C. M. It isn't as noisy as I thought it would be, though.
A. M. Oh, I don't know. It's quite noisy enough.
B. M. Yes, it's very difficult to concentrate one's mind. We've got a waterfall in Brazil which has the same effect. You can't do any work near it. People go there for a rest-cure.
C. M. There are a good many waterfalls in Chili, too, and they make more noise than this one.
(A pause.)
A. M. How long do you think we shall be here?
B. M. A week, or a month, or a year—I don't know.
C. M. It's a dull place, isn't it?
A. M. Yes, it is, dull as ditchwater.
B. M. Dull as a ditchwaterfall. Ha, ha.
