Just a word about the [Bertrand] Russell business, as he may wonder at the delay in replying to his letter. There is nothing for us to say except, Very well. It gives us a breathing spell in the hard times, but I suppose we can manage to resume the payments later if they are needed. Next September you will send him his $2,500, as expected; but in 1939 you will not send him anything, unless he again asks for it. You see he is very honest, and even ascetic. He likes to be poor and hard-worked, although his fundamental standards are aristocratic, and sometimes break through.
