As the cab drew up before the address indicated, the fog lifted a little and showed him a dingy street, a gin palace, a low French eating house, a shop for the retail of penny numbers and twopenny salads, many ragged children huddled in the doorways, and many women of many different nationalities passing out, key in hand, to have a morning glass; and the next moment the fog settled down again upon that part, as brown as umber, and cut him off from his blackguardly surroundings.
The trampled earth of the river-banks and the peaty stain in the pools did not look drab but glowing umber, and the dark woods astir in the breeze did not look, as usual, dim blue with mere depth of distance, but more like wind-tumbled masses of some vivid violet blossom.
