The Earth, Vol. 2: A Descriptive History

Excerpt from The Earth, Vol. 2: A Descriptive History of the Phenomena of the Life of the Globe; ContinentsOn account of these partitions it is very difficult, or even impossible, to navigate the course of subterranean rivers to any considerable distance, even at the time the water is low. When it is high, the liquid mass, detained by the partitions, rises to a very high level in the large interior cavities, and often reaches the roof above. Some times when, through the clefts of the rocks, a communication exists between the cave and some hollow above, the surplus water from the subterranean streams makes its appearance there. Thus the Becca, which ows beneath the adjacent plateau of Trieste, does not always find space enough to ow freely in its lower channels, and Schmidl has seen it ascend in the chasms of Trebich to a height of 341 feet. It may be understood that the pressure of such a column of water often shatters enormous pieces of rock, and thus modifies the course bf underground streams.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
