Builders arrive at a factory site and clear it prior to digging drains and laying bricks. One of the bricklayers talks about his job, saying that he doesn't feel as though he's taking part in the war.

But new factories are vitally important to the war effort, especially munitions factories. Every minute saved in the building of a new factory can mean the production of fifty new cartridge cases. Planes, tanks and guns are assembled, and a bomber takes off from a runway.

The workmen wonder why it takes a war to get things done. One of them reads out a clipping of a speech by General Wavell saying that the same amount of energy must be exerted in peacetime.
