A faint wind, blowing from World's End,
Made strange the city street.
A strange sound mingled in the fall
Of the familiar feet.
Something unseen whirled with the leaves
To tap on door and sill.
Something unknown went whispering by
Even when the wind was still.
And men looked up with startled eyes
And hurried on their way,
As if they had been called, and told
How brief their day.

Sir Charles George Douglas Roberts
