'Of the extent and value of Miller's original contributions to geology I am, perhaps, hardly fitted to speak. He was one of my earliest and kindest scientific friends. He used to relate to me the results of his summer rambles before he had time to set them down in writing. He admitted me into the intimacy of his inner thoughts on geological questions and controversies. He brought me completely under the spell of his personal charm, and filled me with an enthusiastic love for the man as well as a passionate admiration for the geologist. Nor has the glamour of that early friendship passed away. I would rather leave to others the invidious task of coldly dissecting Hugh Miller's work and seeing how much of it has been a permanent addition to science, and how much has passed away with the crudities of advancing knowledge. I will only say that there cannot be any doubt that his contributions to the stock of geological fact were much less important than the influence which his writings ever had in furthering the spread of an appreciation of geological science throughout the English-speaking world. 'There were two departments in which his best original work was done. One of these was the Old Red Sandstone, where he laid the foundations of his fame as an observer and describer of Nature. His unwearied devotion to the task of collecting the fishes of the Old Red Sandstone, and his patient industry in piecing their broken fragments together, opened up a new chapter in the history of Life on our globe. The other department was that which embraces the story of the Ice Age. Miller was one of the pioneers in the study of the Boulder-Clay. The last years of his life were more especially devoted to that interesting formation in which he found fossil shells in many parts of Scotland where they had never been found before. I well remember my last interview with him, only a few evenings before his death. He had spent a short holiday in the low ground about Bucklyvie between the Forth and Clyde, and had collected a number of marine shells, which led him to draw a graphic picture of what must have been the condition of central Scotland during a part of the glacial period. On the same occasion he questioned me as usual about my own geological doings. I had been surveying in detail the geological structure of Arthur's Seat at Edinburgh, and showed him my maps. He went over them with lively comments, and, when he had done, turned round to his eldest daughter, then a girl at school, and gave her in his own pictorial way a sketch of the history of the volcano that had piled up the picturesque hill on the eastern outskirts of the city.
