Civil War for the day

islandpacket.com has an article by Bruce Smith about the Hunley:

Scientists using small air-powered chisels and dental tools have begun the laborious job of removing encrusted sand, sediment, and rust from the hull of the Confederate submarine H.L. Hunley, the first submarine in history to sink an enemy warship.
It will take about a year of painstaking work (photo) to reveal the hull of the hand-cranked sub for the first time in a hundred and fifty years. The hull may provide the final clues as to why the Hunley sank off Charleston, South Carolina in February of 1864, after sending the Union blockade ship USS Housatonic to the bottom.
"We will probably be closer" to knowing why, said Stephanie Crette, the director of the Warren Lasch Conservation Center, part of Clemson University's Restoration Institute in North Charleston, a few miles from where the Civil War began at Fort Sumter in Charleston harbor.
Any damage to the hull of the forty-foot sub might explain the sinking. "We will have a better understanding of how it was built and what happened to it," said Nestor Gonzalez-Pereyra, the center's associate director.
The sub and its crew of eight set off a powder charge at the end of a spar, sinking the Housatonic, as the Confederacy tried to break a Union blockade of Charleston late in the war. The Hunley sank and never returned.
The sub was discovered in 1995 and raised and brought to the lab in 2000. Later the silt-filled interior was excavated and the remains of the crewmen removed. They were buried in 2004 in Charleston in the last Confederate funeral.
Last year, scientists announced it appears the charge that sank the Housatonic was attached to a sixteen-foot spar at the front of the Hunley. They speculated that could mean the crew was knocked unconscious and the sub damaged by the shock wave from the explosion.
At the time the Hunley was raised, historians thought it was farther away from the Housatonic, and speculated the crew ran out of air before they could crank back to the coast.
Since early May of 2014, the Hunley has been bathed in a solution of sodium hydroxide to loosen the encrustation coating the hull and interior. Now conservationists will work by hand on the sub for six hours a day, three days a week. They will work, sometimes in the cramped interior of the sub, wearing goggles, boots, and gloves. When they are not working, the seventy-six-thousand-gallon tank in which the Hunley sits will be refilled with the chemical.
Plans call for the Hunley to eventually be displayed in a forty-million-dollar museum not far from the lab where it is being conserved. The Hunley Commission earlier this year agreed to establish a museum authority to oversee the construction.

Rico says it's a lot of money for a rusted old piece of history...
