"When the mistletoe bats on Errol's aik,
And that aik stands best,
The Hays shall flourish, and their good
grey hawk
Shall not flinch before the blast.
But when the root of the aik decays
And the mistletoe dwines on its withered breast
The grass shall grow on Errol's hearthstone,
And the corbie roup (croak) in the falcon's nest."
Thomas the Rhymer
