Abstract A range of pretreatment methods was applied to 6 known-age historical parchments to investigate the most suitable methods for effectively removing contamination and ensuring accurate radiocarbon dates while minimizing unnecessary destruction of potentially valuable historical documents.The methods tested included an acid wash, different concentrations of acid-base-acid (ABA) pretreatments, the current routine ABA method applied at the Oxford Radiocarbon Accelerator Unit (ORAU) that includes an additional bleach treatment, and extraction of collagen.
From there we would take a boat for the rest of the way, taking some goods and picking up some of the staff along the way, leaving more room in the vehicles to do the same.
When we got there was no boat, so we continued by road.
At this point the route becomes dust roads and whilst there hadn’t been a huge amount of rain, the rain that had fallen caused enough pot holes and some stretches were a little challenging to pass due to the soft, wet ground.
After a two and a half month break, which falls over the rainy season when all the properties close down, we all convened in Lusaka for the a pre-season briefing.
It was decided that we would head into the bush on the 2 March.
We like to have a month to re build all of the properties ready for opening on 1 April. We had two land cruisers and a land rover to drive down.
The original plan was for the girls to get to Gwabi, (near Chirundu, the border with Zimbabwe), and where the pontoon crosses over the Kafue River.
There are various myths/superstitions that surround the history of the baobab include: The Baobab Tree is also known as the tree of life.
It provides shelter, clothing, food, and water for the animal kingdom as well as humans.
The cork-like bark or huge stem is fire resistant and is used for making cloth and rope. The fruit, called “monkey bread”, is rich in vitamin C and is eaten and mixed into porridge or milk hence earning itself the name, monkey bread tree in some areas.
The tree is capable of storing hundreds of litres of water, which is tapped in dry periods.
