Lad hated the nights. In the first place, everybody went to bed and left him alone. In the second, his hard-hearted owners made him sleep on a fluffy rug in a corner of the veranda instead of in his delectable piano-cave. Moreover, there was no food at night. And there was nobody to play with or to go for walks with or to listen to. There was nothing but gloom and silence and dulness. When a puppy takes fifty cat-naps in the course of the day, he cannot always be expected to sleep the night through. It is too much to ask. And Lad’s waking hours at night were times of desolation and of utter boredom. True, he might have consoled himself, as does many a lesser pup, with voicing his woes in a series of melancholy howls. That, in time, would have drawn plenty of human attention to the lonely youngster; even if the attention were not wholly flattering. But Lad did not belong to the howling type. When he was unhappy, he waxed silence. And his sorrowful eyes took on a deeper woe. By the way, if there is anything more sorrowful than the eyes of a collie pup that has never known sorrow, I have yet to see it. No, Lad could not howl. And he could not hunt for squirrels. For these enemies of his were not content with the unsportsmanliness of climbing out of his reach in the daytime, when he chased them; but they added to their sins by joining the rest of the 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 some one 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.
