Read the lines from "The Seeds of Love from Six Plays" by Florence Henrietta Darwin.

The time is Midsummer
Act I (excerpt)
Woodland road outside MARY's cottage... Bunches of leaves and herbs hang drying around door and window. MARY is heard singing within.

MARY [Singing]
"I sowed the seeds of Love,
And I sowed them in the Spring.
I gathered them up in the morning so soon.
While the sweet birds so sweetly sing.
While the sweet birds so sweetly sing..."

During the singing, LUBIN comes slowly and heavily along the road. He wears the dress of a farm laborer and carries a scythe over his shoulder.

MARY [Coming to the doorway with more plants and singing]
ISABEL: "O 'twas such beautiful times as we did have down by the riverside, him and me."
LUBIN: "She would sit, her hand in mine by the hour of a Sunday afternoon."

[A pause during which LUBIN and ISABEL seem lost in their own sad memories...]

ISABEL: "And when I heard as 'twas to-morrow they were to wed, though 'twas like driving a knife deeper within the heart of me, I up and got me upon the road and did travel along by starlight and dawn and day just for one look upon his face again."
LUBIN: "'Twas so with me. From beyond Oxford town I am come to hurt myself worse than ever, by one sight of the eyes that have looked so cruel false into mine."
