O' Night's Black Arch.

"By this time he was cross the ford,
Whare, in the snaw, the chapman smoor'd;
And past the birks and meikle stane,
Whare drunken Chairlie brak 's neck-bane;
And thro' the whins, and by the cairn,
Whare hunters fand the murder'd bairn;
And near the thorn, aboon the well,
Whare Mungo's mither hang'd hersel'.--
Before him Doon pours all his floods;
The doubling storm roars thro' the woods..."

- from Tam O'Shanter, by Robert Burns.
