Sorry, no etymologies found.
The veins of it are difficult to distinguish from the calcite, as they are almost identical in color, and many of the calcite veins are partly of pectolite -- in fact, every third or fourth vein will contain more or less of it.
There is, however, a very fine vein of pectolite about twenty-five feet further east from the natrolite bed; it runs from the floor to ceiling, and is about two inches in thickness; some specimens of which I took from these were unusually unique in both size and appearance.
Considerable quantities of pectolite may generally be found on the dump, but also in Shaft No. 1, and especially No. 2.
