After a while, sitting there, Ed began to feel uneasy. The timber was big here, and open underneath, almost parklike. The nearest cover was fifty or sixty yards off to his left, a little tangle of brush where a tree had fallen and let a shaft of sunlight through. It looked possible, but it didn't feel quite right. Still, it was about the only place anything big enough to bother him could hide. The feeling was getting stronger, the back hairs on Ed's neck were starting to stand up now. Without visible movement, or even noticing himself that he was doing it, he let awareness run over his body, checking the position and stiffness of his legs--he had been sitting there quite a while--the balance of the gun across his knees, the nearness of his thumb to the hammer. Thoughtfully, still studying the patch of brush, he spat a thin stream over his left shoulder at a pile of leaves a few feet away. Thinking about it later, Ed could almost have sworn the tobacco juice sizzled as it hit. Actually, this was probably imaginary. The stinging unit was not that sensitive to tobacco, though it was sensitive enough. As the drops splattered it, the pile of leaves erupted with a snuffling hiss like an overloaded teakettle into a tornado of bucking, twisting activity. Ed's reflexes were not quite as fast as they had been when he was young, but they were better educated. Also, he was already keyed-up. Almost as it started, the flurry in the leaves stopped with the roar of his rifle. Fired like that, the heavy gun just about took his hand off, but he did not notice it at the moment. He came erect in a quick scramble, jacking in a fresh round as he did so. The scene took on that strange timeless aspect it often does in moments of emergency, with a man's whole being focused on the fleeting _now_--you know, in an academic sort of way, that things are moving fast, you are moving fast yourself, but there seems plenty of time to make decisions, to look things over and decide what has to be done, to move precisely, with minimum effort and maximum effect. Whatever the thing at his feet was, it was out of the picture now--it had not even twitched after the heavy bullet tore through it. There was a stomping rush in the little thicket he had been watching. Ed took two long quick steps to one side to clear a couple of trees, threw up the gun and fired as something flashed across a thin spot in the brush. He heard the whack of the bullet in flesh and fired again. Ordinarily he did not like to shoot at things he could not see clearly, but this did not seem the time to be overly finicky. There was no further movement in the brush. He stood there several long moments, listening, and there was no further movement anywhere. He eased the hammer down, fed in three rounds to replace those he had used, and walked slowly back to the first thing he had shot.
