The invention of the Steam Engine has been productive of so great a change in the arts and conveniences of life, that it may with justice be regarded as an era in the liistory of the world. It is true that other inventions have raised the intellectual greatness of man, far beyond the anticipations of rational conjecture; that they have enabled him to number the stars, to describe their motions, and bring within the grasp of his faculties those myriads of orbs, which had been esteemed far beyond the conipass of his vision,—to direct his way unerringly across the pathless ocean,-to stop the course of rivers,—to convert the shallow brook into a spacious navigable canal,—to fertilise the barren rocks,-and change the unfrequented desart into the active theatre of his genius!
