Made by RKO Pathe as part of the WWII industrial incentive effort, “Conquer by the Clock” presents a hectic montage of images of productivity, set to the click of time clocks, the hum of industrial machinery, and the clattering of guns. In wartime America, three 8-hour shifts and 24 hours of work were necessary in munitions plants, shipyards, and other vital factories. In 1943, the film was nominated for an Academy Award.

The film shows the activities in a munitions plant at the 3:30 mark, with rifle cartridges being manufactured. A lazy employee goes off to have a smoke, and as a result a bad batch of bullets is missed. In the end this proves to be a fatal mistake for a soldier in the field, whose rifle misfires in combat and he is killed. It also shows the owner of a wartime plant who goes to watch a baseball game instead of overseeing the loading of a vital survival kit aboard a lifeboat, resulting in the inadvertent death of two men.

Overall, the film encourages American workers to make the best possible use of their time in a war where industrial production and combat are synchronized on an international level. Encourages American wartime workers to “keep their sleeves rolled up.” Describes the volume of industrial and agricultural production that can be accomplished in a single day: enough rifles for a battalion, 1000 acres of corn converted to 30,000 bushels of food.” The film calls tired workers, in effect, “saboteurs”. Narration admonishes workers for the death of soldiers through inadequate equipment or supplies. Utterly melodramatic. Urges workers to move production forward relentlessly. Says that “the clock” is what will win the war.

The film was directed by Director Slavko Vorkapich (1895-1976), the acknowledged master of “montage sequences” — image combination and superimposition techniques that infused often quite ordinary movies with moments of abstraction. With Robert Florey and Gregg Toland, he made the early American experimental film The Life and Death of a Hollywood Extra (1928); later, he made his famous contribution to Ben Hecht and Charles MacArthur’s Crime Without Passion (1934). Besides Conquer by the Clock, he made six other This Is America short subjects for RKO-Pathe, including Private Smith, U.S.A., Women in Arms, Lieutenant Smith and New Americans.

Hank resists the urge to devour a slice of pizza so that he can walk you through the way we experience our major special senses. It all boils down to one thing: sensory cells translating chemical, electromagnetic, and mechanical stimuli into action potentials that our nervous system can make sense of. Today we’re focusing on smell (olfaction) and taste (gustation), which are chemical senses that call on chemoreceptors. As usual, we’ll begin with a quick look at how these things can go wrong.
