From a website dedicated to mining in Pribram:

HORNICTVA NA PRÍBRAMSKU
Ješte ze staré Príbrame
"Druhou flusárnu měl roku 1685 mlynář Martin Mohelnický u rybníka Obory."
It means: Miller Martin Mohelnicky had the second workshop for potash production, which was located by the Obora pond.
Note: The Mohelnicky potash workshop is mentioned in birth registries dated 1733.
See the nobility page for more about Martin.
