"I recently saw the exhibition of French art (on the Boschkant) [The Hague] from the collections of Mesdag, Post &c. .. ..I especially liked the large sketch by T. Rousseau from the Mesdag collection, a drove of cattle in the Alps. And a landscape by Gustave Courbet 'Hilly landscape', 1858/59], yellow hilly, sandy ground, with fresh young grass growing here and there, with black brushwood fences against which a few white birch trunks stand out, grey buildings in the distance with red and blue slate roofs. And a narrow, small, light delicate grey band of sky above. The horizon very high, however, so that the ground is the main thing, and the delicate little band of sky really serves more as contrast to bring out the rough texture of the masses of dark earth. I think this is the most beautiful work by Courbet that I've seen so far."
