“This afternoon I had put myself down on this sweet spot, very tired of painting [with a view of the old castle of Vorden] .. .. I was completely immersed in thinking of You.. .I would rather like to.. ..thank you, dear and beloved Lady, for the right judgments and remarks which You gave me in this [your?] sweet letter. I solemnly promise you that I will use them for my benefit, and will spent all my powers as an artist, to make your attentions more worthy to me. (translation from Dutch, Fons Heijnsbroek).”
