Scope & Content Reference 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.

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.
