Veon, Inc. mined fire clay of the plastic variety from open pits and marketed the output for use in manufacturing fire brick and block, foundries, and heavy clay products. In addition, Ralph A. Veon, Inc., mined and sold fire clay of the burley variety.

On Beaver Creek was manufactured paper and birch oil. A kind of clay has been found from which chinaware is made. A pottery was also operated in the vicinity. A granite, very much like Vermont granite, is found near New Jerusalem. There is a marble saw mill on the Sacony near Grim's mill, where large blocks of marble are sawed into desirable sizes. It has been in operation since 1864. None of the early mines are now in operation.
