Oh! lonely, gentle, unobtrusive mule!
Thou standest idly 'gainst the azure sky,
And sweetly, sadly singeth like a hired man.
Who taught thee thus to warble
In the noontide heat and wrestle with
Thy deep, corroding grief and joyless woe?
Who taught thy simple heart
Its pent-up, wildly-warring waste
Of wanton woe to carol forth upon
The silent air?
