I'd look thru the volumes of letters and sketches etc. in the months
susurrounding the holidays
and look for any asides or comments Twain wrote to friends and family.
There is on. There is one sketch on
New Years Day he wrote in the mid-1860's, I forget which year.
It's in Vic Doyno's *Writings of an American Skeptic& and
is described in my (*Cradle Skeptic* at the Forum website.
