Dear Theo,

. . . . Yesterday I drew some decayed oak roots, so-called bog trunks (that is, oak trees which have perhaps been buried for a century under the bog, from which new peat had been formed; when digging the peat up, these bog trunks come to light).

These roots were lying in a pool, in black mud.

Some black ones were lying in the water, in which they were reflected, some bleached ones were lying on the black earth. A little white path ran past it all, behind that more peat, pitch–black. And a stormy sky over it all. That pool in the mud with those rotten roots was completely melancholy and dramatic, just like Ruysdael, just like Jules Dupré.

This is a scratch of the peat fields.

There are very often curious contrasts of black and white here, for instance, a canal with white sandy banks, across a pitch–black plain. In the above sketch you can see it too, black figures against a white sky, and in the foreground again a variation of black and white in the sand.
