"all but blind" by walter de la mare

"all but blind
in his chambered hole
groped for worms
the four-clawed mole.

all but blind
in the evening sky,
the hooded bat
twirls softly by.

all but blind
in the burning day
the barn-owl blunders
on her way.

and blind as are
these three to me,
so, blind to someone
i must be."
