I left the translation of this part of the treatise, which, by the way, was far longer than all that I have given here, for a later opportunity. Unfortunately, I left Erewhon before I could return to the subject; and though I saved my translation and other papers at the hazard of my life, I was a obliged to sacrifice the original work. It went to my heart to do so; but I thus gained ten minutes of invaluable time, without which both Arowhena and myself must have certainly perished. I remember one incident which bears upon this part of the treatise. The gentleman who gave it to me had asked to see my tobacco-pipe; he examined it carefully, and when he came to the little protuberance at the bottom of the bowl he seemed much delighted, and exclaimed that it must be rudimentary. I asked him what he meant. “Sir,” he answered, “this organ is identical with the rim at the bottom of a cup; it is but another form of the same function. Its purpose must have been to keep the heat of the pipe from marking the table upon which it rested. You would find, if you were to look up the history of tobacco-pipes, that in early specimens this protuberance was of a different shape to what it is now. It will have been broad at the bottom, and flat, so that while the pipe was being smoked the bowl might rest upon the table without marking it. Use and disuse must have come into play and reduced the function to its present rudimentary condition. I should not be surprised, sir,” he continued, “if, in the course of time, it were to become modified still farther, and to assume the form of an ornamental leaf or scroll, or even a butterfly, while, in some cases, it will become extinct.” On my return to England, I looked up the point, and found that my friend was right. Returning, however, to the treatise, my translation recommences as follows:- “May we not fancy that if, in the remotest geological period, some early form of vegetable life had been endowed with the power of reflecting upon the dawning life of animals which was coming into existence alongside of its own, it would have thought itself exceedingly acute if it had surmised that animals would one day become real vegetables? Yet would this be more mistaken than it would be on our part to imagine that because the life of machines is a very different one to our own, there is therefore no higher possible development of life than ours; or that because mechanical life is a very different thing from ours, therefore that it is not life at all? “But I have heard it said, ‘granted that this is so, and that the vapour-engine has a strength of its own, surely no one will say that it has a will of its own?’ Alas! if we look more closely, we shall find that this does not make against the supposition that the vapour-engine is one of the germs of a new phase of life. What is there in this whole world, or in the worlds beyond it, which has a will of its own? The Unknown and Unknowable only!
