Ornaments fashioned out of spar and stalactites have also a considerable sale.
The dissipation of the dissolved carbon dioxide results in the formation of "fur" in kettles or boilers, and if the solution is falling, as from the roof of a cave, in the formation of stalactites and stalagmites.
At some period, long subsequent to its original excavation, and after many large stalactites had grown, it was completely filled with glacial mud charged with acid, whereby the dripstone was eroded into singularly grotesque shapes.
Several stalactites in the Giant Hall exceed 50 ft.
The whole cut impressed me as if it were a cave with its stalactites laid open to the light.
