Manual labor camps (Civilian Conservation Corps) as part of Roosevelt’s New Deal. At the height of the program there were 300,000 young men age 17 -28 helping to plant billions of trees and creating over 800 national parks. They also worked on bridges and fire towers, roads and footpaths, flood control and erosion control, fish stocking, mosquito control, removal of predatory animals, rip-rapping, surveying and irrigation.
Men were provided with shelter, clothing, food and $30 a month ($25 of which was to be sent home to their families).
The camps included a mess hall, tents for the men and for the staff, lavatories, garages, blacksmith shops, administrative buildings, entertainment halls and education halls.
In the nine years the program was in place over 3 million men were enrolled.
