ABSTRACT
The display of raw materials, manufactured products, machinery, tools and engines then brought together from the ends of the earth was a revelation to everyone; so busy had industrialists been in their own small spheres that they had not had time earlier to pause to take stock of progress generally. As far as the steam engine was concerned, these advances exerted a great influence upon its construction, but apart from that, its design was undergoing far-reaching changes. The beam type was disappearing, and its place was being taken by the slow-running horizontal engine. The greatest change amounting to a revolution during the period under review was caused by the advent of the steam turbine. The horizontal engine was frequently compounded by placing a high-pressure cylinder tandem with the low-pressure one on a common piston rod.
