Over the next few days, I kept careful tabs on Archimedes. He was always at something. While his peers were sitting around in the shade or engaged in games of tag, Archimedes walked around, picking up rocks and attempting to break them. I think he was looking for more rocks that made sharp edges, like the flint he’d made into a tool for his mother. There didn’t appear to be any flint in the area, so the tools were at a premium. It made me wonder where the flint had come from, though. I set an explorer drone the task of finding the nearest exposed flint deposits.
