The following letter was found in a baking-power can wired to the handle of an old pump that offered the only hope of drinking water on a very long and seldom-used trail across Nevada's Amargosa Desert:
This pump is all right as of June 1932. I put a new sucker washer into it and it ought to last five years. But the washer dries out and the pump has got to be primed. Under the white rock I buried a bottle of water, out of the sun and cork end up.
There's enough water in it to prime the pump, but not if you drink some first. Pour about one-fourth and let her soak to wet the leather. Then pour in the rest medium fast and pump like crazy. You'll git water. The well has never run dry. Have faith. When you git watered up, fill the bottle and put it back like you found it for the next feller.

P.S. Don't go drinking the water first. Prime the pump with it and you'll git all you can hold.
