The following extract from a letter written by Mr. Brontë a few years later, in reference to scientific knowledge, is sufficiently characteristic. He says: 'In this age of innovation and scepticism, it is the incumbent duty of every man of an enlarged and pious mind to promote, to the utmost extent of his abilities, every movement in the variegated, complex system of human affairs, which may have either a direct, indirect, or collateral tendency to purify and expand the naturally polluted and circumscribed mind of fallen nature, and to raise it to that elevation which the Scriptures require, as well as the best interests of humanity.' Upon the death of his wife, Mr. Brontë felt the need of some one to superintend the affairs of his household, and assist him in this important charge of the bringing-up of his children; and so, towards the end of the year 1822, an elder sister of the deceased lady, Miss Elizabeth Branwell of Penzance, came to reside with him. She is represented to have been, in personal appearance, of low and slight proportions; prim and starched in her attire, which was, when prepared for the reception of visitors, invariably of silk; and she wore, according to the fashion of the time, a frontal of auburn curls, gracefully overshadowing her forehead. She took occasionally, through habit, a pinch from her gold snuff-box, which she had always at hand. When she had taken up her residence at bleak, wild, and barren Haworth, she is said to have sighed for the flower-decked meads of sunny Penzance, her native place. Miss Branwell's affectionate regard for her dead sister's children caused her to take deep interest in everything relating to them, their health, the comfort and cleanliness of their home, and the sedulous culture of their minds. In the management of Mr. Brontë's household she was materially assisted by the faithful and trustworthy Tabby, who, in 1825, was added to the family as a domestic servant. By a long and faithful service of some thirty years in the Brontë family, Tabby gained the respect and confidence of the household. She had been born and nurtured in the chapelry of Haworth, at a time when mills and machinery were not, when railways had not made the inhabitants of the hills and valleys familiar with the cities and towns of England; and, moreover, before the ancient dialect, so interesting philologically to the readers of King Alfred's translations of Orosius and Bede, and the like, came to be considered rude, vulgar, and barbarous. Tabby used the dialect rightly, without any attempt to improve on the language of her childhood and of her fathers; and she was original and truthful in this, as in all her ways. It was from Tabby, principally, that the youthful Brontës gained the familiarity with the Yorkshire Doric, which they afterwards reproduced with such accuracy in 'Shirley,' 'Wuthering Heights,' and others of their writings.
