Read it through once

Esther left a dozen stamps with her, and soon after she began to receive letters containing the addresses of ladies who required servants. They were of all sorts, for the secretary seemed to exercise hardly any discrimination, and Esther was sent on long journeys from Brixton to Notting Hill to visit poor people who could hardly afford a maid-of-all-work. These useless journeys were very fatiguing. Sometimes she was asked to call at a house in Bayswater, and thence she had to go to High Street, Kensington, or Earl's Court; a third address might be in Chelsea. She could only guess which was the best chance, and while she was hesitating the situation might be given away. Very often the ladies were out, and she was asked to call later in the day. These casual hours she spent in the parks, mending Jackie's socks or hemming pocket handkerchiefs, so she was frequently delayed till evening; and in the mildness of the summer twilight, with some fresh disappointment lying heavy on her heart, she made her way from the Marble Arch round the barren Serpentine into Piccadilly, with its stream of light beginning in the sunset.
