profession, or at least one altogether too irregular and undefined. For the next several years, therefore, he attended law classes instead of engineering and science classes in the University, giving to the subject a certain amount of serious, although fitful, attention until he was called to the bar in 1875. So much for the course of Stevenson's outward life during these days at Edinburgh. To tell the story of his inner life would be a far more complicated task, and cannot here be attempted even briefly. The ferment of youth was more acute and more prolonged in him than in most men even of genius. In the Introduction I have tried to give some notion of the many various strains and elements which met in him, and which were in these days pulling one against another in his half-formed being, at a great expense of spirit and body. Add the storms, which from time to time attacked him, of shivering repulsion from the climate and conditions of life in the city which he yet deeply and imaginatively loved; the moods of spiritual revolt against the harsh doctrines of the creed in which he had been brought up, and to which his parents were deeply, his father even passionately, attached; the seasons of temptation, to which he was exposed alike by temperament and circumstance, to seek solace among the crude allurements of the city streets. In the later and maturer correspondence which will appear in these volumes, the agitations of the writer's early days are often enough referred to in retrospect. In the boyish letters to his parents, which make up the chief part of this first section, they naturally find no expression at all; nor will these letters be found to differ much in any way from those of any other lively and observant lad who is also something of a reader and has some natural gift of writing. At the end of the section I have indeed printed one cry of the heart, written not to his parents, but about them, and telling of the strain which matters of religious difference for a while brought into his home relations. The attachment between the father and son from childhood was exceptionally strong. But the father was staunchly wedded to the hereditary creeds and dogmas of Scottish Calvinistic Christianity; while the course of the young man's reading, with the spirit of the generation in which he grew up, had loosed him from the bonds of that theology, and even of dogmatic Christianity in general, and had taught him to respect all creeds alike as expressions of the cravings and conjectures of the human spirit in face of the unsolved mystery of things, rather than to cling to any one of them as a revelation of ultimate truth. The shock to the father was great when his son's opinions came to his knowledge; and there ensued a time of extremely painful discussion and private tension between them. In due time this cloud upon a family life otherwise very harmonious and affectionate passed quite away. But the greater the love, the greater
