twelve o'clock
The river was high , the current much stronger than it had been in the Wisconsin , and the progress of the raft was correspondingly increased . I met a steamboat struggling against the stream , and passed quite near to her . The swell that she left behind her caused the raft to roll heavily for a moment ; but it did not disturb the sleepers in the house . I called Sim at twelve o'clock , as nearly as I could judge , and he faithfully promised me that he would keep awake till daylight . I left him alone on the platform , and turned in , though not without some doubts in regard to his ability to be true to his promise . I went to sleep very promptly , and I must do Sim the justice to say that I found the raft all right when he called me at sunrise , an hour later than the time agreed upon . He told me that nothing had happened during the night , except that a steamboat had nearly upset the raft .
