I suspect substituing the word "interesting" might solve the riddle.

This DAY BY DAY resource is really a work in progress and I encourage you
to report the errors to the Elmira Center for Mark Twain Studies. A number
of glitches I have found are related to extensive passages underlined --
indicating a link to an outside online resource.  Clcking on and following
those underlined passages (links)  led to some surprising results unrelated
to the passages that had been linked up.
