There was a very good reason for this, and Ed was it.
All night and day after he shot the stinging unit and the carrier unit, the Harn had stayed in its nest. By the second evening, it was getting hungry. It ventured out and found a few morsels, but the organized hunting network it ordinarily maintained had been disrupted, it had lost track of things, and the pickings were poor. Then it stumbled on the rabbit Ed had staked out.
Its first impulse was to leave the rabbit strictly alone. In spite of its early promise, the other world had so far given nothing but trouble. On the other hand, the rabbit was meat, and very good meat, by the smell and looks of it....
The Harn kept its observation unit prowling irresolutely around the target for half the night before it finally gave in to appetite and sent in a stinger to finish the rabbit off, a carrier to pick it up.
It was still uneasy about this when it noticed Ed near the nest the next morning, confirming its fears. It promptly broke up the net it had been re-establishing and pulled all units back in. Maybe if it left him strictly alone, he might still go on about his business, whatever that was, and let the Harn get back to its harvesting.
By noon, Ed was getting pretty stiff sitting in the tree. He climbed down and eased over toward the stump, watching where he set his feet. He was pretty sure the snakeproof pants would stop the stingers, but he saw no point in putting them to the test until he had to.
About fifty yards away, he got a good view, and it did look like there might be a sizable hole under the stump. He studied it carefully with the glasses. There was a smooth-beaten mound in front, and exposed roots were worn slick.
As he got closer, he noticed an unpleasant smell, and near the mouth of the den he got a sudden whiff that almost gagged him—a sour, acid, carrion stink like a buzzard's nest. He moved back a little. The hole was wide and fairly high, two or three feet, but too dark to see back into. Still, he had a sense of something stirring there not too far back.
