The news of a second pregnancy had thrilled both parents: a three-year gap was a worry. Now they would have that boy!

“It is a boy,” said Peg positively as her belly swelled. “I am carrying this one differently.”

The smallpox broke out. Time out of mind, every generation had lived with it; like the plague, its mortality rate had slowly waned, so that only the most severe epidemics killed many. The faces one saw in the streets often bore the disfiguring craters of pock marks-a shame, but at least the life had been spared. Dick Morgan’s face was slightly pock marked, but Mag and Peg had had the cowpox as girls, and never succumbed. Country superstition said that the cowpox meant no smallpox. So as soon as Richard had turned five, Mag took him to her father’s farm near Bedminster during a spate of the disease and made the little fellow try to milk cows until he came down with this benign, protective sort of pox.

Richard and Peg had fully intended to do the same with Mary, but no cowpox appeared in Bedminster. Not yet four, the child had suddenly burned with terrible fever, moaned and twisted her pain-racked body, cried in a constant frenzy for her dadda. When Cousin James-the-druggist came (the Morgans knew he was a better doctor than any in Bristol who called themselves doctors) he looked grave.

“If the fever comes down when the spots appear, she will live,” he said. “There are no medicaments can alter God’s will. Keep her warm and do not let the air get at her.”

Richard tried to help nurse her, sitting hour after hour beside the cot he had made and artfully fitted up with gimbals so that it swayed gently without the grind of cradle rockers. On the fourth day after the fever began the spots appeared, livid areolae with what looked like lead shot in their centers. Face, lower arms and hands, lower legs and feet. Vile, horrific. He talked to her and crooned to her, held her plucking hands while Peg and Mag changed her linens, washed her shrunken little buttocks as wrinkled and juiceless as an old woman’s. But the fever did not diminish, and eventually, as the pustules burst and cratered, she flickered out as softly and subtly as a candle.
