"Ca' the yowes to the knowes" ("Drive the ewes to the hills") is a Scottish folk song collected by Robert Burns from 1794. Although sometimes attributed to Burns himself, the seven-stanza original poem is thought to be the work of Ayrshire poet Isabel Pagan, a contemporary of Burns. The poem was partially revised by Burns, and he added an eighth stanza. Burns later re-wrote the poem on a solitary stroll in the country, and this second version consists of six stanzas.It is possible that Burns was not aware that Pagan was the original author, only noting that "this song is in the true Scottish taste, yet I do not know that either air or words were ever in print before."

 

The original text is a pastoral love poem spoken from the point of view of a shepherdess herding her ewes ("yowes"), who has a romantic meeting with a shepherd lad. Burns's revised version is less explicit about the identity of the narrator, but follows a similar theme of love amid the beauty of nature. Both versions include the refrain, "Ca' the yowes to the knowes".
