Full Moon

The moon is but a silver watch
To tell the time of night;
If you should wake, and wish to know
The hour, don't strike a light.

Just draw the blind, and closely scan
Her dial in the blue:
If it is round and bright, there is
A deal more sleep for you.

She runs without an error,
Not too slow nor too quick,
And better than alarum clocks--
She doesn't have to tick!
