Here I have been able to make some good spring studies in oils, and managed to finish my 'Cow-girl' and my 'seared Woman', and my 'London Park', Primrose Hill. I think these pictures have improved a great deal from the point of view of unity. How different from the studies! I am more than ever in favour of taking one's impression from memory; it is less the actual thing - vulgarity disappears, leaving only an aura of truth glimpsed, sensed. To think that this is not understood, so that my anxiety for the future continues as before, despite the success of the exhibition. – I have no news from Paris about my collectors.
