Notes on the Recent Limestones of Cape Colony. 435 



There is no doubt that this cave has been made by the water 

 drained underground from the Strandveld, which is covered with 

 sand and limestone. The water, which is said locally to have 

 remarkable medicinal properties, tastes slightly brackish, and 

 apparently in no way differs from the spring water met with at 

 other places along the coast.
