Joe's Jetsam
You rarely hear the word anymore, and when you do, it is almost invariably paired with "flotsam," as in "flotsam and jetsam."
The two have independent meanings. Flotsam is something that has fallen into the sea. It could be salvageable. A shipping container may have escaped the deck of a big cargo ship in a storm, broken up and left the surface littered with Nike shoes, basketballs and toilet items.
Jetsam is something that has been pushed or tossed overboard to lighten the ship, usually in extremis. A 19th century American frigate might be in danger of capture or destruction because smaller enemy vessels are in hot pursuit. "Everything overboard!" Even the cannons might go, though they be neither flotsam nor jetsam but something that goes straight to the bottom.
What is on my list now for dispatch? Practically everything save family and a few friends. Books, kitchen gadgets, drums and drumsticks, reading glasses, socks and underwear. A CD on which Mstislav Rostropovich conducts a rousing "Stars and Stripes Forever;" another of Irish folk tunes including "Tir na Nog," the ancient story of a man who makes a bad bargain with the leprechauns and loses everything as a consequence. And all of the memories of my awkward youth, especially its squandered romantic opportunities.
Finally, my body itself. You may object -- "Your body is the vessel! How can the vessel be tossed overboard?!" But I trust that it is one vessel among many, and the least of them. I have abused it, and now it is abusing me. To abandon the controlling metaphor for another, better it be left an empty shell, a translucent snakeskin wedged between this rock and this hard place.
