1793, John Clendinin published a small book of about 100 pages
consisting of two sets of calculated tables for use by surveyors.
Of special interest in this book is a section consisting of 4 pages of
names of "subscribers". Apparently these
"subscribers" were willing to commit in advance to buy a
copy(s) of the book. The list is interesting in part because of
the titles given to these people. The real question is, why did
some of them want the book. The book did have a second printing
which left out the list of "subscribers".
The book itself
does not have any reading material and consists solely of two very
tedious sets of tables. Examples are shown below.
