The moon appeared for some time [in the Savoy, Switzerland] and the rocks seemed to be much bigger than they were. The mountains were silvery illumin… - Gerard Bilders

Yesterday I received a letter from my father [ Dutch landscape-painter J. W. Bilders.] He told me to come at once, to paint the goats in a rather large forest landscape-painting he just finished, which has to be sent away at once [to Saint Petersburg, Russia]. I earn back my travelling [from Leiden to Amsterdam, probably by travel coach] but will loose one day studying in open air. When my goats will succeed, and they are not too stubborn, I'll be back here [in Leiden] tomorrow at one o'clock in the afternoon.

version in original Dutch / citaat van Bilders' brief, in het Nederlands: Ik zoek naar een toon, die wij gekleurd-grijs noemen; dat is alle kleuren, hoé sterk ook, zoodanig tot één geheel gebragt, dat ze de indruk geven van een geurig, warm grijs.

Friday 11. I have found there [at the [[w:Mauritshuis|museum 'Mauritshuis'] ]] already refuge - in front of Potter's big Bull. That is I started to copy the sheep with the lamb, which will not be a easy task, notwithstanding its great simplicity. The longer I look at that painting, the more beautiful things become visible to me, and when I wasn't convinced for sure that I was sitting in front of my painting easel in The Hague at the Mauritshuis, I would believe that the animals were alive and were - just as in the meadows in Oosterbeek - staring at me with their stupid faces, and asking: - what are you doing there?
