Earth Abides

He stood on the porch again. Minute by minute the long ch i of street-lights grew less and less luminous, more and more yellow. The high wind, he thought, must be helping, blowing down a power-line here, weakening a switch connection there. The fire too was sweeping across the forested ridges unchecked by men, burning power-lines, perhaps, even power-houses.

After a while the lights seemed to fade no further, but to remain at a constant dimness. He went in again, and pulling another bridge-lamp to the side of his chair, he was able to read comfortably with two lights instead of one. Princess lay down again to doze. By now it was late, but he did not want to go to sleep. He felt as if he were sitting up by the deathbed of his most treasured and oldest friend. He remembered those great words “Let there be light, and there was light!” This seemed the other end of that story.

After a while he went to look at the clock again, and saw that it had stopped with the hands symmetrically upward-at eleven-five.

His watch showed him that by now it was well after midnight. The lights might still continue many hours, or even might burn dimly for days. Yet he did not want to go to bed.

He tried to read again, but finally slipped off to sleep in the easy-chair where he was sitting.

With Power-and-Light it was all so carefully contrived that even in the disaster there was no need for adjustment. The men fell sick, but the generators still sent out along the wires their finely timed pulsations. So, when the brief agony of mankind was ended, the lights still burned.

So it continued through the weeks. If a wire broke and cut out a whole town from the flow of power, the system adjusted before that wire had had time to fall to the ground. If a power-house failed, just as quickly the other power-houses in the system stretching across hundreds of miles took up the stack, and sent out more power to fulfill the need.

Yet in any system, as in a chain or a road, there is always a weakest link. (That is the fatal flaw of all systems.) The water would continue to flow; the great generators could spin upon their oil-bathed bearings for years. But the flaw lay in the governors which controlled the generators. No one had ever bothered to make them wholly automatic. Once every ten days they were inspected for oil; once a month, perhaps, there was need to add oil to them. After two months without care the oil supplies grew low, and one by one, as the weeks passed, the governors began to go out of action. When one failed, automatically the great water-nozzle changed angle and the water flowed through without touching the wheel. Then the generator ceased revolving, and sent out no more power. As generator after generator was thus cut out of the system, the strain upon the few remaining ones became greater and greater and the decline of the system became cumulative.

When he awoke, he noticed that the lights had faded still more. The filaments in the electric lamps were only an orange-red now. He could look at them without hurting his eyes. Now, although he had not turned off any of the lamps, the room was in half-darkness.
