Almost any environment has water present to some degree. Figure 6-1 lists possible sources of water in various environments. It also provides information on how to make the water potable. Shape the plastic or cloth into a bowl by pleating it. If you do not have a reliable source to replenish your water supply, stay alert for ways in which your environment can help you.
Heavy dew can provide water.
Tie rags or tufts of fine grass around your ankles and walk through dew-covered grass before sunrise. As the rags or grass tufts absorb the dew, wring the water into a container. Repeat the process until you have a supply of water or until the dew is gone. Australian natives sometimes mop up as much as a liter an hour this way. Bees or ants going into a hole in a tree may point to a water-filled hole.
