It was so hard to find out what humans would enjoy and what they wouldn't!

CHAPTER X. The Intruders

It began with a gap in a line fence. The gap should never have been there. For, on the far side of it roamed creatures whose chief zest in life is the finding of such gaps and in breaking through for forage.

The Place's acreage ended, to northward, in the center of an oak grove whose northern half was owned by one Titus Romaine; a crabbed little farmer of the old school. Into his half of the grove, in autumn when mast lay thick and rich amid the tawny dead leaves, Romaine was wont to turn his herd of swine.

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.

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—!
