Bosboom has just as anyone else fussed around things [paintings] from time to time to get his money. Only very few people can escape this... It is almost impossible that an artist who doesn't have the gift to work for the market as well, will always have to make good things. Because, when he has no money he has to earn it. And he will have to strain himself. For something he appreciates the least of all. He can never neglect this... The examples you can see everywhere. If you may write something about him [Bosboom] again, I hope you will take this into account too.
