Alas! in the present state of science, we must take the finished articles away; but think not that man will always be the victim of circumstances.
The countryman who visited the city, and found the streets cluttered with bricks and lumber, reported that it was not yet finished; and one who considers the endless repairs and reforming of our houses might well wonder when they will be done. But why may not the dwellings of men on this earth be built, once for all, of some durable material, some Roman or Etruscan masonry, which will stand, so that time shall only adorn and beautify them ? Why may we not finish the outward world fur posterity, and leave them leisure to attend to the inner? Surely, all the gross necessities and economies might be cared for in a few years. All might be built and baked and stored up during this, the term-time of the world, against the vacant eternity, and the globe go provisioned and furnished, like our public vessels, for its voyage through space, as through some Pacific Ocean, while we would "tie up the rudder and sleep before the wind," as those who sail from Lima to Manilla.
