Identify the two words that eye rhyme in this excerpt from "The Brigs of Ayr" by Robert Burns. The simple Bard, rough at the rustic plough,
Learning his tuneful trade from ev'ry bough;
The chanting linnet, or the mellow thrush,
Hailing the setting sun, sweet, in the green thorn bush;
The soaring lark, the perching red-breast shrill,
Or deep-ton'd plovers grey, wild-whistling o'er the hill
Shall he-nurst in the peasant's lowly shed,
To hardy independence bravely bred,
By early poverty to hardship steel'd.
