It was only in 1840 that the Archimedes was fitted as a screw yacht.

As regards this country, though its institutions are old, modern England is still young.

As respects its mechanical and scientific achievements, it is the youngest of all countries.

Watt's steam engine was the beginning of our manufacturing supremacy; and since its adoption, inventions and discoveries in Art and Science, within the last hundred years, have succeeded each other with extraordinary rapidity.
