Paul, thanks. he relies only on astronomical means, and never mentions harbor time signals. Either he considers this too trivial to mention, or, perhaps they were not made in the US at that time. It is interesting when they started to make them: a) in Greenwich b) in most major harbors. In Greenwich, you can still see a big ball dropped from a spire on the observatory at noon, and perhaps many other harbors still have this. Alex.
