When Morrison was at work at his father's business he was employed at manual labour for twelve or fourteen hours a day; yet he seldom omitted to find time for one or two hours of reading and meditation. He read and re-read frequently those few books he was able to obtain. The diary, which he began to keep very early in his life, shows that he did much self-introspection; his earnestness was clearly intense, and his sense of his own shortcomings continued to be remarkably vivid.
