Scope and ContentReference book: Solar Ephemeris for 1945 and other Tables and Data useful to the Surveyor. Published by Keuffel & Esser Co., N.Y., copyright 1944. Softcover booklet, 3-3/8" x 5-7/8" high, 96 pp. plus stiff orange wrappers, diagrams, illustrations. 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 which is listed on the title page. ---- page 3: KEUFFEL & ESSER CO., New York 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. ---- Text of index as found on page 94.
