Axe Grinding Stone Discovered

Fun day today: went down to the crick with Bob and Bob, the latter of whom had found a grinding stone in the water while fly fishing.  Given where it was, it is probably from an axe manufactory of the mid- to later nineteenth century.  Took a while to find it, but success as you can see here.

It is about 3ft. in diameter and 4in. thick.  Can't tell what kind of stone just yet as it is moss-covered.  Exciting remnant of a disappeared local industry:

Next step is to get it to the Bellefonte Historical Museum as an important part of our local industrial heritage.
