This uncrowned king of finance was called to justify his reign. For three long hours he, now past the scriptural age-limit, faced the inquisitor.

Where two continents had expected a sullen silence or passionate resentment there ensued three hours of suave, goodnatured thrust and parry. .Jove condescended; the Sphinx turned talkative.
