the veranda; before negotiating the climb across the broad seat,—a climb that might well call for the use of both his hands.

Lad was entranced. Here was a game he understood. Thus, more than once, had the Mistress tossed out to him his flannel doll, as he had stood in pathetic invitation on the porch, looking in at her as she read or talked. She had laughed at his wild tossings and other maltreatments of the limp doll. He had felt he was scoring a real hit. And this hit he decided to repeat.

Snatching up the swollen little satchel, almost before it left the intruder's hand, Lad shook it, joyously, reveling in the faint clink and jingle of the contents. He backed playfully away; the bag-handle swinging in his jaws. Crouching low, he wagged his tail in ardent invitation to the stranger to chase him and get back the
