I must acknowledge, however, that all these arguments fail of convincing a few geologists of the doctrine of internal igneous fluidity, to the extent above described. But they all admit that the facts do prove the existence of vast oceans of melted matter beneath the earth's crust. Nor do even these geologists doubt but the globe contains within itself the agencies requisite for a universal conflagration. Mr. Lyell says that "there must exist below enormous masses of matter, intensely heated, and in many instances in a constant state of fusion." He says, also, "When we consider the combustible nature of the elements of the earth, so far as they are known to us, the facility with which their compounds may be decomposed and made to enter into new combinations, the quantity of heat which they evolve during those processes; when we recollect the expansive power of steam, and that water itself is composed of two gases, which, by their union, produce intense heat; when we call to mind the number of explosive and detonating compounds which have been already discovered,--we may be allowed to share the astonishment of Pliny, that a single day should pass without a general conflagration. '_Excedit profecto omnia miracula, ullum diem fuisse quo non cuncta conflagrarent._'"--Lyell's _Principles of Geology_, b. ii. chap. xx. vol. ii. "As a consequence of the refrigeration of the centre and crust of the globe," says D'Orbigny, "the withdrawment of matter has produced elevations and depressions on the consolidated crust; to which movements, in connection with those of the waters, we must impute the complete destruction of the existing fauna. These dislocations have brought about at each epoch changes of level in the consolidated beds and in the seas. And after a period of agitation, more or less prolonged, after each of these geological revolutions, different beings have been created to cover anew and enliven the surface of the earth."--_Cours Elementaire Paleontologie_, p. 148. All geologists, then, agree that the elements of the earth's final conflagration are contained within its bosom or upon its surface. At present, these elements are so bound down by counteracting agencies, that all is quiet and security. But let the fiat of the Almighty go forth for their liberation, and the scenes of the last day, as described in the Bible, will commence. The ploughshare of ruin will be driven onward, until this fair world is all ingulfed, and no trace of organic life remains. Yet to him who realizes that the destruction is only a necessary preparation for a brighter world, which will emerge from the ruins of the present; that, when the matter of the globe has been purified, its surface shall be covered with new and lovelier forms of beauty, surrounded by a still more bland and balmy atmosphere, and inhabited by sinless and immortal beings,--to him who realizes all this, the desolation will put on the aspect of a glorious transformation.
