But meanwhile the shadow was deepening over the home at Dunglass. All through the autumn and early winter his father was slowly sinking. He was only fifty-one, but he was already worn out; and his disease, if disease it might be called, had many of the symptoms of extreme old age. His son saw him for the last time near the close of the year. "I cannot say," he wrote to Miss Darling, "that depression of spirits was the only, or even the chief, emotion with which I bade farewell to my father. There was something so touching in his patience and resignation, so calm and inwrought in his meek submission to the Divine will, that it affected me more strongly than raptures of religious joy could have done. He displays the same evenness of temper in the sight of death as has marked his equable and consistent life." He died in the early morning of 3rd January 1841. His son William thus describes the scene: "It was the first time any of us except our mother had looked on the face of the dying in the act of departing, and that leaves an impression that can never be effaced. When the end came, and each had truly realised what had happened, our mother in a broken voice asked that 'the Books' might be laid on the table; then she gave out that verse in the 107th Psalm-- 'The storm is changed into a calm At his command and will; So that the waves that raged before, Now quiet are and still.' It was her voice, too, that raised the tune. Then she asked Thomas to read a chapter of the Bible and afterwards to pray. We all knelt down, and Thomas made a strong effort to steady his voice, but he failed utterly; then the dear mother herself lifted the voice of thanksgiving for the victory that had been won, and after that the neighbours were called in."[4] Cairns was soon to have further experience of anxiety in respect to the health of those who were near to him. Towards the close of the year in which his father died, his brother William, who had almost completed his apprenticeship to a mason at Chirnside, in Berwickshire, was seized with inflammation, and for some weeks hung between life and death. At length he recovered sufficiently to be removed under his elder brother's careful and loving supervision to the Edinburgh Infirmary, where he remained for four months. During all that time Cairns visited his brother twice every day, he taught himself to apply to the patient the galvanic treatment which had been prescribed, and brought him an endless supply of books, periodicals, and good things to eat and smoke.
