Marker Text: ​Started here by early Spanish settlers; for making powder to hunt meat and resist Indians.
       Used charcoal made of wood of Hill Country from bat guano in such caves as longhorn caverns. Got saltpetre sulphur came by ox-cart or wagon from Mexico.
     These ingredients blended were highly explosive. Though powder was dampened during the work of grinding it fine, fires at the mill were not uncommon.
     In the Civil War, 1861-1865, supplied powder to state and frontier troops and the home guard. Workers were young boys and men past military age. (1965)
