What I consider to do with the new course [at The Academy of Art in The Hague] is: in the morning doing large plaster and in the afternoon painting or drawing after Nature, what I am doing already for some time, and [drawing] horses in the Municipal Horse Riding School. The Director is Sir Krüger, a very charming German who has seen of course many horses and so he knows how to show me the mistakes I make, which are not few.
