We have found, however, that a little marine wretch called the teredo attacks hemp so greedily that we've had to invent a new compound wherewith to coat it, namely, ground flint or silica, pitch, and tar, which gives the teredo the toothache, I suppose, for it turns him off effectually.
Around the same time, an invasive worm called the teredo ravaged the docks and pilings along the waterfront, and periodic fires wiped out most of the buildings.
This process took years, as the polyethylene glycol soaked into the wood and replaced the fibers of the wood lost to the ocean. unlike many ship wreck the Vasa was not attacked by teredo worms the bane to wooden ships before the advent of affixing a copper bottom.
Analysis of the wood revealed that it had been infested by teredo ship worms, which are native to the Caribbean.
The wooden pieces consisted of some side planks and a piece of a frame, while the metal pieces included bronze (copper) nails and pieces of the lead sheathing that would have protected the hull below the waterline from the wood-devouring teredo worm and rot.
A caterpillar also is engendered in hives, of a species nicknamed the teredo, or ‘borer’, with which creature the bee never interferes.
The refitting included covering the wooden hull with copper sheets to protect it from teredo worms and to discourage barnacles and other marine organisms from fouling (and thereby, slowing) the ship.
The protection was needed only during the time the caisson was afloat and before it was entirely submerged below the riverbed, where the sea worm, the teredo, never penetrates.
It was expected that the double solution, by forming an insoluble compound, would prove an effective protection against the _teredo_.
This merely confirms the general conclusion which has been stated under the head of creosoting, that nothing but the impregnation with creosote, and plenty of it, is an effectual protection against the _teredo_.
