"As paint I use lightfast printing ink, usually pure, but also mixed. Mixing is not difficult at all, it but can happen in very different ways. Secret means are not applied, but I can not work on them, except in solitude . No one works in this way. I believe that no one else can obtain the same color effects, except after a lot of practice and experience. Sometimes one print goes up to 50 times under the printing-press. Never more than one piece per day."

“I have applied for a pass and I am going to travel through Western Europe for 5 days. start in Cologne and will probably end in Paris. Who cares.

He was so enthusiastic that I suspect to be able to note him as my traveling companion.”

“Last Sunday we made a bicycle tour of 80 km. Through the North along the edge of the province .. ..On such a day I get again a lot of impressions which will reappear in altered forms in due time. Beautiful landscapes, nice small roads, beautiful farms, meadows with horses and cattle, birds, water and a lot of sunshine. Mills and towers and trees are breaking the lines of the flat land..”
