Floating islands, constructed of logs, or of wooden-stuff prepared in a similar manner, as is to be done with stone, and of live trees, which may be reared so as to interlace one another, and strengthen the whole, may be covered with gardens and palaces, and propelled by powerful engines, so as to run at an equal rate though seas and oceans. Thus, man may move, with the celerity of a bird’s flight, in terrestrial paradises, from one climate to another, and see the world in all its variety, exchanging, with distant nations, the surplus of productions. The journey from one pole to another may be performed in a fortnight; the visit to a transmarine country in a week or two; or a journey round the world in one or two months by land and water. And why pass a dreary winter every year while there is yet room enough on the globe where nature is blessed with a perpetual summer, and with a far greater variety and luxuriance of vegetation? More than one-half the surface of the globe has no winter. Men will have it in their power to remove and prevent all bad influences of climate, and to enjoy, perpetually, only that temperature which suits their constitution and feeling best.”

Who knows but by accumulating the power until the end of the present century, using meanwhile only the smallest allowance, reserving all that blows, all that shines, all that ebbs and flows, all that dashes, we may have got such a reserved accumulated power as to run the earth off its track into a new orbit, some summer, and so change the tedious vicissitude of the seasons? Or, perchance, coming generations will not abide the dissolution of the globe, but, availing themselves of future inventions in aerial locomotion, and the navigation of space, the entire race may migrate from the earth, to settle some vacant and more western planet, it may be still healthy, perchance unearthy, not composed of dirt and stones, whose primary strata only are strewn, and where no weeds are sown. It took but little art, a simple application of natural laws, a canoe, a paddle, and a sail of matting, to people the isles of the Pacific, and a little more will people the shining isles of space. Do we not see in the firmament the lights carried along the shore by night, as Columbus did? Let us not despair nor mutiny.

“The dwellings also ought to be very different from what is known, if the full benefit of our means is to be enjoyed. They are to be of a structure for which we have no name yet. They are to be neither palaces, nor temples, nor cities, but a combination of all, superior to whatever is known. Earth may be baked into bricks, or even vitrified stone by heat, — we may bake large masses of any size and form, into stone and vitrified substance of the greatest durability, lasting even thousands of years, out of clayey earth, or of stones ground to dust, by the application of burning mirrors. This is to be done in the open air without other preparation than gathering the substance, grinding and mixing it with water and cement, moulding or casting it, and bringing the focus of the burning mirrors of proper size upon the same.
