Abstract
Recently on Shepherd's Knoll, my wife Elva and I spent the best part of three days laying up a stone wall (about one meter high and fifteen meters long) to border one side of a new vegetable garden. Many of the foundation and "topper" rocks were of the 50-150 pound variety and were maneuverable only with the use of a tractor and loader. We found that rock wall construction requires the integrative experiences of geology, physics, and philosophy. Since I am a biologist and my wife is an optometrist, our forays into the aforementioned disciplines of science were only amateur in nature.
