"I agree completely with your remark that in the struggle against nature lies already a part of art, and really pleasant is for me already the feeling of returning as a victor from small skirmishes, although in the great battle one always feels still defeated. As you advised me, I have made sketches of skies, indicating the effect in them, and making a note for the important colors; I also did better in making a small sky; at least people think so. (translation from the Dutch original: Fons Heijnsbroek)"
