How could I doubt it? It had veered slightly and swung back into a straight-line course again, and if I'd tried to drag myself out of its path there was room enough for it to veer again before I could hope to save myself.
It takes several seconds to recover from a scare like that, even when the danger evaporates right before your eyes. All at once the tractor was veering again, but far enough to the left to make me feel certain that I wouldn't be flattened to a pancake if I stayed where I was. But you can feel certain about something like that and go right on remembering what big tractors have done at various times in the past to men unfortunate enough to be caught off guard when there's a killer in the driver's seat.
The vehicle came to a jolting, grinding halt a few yards to the left of me, and the driver swung himself out of the glass-shielded front seat, descended lightly to the ground, and was grabbing me by the arm and helping me to rise before I could get a really good look at him.
He'd descended from the tractor lightly because he was that kind of a man—just about the most fragile-looking guy I'd ever seen. He was lean to the point of emaciation, with gaunt cheeks and sparse white hair that was fluffed out like thistledown by the wind that was blowing across the square.
He had deepset brown eyes, very sharp and piercing and they were glowing now with a kind of feverish brightness, as if his agitation matched my own or had reached a peak that was just a trifle higher. There was nothing surprising about that, if he knew exactly what had happened and it was as bad as I feared it might be.
Despite his frailness, he had the features of a strong-willed man, the chin and mouth firm, the nose pinched a little at the nostrils, as if stubbornness in adversity had become an ingrained habit with him. I had the feeling I'd seen that face before, but I couldn't remember where or under what circumstances.
I was certainly seeing it now under the most nerve-shattering of all circumstances and would not be likely to forget it a second time.
"How are you, all right?" he asked, his eyes searching my face as if he was far from sure I knew myself and the way I looked would tell him more than just a guess on my part. "That explosion was miles from here," he went on breathlessly, "but it lifted the tractor right off the ground, treads and all, for a second. I had the craziest kind of floating sensation until it settled down and kept right on in this direction. I increased the speed, because I sort of felt that a fast-moving machine would have a better chance of not overturning."
I stared at him half-dazedly, feeling like a pawn on a chessboard that had tilted just far enough to make me wonder if it might not still be precariously poised and go crashing at any moment. And since I couldn't see the players I didn't know what the rules of that particular game were or how far they had been abrogated.
"How do you feel?" he asked.
