A traveler going through the Arizona desert was overcome with thirst. He had almost given up all hope when he came upon a water pump that had a note on the handle.

The note read: “This pump is all right as of June 1962. I put a new washer in it, but the washer dries out and the pump needs to be primed. Under the white rock I have buried a bottle of water. There is enough water in the bottle to prime the pump, but not if you drink the water first. Pour about one-fourth of the water on the leather washer first and let it soak in. Then, pour the rest of the water over the washer and pump like crazy. You’ll get plenty of water. Remember—don’t go drinking from the bottle first. When you are done, fill the bottle up and put it back under the white rock where you found it for the next feller.
