Land Battle Re-enactment of the French and Indian War at Ogdensburg July 22, 2012

Land Battle Re-enactment of the French and Indian War at Ogdensburg – July 22, 2012

Each July the folks of Ogdensburg, New York turn the clock back a few hundred years on a piece of open land at Lighthouse Point on the banks of the St. Lawrence River in order to welcome re-enactors interested in the skirmishes that occurred in the 18th century when this piece of property was the site of Fort de la Presentation. They are hoping that some day they will have been able to raise sufficient funds to begin a reconstruction of the fort itself as a tourist site of historical and educational interest. More information about Fort de la Presentation is here.

As the beginning of the land battle draws closer, cannons roll in, the drummers start drumming and the troops assemble in period clothing ready to do battle. Lots of noise and smoke as the black powder artillery adds to the drama of the re-enactment.

Tennessee Aquarium, Chattanooga, Tennessee (Part III)

In the River Journey building, you start your tour in the lower levels where there is a wonderful display of seahorses but first I had to get past the Horseshoe Crab (Limulus polyphemus) which, I guess, was the display creature of the day. For those who need to know such things, the horseshoe crab is ‘bled’ to obtain Limulus amebocyte lysate (LAL) which is an aqueous extract of amoebocytes. LAL reacts with bacterial endotoxin or lipopolysaccharide and it is this reaction which is the basis of a test called the LAL test. The LAL test is used in the pharmaceutical industry to detect the presence of, or quantity of, gram negative bacteria endotoxins. Prior to acceptance of this test, a rabbit test was used for this quality testing purpose. When I was an inspector of parenteral drug manufacturing sites back in the ’70s, this LAL test was still considered a new test method and was still undergoing validation procedures in parallel to testing in rabbits. I think that the ladies showing me their horseshoe crab were a bit surprised that I knew this much about their horseshoe crab:-). I was surprised at how little I had forgotten in 30 years! LOL

Tennessee Aquarium, Chattanooga, Tennessee (Part II)

Penguin swimming

The first part of this multi-part posting of my visit to the Tennessee Aquarium focused on the orchids and butterflies exhibits and a few of stingrays on exhibit. This Part II highlights the reefs and the jelly fish displays. The jelly fish are a bit tough to photograph because they are in constant motion but I was surprised by the number of different varieties that the Tennessee Aquarium had on display and the amount of aquarium space that they had allocated to displaying these interesting creatures. Part III covers the “River Journey” building.
