Mild shelf and edge wear. Binding tight. Green and cream marbled endpapers, blue-stained page edges. Pages clean and unmarked. Laid in is a single typed sheet, printed both sides, headed National Advisory Committee for Aeronautics, General Information for Employees (A Digest of the Administrative Regulations), approved April 1, 1944, numbered 300 at head and typed with the name of the employee, Tilford R. Crandol. Sheet toned and folded horizontally, with mild edge wear. Volume 180 in the bound series issued by International Textbook Company, the publishing arm of the International Correspondence Schools of Scranton, Pennsylvania. ICS grew out of a mine-safety question-and-answer column run by Thomas J. Foster in the Colliery Engineer and Metal Miner and enrolled its first class of 500 miners in 1891; cumulative enrollment reached four million by 1930, making it the most successful correspondence school in American history. The bound volumes gathered the loose serial-numbered Instruction Papers into permanent form, this one comprising Planers (Serial 2212, Edition 1) and Planer Practice. A working manual for the metal planer, the machine tool that produced the flat surfaces of the machine age before the milling machine displaced it: planer beds, tables, cross-rails and heads, belt and geared drives, variable-speed devices, feed mechanisms and lubrication systems, then the tooling and setups of the trade, roughing and finishing tools, chucks, parallels and V blocks, bolts, clamps and toe dogs, cutting speeds, T slots and undercuts, bevels and curved surfaces, and the planing of engine and lathe beds. The laid-in sheet carries a wartime association. NACA, the federal aeronautical research agency founded in 1915 and absorbed into NASA in 1958, ran the laboratories behind much of American aerodynamic research; this digest covers employees at both Langley Field and Moffett Field, with a separate provision for Ames. Its Security section forbids removing official correspondence, data, or photographs from the Laboratory, bars employees from photographing buildings or equipment, requires confidential material locked away outside working hours, and excludes visitors without the approval of a Washington officer of NACA. Other sections set the six-day working week, wartime restriction of annual leave to twenty days, savings-bond allotments, and a prohibition on political activity. Crandol appears in no published NACA research listing, and that a copy of these regulations was kept inside a machine-shop textbook suggests an owner working in the shops rather than in research. A later printing, the sections carrying copyrights of 1934 and 1936 over the 1927 originals.
