He [the painter J. A. Kruseman in Amsterdam] is very amicable with his students without exposing his mastery to disdain. I sometimes see him painting from time to time. And I almost visit daily his studio. You must know that his students don't work in the same room where the big man is staying... Sometimes one or two days pass that he doesn't see our work, he let follow the students their own way most of the time... Thanks God he tells me I have feeling and talent.
