In Brussels, Emily was homesick as ever, the suffering and conflict being heightened, in the words of Charlotte, "by the strong recoil of her upright, heretic, and English spirit from the gentle Jesuitry of the foreign and Romish system. She was never happy till she carried her hard-won knowledge back to the remote English village, the old parsonage house, and desolate Yorkshire hills." "We are completely isolated in the midst of numbers. Yet I think I am never unhappy; my present life is so delightful, so congenial to my own nature, compared with that of a governess," was Charlotte's further description.
The sisters were so successful with their study of French that Madame Héger proposed that both should stay another half year, Charlotte to teach English, and Emily music; but from Brussels the girls were brought hastily home by the illness and death of their aunt, who left to each of them independently a share of her savings--enough to enable them to make whatever alterations were needed to turn the parsonage into a school. Emily now stayed at home, and Charlotte (January, 1843) returned to Brussels to teach English to Belgian pupils, under a constant sense of solitude and depression, while she learned German. A year later she returned to Haworth, on receiving news of the distressing conduct of her brother Branwell and the rapid failure of her father's sight. On leaving Brussels, she took with her a diploma certifying that she was perfectly capable of teaching the French language, and her pupils showed for her, at parting, an affection which she observed with grateful surprise.
The attempt to secure pupils at Haworth failed. At this time the conduct of the now dissipated brother Branwell--conduct bordering on insanity--caused the family the most terrible anxiety; their father was nearly blind with cataract, and Charlotte herself lived under the dread of blindness. It was now that she paid a visit to her friends the Nusseys, at Hathersage, in Derbyshire, the scene of the later chapters of "Jane Eyre." On her return she found her brother dismissed from his employment, a slave to opium, and to drink whenever he could get it, and for some time before he died he had attacks of delirium tremens of the most frightful character.
