Her inability to hear continued to increase by slow degrees during the next six years; and when she was eighteen "a sort of accident" suddenly increased it. Music had, until then, been one of her great delights, and it shows how gradual was the progress of her deafness, that she found herself able to hear at an orchestral concert, provided she could get a seat with a back against which she could press her shoulder-blades, for a long time after the music had become inaudible without this assistance. Such a gradual deprivation of a most important sense is surely far more trying than a quick, unexpected, and obviously irremediable loss would be. The alternations of hope and despair, the difficulty of inducing the sufferer's friends to recognize how serious the case is, the perhaps yet greater difficulty to the patient to resolutely step out of the ranks of ordinary people and take up the position of one deficient in a sense, the mortifications which have to be endured again and again both from the ignorance of strangers and the mistaken sympathy of friends--all these make up the special trial of one who becomes by degrees the subject of a chronic affliction. No sensitive person can possibly pass through this fiery trial unchanged. Such an experience must either refine or harden; must either strengthen the powers of endurance or break down the mind to querulous ill-temper; must either make self the centre of creation or greatly add to the power of putting personal interests aside for the sake of wider and more unselfish thoughts and feelings. Which class of influences Harriet Martineau accepted from her trial the history of her courageous, resolute life-work, and her devotion to truth and duty as she saw them, will sufficiently show. How much she suffered in mind was quite unknown to her family at the time. She was always reserved in speaking about her own feelings and emotions to her mother, and in this particular case Mrs. Martineau, with the kindest intentions, discouraged, as far as possible, all recognition of the growing infirmity. The society of Norwich had never been very attractive to the young girl, who was above the average in natural abilities, and still further removed from the petty and frivolous gossip of the commonplace evening party, by the extensive and elevating course of study through which her mind had passed. Had she been well able to hear, she could have quietly accepted what such intercourse could give her. This would have been much. Kindliness and good feeling, common sense, and ideas about man and his circumstances, are to be enjoyed and gained quite as much in ordinary as in what is commonly called intellectual society. But in the freshness of her sensitive suffering Harriet shrank from the Norwich evening parties. Her mother, however, insisted upon her taking her full share of visiting.
