"A sprightly color cartoon showing how, down through history, humans have worked to find the easy way. First we harnessed the power of animals, then fire, then combustible fuels. Today we are still looking for new servants, this time from the atom. The film was produced in 1959."

"A sprightly cartoon, showing, from the dawn of history, the way man has used his brain to win over nature and other animals."
