What an amazing thing is the coming of spring to London. The very pavements seem ready to crack and lift under the denied earth; in the air is a consciousness of life which tells you that if traffic stopped for a fortnight grass would grow again in Piccadilly and corn would spring in pavement cracks where a horse had spilt his 'feed'. And the squares of London, so dingy and black since the first October gale, fill week by week with the rising tide of life, just as the sea, running up the creeks and pushing itself forward inch by inch towards the land, comes at last to each remote rock pool.
