Each and every loss becomes an instance of ultimate tragedy-something that once was, but shall never be known to us. The hump of the giant deer-as a nonfossilizable item of soft anatomy-should have fallen into the maw of erased history. But our ancestors provided a wondrous rescue, and we should rejoice mightily. Every new item can instruct us; every unexpected object possesses beauty for its own sake; every rescue from history's great shredding machine is-and I don't know how else to say this-a holy act of salvation for a bit of totality.
