"a reporter from the Sioux City Journal called at his room at the Hubbard House"
"Wilde spoke on March 20th at the Academy of Music"
L&S's account is interspersed with verbatim quotes taken from the Sioux City Journal [1,2], and the references to Wilde's lecture venue and accommodation clearly read as taken from the same source. Thus the verification can be deemed as the reporting of a primary source.
 The Journal of March 20 reported Wilde in interview as follows:
"His demeanor is ladylike. He occasionally moistened his wrists in a preoccupied way with perfume from a tiny flat vial. His large, liquid eyes rolled upwards at times as he became interested, something as a schoolgirl's when she speaks to an intimate friend of her latest love affair."
 The Journal of March 21 reported Wilde's lecture as follows:
"spiritless namby-pamby nondescript"
"a caricature on robust manhood"
It can be concluded that for one midwest newspaper at least, Wilde's effete manner, whether natural or affected, was approximately a century ahead of its time.
