production of epic poems or great judicial harangues. So far from mankind being thrown out of work according to your notion," concluded Trost, with a peculiar nasal note of scorn, "if it were not for your incurable dilettanteism in science as in all other things—if you had once understood the action of any delicate machine—you would perceive that the sequences it carries throughout the realm of phenomena would require many generations, perhaps æons, of understandings considerably stronger than yours, to exhaust the store of work it lays open."
"Precisely," said I, with a meekness which I felt was praiseworthy; "it is the feebleness of my capacity, bringing me nearer than you to the human average, that perhaps enables me to imagine certain results better than you can. Doubtless the very fishes of our rivers, gullible as they look, and slow as they are to be rightly convinced in another order of facts, form fewer false expectations about each other than we should form about them if we were in a position of somewhat fuller intercourse with their species; for even as it is we have continually to be surprised that they do not rise to our carefully selected bait. Take me then as a sort of reflective and experienced carp; but do not estimate the justice of my ideas by my facial expression."
"Pooh!" says Trost. (We are on very intimate terms.)
"Naturally," I persisted, "it is less easy to you than to me to imagine our race transcended and superseded, since the more energy a being is possessed of, the harder it must be for him to conceive his own death. But I, from the point of view of a reflective carp, can easily imagine myself and my congeners dispensed with in the frame of things and giving way not only to a superior but a vastly different kind of Entity. What I would ask you is, to show me why, since each new invention casts a new light along the pathway of discovery, and each new combination or structure brings into play more conditions than its inventor foresaw, there should not at length be a machine of such high mechanical and chemical powers that it would find and assimilate the material to supply its own waste, and then by a further evolution of internal molecular movements reproduce itself by some process of fission or bud-
