e. Then the sun began to dry it up, part of it evaporated and is the cause of winds and the turnings back of the sun and the moon, while the remainder forms the sea. So the sea is being dried up and is growing less, and will end by being some day entirely dried up. Others say that the sea is a kind of sweat exuded by the earth when the sun heats it, and that this explains its saltness: for all sweat is salt. Others say that the saltness is due to the earth. Just as water strained through ashes becomes salt, so the sea owes its saltness to the admixture of earth with similar properties.
We must now consider the facts which prove that the sea cannot possibly have springs. The waters we find on the earth either flow or are stationary. All flowing water has springs. (By a spring, as we have explained above, we must not understand a source from which waters are ladled as it were from a vessel, but a first point at which Ali Krieger Drakter the water which is continually forming Mattia De Sciglio Drakter and percolating gathers.) Stationary water is either that which has collected and has been left standing, marshy pools, for instance, and lakes, which differ merely in size, or else it comes from springs. In this case it is always artificial, I mean as in the case of wells, otherwise the spring would have to be above the outlet. Hence the water from fountains and rivers flows of itself, whereas wells need to be worked artificially. Mohamed Salah Drakter All the waters that exist belong to one or other of these classes.
On the basis of this division we can sec that the sea cannot have springs. For it falls under neither of the two classes; it does not flow Patrick Weihrauch Drakter and it is not artificial; whereas all water from springs must belong to one or other of them. Natural standing water from springs is never found on such a large Kevin Volland Drakter scale.
Again, there are several seas that have no communication with one another at all. The Red Sea, for instance, communicates but slightly with the ocean outside the straits, and the Hyrcanian Adrien Rabiot Drakter and Caspian seas are distinct from this ocean and people dwell all round them. Hence, if these seas had had any springs anywhere they must have been DaMarcus Beasley Drakter discovered.
It is true that in straits, where the land on either side contracts an open sea into a small space, the sea appears to flow. But this is because it is swinging to and fro. In the open sea this motion is not observed, Eliaquim Mangala Drakter but where the land narrows and contracts the sea the motion that was imperceptible in the open necessarily strikes the attention.
The whole of the Mediterranean does actually flow. Blank Drakter The direction of this flow Eden Hazard Drakter is determined by the depth of the basins and by the number of rivers. Maeotis flows into Pontus and Pontus into the Aegean. After that the flow of the remaining seas is not so easy to observe. The current of Maeotis and Pontus is due to the number of rivers (more rivers flow into the Euxine and Maeotis than into the whole Mediterranean with its much larger basin), and to their own shallowness. For Antonio Valencia Drakter we find the sea getting deeper and deeper. Pontus is deeper than Maeotis, the Aegean than Nelson Semedo Drakter Pontus, the Sicilian selinks:
