The Peek Frean biscuit factory, Keeton's Road, Bermondsey, South London.

The boiler room generates the steam that runs the overall biscuit-making operation. Milk and flour is delivered and unloaded. The various ingredients are collected, weighed and mixed, and the resulting dough is rolled out onto trays. These are placed in the cutting machine to form the biscuit shapes, and then transferred to the ovens. After baking, women pack the biscuits into tins.

The factory workers undergo a fire drill (with appliances) in the yard and have a lunch break. Empty biscuit tins are washed, and full tins are weighed, labelled and soldered for export. The tins are packed into crates and boxes and loaded onto a conveyor belt.

Horse-drawn carts and vans are assembled and loaded. They transport the biscuits out of the factory for distribution to the outside world.
