nine o'clock
Nan and Uncle Henry drove through the snowy streets to another station and took the evening train north . They traveled at first by the Milwaukee Division of the Chicago and Northwestern Railroad ; and now another new experience came Nan 's way . Uncle Henry had secured a section in the sleeping car and each had a berth . It was just like being put to sleep on a shelf , Nan declared , when the porter made up the beds at nine o'clock . She climbed into the upper berth a little later , sure that she would not sleep , and intending to look out of the narrow window to watch the snowy landscape fly by all night . And much to her surprise -LRB- only the surprise came in the morning -RRB- she fell fast asleep almost immediately , lulled by the rocking of the huge car on its springs , and did not arouse until seven o'clock and the car stood on the siding in the big Wisconsin city . They hurried to get a northern bound train and were soon off on what Uncle Henry called the `` longest lap '' of their journey .
