Sometimes a caravan of travelers will be in the dusty, hot, dry desert, and about to perish for want of water. When this happens they will let one of the camels go. The instincts in this animal will lead him to refreshing waters. When the animal moves nearly out of sight one of the men will mount his camel and follow. When he is about to be out of sight another will do the same. When the camel discovers the water the man following on the camel will turn and wave to the second; the second to the third, and so on, until everyone has gathered at the fresh water. That’s looking out for each other!
