"In evening made a short call to A.M. Warn's".
Well that is it. That is MUST BE when Allen asked Alice's father Andrew (Anders) Magnus Warn for his daughter's hand in marriage. So whenever Alice's out-posting to Chicago took place it was long over with by now. And even the summer separation when she had a job up in Jamestown proved useless. Alice has just come home for a week off and now the mention of the "Short Call". How romantic.
