To Lad, the giant collie, this was always a trying season. For longer than he could remember, Lad had been the official watchdog of the Place. And his chief duties were to keep two-footed and four-footed strays from trespassing thereon. To an inch, he knew the boundaries of the Master's land. And he knew that no human intruder was to be molested; so long as such intruder had the sense to walk straight down the driveway to the house. But woe to the tramp or other trespasser who chanced to come cross lots or to wander in any way off the drive! Woe also to such occasional cattle or other livestock as drifted in from the road or by way of a casual fence-gap! Human invaders were to be met in drastic fashion. Quadruped trespassers were to be rounded up and swept at a gallop up the drive and out into the highroad. With cattle or with stray horses this was an easy job; and it contained, withal, much fun;--at least, for Lad. But, pigs were different. Experience and instinct had taught Lad what few humans realize. Namely, that of all created beasts, the pig is the worst and meanest and most vicious; and hardest to drive. When a horse or a cow, or a drove of them, wandered into the confines of the Place, it was simple and joyous to head them off, turn them, set them into a gallop and send them on their journey at top speed. It took little skill and less trouble to do this. Besides, it was gorgeous sport. But pigs--! When a porker wriggled and hunched and nosed a space in the line fence, and slithered greasily through, Lad's work was cut out for him. It looked simple enough. But it was not simple. Nor was it safe. In the first instance, pigs were hard to start running. Oftener than not they would stand, braced, and glare at the oncoming collie from out their evil little red-rimmed eyes; the snouts above the hideous masked tushes quivering avidly. That meant Lad must circle them, at whirlwind speed; barking a thunderous fanfare to confuse them; and watching his chance to flash in and nip ear or flank; or otherwise get the brutes to running. And, even on the run, they had an ugly way of wheeling, at close quarters, to face the pursuer. The razor tushes and the pronged forefeet were always ready, at such times, to wreak death on the dog, unless he should have the wit and the skill and the speed to change, in a breath, the direction of his dash. No, pigs were not pleasant trespassers. There was no fun in routing them. And there was real danger. Except by dint of swiftness and of brain; an eighty-pound collie has no chance against a six-hundred-pound pig. The pig's hide, for one thing, is too thick to pierce with an average slash or nip: And the pig is too close to earth and too well-balanced by build and weight, to be overturned: And the tushes and forefeet can move with deceptive quickness. Also, back of the red-rimmed little eyes flickers the redder spirit of murder.
