English: Plate XXV of 1898 publication called Maryland Geological Survey Volume Two, with caption "
Serpentine.
Broad Creek,
Harford County." Width of the field is approximately 10.7 cm.
The text of the volume refers to the plate:
Serpentine or "Verde Antique" has been quarried in Maryland for many years, but the annual production has always remained small. As this rock enters into competition with some of the marble for interior decoration it has frequently been classed as a marble, although so far as the Maryland deposits are concerned it is in no wise related to the marble, however intimately interwoven with calcite veins it may be. The deposits of the state are found in Cecil, Harford, Baltimore, Howard and Montgomery counties, where they have been worked to a greater or less extent in the hope of obtaining good material for general building or interior decoration . The most thoroughly exploited are those about Baltimore, at the Bare Hills, those on the banks of Broad Creek in the eastern part of Harford county, and a small area near Cambria in the northern part of the same county. That the stone is capable of furnishing beautiful slabs for decorative purposes is readily seen from the accompanying illustration (Plate XXV). The deposits on Broad Creek are situated in the midst of a large serpentine area, which extends from the Susquehanna south westerly into Baltimore county. The nearest town is the small village of Dublin some three miles to the south, which is lacking in both railroad and canal communication. In the shipping of orders it is necessary to have all of the stone hauled to Conowingo on the Perryville and Columbia Railroad, a distance of three or four miles.
