An Educational films corporation of America production available only to schools. "Here we have a description of some of the ways in which waves affect mankind. Gravel is taken from a river bed for concrete; a river is dammed to aid navigation and supply power and irrigation. The Columbia River, which makes Portland a tideless seaport 110 miles from the sea, is seen as an important travel way for salmon. Striking views of the salmon running at spawning time, with leaping waterfalls, are shown."
