respects the business was arranged so that I wouldn’t need to have any doubts, and
that would be most likely if the money were here. I do not doubt that you under-

As concerns the vacation, Tete must go for a spa treatment. I was informed not
long ago at a doctor’s examination that his glands are not right and I mustn’t let it
wait. Without me, though, regular treatment could hardly be possible. Perhaps we
can divide the time between us: the first 3 weeks, I take care of him and the last two
weeks he can rest with you.—The vacation lasts approximately from mid-July to
20 Aug.
With kind regards,
Mileva.
