"But a change has now come over the affairs of mankind. Walled cities and empires have become unfashionable. The arm of commerce has borne away the gates of the strong city. Intelligence is penetrating the darkest corners of the globe. It makes its pathway over and under the sea, as well as on the earth. Wind, steam, and lightning are its chartered agents. Oceans no longer divide, but link nations together. From Boston to London is now a holiday excursion. Space is comparatively annihilated. Thoughts expressed on one side of the Atlantic are, distinctly heard on the other. The far off and almost fabulous Pacific rolls in grandeur at our feet. The Celestial Empire, the mystery of ages, is being solved."
