    M. E. W. Sherwood (1826–1903)

    We used to feel the awe of the distant stars upon us. All that led to was the eighty-eight naval guns, ersatz, and the night air-raids over cities. A magnificent spectacle.
    After the collapse of the socialist dream, I came to America.

    The small perplexities of small minds eddy and boil about you. Confident from the experience that has led you out of these same dangers, you attack each problem as it appears, unafraid.
