Agriculture. Guayule cultivation. Seedling topper at work on guayule nursery beds. This machine mows the seedlings off to a uniform height for ease in digging and packing. The tops are collected in a bin on the machine and disposed of outside of the nursery. The tops are worthless for rubber production. Guayule plantings will produce an estimated 600 tons of rubber in early 1943, provide a crop in 1944 which should yield 33,000 tons and a harvest in 1945 to yield 47,000 tons. An annual production of 70,000 tons to 80,000 tons will materialize if full capacity of nurseries now being built is utilized. Addition: This program is part of the Department of Agriculture's Emergency Rubber Project, administered by the Forest Service under congressional authorization "to make available a source of crude rubber for emergency and defense uses"

Negro Marines prepare for action. Breaking a tradition of 167 years, the U.S. Marine Corps started enlisting Negroes on June 1, 1942. The first class of 1,200 Negro volunteers began their training three months later as members of the 51st Composite Defense Battalion at Montford Point, a section of the 200-square mile Marine Base, Camp Lejeune, at New River, North Carolina. Among the outstanding Negroes in the original group of Negro Marines is Private First Class Walker Manley, formerly organist of the Christian Church in Raleigh, North Carolina, and a demonstrator for the Hammond Organ Company, who is now post organist at Camp Lejeune. In addition to being organist for the Montford Point chapel, he is also organist for several of the chapels where white enlistees worship

The digger is a four foot long blade which is drawn through the ground under the plants, cutting the roots loose and uprooting the plants. Guayule plantings will produce an estimated 600 tons of rubber in early 1943, provide a crop in 1944 which should yield 33,000 tons and a harvest in 1945 to yield 47,000 tons. An annual production of 70,000 tons to 80,000 tons will materialize if full capacity of nurseries now being built is utilized. Addition: This program is part of the Department of Agriculture's Emergency Rubber Project, administered by the Forest Service under congressional authorization "to make available a source of crude rubber for emergency and defense uses"
