Ruskin tells Heaton that White has agreed to exchange Heaton's vignette, with an additional 10 guineas, for Turner's vignette of Rhymer's Glen, or Heaton's vignette, plus an additional 40 guineas, for Turner's Dryburgh Abbey vignette. Ruskin advises to only give an additional 20 guineas if she takes the Dryburgh. Ruskin states that the Rhymer's Glen is exquisite and likely to always have high value but that he is less sure about the Dryburgh as he "suspect[s] the colours a little". Ruskin ends by saying that if she doesn't like the exchange she should wait for a better one but to let White know whether she will accept the offer by the next Monday.
