Scope & Content Reference book: Solar Ephemeris for 1940 and other Tables and Data useful to the Surveyor. Published by Keuffel & Esser Co., N.Y., copyright 1940. Softcover booklet, 3-3/8" x 6" high, 94 pp. plus stiff orange wrappers, diagrams, illustrations. PDF on file.

A typical example of this annual publication issued by K&E for circa 80 years. A field reference work, it does include instructional information for use of selected types of instruments. Alidades and plane table (plane-table) surveying are covered in this edition. Promotional advertisements for related K & E products are found near the end including slide rules, drawing instruments, tapes and band chains, papers and field books.

While the cover and title page state New York, K&E had their offices and factory in Hoboken at this time.

THIS new edition of the Solar Ephemeris remains essentially the same as the previous issue; the method of determining the meridian by observing Polaris at any hour angle being fully explained.

A complete Index will be found on page 94.

We will be glad to supply additional copies of this little hand book upon application.
