None could give a more perfect rendition of Scotch music and poetry than they.
When Miss Douglas sang "The Winter is Past," another of Burn's melodies, Mary Douglas fancied she saw the beautifully chiselled lips of Lady Rosamond tremulous with emotion.

The first verse ran thus: "The Winter is past, and the Summer's come at last, And the little birds sing on every tree; Now everything is glad, while I am very sad, Since my true love is parted from me." The finely cultivated voice of the singer entered fully into the spirit of the song, giving both expression and effect as she sang the last verse: "All you that are in love and cannot it remove, I pity the pains you endure: For experience makes me know that your hearts are full of woe, A woe that no mortal can cure." "One would judge that my sister had some experience, if we take the face as an index of the mind," said Captain Douglas, in playful badinage directed towards his favorite sister, who in reality did have an experience, but not of her own.
She felt the blow thus unconsciously dealt at Lady Rosamond.

Luckily for the latter, the coincidence thus passed over without any betrayal of feelings.

In Mary Douglas was a firm and watchful ally.

In her were reflected the feelings which passed unobserved in Lady Rosamond, or attributed to absence from home, separation from familiar faces, or clinging memories of the past.
