Let us see: One of the coldest regions of the earth is Siberia. It is a vast tract reaching to the Arctic Circle; it is the north part of the Continent of Asia; it is intersected by great mountain-ranges. Here, if anywhere, we should find the Drift; here, if anywhere, was the ice-field, "the sea of ice." It is more elevated and more mountainous than the interior of North America where the drift-deposits are extensive; it is nearer the pole than New York and Illinois, covered as these are with hundreds of feet of _débris_, and yet _there is no Drift in Siberia!_ I quote from a high authority, and a firm believer in the theory that glaciers or ice-sheets caused the drift; James Geikie says: "It is remarkable that _nowhere in the great plains of Siberia do any traces of glacial action appear to have_ {p. 29} _been observed._ If cones and mounds of gravel and great erratics like those that sprinkle so wide an area in Northern America and Northern Europe had occurred, they would hardly have failed to arrest the attention of explorers. Middendorff does, indeed, mention the occurrence of trains of large erratics which he observed along the banks of some of the rivers, but these, he has no doubt, were carried down by river-ice. The general character of the 'tundras' is that of wide, flat plains, covered for the most part with a grassy and mossy vegetation, but here and there bare and sandy. Frequently nothing intervenes to break the monotony of the landscape. . . . It would appear, then, that ill Northern Asia representatives of the glacial deposits which are met with in similar latitudes in Europe and America _do not occur_. The northern drift of Russia and Germany; the åsar of Sweden; the kames, eskers, and erratics of Britain; and the iceberg-drift of Northern America have, apparently, no equivalent in Siberia. Consequently we find the great river-deposits, with their mammalian remains, which tell of a milder climate than now obtains in those high latitudes, still lying _undisturbed at the surface_."[1] Think of the significance of all this. There is no Drift in Siberia; no "till," no "bowlder-clay," no stratified masses of gravel, sand, and stones. There was, then, no Drift age in all Northern Asia, _up to the Arctic Circle!_ How pregnant is this admission. It demolishes at one blow the whole theory that the Drift came of the ice. For surely if we could expect to find ice, during the so-called Glacial age, anywhere on the face of our planet, it would be in Siberia. But, if there was an ice-sheet there, it did not grind up the rocks; it did not striate them; it did not roll the fragments into bowlders and pebbles; it rested so quietly on the face of the land that, as Geikie tells us, the pre-glacial deposits throughout Siberia, with their mammalian remains, are still found "_lying undisturbed_ [1.
