ten o'clock
Mr. Carnegie 's word , in that house , was law . The next morning Mr. Carnegie was not in imperative haste to start on his daily circuit . The boys had to give him an account of yesterday 's fun . He heard them comfortably , and rejoiced the heart of Bessie by telling her to be ready to ride with him at ten o'clock -- her mother could spare her . Bessie was not to wait for when the hour came . These rides with her father were ever her chief delight . She wore a round beaver hat with a rosette in front , and a habit of dark blue serge .
