10. The slow, gradual, and periodical displacement of the sea is a fact proved by experience, attested by numerous examples at all points of the globe. In this manner it keeps in repair the productive forces of the Earth. This long immersion is a time of repose, during which the submerged Earth recuperates the vital principals exhausted by a no shorter period of production. The immense deposits of organic matter brought by the waters from age to age are natural composts periodically renewed; and generations succeed generations without perceiving these changes. *
* Among the most recent facts proving the displacement of the sea, one can cite the following: In the Gulf of Gascogne, between the old Souillac and the tower of Cordova, when the sea is calm, one discovers in the water’s depths pieces of wall. These are the remains of the great and ancient city of Noviomagus, invaded by the water A.D. 580. The rock of Cordova, which then joined the shore, is now twelve kilometers from it. By La Manche, upon the Havre side, the sea gains every day upon the earth, and undermines the cliffs of St. Andres, which are gradually crumbling. Two kilometers from the shore, between St. Andres and Cape Hague, exists the bank of L’Eclat, in olden time dry ground and united to terra firma. Ancient documents state that upon this ground where one can sail upon the water today was the village of St. Denis-chef-de-Caux. The sea having invaded the land during the fourteenth century, the church was engulfed in 1378. It is pretended that in a calm tide the remains of it can be seen in the waters. Upon nearly the whole extent of the coast of Holland the sea has been restrained only by dikes, which give way from time to time. The ancient Lake Fleno, united with the sea in 1255, forms today the Gulf of Zuyder-Zee. This eruption of the ocean submerged many villages. Judging from this, Paris and, indeed, all of France, will some day be again occupied by the sea, as it has already been many times, as geological observations prove. The mountainous regions will then form islands like Jersey, Guernsey, and England, formerly contiguous to the continent. The countries now traversed by railroads will then be sailed over. Ships will stop at Montmartre, at Mount Valerian, on the shore of St. Cloud and Meudon. The woods and forests through which we now promenade will be buried under water, covered again with earth, and inhabited by fish instead of birds. The biblical deluge cannot have been caused in this way, since the invasion of the waters was sudden and their sojourn short; otherwise, it would have lasted many thousand years, would still exist without men knowing of its occurrence.
