four o'clock
Occasionally Mrs. Field looked over at them , thought of her Lois , and noted their merriment gravely . She never dreamed that they were laughing at her . If she had , she would not have considered it twice . It was four o'clock when Mrs. Field arrived in Boston . She had been in the city but once before , when she was a young girl . Still she set out with no hesitation to walk across the city to the depot where she must take the cars for Elliot . She could not afford a carriage , and she would not trust herself in a street car .
