By noon today one can see four big operations going on. The trucks are rumbling in dirt from the excavation job in front of the Heights. The dirt goes, of course, onto the floor of the depression where it is immediately worked on under the watchful eye of a supervisor. Two excavators are at work digging a trench for more pipe laying, while on the other side of the academy an excavator is busy removing one more tree as well as some dirt at the east end of the theater site. The curious thing in today’s observations is one of the tools being used by a trench excavator. The usual bucket lies to the side, and attached to the arm of the machine in its place is a cylinder with cone shaped projections. This cylinder spins as it is lowered into the trench. Is it loosening the dirt down there so the other excavator can remove it more easily, or is it acting as a miniature compactor at the bottom of the trench, or is it doing some other task unknown to this observer? There is no one handy to ask.
