broken-hearted supplication, I looked a moment at the face I knew so
well; and it was patient with the patience I had so often seen in it:
something of puzzle, a great silent dignity, an assent to what must be
from the depths of a nature whose tragical seriousness broke in the
laughter which the unwise took for the whole of him. Emerson,
Longfellow, Lowell, Holmes--I knew them all and all the rest of our
sages, poets, seers, critics, humorists; they were like one another and
like other literary men; but Clemens was sole, incomparable, the Lincoln
of our literature.
