A friend sent me lyrics to the lullaby that is called, I think, Mist On The Mountain (NOT Mist Covered Mountains). I don't know if this is trad or has a known author. Here is what he wrote, without the title:
Hush, hush, time to be sleeping,
Hush, hush, dreams are a creeping,
Dreams of peace and of freedom,
So smile in your sleep Bonnie Baby.
Once our valleys were ringing,
With sounds of children singing,
But now sheep bleat in the evening,
And sheelings lie empty and broken.
We stood with heads bowed in prayer,
While factors laid our cottages bare,
The flames licked the clear mountain air,
And many were dead by the morning.
Where was our fierce highland mettle,
Our men once so fearless in battle,
Now stand cold, huddled like cattle,
And wait to be shipped in the morning.
No use in crying or pleading,
Gone, gone, all hopes of staying,
So hush, hush, the anchor's aweighing,
Don't cry in your sleep Bonnie Baby.
Note:This song, properly known as "Smile in Your Sleep," was written by Jim McLean. It appears unattributed in the Digital Tradition, under the title Don't Cry In Your Sleep (click). I submitted a corrected attribution to the Digital Tradition, and the correction has been made.
