It  may  be  asked  with  pertinence  how  a  man
could  travel  in  the  interest  of  one  line  and
yet  be  in  possession  of  so  much  information
relating  to  every  other  line;  or  how  one  could
master  the  intricacies  of  foreign  banking  and

  experience  in  medicine,  a  profession
which  developed  a  naturally  analytical  mind,
so  that  he  looked  at  things  with  the  eyes  of  a
student  and  from  the  viewpoint  of  the  trained
diagnostician.  For  six  years  he  followed
medicine  in  Latin  America,  finally  giving  it
up  to  accept  an  offer  from  a  large  company
