Sisley, I hear, is seriously ill. He is a great and beautiful artist, in my opinion he is a master equal to the greatest. I have seen works of his of… - Camille Pissarro

Look for the kind of nature that suits your temperament. The motif should be observed more for shape and color than for drawing. There is no need to tighten the form which can be obtained without that. Precise drawing is dry and hampers the impression of the whole, it destroys all sensations. Do not define too closely the outlines of things; it is the brushstroke of the right value and color which should produce the drawing. In a mass, the greatest difficulty is not to give the contour in detail, but to paint what is within. Paint the essential character of things, try to convey it by any means whatsoever, without bothering about technique.—When painting, make a choice of subject, see what is lying at the right and what at the left, and work on everything simultaneously. Don't work bit by bit but paint everything at once by placing tones everywhere, with brushstrokes of the right color and value, while noticing what is alongside. Use small brushstrokes and try to put down your perceptions immediately. The eye should not be fixed on one point, but should take in everything, while observing the reflections which the colors produce on their surroundings. Work at the same time upon the sky, water, branches, ground, keeping everything going on an equal basis and unceasingly rework until you have got it. Cover the canvas at the first go, then work at it until you can see nothing more to add. Observe the aerial perspective as well, from the foreground to the horizon, the reflection of the sky, of foilage. Don't be afraid of putting on color, refine the work little by little.—Don't proceed according to rules and principles, but paint what you observe and feel. Paint generously and unhesitatingly, for it is best not to lose the first impression you feel. Don't be timid in front of nature: one must be bold, at the risk of being deceived and making mistakes. One must have only one master—nature; she is the one always to be consulted.

The weather today is frightful, rain and wind. You must be having the same at Epping; it's a pity. It had been so fine for the last few days and I had begun to grind away from nature. This is infuriating, for it's the loveliest time of the year, September and October. I can't stand the summer any more, with its heavy, monotonous green, its dry distances where everything can be seen, the torment of the great heat.. .Artistic sensations revive in September and October, but then it rains and blows!

I think continually of some way of painting without the dot. I hope to achieve this but I have not been able to solve the problem of dividing the pure tone without harshness.. .How can one combine the purity and simplicity of the dot with the fullness, suppleness, liberty, spontaneity and freshness of sensation postulated by our impressionist art? This is the question which preoccupies me, for the dot is meager, lacking in body, diaphanous, more monotonous than simple, even in the Seurat's, particularly in the Seurat's [paintings].. .I'm constantly pondering this question, I shall go to the Louvre to look at certain painters who are interesting from this point of view. Isn't it senseless that there are no Turners [here]..
