There is probably some very good information contained in this book and I wish I could read it. I managed about 3 pages before I gave up. The regretable use of the old english typeface and characters was a very tragic mistake by the publisher. The price of the book made it uneconomic to return, so sadly it will wind up one of the very very few books that I consign to the garbage can. What a waste of paper and ink. If only they had printed it so the average person today that is intested in surveying could read it, it would have been both a delightful and useful book.
