"US government propaganda film made during WWII touting the virtues of hemp. The film was aimed at farmers at a time when the miltary was facing a shortage of hemp, it shows how hemp is grown and processed into rope and other products."
Public domain film slightly cropped to remove uneven edges, with the aspect ratio corrected, and mild video noise reduction applied.
The soundtrack was also processed with volume normalization, noise reduction, clipping reduction, and equalization.

Hemp (from Old English hænep) is a term reserved mainly for low tetrahydrocannabinol (THC) strains of the plant Cannabis sativa. Of the approximately 2000 cannabis plants varieties known, about 90% contain only low-grade THC and are most useful for their fiber, seeds and medicinal or psychoactive oils. Scholars believe that hemp is humankind's oldest cloth and hemp-limestone composites have been found in ancient Roman architecture.
In modern times hemp is used for industrial purposes including paper, textiles, clothing, biodegradable plastics, construction (as with Hemcrete and insulation), body products, health food and bio-fuel. Hemp is thus legally grown in many countries across the world including Spain, China, Japan, Korea, England, France, Africa, North Africa, Egypt and Ireland. Although hemp is commonly associated with marijuana (hemp's THC rich cousin), since 2007 the commercial success of hemp food products has grown considerably.
Hemp is one of the faster growing biomasses known, producing up to 25 tonnes of dry matter per hectare per year. A typical average yield in large scale modern agriculture is about 2.5--3.5 t/ac (air dry stem yields of dry, retted stalks per acre at 12% moisture). Approximately one tonne of bast fiber and 2--3 tonnes of core material can be decorticated from 3--4 tonnes of good quality, dry retted straw.
Hemp is very environmentally friendly as it requires few pesticides and no herbicides. It has been called a carbon-negative raw material...
Hemp is one of the earliest domesticated plants known.
Cannabis sativa L. subsp. sativa var. sativa is the variety grown for industrial use, while C. sativa subsp. indica generally has poor fiber quality and is primarily used for recreational and medicinal purposes. The major difference between the two types of plants is the appearance and the amount of Δ9-tetrahydrocannabinol (THC) secreted in a resinous mixture by epidermal hairs called glandular trichomes, although they can also be distinguished genetically. Oilseed and fiber varieties of Cannabis approved for industrial hemp production produce only minute amounts of this psychoactive drug, not enough for any physical or psychological effects. Typically, hemp contains below 0.3% THC, while cultivars of Cannabis grown for recreational use can contain anywhere from 2% to over 20%.
The world leading producer of hemp is China with smaller production in Europe, Chile and North Korea... more hemp is exported to the United States than to any other country...
Hemp is used for a wide variety of purposes including the manufacture of cordage of varying tensile strength, durable clothing and nutritional products. The bast fibers can be used in 100% hemp products, but are commonly blended with other organic fibers such as flax, cotton or silk, for apparel and furnishings, most commonly at a 55%/45% hemp/cotton blend. The inner two fibers of hemp are more woody and are more often used in non-woven items and other industrial applications, such as mulch, animal bedding and litter. The oil from the fruits ("seeds") oxidizes... to become solid on exposure to air, similar to linseed oil, and is sometimes used in the manufacture of oil-based paints, in creams as a moisturizing agent, for cooking, and in plastics. Hemp seeds have been used in bird seed mix as well. Hempseed is also used as a fishing bait...
