Versified Reply To An Invitation

Sir,

Yours this moment I unseal,
And faith I’m gay and hearty!
To tell the truth and shame the deil,
I am as fouas Bartie:
ButFoorsday, sir, my promise leal,
Expect me o’your partie,
If on a beastieI can speel,
Orhurlin a cartie.

Yours,

Robert Burns.
Mauchlin, Monday night, 10 o’clock.
