Let me sleep. The day is past,
And the folded shadows keep
Weary mortals safe and fast.
Let me sleep.

I am all too tired to weep
For the sunlight of the Past
Sunk within the drowning deep.

Treasured vanities I cast
In an unregarded heap.
Time has given rest at last.
Let me sleep.

Robert Fuller Murray
