None can tell how sweet,
How virtuous, the morning air;
Every accent vibrates well;
Not alone the wood-bird's call,
Or shouting boys that chase their ball,
Pass the height of minstrel skill,
But the ploughman's thoughtless cry,
Lowing oxen, sheep that bleat,
And the joiner's hammer-beat,
Softened are above their will,
Take tones from groves they           through
Or flutes which passing angels blew.
