Unlike the human lice, the house-fly—not having irrevocably linked its destiny with man’s—had suffered nothing that approached annihilation. Like the house rat, the house mouse, the human flea, and the cockroach, this other intimate household companion had suffered only a considerable reverse. Where formerly it had buzzed by hundreds and thousands, now it was reduced to its twenties or tens. Nevertheless, it survived.
For, like that lord whom Price Hamlet calls a “water-fly,” the house-fly also was secure in “the possession of dirt,” though for it
dirt must mean, not lands and estates, but the word in its dysphemistic sense, as when the Bible of King James declares primly that Ehud struck King Eglon in the belly, “and the dirt came out.” Thus, even though man should be reduced to the vanishing point or disappear altogether, the house-fly was secure as long as the larger animals still lived and continued to leave droppings behind them. The eggs of the fly, thus deposited, soon hatched out, and the larvae found themselves embowered in rich and succulent food on which to feast, as snakes upon rats, woodpeckers upon grubs, and men on the flesh of dead animals.Still, with man eclipsed, times were hard. No longer did barnyards offer sites as rich as the ancient gift of the Nile, no longer was the countryside studded with beneficently unscreened privies, no longer did innumerable slums offer their choice piles of garbage and filth. Only here and there some few accumulations of nourishing excrement permitted the house-fly to lay numerous eggs and breed up well-fostered larvae and send forth vigorous and busily traveling adults.
A week later the epidemic was in full course. Dick, Bob’s companion on the expedition, had been the next to go down. But now Ezra and five of the children lay stricken. In proportion to its numbers, the community was in the grip of a devastating outbreak of what must be—Ish felt certain—typhoid fever.
Some of the adults had been inoculated in the Old Times, but their immunity must long since have lapsed. All the children were totally unguarded. Even with all the old-time medical skill typhoid had been combatted chiefly by prevention. Once the disease was established, there was no remedy but to let it run its long and sinister course.
Easy enough now, thought Ish, to do some second thinking! Easy enough, he thought bitterly, to know that Charlie, no matter what other diseases he might have had or thought he had, was really carrying the germs from an attack of typhoid fever! Perhaps he had been sick years before; perhaps he had been sick recently, for quite possibly the disease had made the passage in the area where he had lived. They would never know. And now, what did it matter?
What they knew for certain was that Charlie, obviously unclean in personal habits, had eaten with the two boys for more than a week. In addition, the not too carefully constructed outhouses and the flies offered an obvious route of general infection.
