Sundays were lonely.

During the rest of the week there was work — physical labor — for a man to do, the endless, trudging round of work that is necessary to extract a living from the soil. Land to plow, crops to be put in and tended and finally harvested, wood to cut, fences to be built and mended, machines to be repaired — things that must be done with bone and muscle, with calloused hand and aching back and the hot sun on one's neck or the whiplash of windy cold biting at one's bones.

For six days a farmer labored and the labor was a thing that dulled one to the aching emptiness of memory and at night, when work was done, sleep was swift and merciful. There were times when the work, not only for its sedative effect but of its very self, became a thing of interest and of satisfaction. The straight line of new-set fence posts became a minor triumph when one glanced back along their length. The harvest field, with its dust upon one's hoes and its smell of sun on golden straw and the clacking of the binder as it went its rounds, became a full-breasted symbolism of plenty and contentment. And there were moments when the pink blush of apple blossoms shining through the silver rain of spring became a wild and pagan paean of the resurrection of the Earth from the frosts of winter.

For six days a man would labor and would not have time to think; on the seventh day he rested and braced himself for the loneliness and the thoughts of desperation that idleness would bring.

Not a loneliness for a people or a world or a way of life, for this world was kindlier and closer to Earth and life and safer — much safer — than the world one had left behind. But a nagging loneliness, an accusing loneliness that talked of a job that waited, a piece of work that now might wait forever, a task that must be done, but now might never be done.

At first there had been hope.

Surely, Sutton thought, they will look for me. Surely they will find a way to reach me.

The thought was a comfort that he hugged close against himself, a peace of mind that he could not bring himself to analyze too closely. For he realized, even as he coddled it, that it was a generalization, that it might not survive too close a scrutiny, that it was fashioned of faith and of wishful thinking and that for all its wealth of comfort it might be a fragile bauble.

The past cannot be changed, he argued with himself, in its entirety. It can be altered — subtly. It can be twisted and it can be dented and it can be whittled down, but by and large it stands. And that is why I'm here, that must be why I'm here, and I'll have to stay until old John H. writes the letter to himself. For the past is in the letter — the letter brought me here and it will keep me here until it's finally written. Up to that point the pattern must necessarily hold, for up to that point in time the past, so far as I and my relation with it are concerned, is a known and revealed past. But the moment the letter is written it becomes an unknown past, it tends to the speculative and there is no known pattern. After the letter's written, so far as I'm concerned anything can happen.

Although he admitted, even as he thought it, that his premise was fallacious. For known or not, revealed or unrevealed, the past would form a pattern. For the past had happened. He was living in a time that already had been set and molded.
