What may it be?

MAURTEEN BRUIN.

I do not rightly know;

It has been in the thatch for fifty years.

My father told me my grandfather wrote it,

Killed a red heifer and bound it with the hide.

But draw your chair this way—supper is spread.

And little good he got out of the book,

Because it filled his house with roaming bards,

And roaming ballad-makers and the like,
