"I confess that I never think of London, which I love, without thinking of that palace which David built for Bathsheba, sitting in hearing of one hundred streams,—streams of thought, of intelligence, of activity. One other thing about London impresses me beyond any other sound I have ever heard, and that is the low, unceasing roar one hears always in the air; it is not a mere accident, like a tempest or a cataract, but it is impressive, because it always indicates human will, and impulse, and conscious movement; and I confess that when I hear it I almost feel as if I were listening to the roaring loom of time.
