"My
study is a snug little octagonal den, with a coal-grate, 6 big windows,
one little one, & a wide doorway...
The study is nearly on the peak of the hill...In the picture of me in
the study you
glimpse (through the left-hand
window) the little rock bluff that rises behind the pond, and the base
of the little trees on top of it.
The small
square window is over the fireplace; the chimney divides to make room
for it." letter
to John Brown, 9.4.1874,
Elmira, NY, as quoted in Mark
Twain's Letters, Vol. 6
