I have seldom gone on a tramp without seeing things that made the heart ache with their beauty or pathos, and other things that set the mind a-tingle with intellectual curiosity. I do not refer to great episodes, but to the little things, unexpected visions of life! Some were unforgettable in themselves and seemed to need no other tablets than those of memory, and yet it was a great addition to inner content and happiness to describe them in my day-book of travels. – Stephen Graham, The Gentle Art of Tramping
