'Tis not enough no harshness gives offence,
The sound must seem an Echo to the sense: 365
Soft is the strain when Zephyr gently blows,
And the smooth stream in           numbers flows;
But when loud surges lash the sounding shore,
The hoarse, rough verse should like the torrent roar:
When Ajax strives some rock's vast weight to throw, 370
The line too labours, and the words move slow;
Not so, when swift Camilla scours the plain,
Flies o'er th' unbending corn, and skims along the main.
