As fresh coal and iron pits were being opened in the district around Walsall, accidents became more frequent, and it was found impracticable to send those injured to Birmingham, which was seven miles distant; Accordingly, in 1863, the Town Council invited the Redcar Society to start a hospital there. When the Sister who had begun the work fell ill, Sister Dora was sent in her place, and almost directly caught small-pox from the outpatients. She was very ill, and even in her delirium showed the bent of her mind by ripping her sheets into strips to serve as bandages.

When the cottage hospital—which was the second of its kind in England—was opened, the system of voluntary nursing was unknown; the only voluntary nurses heard of then being those who had gone out to the Crimea with Miss Florence Nightingale. Therefore a good deal of misunderstanding was the result; but in the course of time people began to judge the institution by its results. But Sister Dora, by her frank, open manner, disarmed suspicion, while the sublime eloquence of noble deeds silenced tongues, and won for the hospital the confidence of the public, and for herself the admiration and affection of the people.

In 1866 she had a serious illness, brought on by exposure to wet and cold. She would come home from dressing wounds in the cottages, wet through and hot with hurrying along the streets, to find a crowd of outpatients awaiting her return at the hospital, and she would attend to them in total disregard of herself, and allow her wet clothes to dry on her.

This neglect occurred once too often; a chill settled on her, and for three weeks she was dangerously ill. Then it was that the people of Walsall began to realise what she was, and the door of the hospital was besieged by poor people come to inquire how their "Sister Dora" was.

The hospital had moved men of every shade of politics, and every form of religious belief, to the work, and there have been passages in its history not pleasant to remember, but not one of these in the remotest degree involved Sister Dora. On the contrary, her presence and counsel always brought light and peace, and lifted every question into a higher sphere. "Ask Sister Dora," it used to be said. "Had we not better send for Sister Dora" some member would exclaim out of the fog of contention. Thereupon she would appear; and many well remember how calmly self-possessed, and clear-sighted she would stand—never sit down. Indeed, there were those who worked with her fifteen years who never saw her seated; she would stand, usually with her hand on the back of the chair which had been placed for her, every eye directed to her; nor was it ever many moments before she had grasped the whole question, and given her opinion just as clearly and simply and straight to the purpose as any opinion given to the sufferers in the wards. Nor was she ever wrong; nor did she ever fail of her purpose with the committee. No committeemen ever questioned or differed from Sister Dora, yet in her was the charm of unconsciousness of power or superiority and the impression left was of there being no feeling of pleasure in her, other than the triumph of the right.

In 1867 the cottage hospital had to be abandoned, as erysipelas broke out and would not be expelled. The wards were evidently impregnated with malignant germs to such an extent that the committee resolved to build a new hospital in a better situation.

Sister Dora's work became more engrossing when this larger field was opened for it; the men's beds were constantly full, and even the women's ward was hardly ever entirely empty.

Just at this period an epidemic of small-pox broke out in Walsall, and all the energies of Sister Dora were called into play. She visited the cottages where the patients lay, and nursed them or saw to their being supplied with what they needed; whilst at the same time carrying on her usual work at the hospital.

One night she was sent for by a poor man who was dying of what she called "black-pox," a violent form of small-pox. She went at once, and found him in the last extremity. All his relations had fled, and a neighbour alone was with him. When Sister Dora found that only one small piece of candle was left in the house, she gave the woman some money, begging her to go and buy some means of light whilst she stayed with the man. She sat on by his bed, but the woman, who had probably spent the money at the public house, never returned; and after some little while the dying man raised himself up in bed with a last effort, saying, "Sister, kiss me before I die." She took him, all covered as he was with the loathsome disease, into her arms and kissed him, the candle going out almost as she did so, leaving them in total darkness. He implored her not to leave him while he lived, although he might have known she would never do that. So she sat through the night, till the early dawn breaking in revealed that the man was dead.

When the bell at the head of her bed rang at night she rose at once, saying to herself, "The Master is come, and calleth for thee!" Indeed, she loved to think that she was ministering to her Lord in the person of His poor and sick.
