Water Bags Water Bags

These canvas drinking water bags were commonly used on North American farms from the early days of the settlers. The ones shown here were made by Eagle Brand, patented in 1945.

The bags required preliminary seasoning they were repeatedly filled with water, which was left to

seep through the material. Eventually, less and less water would escape as the bag's fibres expanded, making it virtually watertight.

Evaporation from the exterior of the bag absorbed heat as some of the water was converted to vapour.

Water Bags The evaporation kept the drinking water cooler than the surrounding air. To illustrate, think of when the human body becomes overheated and is cooled by the evaporation of sweat.

The lever on the side of the drinking cap was pressed downwards to secure the cap tightly to
the bag.

Even today, canvas drinking water bags are used in various parts of the world because of their low-cost effectiveness.
