Volcanic cones, having no roots projecting downwards into the substratum to support them, would sink, and rupturing the crust around them, tend to perpetuate volcanic activity in the same region. The fissures would be formed around the cones, and thus a train of volcanos, originally linear, would give occasion to an elliptical ring of vents, to which the peculiar ghape of some of the coral archipelagoes may possibly be due. The existence of some kind of connection, between volcanic action and the elevation of continents, is indicated by the re- markable course of the great volcanic band which borders the Pacific ocean: for it approximately divides the world into two hemispheres, one of which contains nearly all the land, and the other, except Australia, is covered with water. Dut the course of this great band being turned aside by its junction with another, which comes from the N. W. through Sumatra and Java, the exceptional continental area of Australia Fas been elevated within the oceanic hemisphere, in connection with the thus abnormally deflected continuation of the great band. Our theory of volcanic action needs only the opening of fissures which shall reach the fluid substratum, without refer- ence to how those fissures may be caused. We think thercfore that the present localization of volcanic activity, at interrupted regions along the flank of an elevated range, may be traccu to the deposition of sediment, evea ai a considerable distance, upon the side of the range opposite to thas on which the volcanos lie. An inspection of our diagram on page 132 will explain how this would be: and there appears some reason to suppose that this suggestion is supported by geographical facts. a “dD YO Mi a OR |e es eM eee,
