Steven and Arthur,

This is great! Thank you for considering it Steven. I realize it may be a
while before you find time to do the work but, like Arthur, I'd like to do
anything I can to help.

One thing I can do, if you'll send me your address, is donate a copy of my
tables. You may not want a copy for your own use, but I'd like you to be able to
look it over.

While the prop log tables are based on the number of seconds in three hours,
table 7 is based on the number of tenths of a minute of arc in four degrees,
and table 8 on the number of seconds in an hour. Enter table 8 with 50 seconds
and it gives you the log of 3600/50.

Table 7 deals with change in distance, but goes to four degrees so it can
also proportion altitudes taken before and after the distances.

Neither of these tables can deal with a three-hour interval, at least not in
the usual straightforward way.

Some time ago I made a prop log table so as not to wear out the old
navigation manuals while working Lewis & Clark's lunars. But if I try to send it the
formatting will probably fall apart. I'm not at all computer savvy. It might be
best for one of you to create the table. But if you're willing to coach me,
this one might come through OK after a few tries.

Bruce
