Clerk and laic, grave and gay!

Yet do ye, before the rest,

Gentle maidens, mark me tell!

Store my lesson in your breast,

Trust me it shall profit well:

Hear, and heed me, and be bless’d!’

So sang the bird of old; but when he spied

The carle draw near, with alter’d tone he cried—

‘Back, river, to thy source! and thee, tall tower,

Thee, castle strong, may gaping earth devour!
