There is something at work in my soul which I do not understand. I am practically industrious - painstaking, a workman to execute with perseverance and labour - but besides this there is a love for the marvellous, a belief in the marvellous, intertwined in all my projects, which hurries me out of the common pathways of men, even to the wild sea and unvisited regions I am about to explore.
