Charlotte Brontë had been a star pupil at Roe Head in 1831-32, and a teacher with Miss Wooler since 1835. Among the pupils were her two younger sisters, Emily and Anne.
According to Charlotte Brontë's biographer, Elizabeth Gaskell, the change was not for the better:
"About this time Miss Wooler removed her school from the fine, open, breezy situation of Roe Head, to Dewsbury Moor, only two or three miles distant. Her new residence was a much lower site, and the air much less pure and exhilarating to one bred at the wild hill-village of Haworth. Charlotte felt the change extremely, and regretted it not merely on her own account, but for the sake of her sister Anne. ...[Charlotte] bent her whole energy towards the fulfilment of the duties in hand; but her occupation was not sufficient food for her great forces of intellect, and they cried out perpetually, "Give, give," while the flat and comparatively stagnant air of Dewsbury Moor told upon her health and spirits more and more. ...
She had another weight on her mind this Christmas . I have said that Dewsbury Moor was low and damp, and that the air did not agree with her, though she herself was hardly aware how much her life there was affecting her health. But Anne had begun to suffer just before the holidays, and Charlotte watched over her younger sisters with the jealous vigilance of some wild creature, that changes her very nature if danger threatens her young. Anne had a slight cough, a pain at her side, a difficulty of breathing. Miss Wooler considered it as little more than a common cold; but Charlotte felt every indication of incipient consumption as a stab at her heart, remembering Maria and Elizabeth, whose places once knew them, and should know them no more.
Stung by anxiety for this little sister, she upbraided Miss Wooler for her fancied indifference to Anne's state of health. Miss Wooler felt these reproaches keenly, and wrote to Mr. Bronte about them. He immediately sent for his children, who left Dewsbury Moor the next day. Meanwhile, Charlotte had resolved that Anne should never return as a pupil, nor she herself as a governess. But, just before she left, Miss Wooler sought for the opportunity of an explanation of each other's words, and the issue proved that "the falling out of faithful friends, renewing is of love." And so ended the first, last; and only difference Charlotte ever had with "good and kind Miss Wooler".
