Salt of the Blood

Salt of the Blood is ocean bathing still,
Each cell of brain and heart burning uphill.
—Thomas Hornsby Ferril

Although he certainly could appreciate the unique flavor of sea salt compared with rock salt, Clark was indifferent toward salt as a flavoring. "I care but little," he wrote, "whether I have any with my meat or not, provided the meat fat, having from habit become entirely cearless about my diat, and I have learned to think that if the Cord be Sufficiently Strong which binds the Soul and boddy together, it does not So much matter about the materials which Compose it."

On the contrary, it does.

The formula is simple. One molecule of sodium, a reactive metal, plus one molecule of chlorine, a poisonous gas, equals a harmless mineral that once was Salt Camp in 1899deemed "the fifth element," along with earth, air, fire, and water. Indeed, all living creatures are still awash in the salty sea that gave birth to the first living cell. It fills the spaces among the billions of cells in our bodies. A solution of less than 10% salt water injected drop by drop into a vein can keep the human body alive after a serious loss of blood, or in case of shock, until nature repairs the damage. Salt sets the limits of our existence. Too much of it, or too little, means certain death. That is every animal's oldest memory—mystery and miracle enough for poets and prophets, seers and scientists.
