In another of these nondescript papers, "The Conversation of Eiros and Charmion," Mr Poe has very boldly undertaken to figure forth the destruction of the world, and explain how that great and final catastrophe will be accomplished. It is a remarkable instance of that species of imaginary matter of fact description, to which we have ventured to think that the Americans show something like a national tendency. The description here is very unlike that with which Burnet closes his "Theory of the Earth;" it is confined to the natural history of the event; but there is nothing whatever in Mr Poe's manner to diminish from the sacredness or the sublimity of the topic. With some account of this singular and characteristic paper we shall dismiss the volume of Mr Poe. The world has been destroyed. Eiros, who was living at the time, relates to Charmion, who had died some years before, the nature of the last awful event. "I need scarcely tell you," says the disembodied spirit, "that even when you left us, men had agreed to understand those passages in the most holy writings which speak of the final destruction of all things by fire, as having reference to the orb of the earth alone. But in regard to the immediate agency of the ruin, speculation had been at fault from that epoch in astronomical knowledge in which the comets were divested of the terrors of flame. The very moderate density of these bodies had been well established. They had been observed to pass among the satellites of Jupiter without bringing about any sensible alteration either in the masses or in the orbits of these secondary planets. We had long regarded the wanderers as vapoury creations of inconceivable tenuity, and as altogether incapable of doing injury to our substantial globe, even in the event of contact. But contact was not in any degree dreaded; for the elements of all the comets were accurately known. That among _them_ we should look for the agency of the threatened fiery destruction, had been for many years considered an inadmissible idea. But wonders and wild fancies had been, of late days, strangely rife among mankind; and although it was only with a few of the ignorant that actual apprehension prevailed upon the announcement by astronomers of a _new comet_, yet this announcement was generally received with I know not what of agitation and mistrust.
