124 THE BALLADS 4 And then bespake the strings all three, O yonder is my sister that drowned mee.' (10 A, 16.) Like some of the talking birds, this implies a belief in reincarnation; or, as Wimberly calls it, the "object-soul". The clearest example of reincarnation, however, is that of lovers' souls going into plants which grow from their graves, as in Earl Brand: Lord William was buried in St. Mary's kirk, Lady Margaret in Mary's quire, Out o the lady's grave grew a bonny red rose, And out of the knight's a briar. This motif is repeated in half a dozen other ballads, as a fitting end to a tragic love story. It is still a favourite with modern American ballad singers: * Sweet William was buried in the old church tomb Barbara Ellen was buried in the yard. Out of sweet William's grave grew a green, red rose Out of Barbara Ellen's a briar. 'They grew and they grew to the tall church door; They could not grow any higher. They linked and tied in a true lover's knot And the rose grew round the briar.'8 A number of ballad motifs centre upon the magical virtues of blood, perhaps because it, too, was once regarded as a vehicle of the soul. Johnie Cock and his dogs drink the blood of the deer, and that is probably a relic of contagious magic: they do so that the swiftness of the deer may be transferred to them.
