If you have these in your pantry-the coconut chocolate chip ones, you better lock it and hide the key...from yourself. It can't be long before they are banned in N.Y. City.

In: My First Summer in the Sierra(about his summer herding sheep and exploring the Yosemite area in 1869), John Muir often writes of how important his bread is. He carries and uses a sourdoughs starter on this trip into the California mountains.

On p.73 he writes of how nice the clouds are then ..."But in the midst of these sky and mountain affairs a change of diet is pulling us down. We have been out of bread a few days, and begin to miss it more than seems reasonable, for we have plenty of meat and sugar and tea. Strange we should feel food-pour in so rich a wilderness. The Indians put us to shame, so do the squirrels,- starchy roots and seeds and bark in abundance, yet the failure of the meal sack disturbs our bodily balance, and threatens or best enjoyments."
