four o'clock at night
CRACOW , 26 June . Sniatynski has arrived . He has promised to do it , -- good fellow , God bless him for it ! It is four o'clock at night , but I can not sleep , so I sit down to write , for I can do nothing else . We talked together , discussed and quarrelled till three o'clock . Now he is sleeping in the adjoining room . I could not at first persuade him to undertake the mission .
