Do you see all those beautiful trees there ? I sketched them all thirty years ago; I have had all their portraits. Look at that beech there, the sun … - Théodore Rousseau

Do not be anxious about [an ordered painting] 'La Ferme' my dear Mr. Hartmann, I am anxious to establish in this picture such a decision deformed, that it may exist, independently of the caprices of the light, and of the influence of the hours of the day. I am regulating it, absolutely as a watchmaker regulates a watch after he has finished it.

If my painting depicts faithfully and without over-refinement the simple and true character of the place you have frequented, if I succeed.. ..in giving its own life to that world of vegetation, then you will hear the trees moaning under the winter wind, the birds that call their young and cry after their dispersion ; you will feel the old chateau tremble; it will tell you that, as the wife you loved, it too will.. ..disappear and be reborn in multiple forms.. One does not copy with mathematical precision what one sees, but one feels and interprets a real world, all of whose fatalities hold you fast bound.

* Charles Jacque to Th. Rousseau: 'I should think you got weary here'.
* Rousseau: 'That depends; when you wish to do so, one can always find beautiful things to study and understand. Look here at this charcoal-burner [in the field] before us, with his big felt hat - who is thinking of his sacks and of his faggots sees how the shadow of those large brims gives a clear yet grave tint to his face'.
* Charles Jacque: 'Draw him, Rousseau, in this pensive attitude, he does not doubt that he is handsome, and if he posed himself he would become repellent. See, here is a sketch-book, go on!'
