. . .do we know what it looks like?
    A Puzzle for you. . .                      

Clouded with snow
The cold winds blow,
And shrill on leafless bough
The robin with its burning breast
Alone sings now.
 The rayless sun,
Day's journey done,
Sheds its last ebbing light
On fields in leagues of beauty spread
Unearthly white.
 Thick draws the dark,
And spark by spark,
The frost-fires kindle, and soon
Over that sea of frozen foam
Floats the white moon.
