By September all the vegetation was fast crumbling to a greyish powder, and Nahum feared that the trees would die before the poison was out of the soil. His wife now had spells of terrific screaming, and he and the boys were in a constant state of nervous tension. They shunned people now, and when school opened the boys did not go. But it was Ammi, on one of his rare visits, who first realized that the well water was no longer good. It had an evil taste that was not exactly fetid nor exactly salty, and Ammi advised his friend to dig another well on higher ground to use till the soil was good again. Nahum, however, ignored the warning, for he had by that time become calloused to strange and unpleasant things. He and the boys continued to use the tainted supply, drinking it as listlessly and mechanically as they ate their meagre and ill-cooked meals and did their thankless and monotonous chores through the aimless days. There was something of stolid resignation about them all, as if they walked half in another world between lines of nameless guards to a certain and familiar doom.
