No great harm resulted. The section of pipe was set into place by the workmen, and fiinctioned without difficulty. Shortly before the Great Disaster, a foreman had noticed that this section had developed a slight leak. By the welding of a patch upon it, however, it would be made as good as new, or even stronger than the average.
Then through the years no man passed that way again. A little trickle of water from the faulty section of pipe grew very gradually larger. Even in the dry summers a small patch Of green showed by the dripping pipe; birds and small animals came there to drink. And still rust ate from the outside, and from the inside the corrosive action of the water itself slowly bored outward to meet the rust pits, piercing pinprick after pinprick in the tough skin of steel.
Five years, ten years-now a dozen jets of fine spray played from the surface of the pipe. Now the puddle was a drinking-place for cattle.
In five more years a little stream ran off from beneath, the only summer stream in all that dry foothill region. By now the pipe was beginning to be honey-combed with rust, its actual structure grown weak.
Beneath the pipe the ground had long been soft and muddy, and the tramping of animals had aided the erosion of a little gully. Finally, the erosion was sufficient to start a mudflow in the soft wet soil on which the concrete pier rested, the one which supported the pipe with its heavy load of water. As the pier settled, the weight of the water was thrown upon the weakened pipe. A long rent opened in its rust-riddled steel, and a broad stream of water poured out and gushed down into the gully. This torrent soon undermined thefooting still more, and it shifted again. Once more the pipe tore, and the stream of water issuing from it became like a small river.
Just as Ish had crawled into bed that evening the sharp crack of a rifle shot brought him sitting full upright, tense. Another resounded, and then a fusillade began popping in the night.
He felt the bed shaking gently, as Em laughed quietly beside him. He relaxed. “Same old trick!” he said.
“Fooled you badly this time!”
“I’ve been thinking too much about all the future today, I suppose. Yes, I suppose my nerves are stirred up a little too much today.”
The fusillade was still popping in a good imitation of guerrilla warfare, but he lay down and tried to relax. He knew now what had happened. After everyone had left the bonfire, one of the boys had sneaked back and thrown a few boxes of cartridges into the hot ashes. As soon as the boxes were burned through and things became hot enough, the cartridges had let loose. Like most practical jokes it involved a certain element of risk, but at this time of year the grass was green, and there was no danger of starting a fire. Also, most of the people had been warned in advance or knew what was likely to happen and so would be sure to keep a long way from the hot ashes. Indeed, Ish reconsidered, he himself might have been the particular object of this joke, and everyone else might have known about it.
