William Carlos Williams - Young Sycamore

I must tell you
this young tree
whose round and firm trunk
between the wet

pavement and the gutter
(where water
is trickling) rises
bodily

into the air with
one undulant
thrust half its height-
and then

dividing and waning
sending out
young branches on
all sides-

hung with cocoons
it thins
till nothing is left of it
but two

eccentric knotted
twigs
bending forward
hornlike at the top

William Carlos Williams
