A USDA production conveying the department's policy recommendations for the development of unusable wetlands into productive agricultural land. Narration explains that, for much of the year, land with "too much water with nowhere to go" is rendered unsuitable for farming. Engineering the draining of 31 million acres for the creation of productive agricultural land represents "one of the last great frontiers of America." Various drainage techniques are explained in detail: ditches, tile systems, and the creation of mole channels. "Shows where our 120 million acres of wet land are located. Points out that 78 million of these acres will serve us best if left in their natural state for the production of timber and the preservation of wildlife. Thirty-one million acres are shown to be suited to farming if properly drained. A section of the film illustrates briefly the principal types of water control and methods of land drainage. Through the use of these methods, farmers, working together, can improve drainage on land now being farmed, and bring into production land that is now too wet for any production at all.
