[Genealib] WW I query

[Hayes, Alice]

I have a patron who is stumped by notes she has found regarding an individual who was in the army preceding WWI.  This individual enlisted in the Army on October 24, 1914 and was in the service for some 5 years. 
 
Two separate notes that she has found regarding his enlistment record have notations that are similar (she assumes they were copied from the same document) but she cannot decipher exactly what is written (because of the script) nor can she interpret what the notation means.
 
The first notation reads:  Left US for P T (or J--this is where the script confuses her) 12/5/1914 
 
The second notation reads:  Arrived US from P T (or J) 10/8/1917
 
She knows that he was in France from 1918-1919 and was eventually discharged in June 1920.  Her question is: What is the destination between 1914  and 1917.  
 
Any help on this would be appreciated.  Thank you.
