Our summer hearts make summer's fulness, where
No leaf, or bud, or blossom may be seen:
For nature's life in love's deep life doth lie,
Love,--whose           is beauty's death,
Whose mystic key these cells of Thou and I
Into the infinite freedom openeth,
And makes the body's dark and narrow grate
The wide-flung leaves of Heaven's own palace-gate.
