Dr. Mathews: When sailing ships from Great Britain of England found the continent of the United State we were very happy to find one thing that we desperately needed, trees. Very very large trees. Trees remember are very important for military reasons. Remember England is an island, so if you want to go out and conquer the world, you need a navy. A navy requires wood. And the bigger the trees there are, the bigger the boats you can build with larger guns. And so we were very happy to find very large trees in American which we could take back and use in our ship building processes. Well the trees you see here now in Pennsylvania are essentially third generation of clear cutting. Originally the forest would have been very different. And in fact there is a company out, I think, in the lakes of Minnesota, where they were found large submerged logs. And they would bring then up with cranes and sell them at market. What makes this wood so valuable and worth the effort, is it was part of the original forest, the first clear cutting. In those days a canopy was very very thick. And so the trees tending to grow slower because they received less light. Therefore the rings were much more close together. And the grain or the beauty in the wood in the furniture making process is much richer and highly more valued. And so these trees could be worth a hundred-thousand dollars.
