In all the contractions and expansions of that inland sea, the Bay of San Francisco, there can be few drearier scenes than the Vallejo Ferry. Bald shores and a low, bald islet enclose the sea; through the narrows the tide bubbles, muddy like a river. When we made the passage (bound, although yet we knew it not, for Silverado) the steamer jumped, and the black buoys were dancing in the jabble; the ocean breeze blew killing chill; and, although the upper sky was still unflecked with vapour, the sea fogs were pouring in from seaward, over the hilltops of Marin county, in one great, shapeless, silver cloud.
