- Tinkham, Capt. R. R. Tinkham. TECHNICAL PHASES OF LIGHTHOUSE SERVICE. The Military Engineer Magazine. May-June. 1925. pp. 240-248. Ralph Russell Tinkham enjoyed the challenge of building lighthouses in remote, inaccessible areas. As a junior engineer of the U. S. lighthouse Establishment, he worked on the construction of Split Rock Light Station in 1909, which would consume almost 1 ½ years of his life and catapult his career in the U.S. Lighthouse Service. By the time of his retirement in 1946, Tinkham had become the Chief Engineer of the U.S. Lighthouse Service. This detailed and informative illustrated article by Tinkham includes a detailed overview of the scope and operations of the Lighthouse Service, types of fixed aids to navigation, shore stations, site difficulties, lanterns, lenses, light sources, radio and fog signals, and much more. Other articles include “The Panama Canal After Ten Years” by Governor Meriwether L. Walker; “Broader Aspects of Cadastral Engineering” by Frank M. Johnson; “Signal Corps Lays The Alaskan Cable” by Lt. Col. C. A. Seoane; “Railroads In Theater of Operations” by Brig Gen Edgar Jadwin; and more. Included is a second issue of The Military Engineer Magazine, September-October, 1925. Interesting articles include “Topographic and Geological Maps” by George Smith; “New Ways for Old In New England” by Capt. Billings Wilson; “Streets and Highways of Honolulu” by Capt. V. B. Libbey; “Emergency Dams At Seattle Canal Locks” by A. W. Sargent; and more. Issues nicely intact, some staining and wear to wraps, contents clean and tight. (VG). $68.
