At a dangerous turn in the river, a raft loaded with farm animals hits a snag. Several fall off — sheep, pigs, goats, cows — and are swept into the current. The air is filled with heartrending cries. Those still on board jump in the water after them. One, however, a large tan-colored pig with black spots, calmly climbs ashore and starts foraging in someone’s brightly colored vegetable garden. The pig doesn’t notice when the others slip beneath the surface.
