Putting the world back together

We wallers, more than other professions perhaps, sometimes feel like we are merely fitting parts of the geological universe back together. I'm working on an island in Muskoka Ontario this week and admiring the nice fits in the exposed bedrock that nature starts with. I see evidence of rocks beginning to form and split up from their tight fitting configurations and drift apart. I imagine they eventually leave home, go their separate ways, and much later, they employ us to reunite them again somewhere else in this crazy puzzling world into lovely dry stone walls.
