NDICATIONS along vast stretches of the coast-hnes of theworld familiar to all geologists and to many laymen areexplicable only on the theory that either the ocean or theland has changed its level. In places there are great drownedvalleys, like that of the Hudson, which runs beneath NewYork Bay and out to sea. Here the land has sunk or thewater has risen. Elsewhere there are sea-beaches, hundredsof feet up on hillsides, showing an elevation of the land ora dropping of the water-level. Which has moved in aU thesecases—the land or the water? Geologists are still debating. ZUIDER ZEE—HOLLANDS LATEST REALTY DEVELOPMENT. this question. A recent French writer believes that the land isresponsible, largely because we may suppose one portion of thecoast to have risen and another to have sunk simultaneously,while the ocean must have maintained the same average leveleverywhere. Says a writer in the Revue Scientifique (Paris,November 2-9): It is well known that throughout most of western Europeand northern Africa the recent investigations of geologists havingto do with questions relating to the Quaternary period have beenable to show the existence of alluvial terraces at well-determinedlevels, practically constant throughout this vast region of theglobe. Their existence can be explained only by a relative move-ment of the oceans and the continents. The difficulty, however,is to ascertain whether we have to do onlj^ with oscillations ofsea-level or with phenomena of elevation and depression of con-tinental masses. A recent work of Mr. Jole
