Where does this word come from------ SHIT !!

Manure : In the 16th and 17th centuries, everything had to be transported by ship and it
was also before the invention of commercial fertilizers, so large shipments of manure
were quite common.

It was shipped dry, because in dry form it weighed a lot less than when wet, but once
water (at sea) hit it, not only did it become heavier, but the process of fermentation
began again, of which a by product is methane gas of course. As the stuff was stored
below decks in bundles you can see what could (and did) happen. Methane began to
build up below decks and the first time someone came below at night with a lantern,
BOOOOM!

Several ships were destroyed in this manner before it was determined just what was
happening  
After that, the bundles of manure were always stamped with the instruction ' Stow high
in transit ' on them, which meant for the sailors to stow it high enough off the lower
decks so that any water that came into the hold would not touch this volatile cargo and
start the production of methane.

Thus evolved the term ' S.H.I.T ' , (Stow High In Transit) which has come down through
the centuries and is in use to this very day..  You probably did not know the true history
of this word.  Neither did I.  I had always thought it was something to do with politicians.
.... Oh SHIT !
