This is the Rite in the Rain No. 310F, a 4.75 by 7.5 inch hard-cover field book with 160 pages of all-weather paper in the Level pattern. The Fabrikoid cover, the sewn binding, and even the glue are weatherproof, and the pages are sequentially numbered.
It records level runs, surveys, and site inspections where the record may need to stand up later — sewn-bound, numbered pages are the requirement for legally admissible field books. Write with a #2 pencil or an all-weather pen in any conditions.
Rite in the Rain has made all-weather writing paper in Tacoma, Washington since 1916, when it was developed for logging crews in the Pacific Northwest.
